Abstract
This contribution describes an automatic method to retrieve the diffuse radiometric surface model of moving persons or other objects along with the object geometry using a multi-camera system. The multi-camera equipped studio allows synchronised capture of the foreground action and a visual hull computation is then used to compute a 3D model of that scene. The diffuse surface reflection parameters are computed using the 3D model from that process together with an illumination map of the studio. The illumination map is a high dynamic range image generated from a series of images of the studio using a camera equipped with a spherical (fish-eye) lens. With this setup our method is able to capture any action in the studio under normal lighting.
