Abstract
A system and method for determining the slope of a ground imaged area. The system includes a camera, a memory, and a processor. The camera generates a first and a second image of an area of ground from an aircraft. The memory stores bi-directional characteristic information for associated materials. The processor determines a material type associated with a plurality of the pixels based on a color value of the pixels. The processor retrieves bi-directional characteristic information from the memory for a pixel based on the determined material type. A slope value at a pixel location is determined based on the associated viewing angle values, a determined radiance change value, and the retrieved bi-directional characteristic information.
