[0019]在多个特征之中,该方法和系统提供了快速并且容易地获取表示物体的颜色和3D形貌数据的特征。 [0019] Among the plurality of features, the method and system provides a fast and easy access to the color of an object showing characteristics of the data and the 3D topography. 例如,该方法和系统能够用于收集聚焦并且精确地表示物体的2D彩色图像。 For example, the method and system can be used to collect and focus accurately represent the color 2D image of the object. 另外,能够实时并且与2D彩色图像数据结合地生成物体的表面的3D形貌数据。 In addition, real-time and is combined with the color image data to generate 2D 3D surface topography data of the object. 在一个方面中,能够处理3D形貌数据和2D彩色图像数据并且将其结合在一起以输出到显示器,以供用户观看。 In one aspect, the processed 2D and 3D topography data and color image data, which joined together to output to the display, for users to watch. 至少部分地(in-part)基于在这里描述的方法和系统,提供了新的和改进的方法以生成能够与对应于物体的3D图像数据叠加的物体的聚焦彩色图像(例如,RGB图像)。 At least partially (in-part) based on the methods and systems described herein, provides a new and improved method to generate a focus color image (e.g., RGB image) capable of corresponding to the object of 3D image data superimposed objects. 在不在共享的时间周期内执行彩色成像和3D数据获取二者的现有的途径中,考虑到操作者的方便和/或病人的舒适度,单独地获取彩色图像和单独地进行3D形貌扫描所需的总时间可能比预期要长。 Existing ways for color imaging and 3D data is not shared within the period of time to obtain the two, considering the convenience of the operator and / or patient comfort, individually and separately to obtain color images of 3D topography scan the total time required may be longer than expected. 另外,当采用手持成像扫描仪时,优选地在接近的相同时间内进行彩色图像的获取和3D形貌扫描的获取,从而避免扫描仪的可能的不利移动。 In addition, when using a handheld imaging scanner, preferably at the same time close to obtaining and 3D topography scanned color image acquisition, thereby avoiding possible adverse scanner movement. 与这样的现有途径相反地,在这里公开的方法和系统能够用于在共享的时间周期内获取彩色图像和进行3D形貌扫描,从而减少了所需时间的总量,并且作为减少时间总量的结果帮助避免了扫描仪的不利移动,并且结果能够在大致相同时间获得物体的部分的彩色图像数据和3D形貌数据。 Such contrast with conventional ways, where the disclosed method and system for acquiring a color image and can be scanned in a shared 3D topography period of time, decreasing the amount of time required, and for reducing the total time results the amount helped to avoid unwanted movement of the scanner, and the results can be obtained the color image data portion of the object and the 3D topography data at substantially the same time.

[0020]能够成像任意适当类型的物体。 [0020] Imaging can be of any suitable type of object. 在一个实施例中,扫描方法和系统能够用于生成表示病人的牙齿的图像。 In one embodiment, the scanning method and system can be used to generate an image showing the patient's teeth. 例如,能够扫描病人的一些或全部牙齿,并且对用户提供显示。 For example, it is possible to scan the patient some or all of the teeth, and provide a display to the user. 例如,使用3D形貌数据,能够显示并且管理病人的牙齿的3D虚拟模型,例如,以有助于牙科诊疗中的牙齿从业者。 For example, the use of 3D topography data can be displayed and management of patients with dental 3D virtual model, for example, in order to contribute to dental treatment in dental practitioners. 在一些情况下,例如,3D虚拟模型能够用于定义病人的牙齿的空间关系,以定义如何制造成型为适合特殊病人的假牙(例如,牙冠和齿桥)。 In some cases, e.g., 3D virtual model can be used to define the spatial relationship between the patient's teeth, shaped to define how to make dentures to fit particular patient (e.g., crown and bridge). 除了显示3D虚拟模型之外,在这里描述的方法和系统提供了显示病人的牙齿的颜色信息。 In addition to displaying 3D virtual model than the methods and systems described herein provide a display of the patient's tooth color information. 例如,能够通过颜色容易地区分牙龈和牙齿,并且颜色信息还能够与3D形貌数据结合以产生能够与3D形貌数据结合的聚焦彩色图像,从而生产彩色3D虚拟模型。 For example, gums and teeth can be divided by color easily identified, and the color information can also be combined to produce a 3D topography data can be combined with the focused color image and 3D topography data, thereby producing a color 3D virtual model. 还能够共享和存储通过该系统和方法生成的数据,从而在稍后传送或输出到例如能够用于制作虚拟设计的假牙的物理模型和/或物理复制品的制造装置。 Also be able to share and store the resulting data through the system and method, which later transferred to, for example, or output device can be used to make dentures physical modeling virtual design and / or physical copies.

