| Abstract: | It is very important for detecting surface detects during production process.An on-local detection system for defects on electrodeposit surface of nonmetal workpieces was introduced.It is developed on the basis of combination computer technology,image processing and automatic measurement and control technology.CCD photoelectricity detection system is employed in this system with diffused light as illumination apparatus.Through image processing and automatic control by computer,workpieces with defects are automatically selected by selection machine.This system can deal with the difficulty of image processing and detection aroused by strong reflection of electrodeposit surface and meet the demand of practice manufacture. |
