Abstract: 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.

Abstract: Image data and 3-D spatial data are acquired for an object or scene. Non-unique (over-sampled) image data exist for at least one point on the object or in the scene. A selection mechanism is established for choosing one datum or set of data over another where over-sampled image data exist. The desired image data are isolated or blended to produce a single datum or set of data to represent the image of 3-D spatial data.

Abstract: A system for capturing a virtual model of a site includes a range scanner for scanning the site to generate range data indicating distances from the range scanner to real-world objects. The system also includes a global positioning system (GPS) receiver coupled to the range scanner for acquiring GPS data for the range scanner at a scanning location. In addition, the system includes a communication interface for outputting a virtual model comprising the range data and the GPS data.
