人臉識別應用對圖像傳感器提出更高要求

由于行業的特殊性,安防視頻監控攝像頭的圖像傳感器主要考量三大關鍵點——信噪比、靈敏度和動態范圍。現階段,智能安防監控強調的人臉抓拍、視頻結構化等應用,對“視覺”系統提出了更高的要求。

兩種曝光Shutter技術: Rolling Shutter 和 Global Shutter

 

 

Rolling Shutter:Rolling Shutter的曝光方式是按照逐行的方式來進行曝光,即傳感器在成像時,每行像素逐行依次進行曝光,且每行像素的曝光之間會有一定的時間間隔。

Global Shutter:快三开户注册與Rolling Shutter不同,是整幅畫面同一時間曝光實現。攝像頭中圖像傳感器的所有像素點同一時間感應光線,同時曝光。傳感器讀出的是同一時間的同一畫面。

最匹配AI視覺應用的Global Shutter技術

據了解,Global Shutter圖像傳感器技術最早是應用在工業自動化領域的高端技術,主要為自動化工業生產線檢測系統拍攝高速清晰的圖像,以及為運動的機械手臂提供精準的圖像數據源。隨著AI時代的崛起,越來越多的應用領域需要使用到具備邊緣計算能力的智能感知類產品快三开户注册,思特威敏銳地察覺到了這一應用發展的趨勢,適時地推出了SmartGS系列Global Shutter CIS產品。

“對于人工智能的市場發展趨勢,我們在2015年左右就已經開始預判了,這個行業如果用人工智能做一些革命的話,Global Shutter技術的應用是必然趨勢。但有一點,在工業自動化里面用的Global Shutter實際上現場都有補光,它的環境相對比較穩定,但人工智能場景具有不確定性,環境更為復雜,因此,在Global Shutter的基礎之上,我們還加入了BSI背照式傳感器來提升傳感器的感度。將BSI技術和Global Shutter技術放在一起,可以極大地增強Global Shutter 的場景適用性。快三开户注册”白震東表示。
