Definitions
- GIS GEOGRAPHIC INFORMATION SYSTEM
- the present invention relates to the field of image processing systems, and, more particularly, to geographic information systems (GIS) and related methods.
- GIS geographic information systems
- mapping programs e.g., Google Earth
- architectural design applications e.g., Pro/E, CATIA
- digital design and modeling tools e.g., Maya, 3D ⁇ tudio Max
- three-dimensional visualization analysis tools e.g., Google Earth
- a 3D object is typically created/edited using only 2D input/output devices such as a monitor or display, mouse, keyboard, and/or joystick. This is usually done in one of two ways.
- the first way is to create or place a 3D object in the scene, which can be a cumbersome multi-step process.
- the object is first created or placed in a two-dimensional plane and then manipulated in the third dimension. While there are multiple points of view often being displayed simultaneously, the process may still be relatively unintuitive to the user.
- objects can be natively placed directly in 3D space, but usually only relative to a pre-existing 3D object which already has a spatial context in the current coordinate system.
- One example of an application which allows objects to be natively placed in a 3D space is the InRealityTM sitemodel viewer from the present Assignee, Harris Corp. InRealityTM also provides a sophisticated interaction within a 3D virtual scene allowing users to easily move through a geospatially accurate virtual environment with the capability of immersion at any location within a scene.
- U.S. Patent No. 5,883,625 to Crawford et al is disclosed in U.S. Patent No. 5,883,625 to Crawford et al .
- This patent is directed to a system and method for automatically arranging objects inside a container of a graphical user interface (GUI) .
- Selectable grid styles are provided for arranging cells into different configurations inside the container.
- the cells may be placed in different grid styles, such as rectangular, rhombus—shaped, or circular.
- identifiers are used for placing objects such as icons or buttons in each cell and ordering the objects for other user applications .
- a geographic information system which may include a display, a GIS database, and a processor. More particularly, the processor may cooperate with the display and the GIS database to display a three-dimensional (3D) geospatial image including a plurality of spaced-apart reference markers therein.
- the reference markers may have different visual characteristics indicative of different relative positions within the 3D geospatial image.
- the processor may also associate with each reference marker selectively displayable position data.
- the different visual characteristics may include different sizes and/or different colors.
- An input device may also be connected to the processor, and the processor may selectively display position data for a given reference marker based upon the input device. For example, in the case of a mouse, the processor may display the position data when a mouse cursor is moved to point at the given reference maker.
- the selectively displayable position data may include selectively displayable latitude, longitude, and height coordinates, for example.
- the input device may also cooperate with the processor to draw a line between a pair of reference markers, and the processor may cooperate with the display to display a distance between the pair of reference markers based upon the line.
- the input device may further cooperate with the processor to select a given reference marker from among the plurality of reference markers.
- the 3D geospatial image may include a ground surface below the given reference marker.
- the processor may cooperate with the display to draw a vertical reference line between the ground surface and the given reference marker upon selection thereof.
- the reference markers may be semi-transparent geometric objects, such as semi-transparent spheres, for example .
- the processor may also cooperate with the display to selectively change the spacing between the reference markers based upon the input device.
- the spacing between at least some of the reference markers may be nonuniform and/or non-linear.
- the input device may be used for selecting reference markers.
- the 3D geospatial image may include at least one polygon, and the processor may determine an orientation of the at least one polygon based upon an order of selection of reference markers associated therewith.
- the processor may selectively display the plurality of reference markers with the 3D geospatial image based upon the input device. For example, if the input device is a keyboard, the processor may display the reference markers when a given key(s) is depressed, and remove the reference markers from the display when the given key(s) is released.
- a three-dimensional (3D) geospatial image display method aspect may include displaying the 3D geospatial image on a display with a plurality of spaced-apart reference markers therein.
- the reference markers may have different visual characteristics indicative of different relative positions within the 3D geospatial image.
- the method may further include associating with each reference marker selectively displayable position data.
- FIG. 1 is a schematic block diagram of an exemplary geographic information system (GIS) in accordance with the invention.
- GIS geographic information system
- FIG. 2 is a sample display of a 3D image with reference markers in accordance with the invention with selectively displayed position data.
- FIG. 3 is a sample display of the 3D image of FIG. 2 displaying a distance between a pair of reference markers and with a different spacing between reference markers.
- FIG. 4 is a sample display of the 3D image of FIG. 2 displaying a vertical reference line from the ground surface in the image to a reference marker, and the associated height.
