技術說明

一種擴充實境中基於深度攝影機之遮蔽效果優化方法，用於包含深度攝影機及二維攝影機之擴增實境系統中。此方法包含以下步驟：利用深度攝影機拍攝一場景及於場景中的物體而取得初始深度資料，並利用二維攝影機拍攝場景及物體而取得二維影像資料；對初始深度資料進行修補而獲得修補過的深度資料；依據修補過的深度資料與虛擬模型進行深度緩衝運算，以取得物體與虛擬模型的遮蔽關係，而依據二維影像資料及虛擬模型產生被遮蔽區域影像；依據被遮蔽區域影像估算區域近似多邊形；以及依據區域近似多邊形、二維影像資料及虛擬模型產生遮蔽結果。 A method for optimizing occlusion used in an augmented reality system comprising a depth camera and a two-dimensional camera comprises the steps of: capturing, by the depth camera, a scene and an object in the scene to obtain initial depth data, and capturing, by the two-dimensional camera, the scene and the object to obtain two-dimensional image data; inpainting the initial depth data to obtain inpainted depth data; performing a depth buffer calculation according to the inpainted depth data and a virtual model to obtain an occlusion relationship between the object and the virtual model, and generating an occluded partial image according to the two-dimensional image data and the virtual model; estimating a partially approximated polygon according to the occluded partial image; and generating an occluded result according to the partially approximated polygon, the two-dimensional image data and the virtual model.
