摘　　要：在现代测量和检测领域,图像采集卡作为获取信息的重要手段和基础器件,是图像法测量和图像信息获取系统中的关键技术单元之一。针对高速图像采集时存在的模数转换速率高、数据量大、运算复杂等问题,采用了现场可编程门阵列器件(FieldProgrammableGateArray,FPGA)和数字信号处理器(DigitalSignalProcessor,DSP),实现了图像的高速采集和处理。In the fields of modern measurement and detection, image acquisition board, as the important means and basic apparatus to obtain image information, becomes one of the key technology units in the system of measurement based on image method and image information capture. Aiming at the problems existing in high-speed image acquistion, i.e., high speed rate of analog to digital conversion, large amount of data and complicated arithmetic, ect., FPGA (Field Programmable Gate Array) and DSP (Digital Signal Processor) are adopted to realize high speed acquisition and processing of images.
