Paper Abstract

The system of steel ball surface quality detection based on CCD is designed and operating principle is analyzed in this paper. An in-depth study on illuminating system, detecting environment and image processing is presented. According to reflected light characteristics of steel ball surface, the illuminating project of point light source scattering is presented, which can avoid losing original information. Image processing order, step and concrete algorithm are designed and researched based on image identification technique and corresponding software is designed. Repeatability and precision testing is put forward and the main cause of error is analyzed. The testing results indicate that the detection system can meet the design requirement."
