摘要

To meet the high-precision calibration demands of fisheye lens,this paper proposes a linear calibration method based on the division distortion model.The method converts the calibration problem into solving linear equation sets with a division model.Center of camera distortion located,the distortion equation is decoupled from the projection matrix,and the intrinsic and extrinsic parameters of the camera and distortion coefficients are solved respectively.Then,the robust calibration of fisheye lens can be completed.Experimental results show that compared with non-linear calibration methods,the proposed method increases computational efficiency about 10 times while keeping the accuracy and reliability of calibration.
