application of dma in realtime image processing 技術(shù)在實(shí)時(shí)圖像處理中的應(yīng)用
for realtime image and fast data transfer of fully radiometric 16-bit images, you can choose for an ieee-1394 firewire digital output 用于網(wǎng)絡(luò)和或多臺(tái)熱像儀連接使用,可選擇以太網(wǎng)連接。
based on the theory of image processing arithmetic and the complex background of the inner cannon, the paper put up realtime image capturing method and high precision image measuring arithmetic 本文在深入研究了各種圖像處理算法理論的基礎(chǔ)上,提出了針對(duì)具有復(fù)雜背景的火炮內(nèi)膛圖像的實(shí)時(shí)采集方案和特殊圖像的高精度測(cè)量算法。
during my writing this paper, the following work has been done : dicussed the total plan and designation of the high-spped video collection and processing system of the dynamic realtime image-dection sub system; introduced the designation of the hardware and software of the platform; discussed some technical questions of the hardware and given the implement and the suggestions 本文主要完成了以下工作:論述了動(dòng)態(tài)目標(biāo)實(shí)時(shí)圖像檢測(cè)子系統(tǒng)中高速視頻采集處理平臺(tái)的總體規(guī)劃與設(shè)計(jì);介紹了作者完成的高速視頻采集處理平臺(tái)硬件與軟件設(shè)計(jì);探討了硬件系統(tǒng)設(shè)計(jì)的一些技術(shù)難題,并給出了作者的實(shí)現(xiàn)方法與建議。
with the fast development of modern information technology, the information that will be processed increase immensely . the researchs and applications of image processing, above all the realtime image processing is very important for people all over the world . in recent years, the development computer technology has put the achievement of performance in digital image processing, and the low cost of software in digital image processing make software commonly . first, not only the background of the research problem 現(xiàn)代信息技術(shù)的迅猛發(fā)展使得需要處理的信息量急劇增加,圖象處理方面的研究與應(yīng)用,特別是進(jìn)行運(yùn)動(dòng)圖像處理顯得尤其重要,近年來,計(jì)算機(jī)性能的不斷提高將數(shù)字圖像處理軟件化的趨勢(shì)明顯,軟件實(shí)現(xiàn)成本低,對(duì)于一般性能的要求基本滿足,這樣極大的降低了數(shù)字圖像處理系統(tǒng)的開發(fā)成本,提高了系統(tǒng)在使用和升級(jí)上的靈活性。
