工业现场的视频采集系统设计及其实现

Design and Implementation of Video Acquisition System for Industrial Work Field

分析了现有视频采集系统的构成及其缺点,在此基础上设计了一套基于FPGA和USB技术的新系统。FPGA在系统中充当核心控制器,以实现视频采集和视频存储的协调功能,从而大大缩短了设计周期和设计难度,给出了设计思路和原理以及波形仿真图。

Based on the analysis of advantage and disadvantage of different video acquisition systems, a new design of video acquisition system based on FPGA & USB is introduced. The system acts as an interface between CCD camera and a PC. In the system the FPGA acts as the key component that coordinates the video acquisition and storing, which makes the design cycle shorter and reliability higher. The composition and function of the system is described. Complete function simulation of the system and waveform of function simulation are given.
