摘要
图像采集是视频监控、图像识别、多媒体数据分析等常用图像处理系统的前端基础,而采集灰度图像可以更加便捷地进行后端复杂的图像算法处理。于是设计实现一种基于FPGA的灰度图像采集系统,系统主要采用OV7670图像传感器采集图像数据,并在主控FPGA内部配合SDRAM缓存,经过系统图像预处理,采集得到所需的灰度图像并显示。该系统有性能稳定、成本低、可靠性高等优点,在工业生产、医疗视频等领域具有良好的应用价值。
Image acquisition is the front-end basis of video monitoring,image recognition,multimedia data analysis and other common image processing system,and gray image acquired can be more easily used in the back-end complex image algorithm processing.Then a gray image acquisition system is designed and implemented based on FPGA,the OV7670 image sensor will be mainly used in the system to capture image data,and the FPGA will be taken as the master chip,with the SDRAM as data buffer,through the system image data pretreatment,the desired gray image will be acquired and displayed.The system has the advantages of stable performance,low cost and high reliability,and it has great applicable value in industrial production,medical video and other fields.
