An Effective Camera Calibration Method for Multiple Videos Recording with Static and Active Cameras

摘要

We introduce an effective camera calibration method for multiple videos recording. In our target space, there are both of static cameras and active cameras. In order to reconstruct accurate 3D shape information, we have to capture high-resolution multiple images which are calibrated accurately. Static cameras can be accurately calibrated, but, because of their narrow field of view, we need huge number of cameras to capture whole of 3D space. On the other hand, active cameras allow capturing high-resolution multiple images, but it is difficult to calibrate them accurately. We introduce our multiple videos capturing system that combine multiple static cameras and active cameras. And we propose an effective camera calibration method which works well in such an environment.
