Design of a real-time motion target detection system based on FPGA

Abstract： Target detection is an important research content in the field of intelligent security. To meet the requirements of miniaturization and high real-time usage, a kind of real-time detection system is designed based on FPGA. The CMOS camera is used to collect video image. DDR3 SDRAM is taken as the cache medium of video image. Combined with the parallel processing characteristics of FPGA devices, the pipeline technology is used to modularize the inter-frame difference detection algorithm. The detection results are transmitted through Ethernet, which realizes image acquisition and motion object detection and display. Experimental test results show that the proposed system can detect moving targets quickly and accurately, with high stability and good real-time performance.
