Problems solved by technology

[0005] The defect of this current method is that if there is a major change in the indoor wifi, for example, a major adjustment occurs to the equipment that provides the wireless signal, and one or more merchants that provide the wifi signal migrate from place a of the mall to place b of the mall. The fingerprint information of the unknown non-reference point that is very close to the reference point after the change is actually quite different from the fingerprint information of the original reference point, but because the current method still determines the non-reference point and The mapping relationship between reference points lacks the verification of the location of non-reference points, so that the fingerprint data of non-reference points cannot be accurately determined

Abstract

The invention provides an automatic update method and an automatic update device for indoor wireless signal fingerprint data. The automatic update method comprises the following steps of acquiring a track of a moving object in an indoor moving process and recording information of a wireless signal received by the moving object in the indoor moving process; extracting a first track from the track according to a predetermined rule; acquiring absolute position information of the first track based on matching between the first track and an indoor map; and updating the original indoor wireless fingerprint data based on the wireless signal information and the absolute position information of the first track. Based on the method and the device provided by the embodiment of the invention, accuracy of the updated indoor wireless signal fingerprint data can be effectively enhanced.

Description

Technical field [0001] The present application relates to wireless networks, and in particular relates to a method and apparatus for automatically updating an indoor radio fingerprint data signal. Background technique [0002] Indoor wireless data signal typically comprises a fingerprint characterizing the position information of the respective chamber reference point of the received wireless reception signal type, strength, the position of a point (e.g., latitude and longitude coordinates) and other data, by using the signal strength of the fingerprint data and location information can provide location-based services to users. [0003] Since the interior provide wireless signal is not static, for example, in shopping malls, wifi signal may provide different business today is 100, the next offer businesses different wifi signal is increased to 150, the position of each point in the mall received wireless signal type and strength will change, so the indoor wireless signals need to...
