近幾年來,智慧型運輸系統 (Intelligent Transportation System, ITS) 正快速地發展,而先進駕駛輔助系統 (Advanced Driver Assistance Systems) 能夠在駕駛環境中適時警告駕駛者其潛在危險性,更是其中最重要的一環。在國外已有 VOLVO 與 Mercedes-Benz,而國內則有裕隆汽車等大廠投入影像式感測器於行車安全的研究,顯示出影像式系統在行車安全之應用尉為主流。
本論文提出一基於立體視覺影像分析之先進汽車駕駛安全輔助技術。其主要的設計精神係透過立體視差計算、U-V 視差分析以及全局運動估計等技術發展出『疑似障礙物特徵偵測模組』、『三維空間偵測模組』、『疑似障礙物行為推論模組』、『安全警示模組』,並將這些模組整合出先進汽車駕駛安全輔助系統。
根據 C 語言的模擬實驗結果顯示,本論文提出的基於立體視覺影像分析之先進汽車駕駛安全輔助技術在測試的九組影像序列中平均F-measure 為 84.9 %,且能夠在具潛在危險性的場景中適時對駕駛人提出警示。
