Real scene three-dimensional rapid modeling method based on remote sensing image

The invention discloses a live-action three-dimensional rapid modeling method based on a remote sensing image, and belongs to the technical field of image processing. After multi-angle remote sensing images are shot, contour pixel points are screened out for each remote sensing image, a contour map is constructed, so that an object structure in each remote sensing image is presented, then a detection window is set, and the real-action three-dimensional rapid modeling method based on the remote sensing image is realized. The method comprises the following steps: detecting a plurality of pairs of matching points from every two profile diagrams, registering each remote sensing image according to the positions of the matching points, optimizing the overlapped part of the registered image, reducing the problem of splicing seams and the visual continuity, and performing three-dimensional curved surface reconstruction on the optimized registered image to obtain a three-dimensional image.
