Problems solved by technology

At present, the integration of these technologies and the public demand for Location Based Service (Location Based Service) can no longer satisfy the positioning and navigation service mode of the existing two-dimensional planar map scene, and the "immersive" real-scene indoor positioning and navigation Relevant applied research 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 positioning and navigation of mobile phones.

Abstract

Embodiments of the present invention provide a terminal indoor positioning method and system, the method comprising: obtaining the strength of multiple broadcast signals received by the terminal to be tested; The distance of a signal sending device; according to the preset three-dimensional coordinates of each signal sending device and the distance between the terminal to be tested and each signal sending device, the initial three-dimensional coordinates of the terminal to be tested are obtained; according to the current indoor three-dimensional building map of the terminal to be tested , correct the initial three-dimensional coordinates, and obtain the best three-dimensional coordinates of the terminal to be tested. In the embodiment of the present invention, the initial three-dimensional coordinates of the terminal to be tested can be calculated by combining the strength of the broadcast signal received by the terminal to be tested with the preset three-dimensional coordinates of each signal sending device, and combined with the indoor three-dimensional building map, the The initial three-dimensional coordinates of the terminal are corrected, thereby improving the accuracy of the terminal's indoor positioning.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a terminal indoor positioning method and system. Background technique [0002] With the rapid development of mobile GIS, smartphones, close-range photography, augmented reality, deep learning and other disciplines, and the arrival of the 5G era, there is an increasing demand for indoor 3D visualization scene positioning and navigation. At present, the integration of these technologies and the public demand for location-based services (Location Based Service) can no longer satisfy the existing positioning and navigation service mode of two-dimensional planar map scenes, and the "immersive" real-scene indoor positioning and navigation Related applied research has shown a rapid growth trend. However, there is still no effective and complete solution to scientific problems such as efficient construction of indoor and outdoor 3D real-scene maps of buildings and indoor posit...
