Abstract: In this paper,for three-linear array stereo-imagery of Mapping Satellite-1,semi-global matching algorithm based on mutual information is researched and used in three-dimensional reconstruction.The pyramid and multiple-baseline matching strategy is adopted and mutual informationof per-pixel is regarded as matching unit and full matching is realized,according to the principle of energy function minimization.The experimental results show that the proposed method can accurately realize three-dimensional reconstruction for Mapping Satellite-1 imagery.

Key words: image matching, semi-global, mutual information, three-dimensional reconstruction
