Pyramidal Normal Map Integration for Real-time Photometric Stereo

Abstract : This paper presents a real-time photometric stereo method designed for online 3D telecommunications. This method requires only consumer grade hardware such as a webcam and a GPU. The lighting conditions are controlled from the computer screen and the photometric reconstruction is performed on the GPU. Our method reaches real-time rendering thanks to a pyramidal integration of the normal maps based on an iterative scheme. Moreover, we propose a method to relax the constraint on the synchronization between the light source controller and the camera.
