An ultrasonic robot eye for object identification using neural network

Abstract

To construct an ultrasonic robot eye, a new system which combines acoustical imaging with a neural network was developed. In this system, by measuring sound pressures of scattered waves by a receiver array, 3-D object categories are identified, their locations estimated, and their images improved. The structure of the system is described, and some experimental results are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
