Abstract
A technique of synthesizing a panoramic environment map containing intensity and range information of a scene, which includes estimation of orthographic range from a plurality of pairs of stereo images, transformation of orthographic range estimates to perspective or directional range estimates, transformation of planar intensity and range images to cylindrical images, registration of overlapping cylindrical images, and blending of intensity and range information.
