Abstract

The invention discloses an optical satellite remote sensing image detection method. The invention provides an optical satellite remote sensing image detection method, which extracts the shadow area in the optical satellite remote sensing image by acquiring the optical satellite remote sensing image, performs shadow area reconstruction processing on the shadow area, and reconstructs the processed optical satellite based on the shadow area Remote sensing image, construct ratio map and multi-scale detail map, binarize multi-scale detail map, distinguish target area, extract interest area in the bottom view image of target area, according to the area of ​​interest, in the target area Predict the same region of interest on the front-view image and the rear-view image. Based on the epipolar constraints, perform the least squares matching of the three images on the bottom-view image, front-view image, and rear-view image, and perform forward intersection according to the matching results. , the digital surface model is obtained, and the processing efficiency of remote sensing satellite image data is further improved.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to an optical satellite remote sensing image detection method. Background technique [0002] Remote sensing image (abbreviation: RS, English: Remote Sensing Image) refers to films or photos that record the size of electromagnetic waves of various ground objects, mainly divided into aerial photos and satellite photos. With the rapid development of optical satellite remote sensing images, this technology plays an extremely important role in military applications such as homeland defense, regional reconnaissance, and civil fields such as disaster monitoring, emergency disaster relief, and disaster prevention and early warning. [0003] The Chinese patent with application number 202110879945.5 discloses a method for processing remote sensing satellite image data, including the following steps: S1, using source coding to allocate independent data identifiers for remote sensing sat...
