DETERMINING A POINT OF INTEREST USING A THREE-DIMENSIONAL MODEL OF A SCENE |
摘要 |
A three-dimensional image is generated using global or local coordinate, 3-D spatial data, and image data gathered from one or more locations relative to a scene. The global or local position of 3-D spatial data points on the image is determined. The position of a point of interest on the three-dimensional image is determined by creating a three-dimensional polygon using adjacent 3-D spatial data points. The global or local position of these points may then be calculated using, for example, a ray tracing algorithm. The global or local position of a point of interest may alternatively be approximated, for example, by interpolating the global or local coordinates of the 3-D spatial data point(s) closest to the point of interest. Furthermore, a distance, bearing, or other measurement between two points of interest may also be calculated. |
