In view of the wide application of moving object detection technique in the field of national defense,a kind of moving object detection system is designed based on FPGA.Video image with a moving target is collected by using CCD camera,and the sampled video image is transmitted to SAA7113H for decoding.Then decoded digital signal is supplied to the FPGA to realize frame difference algorithm to achieve the purpose of moving target detection,the data is transmitted to a SAA7121H chip to encode,and the encoded video data displays in the display unit.The experimental results show that,the moving target detection system can real-time detect moving targets,and it has high stability and good real-time performance.