[0021]在一个方面中,提供了用于生成物体的聚焦彩色图像的系统。 [0021] In one aspect, the object is provided for generating a color image of the focusing system. 该系统能够包括多色光源,例如,该多色光源能够用于产生用于生成彩色图像的光。 The system can include a polychromatic light source, e.g., the polychromatic light source for generating light can be used to generate a color image. 多色光能够从物体的表面被反射,而后成像以产生彩色图像。 Multi-color light can be reflected from the surface of the object, and then imaged to produce a color image. 为了有助于产生彩色图像,该系统能够包括:光学系统,该光学系统光学结合到光源,从而使多色光聚焦于第一焦平面和第二焦平面,其中,第一焦平面包括一个颜色(例如,红色),并且第二焦平面包括另一个颜色(例如,绿色)。 To help produce a color image, the system can include: an optical system, the optical system is optically coupled to a light source, so that the polychromatic light focused on the focal plane of the first and second focal plane, wherein the first focal plane including a color ( For example, red), and the second focal plane further comprises a color (e.g., green). 在一些实施例中,第三颜色(例如,蓝色)能够聚焦于第三焦平面。 In some embodiments, the third color (e.g., blue) can be focused on a third focal plane. 能够在物体的表面上扫描不同颜色的光的焦平面,并且能够反射不同颜色的光,以使得能够收集表示物体的表面的彩色图像数据。 Capable of scanning the surface of the object focal plane of light of different colors, and is capable of reflecting light in different colors, to enable the collection represents the color image data of the object surface. 在一些方面中,该系统能够包括检测器,该检测器构造成收集扫描过程中的不同时间点的彩色图像数据。 In some aspects, the system can include a detector, the detector is configured to scan a color image data collected at different points of time. 例如,能够在第一时间点收集对应于多色光源的一个颜色(例如,红色)的图像数据。 For example, it is possible to collect a color corresponding to a polychromatic light source (e.g., red) of the image data in the first time point. 能够在第二时间点收集另一个颜色(例如,绿色)的图像数据。 You can collect another color (e.g., green) of the image data in the second time point. 部分地由于红色和绿色的焦点的不同的Z位置,绿色图像数据能够在红色图像数据不聚焦时聚焦。 Partly due to the different Z-position of the focal point of the red and green, green when the image data can not focus on the red image data in focus. 随着在扫描过程中扫描焦平面,红色焦点能够移动,使得红色图像数据聚焦并且绿色不聚焦。 As the focal plane scanned during the scanning process, the focus can be moved in red, so that the red and green image data is not focused focus. 然后,能够利用构造成将彩色图像数据结合以生成物体的聚焦彩色图像的处理器,来处理收集的聚焦红色和绿色图像的图像数据。 Then, use can be configured to combine the color image data to generate a color image of the object focused processor to process the image data of red and green image focus collected.

[0022]在一些实施例中,例如,能够通过收集其中每个颜色独立聚焦的在不同时间点处的多色光的每个颜色的颜色数据的聚焦图像数据而产生聚焦彩色图像。 [0022] In some embodiments, e.g., where the in-focus image by collecting separate data for each color in the focused polychromatic light of each color at different time points of the color data and generating a focus color image. 假定不同的颜色能够处于不同的焦平面中,因为物体将位于一个颜色的焦平面而不是另一个颜色的焦平面的附近,所以一个颜色可能聚焦,而另一个颜色不聚焦。 Different colors can be assumed at different focal planes, since the object will be located in the focal plane of a color close to the color rather than another focal plane, so that a color may focus, while the other colors are not the focus. 根据与物体相关的不同颜色的光的位置(例如,各个不同颜色的焦平面),能够从物体生成并且收集一个颜色(例如,红色)的聚焦图像数据。 The optical position of the object associated with the different colors (e.g., different colors of the focal plane), the object can be generated and collected from a color (e.g., red) of the image focus data. 在一个颜色的收集时间点,在聚焦颜色数据中可能不产生另一个颜色(例如,蓝色)。 Collection point in time one color, the color data in focus may not produce another color (e.g., blue). 代替地,能够在物体的扫描中的不同时间点收集另一个颜色(例如,蓝色)的聚焦图像数据,使得另一个颜色聚焦并且一个颜色(例如,红色)不聚焦。 Instead, it is possible to scan the object at different time points in the collection of another color (e.g., blue) focused image data, so that the focus of another color and a color (for example, red) focus. 然后,能够将各个时间点的聚焦彩色图像数据结合以产生聚焦的红蓝图像。 Then, the color image can be focused at various time points of data are combined to produce a focused image of red and blue. 其它颜色组合也能够用于生成例如物体的实际RGB图像。 Other color combinations can be used to generate images of the object such as the actual RGB.

