本文主要目的在發展一套以人類視覺系統的形態辨識過程為基礎的漸進式交通標誌辨識系統,當系統接收到車載型攝影機拍攝到的連續影像時,交通標誌偵測模組立即被啟動,以模擬人類透過注意力集中的方式,很快且正確地偵測出影像中交通標誌的所在位置並分辨出它的種類(如紅色禁止標誌、紅色警告標誌等),然後交給辨識模組進行辨識的工作。但是,交通標誌偵測模組偵測出影像中的交通標誌時,此時交通標誌可能因距離車子還很遠,導致影像特徵不足而使交通標誌辨識模組無法做出最正確的辨識。因此,本系統先以僅有的物件特徵對交通標誌做粗略的猜測,同時系統繼續搜集更多的影像特徵,不斷地修正錯誤的猜測,直到辨識出交通標誌的類別為止。實驗結果證實這個辨識方法不但具可行性及擴充性,亦可套用在其它辨識方面的應用。
