摘要
于对视频图像检测与识别的需要,提出了一种基于FPGA的视频边缘检测系统设计方案,并完成系统的硬件设计。通过FPGA控制摄像头进行视频采集,双端口SDRAM对图像数据进行缓存,FPGA再对数据进行实时处理。实际采用DE2-115开发板和CMOS摄像头OV7670为硬件平台进行验证。结果表明,该系统具有实时性高,检测准确的特点,达到了设计要求。
Based on the requirement of the video image detection and identification,the design of the video edge detection system based on FPGA is proposed in this paper.Camera is controlled by FPGA for video capture,dual-port SDRAM cache image data,FPGA complete the real-time data processing.Actual use DE2-115 development board and CMOS camera OV7670 as the hardware platform for verification.The experiment and application show that this system has good performance,and achieve the design requirement.
