Problems solved by technology

When the resolution of the reference image is high and the image quality is good, the matching accuracy between the remote sensing image and the reference image can often achieve high accuracy. At this time, the accuracy under the internal consistency constraint of the geometric model is lower than the matching accuracy between images. Geometry model global constraints do not improve matching accuracy

Abstract

The invention relates to a method for matching remote sensing images and reference images based on global geometric constraints, which is characterized in that it includes the following contents: constructing a remote sensing image imaging geometric model; reading reference image data and remote sensing images to be matched, and preprocessing the reference image data Obtain the reference image; preprocess the remote sensing image to be matched; perform affine-scale-invariant feature transformation matching on the reference image and the remote sensing image to be registered, extract feature points, and obtain the initial value of the least squares matching; based on least squares The initial value of the matching is the least squares matching through the globally constrained least squares matching model, and the radiation deformation parameters and geometric deformation parameters of the remote sensing images to be registered are output.

Description

A Matching Method of Remote Sensing Image and Reference Image Based on Global Geometric Constraints technical field [0001] The present invention relates to a method for matching a remote sensing image and a reference image based on global geometric constraints. Photogrammetry and remote sensing image processing technology field. Background technique In aerospace and deep space photogrammetry, using remote sensing images to perform geometric positioning, it is often necessary to correct the images. to a unified benchmark. In the correction of remote sensing images, it is necessary to establish a geometric model, that is, to construct an image coordinate and a reference coordinate system. relationship between. The geometric model can be obtained from the measurement and control parameters such as orbit and attitude when the remote sensing image is obtained, and can also be obtained from the image. The corresponding relationship established by matching with the benchm...
