Paper Abstract

This paper presents a new robotic vision system based on the Time of Flight technique. It provides the range information at pixel level and a scanning function to acquire the image. The system consists of an internally modulated laser as the source, an image dissector camera tube with pixel resolution, a phase measuring unit and a host PC with associated interface boards. The laser source provides a maximum power of 10 mW at 670 nm wavelength ((lambda) ). A modulation frequency in the MHz region has been used. The range information was obtained by measuring the phase difference between the transmitted and the received signals, using a high frequency phasemeter circuit. The robotic vision system has been tested in various experimental set- ups. It has been successfully used to obtain range images of a variety of scenes. From the results, it is concluded that the robotic vision system has the potential for a wide range of applications.
