Abstract

The embodiment of the invention discloses a three-dimensional modeling method and device for a building. Wherein, the method includes: the building three-dimensional modeling device can generate the building three-dimensional white model of the area to be modeled in batches according to the vector outline data and height data of the building, and can determine the building type based on the POI data, so as to search according to the type Corresponding texture data, the corresponding texture data is uniformly applied to the same type of building 3D white model, so that the building 3D model of the area to be modeled can be quickly established, and the efficiency of building 3D modeling can be improved. Since this method does not need to model buildings one by one, it can reduce input costs 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...
