View Point Representation For 3-d Scenes
Techniques are described for deriving information, including graphical representations, based on perspectives of a 3D scene by utilizing sensor model representations of location points in the 3D scene. A 2D view point representation of a location point is derived based on the sensor model representation. From this information, a data representation can be determined. The 2D view point representation can be used to determine a second 2D view point representation. Other techniques include using sensor model representations of location points associated with dynamic objects in a 3D scene. These sensor model representations are generated using sensor systems having perspectives external to the location points and are used to determine a 3D model associated with a dynamic object. Data or graphical representations may be determined based on the 3D model. A system for obtaining information based on perspectives of a 3D scene includes a data manager and a renderer.

- 1. A computer-implemented method for generating information based on perspectives of a three-dimensional scene comprising:
obtaining a first two-dimensional view point representation of a first location point in the three-dimensional scene based on a sensor model representation, wherein the sensor model representation is generated using a sensor system having a perspective external to the first location point; and determining, with a processor-based computing device, a data representation from the first two-dimensional view point representation without finding three-dimensional coordinates of the first location point, wherein the determining the data representation includes deriving from the first two-dimensional view point representation a second two-dimensional view point representation from a second perspective external to the first location point; deriving, with the processor-based computing device, a distance measurement value between the first location point and a second location point in the three-dimensional scene; and inserting, with the processor-based computing device, the data representation and the distance measurement value into one of the first and second two-dimensional view point representations.
- 9. A system for generating information based on perspectives of a three-dimensional scene comprising:
an object tracker configured to determine a first two-dimensional view point representation of a first location point in the three-dimensional scene based on a sensor model representation, wherein the sensor model representation is generated using a sensor system having a perspective external to the first location point; a data manager configured to determine a data representation from the first two-dimensional view point representation without finding three-dimensional coordinates of the first location point, wherein the data manager is further configured to derive from the first two-dimensional view point representation a second two-dimensional view point representation, the data manager further configured to derive a distance measurement value between the first location point and a second location point in the three-dimensional scene; and a renderer configured to insert the data representation and the distance measurement value into one of the first and second two-dimensional view point representations.
- 12. A non-transitory computer readable storage medium having a set of instructions executable by a processor stored thereon, wherein executing of the instructions causes the processor to generate information based on perspectives of a three-dimensional scene by:
obtaining a first two-dimensional view point representation of a first location point in the three-dimensional scene based on a sensor model representation, wherein the sensor model representation is generated using a sensor system having a perspective external to the first location point; and determining a data representation from the first two-dimensional view point representation without finding three-dimensional coordinates of the first location point, wherein the determining the data representation includes deriving from the first two-dimensional view point representation a second two-dimensional view point representation from a second perspective external to the first location point; deriving a distance measurement value between the first location point and a second location point in the three-dimensional scene; and inserting the data representation and the distance measurement value into one of the first and second two-dimensional view point representations.
