Abstract

A remote sensing image geometric normalization method and apparatus. The method comprises: constructing a pyramid tile structure for a reference image, and releasing reference tile data; calculating the level of a tile to be downloaded and the name of the tile to be downloaded, and downloading corresponding data from the reference tile data to obtain a standard tile set; performing first geometric correction on the image to be subjected to geometric normalization and tiles in the standard tile set to obtain a first image processing result; matching the first image processing result with the tiles in the standard tile set to obtain a plurality of control points, and calculating a result evaluation precision; and determining whether to perform second geometric correction on the first image processing result.
