Toward High Fidelity 3D Video: Multiple Active Camera Assignment

In this paper, we present a multiple active camera assignment for high fidelity 3D video of a moving object, mainly an acting human body. The camera system is made up of cameras with long focal length lenses for high resolution input images. However, such cameras can capture only partial views of the object. Our goal is to assign the camera set to the different parts of the moving object so as to achieve a high visibility of the whole object. For each camera, we evaluate the visibility to the different regions of the object, corresponding to different camera orientations and with respect to its field of view (FOV). Thereafter, we assign each camera to one orientation in such a way to maximize the visibility to the whole object. in order to temporally extend this scheme, we involve, in addition to the visibility analysis, the last camera orientation as an additional constraint. The purpose is an optimized camera movement.
