Embodiment 1

[0055] like figure 2 As shown, a method for automatically verifying the accuracy of indoor position fingerprint positioning includes the following steps:

[0056] S1: When the server receives the positioning request of the positioning user, and according to the current location fingerprint sent by the positioning user (the present invention adopts the RSSI vector f i ) to calculate the estimated position l i After that, to verify l i accuracy, which will f i Sent to the client and activates the veracity detection algorithm. (according to the original fingerprint database to calculate and locate the user's real-time location)

[0057] S2: When the client receives the RSSI vector f sent by the server i Finally, start the terminal motion state detection algorithm to make a judgment on the motion state of the terminals held by all the perceived users participating in the positioning accuracy verification. When the terminal is in a static state and the duration exceeds the pr...

Abstract

The invention relates to the field of WiFi positioning, in particular to a method and device for automatically verifying the accuracy of indoor position fingerprint positioning. The present invention compares the similarity between the location fingerprints at four adjacent reference points of the user's estimated location acquired by the location fingerprint positioning method and the accurate peripheral location fingerprint point set of the user at the current moment, thereby judging the location at this time. Whether the estimated location is accurate and whether the location fingerprint library needs to be updated, and the method proposed in the present invention does not require the user to participate in the judgment subjectively, and thus avoids the uncertainty and subjective error caused by the user's participation. By adding mobile group intelligence tasks, the comparison The peripheral position fingerprint point set is more accurate, which effectively improves the accuracy of the present invention, and simultaneously simplifies the algorithm of accuracy detection, reduces the complexity of calculation, and further reduces the verification time.

Description

technical field [0001] The invention relates to the field of WiFi positioning, in particular to a method and device for automatically verifying the accuracy of indoor position fingerprint positioning. Background technique [0002] In recent years, thanks to the popularization of WLAN and the improvement of the performance of smart phones, the indoor positioning technology based on location fingerprinting method has gradually come to the fore. Since the indoor positioning technology based on WLAN and location fingerprint is compatible with most existing network facilities, it does not need prior information of the specific location of the access point and additional measurement equipment, and the signal measurement is simple to implement, and enables users to enjoy location-based services , maintaining high privacy, and thus widely used in various indoor positioning systems. [0003] When the access point is deployed in the positioning area for a long time, its RSSI (Receive...
