Vision Robotics has developed a 3-D stereo vision SLAM, visual odometry, object identification, and tracking system for autonomous robots. The current applications include an autonomous canister style vacuum cleaner and a sensor system for military UGV's. The presentation will describe the 3-D stereo vision SLAM algorithms including the stereo vision processing, particle based localization, and 3-D map generation. It will conclude with a demonstration of the 3-D stereo vision SLAM sensor system on a prototype Autonomous Mapping Vehicle (AMV) being developed for SPAWAR System Center San Diego. The current prototype uses a Segway RMP-50 as a base platform, has four stereo camera pairs, and maps at over 100 square feet per minute with speeds over 2 mph. An external link via 802.11N to a laptop provides for start/stop/pause control and real-time display of the map and pose data. The AMV will autonomously move throughout an area, and when it has finished exploring the complete area, it will return to the starting location.
