| Abstract(in English) | For calibration of general radially symmetric distortion of omnidirectional cameras such as fish-eye lenses, calibration parameters are usually estimated so that curved lines, which are supposed to be straight in the real-world, are mapped to straight lines in the calibrated image, which is called plumbline principle. Under the principle, the calibrated image is the image taken by an ideal pin-hole camera. The authors proposed a calibration method based on the plumbline principle, which consists of linear algorithm, however, the method is only for the camera of which field of view is less than 180 degree. Then in this paper, the authors propose a calibration method based on the stereographical plumbline principle, which is an extension of plumbline principle to apply for the camera of which field of view is over 180 degree. The proposed algorithm only consists of linear algorithm. |
