The calibration is based on viewing a planar calibration object. The intrinsic and extrinsic camera parameters are estimated from control point correspondences between the calibration plane and calibration images.

对两帧图像进行ICM调试.包含内容：1估计姿态和摄像机内参数；2两幅图做四次金字塔；3利用输入特征点采用ransac算法估计姿态R, T。4sift特征匹配；5摄像机标定。-ICM images on two debugging. Contains: 1 Estimated posture and intrinsic parameters 2 two plans to do four pyramids 3 using the input feature points using ransac

非常好用的matlab相机标定。可以自动估算出内部和外部参数-matlab toolbox for dot pattern based camera calibration. It estimates the intrinsic and extrinsic parameters of the cameras. The 3D model can be also refined via optional bundle adjustment
