DSP-Based Real-Time Inspection System for Strip Surface Defects

HAN Ying-li,YAN Yun-hui,LI Jun,SU Wei-xing(School of Mechanical Engineering & Automation,Northeastern University,Shenyang 110004,China.)  
Taking account of both software and hardware,the effective real-time high-speed inspection as an on-line problem to solve was investigated.The recognition process of strip surface defect images restricting the real-time aspect was separated,then it was processed specially by a DSP chip,and simultaneously recognized by a secondary classifier of support vector machine that combines the recognition rate with accuracy.By such an inspection system,the correct recognition ratio of defect images comes up to 98% with time controlled lower than 10ms.It was proved theoretically and experimentally that the advanced TMS320C6416 DSP image processing platform thus developed can meet well the actual requirement of on-line inspection for strip surface defects in both speed and accuracy.