[0023]多种成像系统能够用于产生聚焦彩色图像,如在这里所描述地。 [0023] The imaging system can be used to generate multiple focused color images, as described herein manner. 能够使用在不同的焦平面产生不同颜色的成像系统。 It can be used to produce different colors at different focal planes of the imaging system. 能够在物体的表面上扫描与不同颜色关联的不同的焦平面,以从表面生成反射。 Scanning can be associated with different colors on different focal planes in the surface of the object to produce reflected from the surface. 能够使用检测器收集并且成像彩色反射,并且然后处理以产生聚焦图像。 It can be used to collect and the imaging detector color reflection, and then processed to produce a focused image. 例如,该处理能够包括选择不同时间点的不同颜色信息,例如,其中一个颜色在一个时间点聚焦,并且另一个颜色在另一个时间点聚焦。 For example, the process can include selecting a different color information at different time points, for example, one color at a time point of focus, focus on another color and another point in time. 一个颜色的聚焦图像数据能够与另一个颜色的聚焦图像数据结合,从而产生包括两个颜色的颜色数据的聚焦图像。 A focused image data is color image data and the focus can be another color combination, resulting in two colors including color data focused image. 相似地,这能够应用于多色构造。 Similarly, this structure can be applied to multi-color. 例如,能够结合红色、绿色和蓝色图像的聚焦图像数据以形成聚焦RGB图像。 For example, to combine red, green and blue image-focus image of the RGB image data to form a focus.

[0037] 在一些实施例中,成像装置200中的光学器件和多色光源216的结合能够构造成产生用于光的不同颜色的不同焦平面。 [0037] In some embodiments, the image forming apparatus 200 combined with the optics and polychromatic light source 216 can be configured to generate different focal planes for different colors of light. 例如,焦平面能够对应于能够用于扫描物体的表面的红色(R)、绿色(G)和蓝色(B)光。 For example, corresponding to the focal plane can be used to scan the surface of an object of red (R), green (G) and blue (B) light. 如图2所示,红色光、绿色光和蓝色光的焦平面能够沿着轴设定在不同位置处。 2, red light, green light and blue light in the focal plane can be set at different positions along the axis. 例如,具有红色光的XY平面能够位于Z轴的一个位置处,具有绿色光的XY平面能够设定在Z轴的另一个位置处,并且具有蓝色光的XY平面能够设定在Z轴的另一个位置处。 For example, the XY plane with red light can be located at a position where the Z axis, the XY plane with green light can be set in another position of the Z axis, and the blue light having the XY plane can be set in the Z-axis of the other a position.

[0038]不同焦平面的不同颜色的相对位置能够取决于多种因素,诸如光的颜色、光学部件的折射率、和/或能够使不同颜色在不同焦平面聚焦的放大色差的光学器件的使用。 [0038] the relative positions of different colors of different focal plane can depend on various factors such as the use of the color of light, the refractive index of the optical components, and / or capable of different colors at different focal plane of the focusing magnification chromatic aberration optics . 在一些方面中,取决于光的颜色(或波长)的不同焦平面能够使用各种技术产生。 In some aspects, depending on the color of light (or wavelength) different focal planes can be produced using various techniques. 在一个实施例中,来自透镜或其它光学器件的色差能够用于产生具有不同波长的光的不同焦平面。 In one embodiment, the chromatic aberration from lenses or other optical devices can be used to produce different focal planes having different wavelengths of light. 在可选实施例中,光学部件能够对各个波长设置,并且布置成产生各个颜色的不同焦平面。 In an alternative embodiment, the optical member can be disposed on the respective wavelengths, and arranged to produce different focal planes of respective colors. 图2代表在XY平面上分离的R、G和B焦点。 Figure 2 represents the separation in the XY plane R, G and B focus. 然而,不同的R、G和B焦点能够沿着与XY平面垂直的Z维度布置。 However, the different R, G and B can be arranged to focus the Z dimension perpendicular to the XY plane. 本领域普通技术人员通常理解为:R、G和B焦点能够代表由成像装置200产生的红色、绿色和蓝色光的平面。 Those of ordinary skill in commonly understood as: R, G and B can be the focus for red, green and blue light plane produced by the imaging apparatus 200. 这些不同颜色光的平面能够在物体的表面上扫描,并且反射回到成像装置200中,并且使用检测器208成像。 The flat light of different colors on the surface of the object can be scanned and is reflected back to the image forming apparatus 200, and the imaging detector 208 used.

