Abstract

The invention is suitable for the technical field of image processing, and provides a ground object change detection method, a ground change detection system and a terminal, and the method comprises the steps: obtaining a first image before a ground object changes and a second image after the ground object changes in a target region; inputting the first image and the second image into a feature differential convolutional neural network model to obtain an output first change intensity graph; and based on the first change intensity map, generating a binary image of ground object change. The method, the system and the terminal improve the robustness and stability of remote sensing image change detection, and improve the precision of change detection.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a detection method, detection system and terminal for ground object changes. Background technique [0002] Remote sensing images can directly or indirectly reflect land cover and land use information, and are an important means to obtain information on changes in the earth's surface. Change detection in remote sensing images refers to the process of identifying changes in remote sensing images of the same geographic location at different times. Change detection based on remote sensing images has important applications in geological disasters, urban changes, environmental monitoring, agriculture, forestry and other fields. [0003] In recent years, the emergence of high-spatial-resolution and high-time-resolution remote sensing images from a variety of sensors has put forward new requirements for change detection algorithms, which need to quickly ob...
