[0055] 当所述二维图像驱动信息为2η进制数据时,η≥2,只需将上述高电平分为2η_1份,使得所述LED在非零电压下具有2n-l种不同亮度的显示状态,加上零电压下的不亮状态即可共有2n种显示状态。 [0055] When the two-dimensional image information 2η driver binary data, η≥2, just above high into 2η_1 parts, so that the LED has 2n-l different brightness at zero voltage display state, with no light at the zero-voltage state to a total of 2n kinds of display.

[0056] 本实施中所述二维图像驱动信息为四进制数据,可用于驱动所述LED发光器件具有四种不同的显示状态,相比于二进制数据,降低了成像阵列进行图像显示时编码冗余,提高了信息传递量,同时驱动相对简单易于实现。 [0056] In the present embodiment the two-dimensional image information as quaternary data driver to drive the LED lighting device can be used with four different display state, compared to the binary data, the imaging array reduces image display Coding redundancy, improving the amount of information transmitted, while the drive is relatively simple and easy to implement.

[0057] 如果所述二维图像驱动信息仅为一帧图像,只需控制所述成像阵列对应显示一帧二维图像即可。 [0057] If the two-dimensional image information is only an image-driven, just controlling the imaging array corresponding to display a two-dimensional image can be. 如果所述二维图像驱动信息具有多帧二维图像,则需要以设定的帧变换速度,依次控制所述LED显示多帧二维图像。 If the two-dimensional image information with multi-frame drive two-dimensional image, you need to set the frame rate conversion, followed by controlling the LED display frames of two-dimensional images.

[0058] 所述成像阵列包括设置在所述成像阵列三个顶角的锚点区域,位于所述成像阵列同一边的两个锚点间设置有同步带,所述同步带包括第一显示状态以及第二显示状态; [0058] The imaging array comprises a set of three vertices in the imaging array anchor region, located in the imaging array is provided with a belt between two anchor points with one side of the belt includes a first display state and a second display state;

[0059] 在控制所述成像阵列显示多帧二维图像时,所述锚点显示状态不改变,在相邻的两帧二维图像中,前一帧的二维图像与后一帧的二维图像的同步带的显示状态不相同。 [0059] In controlling the multi-frame imaging array display two-dimensional images, the anchor point does not change the display state, the two adjacent frames of two-dimensional images, two-dimensional image of the previous frame and the rear frame bis dimensional image display state is not the same belt.

[0060] 参考图2,图2为本实施所述LED阵列显示面板的结构示意图,所述LED阵列显示面板为64X64的LED阵列,包括4096个LED发光器件显示器件。 [0060] Referring to Figure 2, Figure 2 is a schematic structural view of the implementation of the LED array display panel, the LED array display panel 64X64 LED arrays, including the 4096 LED devices display. 其三个顶角分别设置有具有3X3个LED发光器件的锚点区域1,锚点区域2,锚点区域3,位于。 Its three vertices are respectively provided with a 3X3 anchor region having an LED light emitting device, the anchor regions 2, 3 anchor region, located. 位于LED阵列同一边的两个锚点间设置有同步带,所述同步带包括:同步带5和同步带4。 LED array located between two anchor points with one side is provided with a belt, the belt comprising: a belt 5 and the belt 4. 每个同步带包括位于同一条直线上的61个LED发光器件。 Each belt includes 61 LED devices located on the same line.

[0061] 通过所述锚点区域可以定位所述LED阵列的显示区域,设置所有锚点区域的在进行图像显示时显示状态不变,对于具有3X3个LED发光器件的锚点区域,设置所述锚点的显示状态为中间的LED发光器件为最亮,位于中间LED发光器件四周的八个ELD发光器件为不売。 [0061] may be positioned through the anchor region of the LED array display area, setting all the anchor when the image display area of the display state change, the anchor region having a 3X3 LED light emitting device, provided the Displays the status of the anchor for the middle of the LED light emitting device is the brightest, situated in the middle surrounded by eight LED devices emitting device is not bai ELD.

[0062] 所述同步带包括第一显示状态以及第二显示状态,通过所述同步带可以确定两帧二维图像是否是相邻的两帧二维图像,在驱动所述LED阵列显示面板进行多帧二维图像显示时,同一帧的二维图像的同步带显示状态相同,相邻的两帧二维图像中同步带显示状态不同。 [0062] The belt includes a first display state and a second display state, the belt can be determined by two-dimensional image if it is adjacent to the two-dimensional image, in driving the LED array display panel When multi-frame two-dimensional image display, two-dimensional image of the same frame timing belt of the same display state, two adjacent two-dimensional image frame display state different belt. 可以设置所述第一显示状态为不亮,所述第二显示状态为最亮。 You can set the first display state is not lit, the second display state is the brightest.

[0063] 对于64X64的成像阵列除去三个锚点区域以及两个同步带,还有3947个LED发光器件可以用于填充所述二维图像驱动信息,即此时所述成像阵列每帧图像有3947个像素点。 [0063] For the imaging array 64X64 removing three regional and two belt anchors, as well as 3947 LED light-emitting devices can be used to fill the two-dimensional image-driven message that this time the imaging array each frame there 3947 pixels.

