Abstract
Calibration of the omnidirectional system is under the environment of single viewpoint calibration, but due to the con-straint condition of single viewpoint is harsh, the system is difficult to be accurately calibrated, so the research on the omnidirec-tional camera calibration problem under the non-single viewpoint has great value. This paper presents a calibration method of re-flector’ s position and attitude for non-single viewpoint catadioptric omnidirectional camera based on planar quadratic curve. The calibration process doesn’ t need nonlinear iteration, can directly obtain the analytical solution of the reflector’ s position and atti-tude parameters. Finally the paper gives experiments with calibration, the panoramic perspective and cylindrical image to verify the calibration results, which show that the proposed calibration method is accurate and effective, and the calculation is simple, it’ s easy to implement.关键词
