On the choice of the correlation term for multi-baseline stereo-vision
Martial Sanfourche · 2004
We address DSM reconstruction from calibrated limited-angle aerial side-looking image sequences. We use a regularised approach which combines a multi-view pixel-wise similarity criterion and a L1-norm regularisation term. Although it gives quite good results, it has two main drawbacks: occlusions are not dealt with and the reconstruction improvement brought by addition of a new view becomes negligible beyond a certain number of views. We argue that these problems result from lacks of goodness-of-fit term. We propose to modify this term in order to obtain high resolution DSMs with occlusions handling. First developed on synthetic sequence, these modifications are evaluated here on a real sequence with good results. 1
