Abstract 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. ，F(xiàn)PGA（Field Programmable Gate Array）and DSP（Digital Signal Processor）are adopted to realize high speed acquisition and processing of images.
