Two View Geometry Estimation with Outliers 

C++ code for finding the relative orientation of two calibrated cameras in presence of outliers. The obtained solution is optimal in the sense that the number of inliers is maximized.

Pose with Radial Distortion

Matlab code for solution to the minimal problem of pose with unknown focal length and radial distortion.

• pose_radial.zip

This code is written for the paper:

• Pose Estimation with Radial Distortion and Unknown Focal Length

Relative Pose with Radial Distortion

Matlab code for two minimal cases on relative pose and radial distortion. The minimal cases are: (i) simultaneous estimation of essential matrix and a common radial distortion parameter for two partially calibrated views and six image point correspondences and (ii) estimation of fundamental matrix and two different radial distortion parameters for two uncalibrated views and nine image point correspondences.
