Fast iterative five point relative pose estimation

2013 IEEE Workshop on Robot Vision (WORV), 2013
Robust estimation of the relative pose between two cameras is a fundamental part of Structure and Motion methods. For calibrated cameras, the five point method together with a robust estimator such as RANSAC gives the best result in most cases. The current state-of-the-art method for solving the relative pose problem from five points is due to Nister ...
