Obtaining three-dimensional information of targets from inverse synthetic aperture radar image sequences is crucial. Reflected in target recognition, spatial monitoring, and other aspects. In this paper, the Feature matching algorithm based on LoFTR (Local Feature based Transformer) is used to extract the associated position information of the target strong scattering points. After obtaining the horizontal and vertical coordinate information of the target, adjust the image center uniformly to generate an observation matrix. Finally, the three-dimensional coordinate information of the target is obtained through factorization, and the shape and structure of the target are reconstructed. And achieving good reconstruction results through fusion of reconstruction results . By processing the continuous ALOS satellite image, the three-dimensional position and shape reconstruction results of the target's strong scattering points are obtained.The reconstruction results show that this method can reconstruct the three-dimensional position and shape information of the target from two-dimensional multi-angle ISAR images.
