Abstract

Die vorliegende Erfindung offenbart ein Verfahren und ein System zur Gewinnung von Informationen über Winkelanomalien aus Fernerkundungsdaten und bezieht sich auf den Bereich der Mineralexploration Das Verfahren umfasst hauptsächlich Speichern der erhaltenen Fernerkundungsdaten in einem Arbeitsbereich bandbreitenweise, um einen Fernerkundungsdatensatz zu bilden (102), Durchführen einer Winkelumwandlung der Daten in dem Fernerkundungsdatensatz, um einen spektralen Winkeldatensatz zu erzeugen (103), und Extrahieren von Winkelanomalieinformationen aus den Fernerkundungsdaten aus dem spektralen Winkeldatensatz unter Verwendung einer orthogonalen Zerlegungstechnologie (104) Die vorliegende Erfindung kombiniert spektrale Merkmale und spektrale Unterschiede und extrahiert Winkelanomalie-Informationen, wodurch bessere Ergebnisse erzielt werden als durch die Extraktion gewöhnlicher Anomalie-Informationen aus FernerkundungsdatenThe present invention discloses a method and system for obtaining information about angular anomalies from remote sensing data and relates to the field of mineral exploration. The method mainly comprises storing the obtained remote sensing data in a workspace band by band to form a remote sensing data set (102), performing an angle transformation the data in the remote sensing data set to generate a spectral angle data set (103), and extracting angle anomaly information from the remote sensing data from the spectral angle data set using an orthogonal decomposition technology (104) The present invention combines spectral features and spectral differences and extracts angle anomaly information, yielding better results than extracting ordinary anomaly information from remote sensing data
