Claim One:
1. A method for free-view relighting of a dynamic scene based on photometric stereo, comprising the following steps of: (1) performing multi-view dynamic videos capturing 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 based on the captured multi-view dynamic videos; (3) obtaining a static relighted three-dimensional model of the object based on the obtained three-dimensional shape model and surface reflectance peculiarities thereof, and obtaining a three-dimensional trajectory of the object based on the three-dimensional shape model, the surface reflectance peculiarities and the multi-view dynamic videos; (4) obtaining a dynamic relighted three-dimensional model based on the static relighted three-dimensional model and the three-dimensional trajectory of the object; and (5) performing a free-view dependent rendering to the dynamic relighted three-dimensional model of the object, whereby a free-view relighting of the object is achieved.
