摘要
设计实现一种基于FPGA的视频采集显示系统,包括视频图像的采集、处理与显示3个部分。视频图像部分采用CCD摄像头OV7670作为视频数据的采集,利用在FPGA中构建FIFO并配合SDRAM高速读写实现视频图像数据的高速缓存处理,使用FPGA中构建的Nios Ⅱ嵌入式内核,实现对SDRAM的控制以及视频数据的TFT液晶实时显示。整个系统获得了较好图像采集、显示效果。
A FPGA-based video acquisition and display system is designed and implemented, including video image acquisition, processing and display. A CCD camera OV7670 is used for video data acquisition, and FIFO is constructed combined with the SDRAM high speed read to realize the processing of video image data in the FPGA. The FPGA NiosⅡ embedded kernel is utilized for SDRAM control and real time TFT LCD video data display. The whole system is good in image acquisition and display performance.
