基于FPGA的视频图像目标检测系统

摘要

In this paper, a moving object detection system based on FPGA is designed. It uses the modular design mode and pipeline processing method, and makes full use of the FPGA features of high-speed parallel processing and DDR2 SDRAM large capacity characteristics. The system uses the combined methods of the background difference method with single Gauss background modeling and frame difference algorithm to achieve the detection of moving objects. Practical test results show that the target detection system can effectively achieve the detection of moving objects and meet the needs of real-time, and has good performance.%设计了一种基于FPGA的运动目标的检测系统,采用模块化设计和流水线的处理方式,充分利用了FPGA高速并行处理特点以及DDR2 SDRAM大容量特性.系统采用了单高斯背景建模的背景差分法同时结合帧间差分法的方式实现对运动目标的检测.实践测试结果表明,该目标检测系统能够有效的实现运动目标的检测,且检测效果良好,满足实时性需求.
