摘要
为了解决图象中因遮挡而引起的不可视区域问题，需要用许多传感器从不同的点去测量景象或物体。本文提出采用计算机来计算传感器应处于的位置和方向，最大限度地观察景物在前几个图象中的不可视部分。在未知景物几何尺寸的条件下，只要分析所给图象的数据即可获得一些待定的方向，从而计算出三维模型的尚未观察到的方格元素的数目，其具有最大数目的方向即为最佳视点的方向。
To resolve the ambiguities caused by occlusion in images,the sensor to measure the scene from several different views is needed.The approach presented in this paper is to compute the observation location and directon for sensor placement,from which the unseen parts of the scene can be observed most by the sensor,when no priori geometrical information about the scene is available.After analyzing the given range image data,some candidate directions are obtained to calculate the number of unseen grid cells of the 3 D model from these candidate directions.The one with the largest number is the next best viewing direction.
