Abstract

The embodiments of the invention disclose a building 3D modeling method and device. The method includes the following steps: a building 3D modeling device generates 3D white models of buildings in a to-be-molded area in batch according to the vector contour data and height data of the buildings; the device determines the building type based on POI data; the device finds out corresponding texture data according to the type; and the device applies the corresponding texture data to the 3D white molds of buildings of the same type in a unified manner. Therefore, the 3D models of the buildings in the to-be-molded area can be built quickly, and the efficiency of building 3D modeling is improved. As there is no need to mold buildings one by one, the input cost can be reduced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for three-dimensional modeling of a building. Background technique [0002] With the development of communication technology, the transition of communication network planning and network optimization (abbreviation: network planning and network optimization) from the traditional two-dimensional platform to the three-dimensional platform has become a trend. Therefore, network planning and network optimization based on the three-dimensional city model can not only improve and The user's sensory experience is also an important reference to assist users in planning and decision-making. The existing 3D modeling technology is generally based on 3D max, sketch up and other modeling tools to model urban buildings one by one, but this method requires high manpower input costs and low efficiency. Contents of the invention [0003] The embodiment of the inventio...
