Abstract

The present invention provides a method and system for detecting changes in areas, comprising: acquiring images at different times of an area by low-altitude UAVs; extracting state features for each of backbone feature pairs; analyzing importance of each of state parts due to the state parts have different importance degrees to the whole image features under different scenes; eliminating the state features from complete features by virtue of differences in importance degrees, to obtain corresponding essential parts; determining at least one change in the area by analyzing the essential parts. The invention comprehensively considers the importance of the state parts in the input images, and the essential parts contains complete and pure information are obtained, which reflects an actual changed region.
