| Abstract;To understand a dynamic 3D scene by multiple cameras, the characteristics as well as locations and poses of the cameras must be identified. For such the dynamic scene understandings, the conventional camera calibration techniques using some specific calibration objects has a limitation. In the application here, the object shapes are unknown, and some camera parameters such as focal length and camera pose like to be variable. Then, so-called the self-calibration must be employed, where the camera parameters and the object shapes are identified simultaneously and dynamically. In this paper, we introduce our strategy of implementation for the calibration for multi-view cameras based on the self-calibration, show the experimental results, and discuss the problems concerning the dynamic calibration of the multi-view cameras.