[0039]如上所述,该系统能够包括独立地或一起产生彩色图像数据和3D形貌数据二者的部件。 [0039] As described above, the system can include separate or together generate color image data and the 3D topography data of both components. 能够使用各种方法执行数据的收集。 It can be performed using various methods of data collection. 例如,系统中的相同或不同的检测器能够用于收集2D和/或3D图像数据。 For example, the system of the same or different detectors 2D and / or 3D image can be used to collect data. 如图2所示,相同检测器208能够用于收集来自多色光源216的反射光和来自光源202的单色光。 2, the identical detector 208 can be used to collect the reflected light from the polychromatic light 216 from the light source 202 is monochromatic. 同样描述了,来自光源202的光束能够分成能够通过成像装置200光学传递的多个光束。 Similarly described, the light beam from the light source 202 can be divided into a plurality of beams of the image forming apparatus 200 through the optical transmission. 在一些实施例中,光束能够分成光束的阵列,该光束的阵列然后能够在将包括对应于光束阵列的焦斑阵列的焦平面中聚焦。 In some embodiments, the beam can be split into an array of beams, and the array of the beam can be focused on the focal plane array includes a beam corresponding to a focal spot of the array. 例如,该阵列能够用于物体的共焦扫描和用于成像物体的表面,以得到表示物体的表面的3D形貌数据。 For example, the array can be used for confocal scanning an object and the imaging surface of the object is used to obtain a 3D representation of the surface topography data of the object. 在一些实施例中,光束的阵列能够结合,使得光束与由多色光源产生的光在空间上重叠。 In some embodiments, the array of beams can be combined so that the beam source and the light generated by the polychromatic spatially overlap at all.

[0040]在一个实施例中,颜色检测器能够用于收集与多色光源相关的彩色图像数据和与单色光束阵列相关的3D形貌数据二者。 [0040] In one embodiment, the color sensor can be used to collect a polychromatic light source associated with the color image data and monochrome array of beams associated both 3D topography data. 例如,颜色检测器(例如,图2中的检测器208)能够具有用于收集颜色和3D形貌数据的期望像素布图。 For example, the color detector (e.g., FIG. 2 of the detector 208) can have a 3D shape for collecting data and color pixel a desired layout. 虽然能够使用任意适当的像素阵列布图,但是在优选实施例中,像素阵列布图具有红色占大多数的像素布置,例如,如图3所示。 Although able to take any appropriate pixel array layout, but in a preferred embodiment, the pixel array layout having a majority pixel arrangement of red, for example, as shown in Figure 3. 当将相应的红色波长用作单色形貌捕捉波长时,图3所示的布置是优选布置。 When the corresponding red wavelength is used as the wavelength capture monochrome appearance, the arrangement shown in FIG. 3 is a preferred arrangement. 相似地,当将相应的蓝色波长用作单色形貌捕捉波长时,图3中的蓝色与红色像素改变位置的蓝色占大多数的布置是优选布置。 Similarly, when the corresponding blue wavelength is used as monochromatic wavelength topography capture, 3 blue and red pixels to change the position of the majority of blue arrangement is preferred arrangement.

[0041]图3提供了特别设计成收集来自在颜色检测器中的预定像素上的共焦阵列的光的示例布图。 [0041] FIG. 3 provides a specially designed to collect light from the confocal detector array on the color of a predetermined pixel sample layout. 例如,其它RGB像素用于收集从成像的物体的表面反射的白光或多色光。 For example, other RGB pixels for collection of the surface of the object imaged white light or polychromatic light reflection. 如图3所示,像素布图具有对不同颜色敏感的像素的重复象限。 As shown in Figure 3, the layout of pixels having different color-sensitive quadrants repeated pixels. 能够将颜色传感器中的像素制造成在左上和右下象限具有红色像素。 The ability to manufacture the color sensor pixels to the upper left and lower right quadrants having red pixels. 右上象限中的像素能够是绿色,并且左下象限中的像素能够是蓝色。 The upper right quadrant of the pixel can be green, and the lower left quadrant of the pixel can be blue. 这些象限能够重复地遍及传感器芯片。 These quadrants can be repeated throughout the sensor chip. 为了更加简单且快速地收集颜色和形貌数据,粗体的红色像素能够与共焦光束的阵列结合,使得各个共焦光束能够定位成照明像素的布图阵列中的各个相应的红色像素。 In order to more easily and quickly collecting topography data and color, bold red pixel array capable of binding co-focus the beam, such that each beam can be positioned in a confocal array layout of an illuminated pixel in each pixel corresponding to red. 如图所示,在系统中能够构成共焦光束的阵列,使得各个光束照明传感器布图中的交替列(例如,列I和3)中的每隔一个的红色像素。 As shown, the system confocal beam array can be configured so that each beam illumination sensor layout in alternating columns (e.g., columns I and 3) the red pixel every second. 因此,当获取3D形貌扫描数据时,像素布图将收集来自粗体像素而不是表面上的其它像素的3D形貌扫描数据。 Therefore, when the scan data to obtain 3D topography, the pixel layout will collect other pixels 3D topography scan data from the bold pixels rather than on the surface. 然而,其余像素以及粗体像素能够用于收集来自反射的多色(例如,白色)光的彩色图像数据。 However, the remaining pixels and pixels that can be used to collect from the bold multicolor reflection (e.g., white) color image data of the light. 如在技术中通常所理解地,能够处理RGB敏感像素并且用于生成物体的表面的彩色图像。 As commonly understood in the art, the handle can be sensitive to RGB pixels and for generating a color image of the surface of the object. 相似地,能够处理表面的3D形貌数据并且用于例如生成表面的3D虚拟模型。 Similarly, capable of processing 3D surface topography data and for generating a surface such as a 3D virtual model. 利用像素的特定布图和已知位置,能够将物体的表面的彩色图像数据和3D形貌数据结合并且重叠在一起以显示给例如用户。 Using the pixel layout of specific and known position, it is possible to color image data of the object and the 3D surface topography data and combined for display to overlap with the user, for example.

