Fr. Schultz,A. G?tte,W. PetersenObject recognition is an important aspect in the development of a robot eye system. The use of television cameras has been investigated, however no particularly effective method has been developed. We are developing a new method based on ultrasonic recognition and report some recent experimental results.作者: 光滑 時(shí)間: 2025-3-22 01:36
