Problems solved by technology
[0004] However, SAR interferometry is limited by its imaging geometry, and cannot effectively monitor its azimuth deformation.
In addition, due to the influence of undulating terrain, radar shadows, overlapping, top-bottom inversion and other phenomena still cannot be overcome, resulting in the inability to accurately obtain the deformation of the ground surface only by using synthetic aperture radar interferometry technology. Correspondingly, the monitoring of geological disasters and less effective in preventing

The application provides a geological disaster monitoring method, device and computer equipment, belonging to the technical field of disaster prevention. The method includes: acquiring regional information of a target area, where the regional information includes radar images, digital elevation models and optical remote sensing images; determining geological disaster identification conditions of the target area according to the regional information of the target area, and the geological disaster identification conditions include: the surface of the target area Deformation time series, terrain conditions, and classification map of vegetation and features; determine target sub-regions that meet preset conditions according to the surface deformation time series, terrain conditions, and classification images of vegetation and features in the target area; perform geological hazard monitoring on the target sub-region. The present application can improve the accuracy of geological disaster monitoring and prevention.
Description
technical field [0001] The present application relates to the technical field of disaster prevention, in particular, to a geological disaster monitoring method, device and computer equipment. Background technique [0002] With the intensification of human activities, geological disasters such as land subsidence, ground fissures, landslides, collapses, subsidences, and debris flows are gradually intensifying. These disasters have brought great damage to people's life and property, economic development and social stability. [0003] In order to monitor and prevent these geological disasters, the method adopted in the prior art is to use synthetic aperture radar interferometry technology to monitor the ground surface all-weather and all-weather, so as to determine the deformation of the ground surface, and then prevent geological disasters. [0004] However, SAR interferometry is limited by its imaging geometry, and cannot effectively monitor its azimuth deformation. In addit...