[0053]在步骤326中,对于各个位置,结合对应于所选择的焦距的所采用的波长(例如,第一、第二和第三波长)的图像数据。 [0053] In step 326, for each position, corresponding to the selected combination of the focal length of the wavelength used (e.g., the first, second and third wavelength) of the image data. 因此,使用各个所采用的波长的聚焦数据生成结合的图像数据。 Thus, using each of the wavelength used to generate image focus data binding data.

[0054]对于其它图像位置重复步骤322至步骤326。 [0054] For the location of other images, repeat steps 322 to step 326. 因此,对于各个采用的波长,通常使用位置独立的焦距来生成至少具有不平凡的、非平面几何的物体的聚焦彩色图像,从而相对于利用单一或不依赖位置的焦距生成的图像提高图像质量。 Thus, for each wavelength used, typically used to generate position independent focal length of at least a non-trivial, non-plane geometry of the focus color image of the object, and thus with respect to the use of a single focal length or position-dependent image generated improve image quality.

[0067]在许多实施例中,白光用于照明产生聚焦彩色图像的物体,红-绿-蓝(RGB)颜色传感器用于响应于从物体反射的光产生图像信号,并且低色散的光学器件用于将白光的不同波长配置到不同焦平面。 [0067] In many embodiments, the white light for illuminating an object to generate color image focus, red - green - blue (RGB) color sensor responsive to light reflected from the object image signal, and an optical device with low dispersion in the white light of different wavelengths to a different focal plane configuration. 并且在许多目前的优选实施例中,设计光色散、使得红色焦平面与绿色焦平面之间的距离等于绿色焦平面与蓝色焦平面之间的距离。 And many of the presently preferred embodiment, the design of optical dispersion, such that the focal plane from the red and green equal to the distance between the focal plane and the focal plane of the blue green focal plane. 例如,能够将光色散设计成使得:当红色波长焦平面位于参考z维度(Zo)时,绿色波长焦平面位于参考z维度加选择的增量z距离(Zo+△ Z ),并且蓝色波长焦平面位于参考z维度加两倍的选择的增量z距离(Ζο+2Δ Z )。 For example, the dispersion can be designed such that the light: red wavelength when the focal plane is located in the reference z-dimension (Zo of), the green wavelength located in the focal plane of the reference z-dimension selective incremental distance z (Zo + △ Z), and blue wave telephoto located in the reference plane z-dimension plus twice the distance of the selected increment z (Ζο + 2Δ z). 通过在各个阶梯等于选择的彩色图像数据的获取之间的增量z距离(△ Z)的情况下以阶梯方式扫描焦距,能够将三个相邻的彩色图像扫描帧的元素彩色数据(例如,红色数据、绿色数据和蓝色数据)结合以生成特定物体位置的聚焦彩色数据。 By elemental color data at each incremental step distance z equal to the selected color image data acquisition between (△ Z) in the case of scanning the focal length in a stepped manner, it is possible to scan a color image three adjacent frames (e.g., red data, green data, and blue data) combined to generate a specific focus position of the object color data. 图5、6、7和8图示出能够与光学系统连同使用的扫描途径,该光学系统具有设计成使得红色焦平面与绿色焦平面之间的距离等于绿色焦平面与蓝色焦平面之间的距离的色散。 Figure 6, 7 and 8 illustrates the optical system can be used in conjunction with the scanning way, the optical system is designed such that the focal plane difference between the red and green focal plane and the focal plane is equal to blue green focal plane dispersion distance. 虽然图5、6、7和8所示的扫描途径能够与具有设计成使得红色焦平面与绿色焦平面之前的距离等于绿色焦平面与蓝色焦平面之间的距离的色散的光学系统连同使用,但是能够使用任意适当光学系统,包括不具有设计成使得红色焦平面与绿色焦平面之间的距离等于绿色焦平面与蓝色焦平面之间的距离的色散的光学系统。 Although shown in FIG. 6, 7 and 8 having a scanning pathway can be designed such that the difference between the red and green focal plane is equal to the focal plane prior to the dispersion length blue green focal plane and the focal plane of an optical system used in conjunction with , but any suitable optical system can be used, including without having designed such that the difference between the red and green focal plane is equal to the focal plane of the dispersion distance between the focal plane and the blue green focal plane of the optical system. 例如,在这里公开的用于生成聚焦彩色图像的途径能够与具有使得红色焦平面与绿色焦平面之间的距离不等于绿色焦平面与蓝色焦平面之间的距离的色散的光学系统连同使用。 For example, in the way disclosed herein for generating a color image can be focused and the focal plane having a difference between the red and green so that the focal plane is not equal to the dispersion distance between the focal plane and the blue green focal plane of the optical system used in conjunction with . 作为另一个示例,在这里公开的用于生成聚焦彩色图像的途径能够与构造成使得红色焦平面、绿色焦平面和/或蓝色焦平面对于任意特定扫描帧大致一致的光学系统连同使用。 As another example, disclosed herein is used to generate a color image can be focused way and configured so that the focal plane of the red, green focal plane and / or blue for focal plane substantially coincides with any particular frame scanning optical system together with the use.

