Application of Embedded Processing System in Surface Defect Detection System for Steel Strip

Due to the plate surface defects image processing system of large amount of calculation,high real-time performance and small volume problem,this paper shows a new solution,introducing the FPGA and DSP processor to image acquisition and pre processing,utilizing the FPGA of powerful parallel computation ability and DSP in multiplication operation superiority,transplanting the original frame by the client/serve system and pretreatment operation into processing board based on DSP and FPGA accomplished.The experimental results show that real-time performance is high,adaptability is good,and the system can satisfy the design requirement.
