Abstract
The addition of vision or three-dimensional imagery to a robot significantly enhances its capabilities to perform not only well-defined tasks, but new tasks as well -- tasks that could not be done by a "blind" robot. At the next level, the robot would have a capability of acquiring, processing and analyzing a three-dimensional image of a "real" scene. This paper presents several alternate ways that such three-dimensional imagery can be acquired and represented. Some emphasis will be placed on one approach -- the use of laser radar to obtain range data. However, the primary objective in this paper is to identify and discuss the major problems associated with the acquisition and effective use of this type of imagery, especially in robot vision applications.© (1984) COPYRIGHT SPIE--The International Society for Optical Engineering.
