車(che)(che)牌(pai)識別(bie)攝(she)(she)像機通(tong)(tong)(tong)過光(guang)抑制屏(ping)蔽，電子快門調節(jie)，寬動態功能等(deng)來實現抓拍車(che)(che)牌(pai)：強(qiang)(qiang)光(guang)屏(ping)蔽：在低照度彩(cai)色攝(she)(she)像機的基礎(chu)上，通(tong)(tong)(tong)過軟件(jian)的功能，把(ba)圖(tu)像中亮的部(bu)分(fen)(fen)(fen)遮(zhe)擋(dang)。在交通(tong)(tong)(tong)監(jian)控中，一(yi)般可(ke)(ke)將(jiang)大燈的強(qiang)(qiang)光(guang)遮(zhe)擋(dang)，從而將(jiang)車(che)(che)牌(pai)較清晰的抓拍下來。但是(shi)這款攝(she)(she)像機的缺點(dian)就是(shi)軟件(jian)分(fen)(fen)(fen)辨(bian)不清，對(dui)于圖(tu)像亮部(bu)分(fen)(fen)(fen)界定不清，有可(ke)(ke)能將(jiang)車(che)(che)牌(pai)號碼也遮(zhe)擋(dang)，馬鞍(an)山車(che)(che)牌(pai)識別(bie)系統，同(tong)時無法(fa)處理高速運動物體的抓拍。目前國產(chan)攝(she)(she)像機在強(qiang)(qiang)光(guang)屏(ping)蔽方面做(zuo)的比較多，效果各方反映(ying)不一(yi)。
