A view planning method for automatic 3D modeling based on the trend surface and limit region

In this paper, a new view planning algorithm of generating 3-D models automatically is presented. It is realized based on the trend surface of the visual field and limit visual region of the vision system. The candidate next best view (NBV) position is obtained by computing the unknown space area according to the trend surface of the acquired the object surface information and limit region of the vision system between viewing points. The final NBV position, which acquired maximum the unknown space area, is got by comparing the above candidate view position.
