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 mobile measurement system does not have precise geographic tags indoors, so maps, physical environment data and indoor ubiquitous positioning basis It is difficult to collect data through mobile measurement to improve the efficiency and automation of data collection and processing, which makes it difficult for ubiquitous positioning methods and corresponding navigation and location service applications to be accepted by the market

[0017] In traditional methods, the accuracy of the fingerprint feature database is closely related to the accuracy of the geographic location labels of the fingerprint feature database training points; to improve the accuracy of the fingerprint feature database, it is required to know the precise coordinates of the fingerprint database training reference points. The space lacks effective means to obtain the precise coordinates of the reference point, making the deployment, maintenance, and update of the entire positioning system time-consuming and laborious, and the cost increases

Therefore, in the traditional method, improving the accuracy of the fingerprint library and reducing the cost of the system have become a pair of contradictions;
