Abstract

The invention discloses an optical satellite remote sensing image detection method. The invention provides an optical satellite remote sensing image detection method, and the method comprises the steps: obtaining an optical satellite remote sensing image, extracting a shadow region in the optical satellite remote sensing image, carrying out the shadow region reconstruction processing of the shadow region, and constructing a ratio graph and a multi-scale detail graph based on the optical satellite remote sensing image after the shadow region reconstruction processing. Performing binaryzation on the multi-scale detail image, distinguishing a target area, extracting an area of interest from a downward-looking image of the target area, performing prediction of the same area of interest on a forward-looking image and a backward-looking image in the target area according to the area of interest, and performing prediction of the same area of interest on the basis of epipolar constraint conditions. And performing least square matching on the downward-looking image, the forward-looking image and the rear-looking image, and performing forward intersection according to a matching result to obtain a digital earth surface model, so that 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 the film or photo that records the electromagnetic wave size of various ground features, 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 and regional reconnaissance, as well as civilian fields such as disaster monitoring, emergency relief, and disaster prevention and early warning. [0003] The Chinese patent with application number 202110879945.5 discloses a processing method for remote sensing satellite image data, which includes the following steps: S1. Use source coding to assign independent data identifiers to remote sensing...
