Automatic Relighting of Overlapping Textures of a 3D Model
This paper presents a new method to correct overlapping textures of a single 3D model where each texture was obtained under possibly different lighting conditions and color response of the camera. This situation arises frequently when a single object is digitized using multiple 3D scanners. Our goal is to remove any visible seam and improve color consistency between the textures in order to merge them afterward. To achieve this, we propose an ef?cient algorithm to compute the "ratio lighting" of two textures, derive a common lighting from it, and use it to "relight" each texture. We illustrate our method by correcting textures of human faces acquired with several structured-light 3D scanners. Experimental results are realistic and demonstrate how this method can reduce the need to calibrate colors or explicitly solve for the illumination.
