Building volume data estimation method and device, equipment and storage medium

Abstract

The invention discloses a building volume data estimation method and device, equipment and a storage medium, and the method comprises the steps: carrying out the ground point filtering of dense matching point clouds of a building region, and obtaining non-ground point clouds; clustering horizontal point clouds in the non-ground point clouds, and removing non-roof surface point clouds of point cloud patches obtained through clustering from a grid plane; determining a topological relation between the point cloud patches based on the grid plane, carrying out building division, and carrying out structured segmentation on building monomers in a building to obtain a point cloud extraction result; carrying out contour vectorization and eave correction on the building; subdividing the building, and obtaining a structure vectorization result including balcony structure information and floating building structure information based on a section contour obtained through subdivision and a contour vectorization result obtained after eave correction; and estimating building volume data according to the point cloud extraction result and the structure vectorization result. According to the invention, automatic estimation of the building volume data can be realized, and the efficiency of obtaining the building volume data is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method, device, terminal equipment and computer-readable storage medium for estimating building volume data. Background technique [0002] Building volume refers to the volume of a building in space, including the length, width, and height of a building. The size of the building has a great influence on the urban space. The space of the same size is surrounded by large buildings and small buildings, giving people a completely different feeling of space. Therefore, the acquisition of The building volume data in the building area is of great significance to urban planning. [0003] At present, the building volume data in the building area is mainly obtained through manual means. The use of total station or household measurement and other house measurement methods consumes a lot of manpower, and the data production cycle is long; in addition, there are also unmann...