[0068]图5图示出用于在焦距扫描期间获得聚焦彩色图像数据和表面形貌数据二者的途径。 [0068] Figure 5 illustrates a focal length of the scan period for obtaining the color image data and the way the focusing surface topography data of both. 如图所示,能够在间隔时间内在沿着Z维度在距离上扫描各个波长的焦距。 As shown, capable of scanning along the Z dimension of the focal length of each wavelength over a distance at intervals within. 例如,能够根据物体的表面特征的规模在毫米或厘米或更多的范围内扫描焦距。 For example, it is possible to scan the focal length in millimeters or centimeters or more depending on the size range of the surface features of the object. 图5示出几十到几百毫米(例如,如图所示,大约10至20毫米)的范围内的扫描。 Figure 5 shows the scanning tens to hundreds of millimeters (e.g., as shown, from about 10 to 20 mm) range. 扫描的时间帧还能够是微秒、毫秒或更长等级的。 Time frame is also capable of scanning in microseconds, milliseconds or longer level. 扫描物体的完整扫描时间能够取决于,例如,用于生成图像的Z扫描的区域量和/或数量。 Full scan time of the scanned object can depend on, for example, the amount of area for generating an image of the Z-scan and / or quantity. 在图5至8中,时间轴是毫秒。 In Figure 5-8, the time axis is in milliseconds.

[0069]在许多实施例中,扫描仪收集用于生成成像物体的聚焦彩色图像的数据和/或表示成像物体的3D形貌数据。 [0069] In many embodiments, the scanner to collect data for an object image focused color image data and / or 3D representation of the imaged object topography data. 在图5所示的实施例中,在沿着Z方向的焦距扫描期间,在各个时间点利用多色光(例如,白光)照明扫描的物体。 In the embodiment shown in Figure 5, the focal length in the Z direction during the scanning, at each time point using multi-colored light (e.g., white light) illumination scanned objects. 在图5中,利用B、G和R箱图示出具有白光照明的各个时间点。 In Figure 5, the use of B, G and R boxes illustrating various time points with white lighting. 能够例如通过裁剪扫描仪的光学器件的色差而将来自白光源的蓝色、绿色和红色光的焦距布置在不同的Z位置。 For example, by an optical device capable of cutting the scanner and color from the white light source of blue, green and red light, focal length arranged in different Z positions. 红色、绿色和蓝色光的焦距在扫描期间变化。 Red, green and blue light changes the focal length during scanning. 在扫描期间,能够获取各个焦距的图像数据。 During scanning, the image data can acquire the respective focal length. 一旦获取对于采用的各个颜色波长(例如、红色、绿色和蓝色)的各个图像位置的聚焦图像数据,则能够将各个位置的聚焦颜色数据结合以生成各个图像位置的聚焦颜色数据。 In obtaining the wavelength for each color (e.g., red, green and blue) using the image data of the focus position of each image, it is possible to position the focus of the respective color data to generate a respective combination of the focus position of the image color data. 然后,能够将各个位置的聚焦颜色数据结合以生成物体的整个聚焦彩色图像。 Then, it is possible to focus on the respective positions of color data to generate a combined object focus of the entire color image.

