Part of the Acoustical Imaging book series (ACIM, volume 18)


Object 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.
