Method and system for free-view relighting of dynamic scene based on photometric stereo
A method and a related system of free-view relighting for a dynamic scene based on photometric stereo, the method including the steps of: 1) performing multi-view dynamic videos of an object using a multi-view camera array under a predetermined controllable varying illumination; 2) obtaining a three-dimensional shape model and surface reflectance peculiarities of the object; 3) obtaining a static relighted three-dimensional model of the object and a three-dimensional trajectory of the object; 4) obtaining a dynamic relighted three-dimensional model; and 5) performing a free-view dependent rendering to the dynamic relighted three-dimensional model of the object.