[0070]在采用波长依赖焦距的许多实施例中,例如,由于色差,在不同的时间获得结合以生成特定物体位置的聚焦图像数据的聚焦彩色图像数据(例如,红色、绿色和蓝色聚焦图像数据)。 [0070] In many embodiments, the use of the wavelength dependency of the focal length, e.g., due to the color, the color image data obtained combining the focusing position of an object to generate a particular focus of the image data (e.g., red, green and blue images focused at different times data). 例如,参考图5,当特定物体位置在第一时间点Tl相对于采用的蓝色波长(蓝色焦点位置382)聚焦时,特定物体位置相对于采用的绿色和红色波长(绿色焦点位置384和红色焦点位置386)不聚焦。 For example, referring to FIG. 5, when a particular position of the object at the first time point Tl with respect to the use of the blue wavelength (blue focus position 382) to focus a specific position of the object relative to the use of green and red wavelengths (green focal position 384 and red focus position 386) is out of focus. 在第二时间点T2,特定物体位置相对于采用的绿色波长(绿色焦点位置388)聚焦,而相对于采用的蓝色和红色波长(蓝色焦点位置390和红色焦点位置392)不聚焦。 In the second point in time T2, the position of the object with respect to a particular wavelength of green (the green focus position 388) used in focusing, with respect to the use of the blue and red wavelengths (red and blue focal position of the focal position 390 392) is out of focus. 在第三时间点T3,特定物体位置相对于采用的红色波长(红色焦点位置394)聚焦,而相对于采用的蓝色和绿色波长(蓝色焦点位置396和绿色焦点位置398)不聚焦。 In the third point in time T3, the specific position of the object relative to the red wavelength (red focal position 394) using the focus, and with respect to the use of blue and green wavelengths (blue and green focal position of the focal position 396 398) focus. 在这样的情况下,第一时间点Tl(蓝色焦点位置382)的特定物体位置的蓝色图像数据能够与第二时间点T2(绿色焦点位置)的特定物体位置的绿色图像数据和第三时间点T3(红色焦点位置394)的特定物体位置的红色图像数据结合,以生成特定物体位置的聚焦彩色图像数据。 Green image data in such a case, the blue image data of the first point in time of Tl (blue focus position 382) of the position of the object can be specified with the second point in time T2 (green focus position) and the third specific position of the object the red image data of the time point T3 (red focus position 394) a specific position of the object combined to generate a specific focus position of the object color image data. 例如,能够使用在这里进一步描述的计算机系统和处理器来执行图像数据的结合。 For example, the processor can be used in computer systems and is further described herein to perform combined image data.

[0071]以相似的方式,与扫描仪相距显著不同距离的不同物体位置将具有不同的聚焦焦距。 [0071] In a similar manner, the scanner and the object distance significantly different from different positions of the focus will have different focal lengths. 因此,在焦距扫描期间,将在不同时间点获得这样的不同位置的聚焦颜色数据。 Therefore, the focal length of the scanning period, the focus of such color data obtained in different positions at different time points.

[0072]如图5所示,在得到聚焦彩色图像数据的时间点之间的时间点,能够在焦距扫描期间获得物体的3D形貌数据。 [0072] As shown in Figure 5, obtained at the time point the focusing point in time between the color image data can be obtained 3D shape data of the object during scanning focal distance. 例如,在图5中的时间点I与时间点II之间,能够通过利用以均聚焦于焦距的单独光束的阵列形式的单色光照明物体而得到3D形貌数据。 For example, the time point I in FIG. 5 between time points and II, can be obtained through the use of 3D topography data in the form of an array of separate light beams are focused on the focal length of the monochromatic light illuminating the object. 在许多实施例中,通过多个不同焦距递增地扫描单独单色光束的焦距,并且获得各个焦距的各个光束的图像数据。 In many embodiments, the focal length of the scanning single beam of monochromatic light by a plurality of incrementally different focal lengths, and obtains the image data of the respective light beams at each of focal. 能够在时间点II与时间点III之间、时间点III与时间点IV之间获得相似的3D形貌。 Movable between time points II and a time point III, to obtain similar 3D topography between time points III and a time point IV. 然后,能够分析各个光束的图像数据,以识别哪个焦距产生来自物体表面的各个光束的反射的最大强度,从而表示各个光束相对于物体表面的最佳焦点位置,这表示扫描仪与反射各个光束的物体位置的物体表面之间的距离。 Then, the image data of the respective beams can be analyzed to identify which of the focal length of the maximum intensity of reflection from the surface of each of the light beam, thereby indicating the respective beam with respect to the surface of best focus position, which means that the scanner and the respective reflected light beams the distance between the surface of the object position.

