A three-dimensional profile detection system based on machine vision

Lu Weixin Yin Liying(State Key Laboratory of Robotics and System,Harbin Instituteof Technology,Harbin 150001,China)  
A set of three-dimensional profile detection system based on machine vision is designed for profile detection of parts on product line.This system mainly consists of a data acquisition module based on CCD(charge coupled device),an embedded data processing module based on FPGA(field programmable gate array),a data transmitting module based on USB(universal serial bus),and an image display module based on OpenGL.The structure of this system is very compact,and it can reach higher resolution for parts moving in high speed on product line.Data processing module can run many arithmetics in it,therefore we can choose better.USB data transmitting interface offers faster data transmitting speed,and allows plugging and pulling device when the computer is powered on,so it avoids disadvantages of PCI(peripheral component interconnection) interface which is based on slot,and needs opening of the chassis.Display module based on VC shows detection result in graphic mode,it is more direct and conveniently realizes intercommunication between people and computer.
