傳統的2D影像僅能顯示一物件之表面形狀及其平面方向之運行情況,而3D影像則多了Z軸座標來描述該物件與觀察者之間的距離,使其所觀測之物件具有一定的立體感。3D形狀重建(Shape Recovery)即是一個能將一物件由2D影像轉換為3D影像描述的方法,因此如何獲得一張準確的深度地圖一直是3D形狀重建的目標,其中對待測影像選取適當的聚焦量測法來建立深度地圖是一個很重要的部分,在過去文獻中也提出了許多方法,其中Sum Modified Laplcian (SML) 是用固定視窗大小作聚焦程度的衡量,若視窗過大,則建立的深度地圖會過度平滑;反之,若視窗過小,則建立的深度地圖受雜訊影響甚大,於是本論文以SML為基礎,提出了一個調適性視窗演算法。經實驗證明此演算法能改善視窗大小的影響因而獲得準確的深度地圖。
