Moving target detection is an important part of intelligent security system. In order to meet the needs of long-distance surveillance and real-time video transmission, a moving target remote monitoring system based on FPGA platform is designed. The system takes Xilinx 's Artix7 series FPGA chip as the core, realizes the video image acquisition through the OV5640 camera, grays the collected image, and buffers the processed image through the DDR3 memory. The frame difference method moving target detection technology is used to detect and mark multiple moving objects, and the detection results are transmitted to the host computer through the Ethernet UDP protocol for real-time display ; the experimental results show that when the image resolution is 640 * 480, the Ethernet UDP transmission speed is 133 Mbit / s, and the video image frame rate is 26 fps, which is larger than the human eye 's visual frame rate of 24 fps, meeting the real-time requirements of video transmission. At the same time, the system can detect and track multiple moving targets remotely and efficiently. Compared with other systems, it has the characteristics of remote real-time detection, miniaturization and low power consumption, and can be further applied to intelligent security systems.
