Abstract

The embodiment of the invention provides a building live-action map making method and system. The method comprises the steps of building a BIM model of a target live-action, carrying out the classification of a model structure of the BIM model according to a geometric structure, and obtaining a first classification geometric structure and a second classification geometric structure; according to the semantic type of the first classification geometric structure, storing the model data of the first classification geometric structure as first file format data; according to the semantic type of the second classification geometric structure, storing the model data of the second classification geometric structure as second file format data; and obtaining texture data of the target live-action, and performing coordinate matching on the texture data and the first file format data and the second file format data to obtain a live-action map corresponding to the target live-action. According to the embodiment of the invention, the precision of the indoor and outdoor live-action maps of a building is improved, so that the building live-action maps are more effectively applied to positioning and navigation of a three-dimensional scene.

Description

technical field [0001] The invention relates to the technical field of map making, in particular to a method and system for making a building real-scene map. Background technique [0002] With the rapid development of mobile geographic information system (Geographic Information System, referred to as GIS), smart phones, close-range photography, augmented reality, deep learning and other disciplines, the current integration of these technologies and oriented location-based service (Location Based Service, referred to as LBS) The needs of the public can no longer be satisfied with the positioning and navigation service mode of the existing two-dimensional planar map scene, and the application research on "immersive" real-scene indoor positioning and navigation has shown a rapid growth trend. However, at present, there is no effective and complete solution to scientific problems such as efficient construction of indoor and outdoor 3D real-scene maps of buildings and indoor posi...
