摘要
针对目前数字图像采集处理技术的实时性、大容量、小型化等特点,设计了一种基于FPGA的实时视频图像采集处理电路系统。采用FPGA作为整个系统的控制和图像数据处理中心。DDR2 SDRAM为高速储存模块核心器件,CMOS 7670为视频图像采集器件。并通过Quratus Ⅱ和Modelsim等软件对系统的边缘检测算法、控制过程、各个模块等进行硬件工程设计和仿真,实现了视频图像从采集、存储到处理、显示的整个过程。实验表明,视频图像采集处理的动态画面流畅、清晰、实时性好。
Based on characteristics of instantaneously, large capacity and miniaturization of digital image acquisition and processing technology, a real-time video image acquisition and processing circuit system was designed, FPGA was used as the center of controlling the whole system and the center of processing image data. With DDR2 SDRAM the core component of high speed storage module, and CMOS 7670 the video image acquisition device. Through the Quratus II and Modelsim software for edge detection al- gorithm and the control process, each module of the hardware design and simulation, the realization of the video images from the collection and storage to the treating and display, which shows smooth, clear and real-time.
