A 2D Vision System with Real Time Recognition Ability

In this paper the architecture and software design of 2D computer vision system are introduced.The hardware of this system consists of microcomputer IBM PC/XT,real-time image input board and camera.The software consists of chain code-basedvision system and traveling-code-based vision system.These systems can operate in-dependently.The 2D computer vision systems can input image in real time,represent eachelement by 1 or 0 code,extract characteristic,recognize object,define coordinate and orientation.And these parameters are transmitted to robot in real time.The joint work of the 2D vision system and the Gold-Key educational robot is also discussed.
