38、的越來越多地被應(yīng)用到手機(jī)通信設(shè)備、視頻影像設(shè)備和個(gè)人娛樂設(shè)備中。由于用戶體驗(yàn)的要求越來越高，高清圖像以及更加便攜的設(shè)備是未來圖像視頻采集系統(tǒng)設(shè)計(jì)的趨勢，用戶希望能快速高效的傳輸視頻圖像，目前常用的與主機(jī)通訊的數(shù)據(jù)采集傳輸協(xié)議有P C I 總線、P C IE x p r e s s 總線和U S B 總線，使用P C I ／P C IE x p r e s s 總線的圖像采集系統(tǒng)雖然具有較高的傳輸速率，但是其不支持“熱插拔”功能，比較多的

39、系統(tǒng)還是采用支持“熱插拔”功能的U S B 2 ．0總線作為視頻圖像的傳輸協(xié)議。U S B 2 ．0 總線是一種標(biāo)準(zhǔn)的串行接口總線，可以達(dá)到4 8 0 M b i t ／s 的傳輸速率，但是U S B 2 ．0 標(biāo)準(zhǔn)總線接口也只能傳輸一些標(biāo)清的視頻圖像數(shù)據(jù)，隨著大吞吐量的高清圖像及視頻媒流體的出現(xiàn)，U S B 2 ．0 總線的傳輸速率也很難滿足一些高清視頻圖像采集的應(yīng)用，所以采用超高速的U S B 3 ．0總線技術(shù)來傳輸高清視頻圖像的設(shè)

40、計(jì)能很好的滿足這些應(yīng)用。本課題針對高清視頻圖像采集系統(tǒng)的應(yīng)用以及視頻圖像數(shù)據(jù)傳輸速率要求的不斷提高，研究和設(shè)計(jì)了基于超高速U S B 3 ．0 總線的高清視頻圖像采集系統(tǒng)，設(shè)計(jì)出的系統(tǒng)可以傳輸高清的視頻圖像，同時(shí)傳輸速率可以達(dá)到目前市場上的基于U S B 2 ．0 標(biāo)準(zhǔn)的圖像采集系統(tǒng)的十倍多，可廣泛用于高分辨率的網(wǎng)絡(luò)攝像頭、高速視頻監(jiān)視器、高精度的工業(yè)相機(jī)和醫(yī)療圖像采集顯示等領(lǐng)域。本論文主要討論基于超高速U S B 3 ．0 接口的視頻

41、圖像采集系統(tǒng)的研究和設(shè)計(jì)，首先簡單介紹了視頻圖像采集系統(tǒng)中的圖像傳感器技術(shù)及其發(fā)展趨勢，其次介紹了U S B 3 ．0 接口技術(shù)和圖像采集系統(tǒng)的原理，然后詳細(xì)介紹了整個(gè)系統(tǒng)的軟硬件設(shè)計(jì)、高清圖像的采集和超高速U S B 3 ．0 圖像數(shù)據(jù)的傳輸，通過調(diào)試和驗(yàn)證測試最終的系統(tǒng)產(chǎn)品，最后分析總結(jié)出U S B 3 ．0 接口在高清視頻圖像采集系統(tǒng)中的性能和優(yōu)勢。關(guān)鍵詞：圖像傳感器，U S B 3 ．0 ，視頻采集，高清圖像中圖分類號：T P
