Remote sensing image change detection method and device

Abstract

The invention provides a remote sensing image change detection method and a remote sensing image change detection device, which can reduce the uncertainty in remote sensing change detection and improve the precision of remote sensing image change detection. The method comprises the steps of obtaining multi-source information used for detecting whether a remote sensing image changes or not; carrying out rasterization processing on each kind of source information to obtain raster data; for each piece of raster data, taking a central point of each raster as an information point, generating pointdata, and storing the point data into a database by taking coordinates of the information points as main keys; carrying out neighborhood analysis on the information in the database to obtain spatial neighborhood features, and storing the spatial neighborhood features into the database; and acquiring data from the database to generate a training set, training a remote sensing image change detectionmodel, wherein the trained remote sensing image change detection model is used for detecting whether a certain place changes or not. The invention relates to the field of remote sensing image changedetection.

Description

technical field [0001] The invention relates to the field of remote sensing image change detection, in particular to a remote sensing image change detection method and device. Background technique [0002] In the early days of remote sensing, change detection has become one of the application areas that people generally pay attention to. With the development of computers, satellite sensors, information processing and other technologies in recent decades, remote sensing image change detection has received a lot of research and made significant progress in terms of theoretical system, technical methods, and application fields. In terms of methods, it includes algebraic method, transformation method, model method and other methods. These methods perform change detection tasks for different information from different angles. However, there is a lack of comprehensive utilization of multi-source information. For example, it often focuses on a single spectral feature. However, sin...
