Problems solved by technology

[0005] In order to solve the problem that the abnormal information of gypsum salt is hidden in the various information of hydroxyl and carbonate anomalies in the prior art when the abnormal information of mineralization and alteration is used to extract the abnormal information, which leads to difficulties in extraction and limited application, the present invention provides a remote sensing image paste Salt information extraction method, which uses multi-pole driven orthogonal transformation iterative technology for information extraction, realizes the separation of gypsum and salt information on the basis of hydroxyl and carbonate anomalies, and the extracted anomalies have good results

Abstract

The present invention provides a method and device for extracting paste and salt information from remote sensing images. The method includes: first step, acquiring remote sensing image data and using mask technology to process and form basic data; second step, performing basic data in a selected area The histogram calculation process determines the selected data, and then uses the first-order orthogonal transformation method to extract the abnormal information of the group from the selected data, and performs cutting and verification of the abnormal information; the third step is based on the abnormal information of the group Combined with the multi-level drive orthogonal transformation iteration technology to obtain the abnormal information of the salt and paste, and at the same time, the abnormal information of the salt and paste is judged to meet the verification requirements, and then the abnormal information of the salt and paste is cut and processed and output. This method can obtain more accurate gypsum-salt anomaly information and suppress non-gypsum-salt information, which is conducive to faster and more accurate optimization of prospecting target areas, and can save time, manpower and material resources for mineral investigation work.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a method and device for extracting gypsum-salt information from remote sensing images. Background technique [0002] Alteration remote sensing anomaly information is quantified and extracted from remote sensing data by mathematical means, and is used to characterize the indication information of near-mine alteration rocks that may be most related to mineralization. At present, the alteration remote sensing anomalies in many literatures mainly include altered minerals and their combination information including electronic anomalies (original iron staining anomalies) and group anomalies (original hydroxyl anomalies and carbonates). The sign of ore has its geological and spectral basis, and has been proved and widely used in practice. [0003] The formation process of ore deposits is a gradual enrichment process of some useful elements, and this metallogenic material is usuall...
