Problems solved by technology

[0006] Using the existing clutter signal data verification method, when the comparison results of the two sets of data (learning data and verification data) are inconsistent, it is impossible to determine whether it is caused by the poor quality of the learning data or the verification data. At the same time, the acquisition personnel can also Find the weakness of the clutter signal collection method and intentionally cheat. For example, the collection personnel can collect once as learning data in the same wrong position, and collect the second time as verification data. However, this cheating method is based on the existing verification method. Cannot be detected effectively, resulting in serious systematic positioning errors

Abstract

The invention discloses a method and device for verifying a spatial clutter signal. The method includes: acquiring at least two spatial clutter signals with position identification information collected at the same target position; point at least two of the spatial clutter signals collected and their location identification information, and determine the signal authenticity of at least two of the at least two spatial clutter signals. It can be seen that the present invention can determine the authenticity of multiple spatial clutter signals by verifying the spatial clutter information and location identification information collected at the same target location point, so that the multiple spatial clutter signals collected at the same target location point Signals are verified. Compared with the previous comparison verification method, the verification scheme in the present invention can effectively locate the wrong clutter signal, and at the same time will not be disturbed by cheating data collection, thus achieving good verification As a result, the efficiency of verification and the authenticity and effectiveness of signals are greatly improved.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, and in particular, to a method and device for verifying space clutter signals. Background technique [0002] The current popular indoor positioning technology is usually completed through the following two stages: [0003] 1. Offline learning. By offline collection of indoor space clutter signals with location tags as fingerprints, a mathematical model of indoor signal field strength is established. [0004] 2. Online positioning. The purpose of positioning is achieved by comparing the clutter signal collected in the positioning request with the fingerprint signal of the mobile phone in the fingerprint database. [0005] However, how to quickly and efficiently verify the quality of clutter signals collected in different ways is a difficult problem that needs to be solved urgently in this field. At present, a common method in this field is to independently collect another set of dat...