[0064] 需要说明的是,当采用液晶显示面板作为所述成像阵列时,可通过控制所述液晶显示面板的各个像素单元的显示状态使得依次显示多帧二维图像。 [0064] It should be noted that, when using the liquid crystal display panel as the imaging array, by controlling the display state of each pixel of the liquid crystal display panel unit such that a plurality of frames sequentially displaying two-dimensional images.

[0065] 步骤S3:对所述成像阵列的显示状态进行采样,获取所述二维图像,所述采样的速度大于或等于所述二维图像的帧变换速度的二倍。 [0065] Step S3: the display state of the imaging array is sampled to obtain the two-dimensional image, the sampling rate of greater than or equal to the frame rate of the two-dimensional image transformation twice.

[0066] 控制所述采样的速度大于或等于所述二维图像的帧变换速度,以使得所述成像阵列在显示多帧二维图像时,将成像阵列所有显示的二维图像都采集,避免遗漏成像阵列的显示状态。 [0066] The control of the sampling rate is greater than or equal to the two-dimensional image of a frame rate conversion, so that the imaging array in a two-dimensional image when displaying a plurality of frames, all of the imaging array are collected two-dimensional image display, to avoid It displays the status of the imaging array omissions. 具体的,所述采样速度可以等于所述二维图像的帧变换速度的二倍。 Specifically, the sampling rate may be equal to twice the frame rate conversion of two-dimensional image.

[0067] 步骤S4:对所述二维图像进行解调处理,进而获取所述待发送信息。 [0067] Step S4: the two-dimensional image of the demodulation processing, thereby acquiring the information to be transmitted.

[0068] 由于在获取所述二维图像时,不能完全保证图像采集装置与所述成像阵列正对设置,所以获取的成像阵列的显示图像可能存在几何畸变。 [0068] Since acquiring the two-dimensional image, the image pickup device is not guaranteed and the imaging array is on the setting, the display image acquiring imaging array may exist geometric distortion. 故在进行解调处理之前还包括:对获取的所述二维图像进行几何校正,消除所述二维图像的几何畸变。 Before it also includes a demodulation process: on the two-dimensional image acquisition geometric correction, eliminating the two-dimensional image of geometric distortion. 可采用图像处理领域的数学变化进行所述几何校正,如可以采用HOUGH变换原理进行几何校正。 Mathematics can change the field of image processing performed geometric correction, such as the principle can be used HOUGH transform geometric correction.

[0071] 在采用图像采集装置获取所述成像阵列的显示图像时,势必会将成像阵列周围环境图像一并采集到,即采集的二维图像信息存在环境信息干扰。 [0071] When using an image acquisition device acquires the display image of the imaging array, the array is bound to the surrounding environment will be imaged image acquisition to be two-dimensional image information that is collected there is environmental information interference. 因此,此时首先需要根据所述锚点区域确定每一帧二维图像的有效显示区域。 Therefore, at this time first we need to determine the effective display area of two-dimensional image of each frame according to the anchor region.

[0072] 步骤S42:根据获取的所述二维图像的同步带显示状态去除所述二维图像中的冗余图像,使得采样得到的二维图像与所述成像阵列显示的二维图像一一对应,实现信息同 [0072] Step S42: According to the two-dimensional image acquired belt of the two-dimensional image display state removing redundant image, so that the two-dimensional image and two-dimensional image of the imaging array shown eleven sampled correspondence, information with

止/J/ O Stop / J / O

[0073] 由于所述采样的速度大于所述二维图像的帧变换速度,这样会导致成像阵列的同一帧二维图像被采集多次,因此,此时根据所述同步带的显示状态可以去除被重复采集的二维图像,使得采集的二维图图像与成像阵列显示的多帧二维图像一一对应,实现信息同步。 [0073] Since the sampling rate is greater than the frame rate converting two-dimensional image, this will result in the same frame of the imaging array is two-dimensional image acquisition times, and therefore, can be removed at this time based on the display state of the timing belt dimensional image acquisition is repeated so that the multi-frame two-dimensional image correspond to the two-dimensional images of the imaging array displays collected information to achieve synchronization. 如果采集相邻的二维图像的同步带显示状态相同,即可判定为重复采集的二维图像,仅采用其中一帧图像即可。 If the acquisition of the adjacent two-dimensional image display state of the same belt can be determined that the two-dimensional image acquisition is repeated using only one frame image can be.

[0074] 步骤S43:对信息同步后的二维图像依次进行解调处理,获取所述待发送信息。 [0074] Step S43: two-dimensional image information are sequentially synchronized demodulation processing, to obtain the information to be transmitted.

[0075] 经过信息同步后的二维图像与成像阵列显示的多帧二维图像一一对应,此时进行信息解调处理即可获得所述待发送信息。 [0075] After more than a two-dimensional image frames correspond to the two-dimensional image information synchronized with the imaging array of display, in which case you can get information demodulation processing of the information to be transmitted.
