Abstract

The capability of vision is desired in many applications in which a machine interacts with its surrounding environment. Detecting and recognizing 3-dimensional objects in a 3-D environment is an especially challenging task. In this paper we describe a high speed 3-D sensor which produces, at a high rate of speed, a dense range map of an object. The high data rate is obtained by using a triangulation scheme which utilizes a holographic scanner to position the laser beam on the object, a digital angle detector to determine the angle to the laser spot on the object and a pipelined processor to calculate the range to the object. The limits to the resolution of this type of 3-D vision sensor will be discussed.
