Development of a well-structured industrial vision system

A well-structured high-speed industrial vision system that emphasizes modularization of fundamental image processors compatible with the standard VME-bus, software realization of application-dependent algorithms, and a pipelined architecture using extra vision buses has been realized. The hardware modules are a binary image projection processor, a general-purpose image processor using a high-speed digital signal processor, a lookup table/arithmetic processor, and an image histogrammer. The system software is designed as a multilayered structure surrounded by the operating system for effective user interface and easy modification. To show the validity of this vision system, it was applied to an industrial IC mark-checking system, and tested in real-time successfully.<
