Abstract

The application discloses a monitoring method, device and computer equipment for building changes, which relate to the field of computer technology and can solve the problems that the current monitoring methods for building changes have limitations, low monitoring accuracy, and difficulty in meeting building change monitoring requirements. Wherein the method comprises: obtaining the airborne LiDAR LiDAR data of the time phase before and after the area to be monitored; separating the non-ground points from the preprocessed LiDAR data according to the point cloud filtering algorithm; using the non-ground points to extract the area to be monitored Corresponding to the building outlines of the preceding and following time phases; determining the state change information of the building based on the building outlines. This application is suitable for the monitoring of changes in buildings.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a monitoring method, device and computer equipment for building changes. Background technique [0002] Half of the planet's population lives in urban areas. As a human-dominated area, a large number of buildings are demolished, newly built or remodeled in big cities every year. On the one hand, building a model to describe the trajectory of building changes is a key step in updating maps and 3D models in geographic databases; on the other hand, new construction, renovation and demolition of buildings will inevitably change the 3D morphological characteristics of urban space This change significantly affects the local climate of the urban area and the energy balance of the urban area. Therefore, the detection of changes in building types, three-dimensional morphological parameters, and landscape patterns from different scales has gradually become an important researc...