[0073]在扫描物体表面期间,能够在适当时间点收集彩色图像数据。 [0073] During scanning the object surface, color image data can be collected at appropriate time points. 例如,能够通过上下扫描二者以及通过整体或部分地通过扫描收集3D形貌数据。 For example, data can be collected by scanning through the 3D topography of both as well as through the vertical scan whole or in part. 图6例如示出在物体扫描期间收集彩色2D图像数据与3D形貌数据二者的结合方法。 Figure 6 shows an example of image data collected color 2D and 3D topography data combination of the two methods in the object during scanning. 如图所示,能够在沿着Z维度焦距扫描期间的时间点生成彩色RGB图像数据。 As illustrated, the RGB color image data can be generated at a time point along the Z dimension of the focal length of the scanning period. 例如,能够通过结合扫描中的不同时间点的彩色图像数据生成特定物体位置的聚焦彩色数据,其中,各个颜色,例如,RGB在它们各自的时间相对于特定物体聚焦。 For example, it is possible to generate a focus position of the object color data for a particular combination of scanning at different time points of the color image data, wherein each color, e.g., RGB in time relative to their respective focus on a particular object. 如图6所示,能够在焦距扫描过程的上下二者期间收集3D形貌数据和彩色图像数据。 6, the 3D topography can collect data and color image data in both up and down during the focal length of the scanning process. 作为另一个示例,如图7所示,能够在上扫描和下扫描收集彩色图像数据,并且仅在上扫描期间收集3D形貌数据。 As another example, as shown in Figure 7, the color image data can be collected in the scanning and scan, and only during the scanning 3D topography data was collected.

[0074]如上所述,系统能够包括用于3D共焦成像和3D彩色成像的成像光学器件二者。 [0074] As described above, the system can include both 3D imaging optics for confocal 3D imaging and color imaging. 图6描绘了能够包含物体的彩色和3D形貌数据二者的错列收集和/或产生的示例扫描协议。 Figure 6 depicts the object can contain color and 3D topography data collected both staggered and / or exemplary scanning protocol produced. 如图所示,能够收集彩色图像数据(例如,RGB数据),然后收集物体的表面的3D形貌数据,然后彩色图像数据(例如,RGB数据)等。 As shown, the color image data can be collected (e.g., RGB data), and data collected 3D surface topography of the object, and then the color image data (e.g., RGB data) and the like. 能够采用收集彩色图像数据和/或3D彩色图像数据的任意结合。 Any color image can be employed to collect data and / or 3D color image data is available. 例如,能够在适当时间期间收集3D形貌数据,并且用于生成物体的3D虚拟模型,并且在除了用于收集3D形貌数据之外的适当时间期间收集2D彩色图像数据。 For example, it is possible to collect the appropriate time during a 3D topography data, and for generating a 3D virtual model of the object, and except during 3D topography is used to collect data at an appropriate time to collect 2D color image data. 用于收集3D形貌数据的扫描时间能够显著地比用于收集2D彩色图像数据的时间长,例如,5倍、10倍或20倍以上。 3D topography data was collected for the scan time can be significantly more than for collecting 2D color image data for a long time, e.g., 5-fold, 10-fold or more than 20 times. 能够使用较长倍数、较短倍数或任意倍数。 Longer be able to use multiple, multiple or any multiple shorter.

[0075]如图8所示,能够在上扫描期间进行3D形貌数据的收集,并且在下扫描期间收集2D彩色图像数据。 [0075] shown in Figure 8, can be collected during the scanning of the 3D shape data, and the data collected during the next 2D color image scanning. 如图所示,能够独立地收集2D彩色图像数据和3D形貌数据。 As shown, the color can be independently collect 2D image data and 3D topography data. 在焦距扫描过程期间,还设想能够在任意时间使用在这里描述的任意实施例,例如,在图5至8中的实施例以及其它组合。 During the focal length of the scanning process, it can be used also envisaged in any of the embodiments described herein at any time, for example, in FIG. 5-8 and other embodiments in combination. 例如,焦距扫描过程期间的一些上下扫描能够包括2D彩色图像数据和3D形貌数据的收集二者。 For example, some of the focal length of the vertical scanning period of the scanning process can include collecting both 2D and 3D color image data of the topography data. 一些扫描可以包括独立地收集2D彩色图像数据和3D形貌数据。 Some scanning may include separate collection of 2D color image data and the 3D topography data.
