In this paper, we describe a method to photogrammetrically estimate the intrinsic and extrinsic parameters of fish-eye cameras using the properties of equidistance perspective, particularly vanishing point estimation, with the aim of providing a rectified image for scene viewing applications. The estimated intrinsic parameters are the optical center and the fish-eye lensing parameter, and the extrinsic parameters are the rotations about the world axes relative to the checkerboard calibration diagram.
在本文中,我们描述了一种使用等距透视特性(特别是消失点估计)来摄影测量估算鱼眼相机的内参和外参的方法,目的是为场景查看应用提供校正后的图像。所估计的内参是光心和鱼眼镜头参数,外参是相对于棋盘标定图绕世界轴的旋转。
