Document Type and Number:
WIPO Patent Application WO/2024/012024
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for evaluating the geometric quality availability of an optical remotely-sensed image. The method specifically comprises: parsing optical remotely-sensed image data to obtain an original multispectral image and an original panchromatic image, and obtaining a basic homologous point set by means of feature point extraction and feature registration; optimizing the basic homologous point set by using an optimization policy to obtain a first homologous point set; performing homologous point pair selection on the first homologous point set on the basis of geometric importance and distribution balance to obtain a second homologous point set; performing calculation on the second homologous point set to obtain geometric precision; and performing availability determination on the basis of the geometric precision to obtain geometric quality availability. According to the present invention, the geometric positioning precision and geometric consistency of a satellite remotely-sensed image can be comprehensively characterized, geometric quality evaluation and availability evaluation of an image can be quickly and automatically performed, and subsequent image processing and product production are supported.
