本文描述了由针图重建深度图的方法.首先由一对强度图象构成针图.为此,利用由图象发射等式和表面平滑条件得到的两种限制构成迭代算法,由遮挡的边界提供边界条件和由几个特殊点给出有用的起始值,从而大大减少迭代次数.然后用所获得伪针图构成深度图。为获得较为理想的表面深度图,使用了迭代弛张方法。 This paper describes a method of reconstructing a depth map from a pin map by first constructing a pin pattern from a pair of intensity images. To this end, two constraints resulting from the image emission equation and surface smoothing conditions form an iterative algorithm consisting of occluded boundaries Providing boundary conditions and giving a useful starting value from several special points greatly reduces the number of iterations, and then uses the resulting hypodermograms to construct a depth map. To get a better surface depth map, an iterative relaxation method was used.
