Multi-type anomaly on-orbit detection system and method

Abstract

The present application relates to the technical field of anomaly feature recognition, in particular to a multi-type anomaly on-orbit detection system and method, the system comprising: a map collaborative cutting module, a redundant partition identification module, a wave band boundary discrimination module, a sensitive feature generation module and an anomaly structure construction module.In the present application, by extracting the spatial positioning information of remote sensing images and performing image alignment, a pixel overlap distribution matrix is constructed, the adaptive division of map boundaries can be realized based on the frequency concentration area, the accuracy of image area management is improved, combined with main image extraction and boundary matching degree discrimination, the pertinence of anomaly area wave band recognition is effectively enhanced, multi-wave band gray values are combined into three-dimensional vectors, gray vector mapping is generated by coupling spatial position, the fusion expression of spectral and spatial features of thermal anomaly areas is realized, the spatially continuous gray anomaly area is aggregated by connectivity recognition, a stable anomaly structure distribution is constructed, and the recognition accuracy and adaptability in complex change scenarios are improved.
