Research on building instantiation change detection method in high spatial resolution remote sensing image

Abstract

Remote sensing building change detection is a key technology for understanding urban land cover and land use. In order to improve the accuracy of building change detection, this paper firstly summarizes a set of optimized building change detection methods for high resolution remote sensing images, and then introduces the steps of the method and the optimization part in detail. Finally, the feasibility of the optimized change detection method was verified in the experimental area. The results of this method are verified by an empirical experiment on the urban sub-center of Tongzhou District. The results show that this method can complete the remote sensing building change detection task under the condition of setting fewer parameters and large change area.
