Abstract

With the advantage of having a large field of view, fisheye cameras are widely used in many applications. In order to generate a precise view, calibration of the fisheye cameras is very important. In this paper, we propose a method of extrinsic parameters calibration of multiple fisheye cameras working in man-made structures. A Manhattan Worlds space assumption is used, which describes man-made structures as sets of planes that are either orthogonal or parallel to each other. The orientation of the cameras is obtained by extracting vanishing points that denote orthogonal principal directions in different images captured by the cameras at the same time. With the proposed method, the calibration of extrinsic parameters is very convenient and the system can be recalibrated remotely.
