Bit size measurement for parts of large plate-shaped hole

Bit size measurement of parts of large plate-shaped hole has been a technical difficulty. It use a visual imaging technology to test the large workpiece size online and detection of the quality of whether The device composite by the console, mechanical transmission, photoelectric detect system, lighting system and computer digital image processing system. The detection principle is controlled CCD photoelectric detection system along the rail for uniform linear motion by the console to measured holes large plate-shaped spaces workpiece size measurement Through digital image processing technology and image mosaic technology to process the image of photoelectric detection system collected Object-image telecentric beam path design, and use the written procedures to detect the shape and position and the results can be real-time display in computer. In order to achieve the non-contact measurement on a large plate-shaped hole bit size workpiece.
