论文_标定_A comparative review of camera calibrating methods with accuracy evaluation
07 Oct 2023比较老的论文,对比了几种方法:
- Hall
- Faugeras
- Faugeras with radial distortion
- Tsai 只考虑 radial lens distortion
- Weng 考虑三种 radial/decentering/thin prism lens distortion
其中 decentering/thin prism lens distortion 本质上还是引起径向和切向 tangential 畸变
搜原文直接用上面名字加上 calibration
当不考虑相机畸变,可以通过各种变换表示成矩阵相乘,然后用线性最小二乘求解内参(直接法,求伪逆),考虑畸变,只能非线性最小二乘迭代了
