WebTSDF：Truncated Signed Distance Function (截断符号距离函数) 三维重建的定义. 三维重建是指根据单视图或者多视图图像重建原始三维信息的过程。单视图缺少深度、多视角信息，基于单视图的三维重建效果较一般。 Webtion. As reconstruction only requires information close to the actual surface, the TSDF only maps points within a truncation band around the actual surface. In practice, the TSDF is stored as a evenly-spaced grid of voxels and is estimated by linear interpolation between the stored tuples. The directional TSDF [2] dir (p) = (D (p)) D2Directions
