Stereo Reconstruction with Intensity Correction of Non-Lambertian Images

Abstract

In the past, the diffuse reflection component has often been assumed to be Lambertian in many studies of photometric and multi-view stereo, which aim to extract 3D information from images. We propose a method to correct intensities of non-Lambertian images for directly using the existing stereo reconstruction methods. Our method obtains Lambertian images by estimating the incident angles relative to the surface normals from a single image.
