本論文主要研究有關於移動平台上以彩色雙眼相機偵測移動物,利用SIFT角點擷取器找尋左右影像中所具有的特徵點並結合視差、控制點、色彩分割技術以及極線幾何原理求取左右影像中額外的對應點,再結合雙影像可求取深度資訊搭配行車資訊並利用搜尋視窗概念找出前後影像對應點,最後利用轉移函數與背景消去法求得移動物所在位置。
不同於以往文獻利用至多三個轉移函數補償整張影像,本研究利用色彩分割區塊分別補償以提高轉換的準確率,同時影像中最難處理的大面積平滑區塊,本研究利用角點擷取器與視差概念成功解決特徵點不足的情況。並選擇最佳的轉移函數以完成轉換。
本研究以不同場景驗證演算法的適用程度,成功在景深變化劇烈的室內與戶外環境中找出移動物體,並於戶外成功偵測出具有雙人移動物。
