Recovery of reflectance properties for merging multiple 3D scans

A method to merge multiple scans of a 3D object, which exhibit color variation in the overlapped regions is presented in this paper. Our method attempts to recover the reflectance properties of the object from the color image of each view. Then we use the recovered reflectance properties to produce a more consistent color blending in the overlapped regions. The recovered reflectance properties can also be used to apply different lighting to the acquired 3D model. Our method differs from previous works by allowing the object colors to vary across the surfaces and by allowing each scan to have a different light source position.
