摘要
针对视频图像处理技术对于实时性的要求越来越高,提出了一种以FPGA芯片为核心处理器,融合帧间差分和边缘检测的高清视频目标快速检测方法。系统采用模块化的流水线设计思想,充分利用FPGA的并行机制以及高速处理数据的特点,结合片外SDRAM的高速大容量缓存,实现了对分辨率为1080 p的视频目标图像的采集、缓存、检测以及显示功能。实践检测结果表明,该目标检测系统能够有效实现高清运动目标的检测,并且视频帧率能达到接近30 fps,实时性较好。
Aiming at the increasingly high real-time requirements of image processing technology,this paper proposes a real-time high-definition video target detection method that uses FPGA chips as the core processor and combines inter-frame difference and edge detection.Adopt modular pipeline design ideas,make full use of the parallel mechanism of FPGA and the characteristics of high-speed processing data,combined with the high-speed large-capacity cache of off-chip SDRAM,the collection,cache,detection and resolution of video target images with 1080 p resolution display function.The practical detection results show that the target detection system can effectively detect high-definition moving targets,and the video frame rate can reach close to 30 fps,and the real-time performance is good.