- FIG. 5 is a sample display of the 3D image of FIG. 2 with an alternative embodiment of the reference markers having different colors to indicate different relative positions within the image .
- FIG. 6 is a sample display of another 3D image including semi-transparent spherical reference markers in accordance with the invention.
- FIG. 7 is a sample display illustrating a 3D geospatial image display method in accordance with the invention .
- a geographic information system (GIS) 20 illustratively includes a display 21, a GIS (or other 3D image) database 22, and a processor 23 (e.g., a computer CPU) .
- input devices such as a mouse 24 and a keyboard 25 are connected to the processor 23 for allowing a user to interact with and manipulate data
- the processor 23 cooperates with the display 21 and the GIS database 22 to display a three- dimensional (3D) geospatial image stored in the GIS database, along with a plurality of spaced-apart reference markers 30a- 301 therein.
- the 3D image is simply a ground (e.g., terrain) surface or grid so that the reference markers 30a-301 are more easily identifiable.
- the reference markers 30a-301 are spheres in these embodiments, but other geometric shapes or markers may also be used.
- the reference markers 30a-301 advantageously have different visual characteristics indicative of different relative positions within the 3D geospatial image to help users more readily distinguish the relative positions of object vertices, boundaries, elevations, etc., within an image.
- the different visual characteristics of the reference markers 30a-301 are their different relative sizes.
- the reference marker 30a which is in the foreground is larger than the reference marker 301 in the background, which indicates to the user that the reference marker 30a is "closer" with respect to the particular angle at which the user is viewing the 3D image (i.e., closer from the user's vantage point) .
- reference markers 30a' -3Oi' have different colors (illustrated by different grayscale shade) to indicate their relative positions within the image.
- the darker colored reference markers appear in the foreground, and as the markers get farther away from the user's vantage point their color becomes lighter, although other arrangements may also be used.
- both color and size may be used to indicate relative positions within an image, as will be appreciated by those skilled in the art.
- individual reference markers may be colorized based upon elevation from the ground surface 31 (in a geo-referenced context) , or more generally, based upon a distance from a pre-defined point or surface .
- the processor 23 may also advantageously associate with each reference marker selectively displayable position data.
- the processor 24 will associate respective position data with each reference marker 30a-301 based upon its position within the image, as will be appreciated by those skilled in the art.
- the position data may be referenced to a particular object in a scene based upon a scale, etc., as will be appreciated by those skilled in the art.
- the processor 23 may cause the display 21 to display the position data associated with a given reference marker 30 when the user selects the given reference marker.
- the user has selected the reference marker 30a by moving a mouse cursor 32 to point thereto, which causes the processor to generate a pop-up window 33 displaying the latitude, longitude, and height/elevation coordinates associated with this particular reference marker.
- selection could be performed by pressing a given mouse button or keyboard key, for example.
- the given reference marker' s current coordinates may be displayed and updated in real time as the density of the reference markers is changed, if desired, as will be discussed further below.
- the mouse 24 may also be used to draw a line 34 between a pair of reference markers 30a and 3Og, as seen in FIG. 3. This may done by simply selecting a first reference marker (here the reference marker 30a) , such as by clicking a mouse button when the mouse pointer 32 is pointing thereto, and then dragging the line 34 to the second reference marker 3Og and releasing the mouse button. Of course, other approaches for selecting and/or drawing lines between reference markers may also be used, as will be appreciated by those skilled in the art.
- the processor 23 may also display the pop-up window 33, which in this example displays a distance between the two reference markers (i.e., 2 m). This feature may be particularly beneficial for city planners, etc., who need to determine a distance from one point in a 3D scene (such as the top of one building) to another point (e.g., the top of another building), for example.
- the mouse 24 (or keyboard 25 or other appropriate input devices) may be used to select a given reference marker 30a so that the processor 23 may cause a vertical reference line 35 to be drawn between the ground surface and the given reference marker upon selection thereof, as seen in FIG. 4. That is, the vertical reference line 35 provides a helpful reference for the user to determine where the ground surface 31 directly beneath the given reference marker 30a is located.
- the pop-up window may also be generated on the display 21 by the processor 23 with an indication of the distance between the ground surface 31 and the given reference marker 30a (here, 5 m) .
- the reference markers may be semi-transparent geometric objects, such as semi-transparent spheres 30' ' , for example, as shown in FIG. 6.
