Laser reflective tomography imaging has a wide application prospect of space target remote sensing because its resolution is independent of distance. Before the reconstruction of the target image， the multi-angle echoes projection data need to be aligned with the rotation center of the target， which is the projection registration technique. This paper proposed a projection registration method based on the target contour auto-correction， and the experimental results show that the method is easy to implement on simple target since the registration center of rotation， can effectively reduce the number of laser pulses launch and detector receive random jitter caused by the interference， such as solved the problem of the fuzzy image， is a kind of LRTI multi-angle echoes registration of new ideas.
