This paper describes a system that semi-automatically builds a virtual world for remote operations by constructing 3-D models of a robot's work environment. With a minimum of human interaction, planar and quadric surface representations of objects typically found in man-made facilities are generated from laser rangefinder data. The surface representations(More)
We present a novel stereoscopic mapping system for use in post-nuclear accident operations. First we discuss a radiation shielded sensor array designed t o tolerate extended cumulative dose using 4 shielding. Next, we outline procedures to ensure timely, accurate range estimation using trinocular stereo. Finally, we review the implementation of a system for(More)
