Estimation method, device, equipment and storage medium for building mass data

Abstract

The invention discloses a method, device, equipment and storage medium for estimating building volume data. The method includes: performing ground point filtering on a densely matched point cloud in a building area to obtain a non-ground point cloud; The point cloud is clustered, and the non-roof surface point cloud of the point cloud patch obtained by clustering is eliminated on the grid plane; the topological relationship between the point cloud patches is determined based on the grid plane, and the building building is divided, and the building Structural segmentation of the building monomer in the building to obtain point cloud extraction results; contour vectorization and eave correction of the building building; subdivision of the building building, based on the section contour obtained by segmentation and contour vectorization after eave correction As a result, the structure vectorization results including balcony structure information and floating building structure information are obtained; according to the point cloud extraction results and the structure vectorization results, the building volume data is estimated. The invention can realize automatic estimation of building volume data, and improves the efficiency of acquiring building volume data.

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...
