Embodiment 1

[0018] figure 2 It is a flow chart showing the evaluation method of the positioning result in Embodiment 1 of the present invention. The method may be performed on a server such as a location service. The method comprises the steps of:

[0019] Step 101: Acquire location logs.

[0020] Specifically, one location log can be obtained from each machine or several machines are randomly selected in each computer room, and one location log can be obtained from each machine to ensure data diversity.

[0021] For example, the obtained location log sample is as follows: NOTICE:10-17 18:24:33:loc*18631[logid:2416100588][proctime:][reqsvr:][cmdno:][svrna me:][errno:] [][][reqip:127.0.0.1][imei:y__.|0]query[&ll=103.85615|13.36266&cl=456|6|3021|169094&cu=Raaz7lqFyep2gcNzH7YLDf5tDqi-dpQoptvu8XMdUl-1o4szMumEeWwhvafS|rgHdxSh9REKx0R73QBtF6t7IEejwUz3cLErC|0&wf=e4d332cfcc9a;65; |08bd43865d6a;67;|72c714534178;70;|0c722c1ec856;70;]result[{point":{"x":"103.857725","y":"13.361216"}}].

Embodiment 2

[0035] Figure 6It is a logic block diagram showing the evaluation device of the positioning result in Embodiment 2 of the present invention. refer to Figure 6 The evaluation device for the positioning result includes a positioning log acquisition module 201 , a positioning evaluation data extraction module 202 , a communication positioning data acquisition module 203 and an evaluation result generation module 204 .

[0036] The location log obtaining module 201 is used to obtain the location log.

[0037] The positioning evaluation data extraction module 202 is used for extracting GPS positioning data and positioning scan data from the positioning log. Specifically, the positioning scan data may include wifi scan data and / or base station scan data.

[0038] The communication positioning data acquisition module 203 is used for acquiring communication positioning data from an offline database through a positioning strategy according to the positioning scan data.

Abstract

The embodiment of the invention provides a method and a device for evaluating positioning results. The method comprises the following steps: obtaining a positioning log; extracting GPS positioning data and positioning and scanning data from the positioning log; acquiring communicating and positioning data from an off-line database by virtue of a positioning strategy according to the positioning and scanning data, wherein the off-line database comprises preset standard positioning data; comparing the communicating and positioning data with the GPS positioning data according to evaluation indexes to obtain an evaluation result. By virtue of the method and the device for evaluating the positioning results of the embodiment of the invention, positioning service which is not on-line in an off-line manner, so that a novel positioning service result is compared with an old positioning service result; meanwhile, the risk of low effect after the positioning service is on-line is reduced.

Description

technical field [0001] The present invention relates to the technical field of positioning processing, in particular to a positioning result evaluation method and device. Background technique [0002] With the rapid development of science and technology, people pay more and more attention to location-based services, which are widely used in intelligent transportation, emergency rescue, property monitoring, etc., and the basis for providing these services is location technology. [0003] At present, positioning technology can be divided into positioning technology based on GPS, positioning technology based on wifi and positioning technology based on mobile cellular network. Existing positioning services are all implemented based on the above-mentioned positioning technologies. However, the new version of the positioning service can only know whether its positioning effect is good or bad after it goes online, which makes the risk of poor effect after going online higher. Con...
