Abstract
AbstractIn this paper, we propose an object recognition system which consists of two modules. One is an object extraction module using a low‐resolution range image. The other is a position measurement module for detecting precise position of each object using an intensity edge image. To acquire a range image, we propose stereo vision with random‐dot pattern projection. This method enables reliable stereo matching, even if there is no texture on the objects. The equipment is simple because a variable pattern is not necessary. We found this system has 99.8% recognition reliability and the processing time is approximately 5 s/image, providing satisfactory performance for practical use. © 2002 Wiley Periodicals, Inc.
