Abstract :
A novel 3-D vision system using a spatial filter for unmanned carriers such as a mobile robot or an automated vehicle is proposed. The authors present the fundamental principle of the system, its signal processing method, and experimental results. To confirm the applicability of the system, simulation experiments have been carried out showing that obstacles placed at 40 cm and 70 cm can be discriminated. Simultaneous measurements of their ranges, azimuth angles, and sizes were carried out successfully
