Position fingerprint identification location method

Abstract

The invention relates to a position fingerprint recognize positioning method, wherein it comprises: fixing positioning area, auxiliary area, and relative names, ranges, and extracting the position fingerprint characters, recognizing positioning, training or retraining; the auxiliary area is outside, inside the positioning area or between it and positioning area; the positioning area is set at the position needed high-accuracy position; the auxiliary area is set at the part without high-accuracy position but affected by the positioning area; the positioning and auxiliary areas can be increased or decreased; the position fingerprint data can be downloaded, uploaded or transmitted; the invention can avoid building large position fingerprint database, and user can accurately position at any place, to realize high-accuracy self positioning at high, middle and low movable terminals, to protect personality, without high cost. And the invention can be based on network or third part positioning, to realize positioning at large range at common accuracy and positioning at special position with high accuracy.

Description

technical field [0001] The invention relates to mobile terminal positioning, in particular to a radio positioning method for radio propagation environment and pattern recognition. Background technique [0002] Radiolocation is divided into satellite radiolocation and terrestrial radiolocation. Satellite radio positioning uses multiple satellites to realize mobile terminal positioning, and ground radio positioning realizes mobile terminal positioning by measuring parameters such as the propagation time, time difference, signal strength, phase or incident angle of radio waves from the transmitter to the receiver. [0003] GPS positioning accuracy is high, but the mobile terminal needs to be equipped with GPS function, the cost is high, the power consumption is large, and the volume is large. Generally, it is required to receive at least 4 satellite positioning signals. In dense urban areas between tall buildings, inside buildings and in any area where fewer than 4 satellites ...

Problems solved by technology

[0011] In order to solve the above technical problems existing in the existing positioning methods, the present invention provides a position fingerprint identification and positioning method, which does not need to establish a huge position fingerprint database, and the user can position with high precision anytime, anywhere, that is, learning (training). Use; the location fingerprint features are retrained while the mobile terminal is positioned to realize the update of the location fingerprint features without additional maintenance; the user can specify the positioning range or accuracy according to the needs; realize the independent positioning of the mobile terminal, especially in high, medium and low All grades of mobile terminals realize independent positioning, which can effectively protect user privacy, basically do not increase the cost of mobile terminals, and do not need to pay daily positioning fees; it can also be used for network-based or third-party positioning
