WebPhotometric Stereo Advantages And Disadvantages. 1. ABSTRACT. The essence of an image is a projection from a 3D scene onto a 2D plane, during which the depth information is lost. The 3D point corresponding to a specific image point is constrained to be on the line of sight. From a single image, it is very difficult to determine the depth ... Webphotometric stereo images. So, they transformed the coarse 3D mesh into a parameterised 2D space using a parameter-ization technique that reduces distortions [41]. In this work, with the aim to avoid the mapping proce-dure, we present a differential approach for MVPS. Being inspired by the signed distance function parameterisation usedbyMaieretal.
