Abstract: By application of the four pieces DSP+FPGA architecture and processing the collected video digital images by the field programmable gate array(FPGA),the automatic fabric inspection is realized.It designs the four pieces TM320C62x as digital image processing core and the connecting of the fabric inspection system control is executed by FPGA.It also designs the classified identification arithmetic of fabric defects based on attributed relational histogram and support vector machine.The experiments show when the velocity of sample fabric is of 100(m/s) and 120(m/s),the automatic fabric inspection system has achieved the accuracy of fabric defect detection 80% and 60% respectively.
