Multi-dimensional information synchronous acquiring, positioning and position service device as well as system and method

Abstract

The invention belongs to the fields of navigational positioning and position service, and discloses a multi-dimensional information synchronous acquiring, positioning and position service device as well as system and method. Multi-dimensional information data which comprises a navigational and position service map, indoor space environment information and geographic position reference thereof needed for indoor navigation and position service as well as ubiquitous positioning signal data and geographic position marking thereof needed for indoor positioning are synchronously acquired and generated, geographical distribution of ubiquitous positioning signal feature is reconstructed or a spatial position of a signal source is calculated, so that an indoor ubiquitous positioning base information database is constructed, and therefore, a complete technical scheme for indoor navigation and position service application construction, deployment, maintenance and updating for a mobile phone or other mobile equipment is provided. The mobile mapping technology and method improves operation efficiency of a navigation and position service data acquisition site, has high usability, and remarkablyreduces data acquisition, application maintenance and updating cost.

Description

technical field [0001] The invention belongs to the field of navigation, positioning and location services, and in particular relates to a multi-dimensional information synchronous collection, location and location service device, system and method. It specifically relates to a device and data processing method for fast, efficient, and integrated collection of indoor spatial geometric structure, environmental information data, and indoor ubiquitous positioning signal data, and a low-cost, high-efficiency development, deployment, and maintenance of indoor navigation and positioning and location service applications. Background technique [0002] The mobility of people and things in modern life is becoming more and more important, and the demand for diversified and personalized location information services is also showing a substantial growth trend. People spend more than 80% of their time living and working indoors, and more than 90% of the information about people and obje...

AI Technical Summary

Problems solved by technology

[0011] (1) In the prior art, the high-precision positioning system requires special hardware, and the cost of the whole system is very high

[0012] (2) In the existing technology, various elements required for indoor navigation and location services, such as maps, indoor space environment information, indoor positioning basic data, etc., are collected separately by different devices, and the collection process is cumbersome and the collection efficiency is low;

[0013] (3) The collection process of the above-mentioned various elements does not achieve mobile collection, the collection process lacks accurate geographical location reference, and the automation degree of the collection process and later data processing is low

[0014] (4) The low degree of automation, cumbersome and time-consuming acquisition process of ubiquitous signal fingerprint library data is the main factor affecting the popularization of fingerprint matching indoor positioning technology application

In outdoor space, satellite positioning technology can continuously provide precise reference position for mobile measurement system, but satellite positioning technology is not available indoors, so mob