- the spheres 30'' in the illustrated example delineate points on an object 40, which could be a building (i.e., a manmade structure), elevated terrain, etc.
- the processor 23 may advantageously display only those portions of the given reference marker outside of the object, as shown, to further help the user appreciate the relative position and boundaries of the object while not obscuring the object itself.
- the processor 23 may also cause the display 21 to selectively change the spacing between the reference markers 30a-301 based upon one of the input devices.
- the processor 23 may change the spacing (i.e., density) of the reference markers 30a-301 based upon a scroll wheel of the mouse 24, which may be done in combination with pressing a particular key (e.g., CTRL key) on the keyboard 25.
- a particular key e.g., CTRL key
- the user is able to quickly and conveniently change the spacing of the reference markers 30a-301 to suit the particular image or zoom level that the user is working with.
- the reference marker density may also be automatically updated as the user changes zoom-level, if desired.
- the processor 23 may also selectively display the reference markers 30a-301 with the 3D geospatial image, i.e., only display them when requested by the user. For example, this may be done based upon one of the input devices such as the keyboard 25. More particularly, a specific key(s) on the keyboard 25 may be assigned for causing the processor 23 to display the reference markers 30a-301 when pressed or held down by the user (e.g., the space bar), and then "hide" the reference markers when the user releases the designated key(s) .
- the method illustratively includes displaying a 3D geospatial image on the display 21 with a plurality of spaced-apart reference markers 30a-301, at Block 72.
- the reference markers 30a-301 preferably have different visual characteristics indicative of different relative .positions within the 3D geospatial image (e.g., size, color, etc. ) .
- the method may further include associating with each reference marker selectively displayable position data, at Block 74, as discussed further above.
- the processor 23 then cooperates with the mouse 24 and/or keyboard 25 to determine when a given reference marker 30 is selected, at Block 76. When this occurs, the processor 23 then performs the appropriate action, such as displaying the respective position data associated with the given reference marker 30, as noted above, at Block 78, thus concluding the illustrated method (Block 80) .
- the reference markers 30a-301 may be expanded to span an entire viewable scene (i.e., view frustum), or just portions thereof in different situations or ' implementations . Moreover, the reference markers 30a-301 may also advantageously be used to place pre-defined objects in the 3D scene, or to define entirely new objects by successively selecting markers, for example. Preferably the grid or matrix of reference markers 30a-301 will have a regular spacing by default. However, additional user or context-definable parameters may be used to automatically increase the sphere density in certain areas causing the dynamic increasing and decreasing of the grid density to be non-uniform or even non- linear throughout the extent of the grid, as will be appreciated by those skilled in the art.
- the keyboard 25 spacebar brings in (i.e., overlays) the matrix of reference markers 30a-301
- the dynamic grid density adjustment does not necessarily .need to be uniform or linear across entire matrix/grid, as noted above.
- the mouse pointer 32 mouse moves over a selectable reference sphere, (a) if there is a ground surface portion below the sphere, a straight vertical reference line 35 is automatically drawn to the ground 31 to show exactly over what ground point that sphere lies, and (b) if the scene is- within a GIS context (i.e., has an origin), the latitude/longitude/height coordinates of the given sphere are shown preferably even if no ground exists below.
- the spheres may be colorized based upon height/elevation or distance from a certain point (showing appropriate color bar legend on the side of the scene) .
- clicking on a given sphere may select it and optionally close out a polygon (or volprint, as discussed in U.S.
- Patent No. 6,915,310 to Gutierrez et al . which is assigned to the present Assignee and is hereby incorporated herein by reference in its entirety) if more than one sphere is selected. In a degenerate polygon case, two selected spheres make a line, as will be appreciated by those skilled in the art.
- the above-described computer system 20 and methods may provide several advantages. For example, they may provide full 3D context relatively fast and with few operations required by a user, as well as providing a GIS (latitude/longitude/height) context for any 3D point in a scene. Furthermore, radial colorization may be provided based upon a distance from a point or object, or planar colorization based upon a distance from surface (e.g., ground) . Other advantages may include dynamic density calibration, as well as non-uniformity in dynamic density calibration (i.e., areas of interest can be adjusted to have a higher density than the rest of the matrix). Moreover, polygon orientation (i.e., winding, in computer graphic terms, which is used to determine if a polygon is front-facing or back-facing) may optionally be automatically deduced from the order that the user selects the spheres .
- GIS latitude/longitude/height
