Problems solved by technology
However, indoor wireless network devices may change, for example, some wireless network devices are moved, some wireless network devices fail, or some wireless network devices are added, etc., the distribution of signals in the indoor environment will also change accordingly, resulting in As time goes by, the matching degree between the positioning fingerprint library and the current signal environment is getting lower and lower, and the positioning accuracy is getting lower and lower, and even the positioning cannot be completed, and the positioning fingerprint library is almost invalid.

Embodiment Construction
[0077] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0078] Some concepts involved in the embodiments of the present application are introduced below.
[0079] Positioning fingerprint library: a database that provides positioning basis for indoor positioning technology. The location fingerprint library is established by measuring the signal strength from each wireless network device at each preset location point within the set range, including location fingerprint data corresponding to each preset location point within t...

The invention provides a positioning fingerprint updating method and device, a storage medium and electronic equipment, and belongs to the technical field of computers. According to the invention, a positioning log of a set space is compared with a positioning fingerprint database corresponding to the set space; wireless network equipment of which the state changes in the set space is determined;and then the positioning fingerprint database corresponding to the set space is automatically updated according to the wireless network equipment of which the state changes, so that the matching degree of the positioning fingerprint database and the current signal environment is improved, and the positioning precision and the positioning accuracy of indoor positioning by using the positioning fingerprint database are improved. Meanwhile, the positioning fingerprint database can be updated in real time by adopting the method, so that the service life of the positioning fingerprint database is prolonged, manual participation is reduced, and labor resources are saved.
Description
technical field [0001] The present application relates to the field of computer technology, and more specifically, to a positioning fingerprint updating method, device, storage medium and electronic equipment. Background technique [0002] With the popularization of wireless local area network and people's increasing demand for positioning technology, indoor positioning technology develops rapidly. Indoor positioning technology refers to determining the location of mobile terminals in an indoor environment, and then providing positioning services for users, or performing real-time monitoring and tracking. [0003] Since there is generally no satellite signal indoors, GPS (Global Positioning System, Global Positioning System) cannot play a role in indoor positioning. Therefore, the indoor positioning technology usually utilizes a wireless communication network to accurately determine the geographic location of a certain mobile terminal at a certain time by measuring some par...
