Problems solved by technology

[0002] Because the shooting angles of the multi-view linear array remote sensing images acquired by satellite multi-angle fast imaging change greatly, the matching between this kind of oblique linear array remote sensing images is more difficult than the matching between non-oblique frame remote sensing images.
These difficulties are mainly reflected in: compared with frame remote sensing images, linear array remote sensing images have the characteristics of multi-center projection, so the geometric relationship of linear array remote sensing images is more complex
In addition, due to different camera angles between oblique images, there are problems such as large geometric distortion on the image, serious occlusion of ground objects, and differences in grayscale and texture.

Abstract

The invention provides an image matching method and device for a multi-view large-tilt linear array. The method comprises the steps that CCD satellite remote sensing images, in a preset number, of the large-tilt linear array are corrected to be horizontal images based on an anti-analytic rational function model; resampling is performed on the horizontal images obtained after correction, and the horizontal images obtained after resampling are subjected to image pair matching according to preset global matching rules; and multi-baseline verification is performed on the image pair matching result to remove mismatching point pairs and discontinuous matching point pairs in the image pair matching result. Through the image matching method and device for the multi-view large-tilt linear array, image matching of the multi-view large-tilt linear array can be performed accurately.
