Abstract

The embodiment of the invention provides an indoor three-dimensional modeling method and system. According to the embodiment of the invention, the collected point cloud data is used for registration,there is no need to calibrate the site, the data collection process is simplified, and the application range of the indoor three-dimensional modeling method is expanded. Besides, through inverted image deletion processing, the laser reflection influence in laser point cloud data acquisition is deleted, and the model reconstruction precision is improved. In addition, according to the embodiment ofthe invention, based on the reconstructed indoor three-dimensional model, the accurate measurement of the real indoor environment can be realized.

Description

technical field [0001] The invention relates to the technical field of map construction, in particular to an indoor three-dimensional modeling method and system. Background technique [0002] With the rapid development of computer technology, wireless positioning technology, earth information system and mobile Internet technology, location-based services have become a reality and have been widely used in practice. In indoor environments, such as airport halls, exhibition halls, warehouses, buildings, supermarkets, libraries, underground parking lots, railway stations and subway stations, it is often necessary to determine the location of mobile terminals or their holders, facilities and objects indoors. location information, and provide corresponding additional indoor location-based application services such as navigation and search queries. Therefore, the construction of indoor three-dimensional (3D) model, as a basic work, has been paid more and more attention. However, ...
