To recover the position of occlusion ,an occlusion recovery method based on orthogonal complement subspace is presented .Two images are combined into a group and the occlusions in the group are removed .Then ,the position of occlusion is linearly obtained ,based on the fact that the sum of orthogonal complement subspaces spanned by all the image groups equals to the one spanned by the 3D space structure points .Being linearly ,the method for occlusion recovery overcomes the shortcoming that some existing iteration methods need a good original value .At the same time ,all the images and all the image points are treated uni-formly .The experiments with both simulate and real data show that the method is efficient ,robust and has small re-projection errors .
