Accurate mirror-based camera pose estimation with explicit geometric meanings

扫码查看
An accurate closed form solution is proposed to estimate camera pose by several mirrored reference object images acquired via a planar mirror under different unknown poses.Compared with state-of-the-art methods,our method is more accurate when there are more than three images and has explicit geometric meanings.This method also properly handles cases in which some of the mirror poses are parallel.The central idea is to minimize an error metric based on all reflections of rotation,which enables the camera rotation to be estimated directly by SVD of sum of mirrored camera rotations.After that,the camera translation is computed by solving a large system of linear equations to minimize object space collinearity error.Both synthesized data and real data experiments show the advantages of our approach.
