Abstract

The invention discloses a landslide monitoring method and device, electronic equipment and a storage medium, which are used for solving the technical problem of low accuracy of landslide mass identification and risk evaluation in the existing landslide analysis method. The method comprises the following steps: acquiring an image before landslide and an image after landslide in a preset area, and comparing the image before landslide and the image after landslide to determine a landslide area; acquiring laser radar point cloud data of a landslide occurrence area in the image before landslide occurrence; preprocessing the laser radar point cloud data to obtain preprocessed data; classifying the preprocessed data to obtain ground point cloud data; generating a first digital elevation model by adopting the ground point cloud data; acquiring a second digital elevation model of the image after the occurrence of the landslide; and comparing the first digital elevation model with the second digital elevation model to obtain a landslide region division map.

Description

technical field [0001] The invention relates to the technical field of terrain analysis, in particular to a landslide monitoring method, device, electronic equipment and storage medium. Background technique [0002] The power system is a special and organic part of lifeline engineering. Its safe and reliable operation is not only affected by internal factors such as unsafe behaviors of people and unsafe states of mechanical equipment, but also by relatively sudden and destructive events. Threat of natural disasters. Among the threats of various natural disasters, landslides are large in number, large in scale, strong in regionality, complex in nature, and have great harm and certain regularity. There are more transmission lines than in the field, which are characterized by many points, sites, and wide areas, and are vulnerable to natural disasters such as landslides. However, the scope of landslide disasters is small and fragmented, and it is difficult to achieve accurate p...
