Abstract

The invention relates to the technical field of artificial intelligence image segmentation, target detection and classification, in particular to a building change detection method based on remote sensing images and a twin neural network, and the method comprises the steps: obtaining a data set containing a plurality of pairs of remote sensing images; dividing the data set into a training set, a verification set and a test set, and cutting remote sensing images in the training set, the verification set and the test set; training the clipping training set remote sensing image to obtain a network model weight file; and testing the clipping test set remote sensing image according to the network model weight file to obtain a building change result. The method has the advantages of automation, intellectualization and rapidness, and for two input remote sensing images subjected to radiation correction of front and back time phases, the remote sensing images only need to be input into an algorithm interface for preprocessing and then are transmitted to a network. According to the method, efficient and accurate positioning and end-to-end detection of changing buildings in front and back time phase remote sensing images are realized, operation is simple after deployment, and a building change detection result is reliable.

Description

technical field [0001] This application relates to the technical fields of artificial intelligence image segmentation, target detection and classification, and in particular to a building change detection method based on remote sensing images and twin neural networks. Background technique [0002] Requirements for the construction of the ground object change and classification detection test site: acquisition of multi-temporal image data; reproducible physical surface object changes; change detection and change analysis; standardized output of ground object change true value results. [0003] The ground object change scene analysis unit mainly realizes the function of satellite remote sensing image change detection, which is divided into two parts: change detection and change analysis. The change detection part mainly realizes the detection of the changed area for the input multi-temporal satellite remote sensing image. According to the technical process, it includes necess...
