基于FPGA高速圖像采集卡的研制

摘要:在現(xiàn)代測量和檢測領(lǐng)域，圖像采集卡作為獲取信息的重要手段和基礎(chǔ)器件，是圖像法測量和圖像信息獲取系統(tǒng)中的關(guān)鍵技術(shù)單元之一。針對高速圖像采集時(shí)存在的模數(shù)轉(zhuǎn)換速率高、數(shù)據(jù)量大、運(yùn)算復(fù)雜等問題，采用了現(xiàn)場可編程門陣列器件（Field ProgrammableGate Array，FPGA）和數(shù)字信號處理器（Digital Signal Processor，DSP），實(shí)現(xiàn)了圖像的高速采集和處理。

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.
