Abstract

In this paper, we are concentrating on the passive geometric camera calibration, which calculates the geometric parameters of all cameras in a camera system based on certain predefined object. The to-becalculated parameters include intrinsic parameters (e.g. focal length and aspect ratio) and extrinsic parameters (camera 3D position and orientation). Geometric camera calibration is the first and fundamental step in e.g. 3D measurement and 3D reconstruction systems. Its accuracy always determines the quality of those systems. Based on deliberately built calibration object, passive camera calibration can generate highly accurate parameter approximation of the camera system. However, past research mainly focused on either single or stereo camera systems, few have studied calibration of multi-camera and special camera systems (e.g. mirror based cameras). In this paper, we will introduce a coherence systematic calibration system that is fully automatic, workable under difficult situations and applicable for single, stereo, and multiple normal or special camera systems.
