| 摘 要： | 对于精度要求高、成本低或使用广角镜头的系统,在标定摄像机参数时需要校正镜头畸变.通常在摄像机标定算法中,镜头畸变参数的校正和摄像机参数求解都结合在一起,增加了算法的复杂性,并且依赖标定模板.针对以上问题,提出了一种新的标定方法,即不需要标定模板,也不需要确定空间点的精确坐标.首先通过直线的射影不变性校正镜头畸变参数,再...

| Abstract: | In low cost cameras and widcangle cameras, lens distortion should be calibrated. In traditional methods, camera's interior parameters and lens distortion are calibrated together. In this work,we presented a method to calibrate distortion and camera's parameters, without any calibration objects and 3D coordinates. Lens distortion was corrected based on the projective invariant of straight lines,orthogonal straight lines were used to calibrate camera's interior parameters. The accuracy and availability of the method were verified on the experimental result of simulation and real data. |
