Embodiment 1

[0030] Figure 1b It is a flow chart of a method for determining positioning accuracy provided by Embodiment 1 of the present invention. The method of this embodiment can be executed by a device for determining positioning accuracy, which can be implemented by means of hardware and / or software, and Generally, it can be integrated in a server for determining the positioning accuracy. The method of this embodiment specifically includes:

[0031] 110. Obtain the positioning result to be verified and the standard positioning result corresponding to the target positioning location.

[0032] In order to measure the positioning accuracy of a positioning technology or positioning product, it is necessary to first obtain the positioning result of the positioning technology or positioning product at a positioning location, and then compare the obtained positioning result with the actual location information of the positioning location. The accuracy of the positioning result can be det...

Embodiment 2

[0049] figure 2 It is a flowchart of a method for determining positioning accuracy provided by Embodiment 2 of the present invention. This embodiment is optimized based on the above-mentioned embodiments. In this embodiment, the target positioning location is specifically optimized as: a positioning location that matches the target positioning scene; and

[0050] The specific optimization of obtaining the positioning results to be verified and the standard positioning results corresponding to the target positioning location is as follows: in the user's historical positioning request log, obtain the scene positioning log that matches the target positioning scene; The first positioning result is used as the positioning result to be verified, and the second positioning result in the target scene positioning log is used as the standard positioning result.

[0051] Correspondingly, the method in this embodiment specifically includes:

[0052] 210. From the historical positioning...

Embodiment 3

[0066] image 3 It is a flowchart of a method for determining positioning accuracy provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, in the user's historical location request log, the specific optimization of obtaining the scene location log that matches the target location scene is: according to the user's historical location request The second positioning result in the log and setting the search radius to generate a scene search area; if the scene search area includes a point of interest matching the target positioning scene, then use the user history positioning request log as the scene localization logs; and

[0067] In the user's historical positioning request log, obtaining the scene positioning log that matches the target positioning scene is also specifically optimized as follows: if the scene search area does not include a point of interest that matches the target posit...

Abstract

The embodiment of the invention discloses a method and apparatus for determining positioning accuracy. The method comprises the steps of: acquiring a positioning result to be verified and a standard positioning result which correspond to a target positioning place; calculating a walking distance between the positioning result to be verified and the standard positioning result; and according to the walking distance, determining accuracy of the positioning result to be verified. According to the the technical scheme adopted by the embodiment of the invention, a method of determining accuracy of a positioning result to be verified according to a linear distance between the positioning result to be verified and a standard positioning result in the prior art is improved; when accuracy of the positioning result is evaluated, actual experience of a user for positioning accuracy is added, and the fuzzy user experience problem can be effectively quantified into the actual walking distance; an existing positioning accuracy determining technology is optimized; reliable basis is provided for improvement and optimization of a positioning technology; and the method and the apparatus are helpful for improving and optimizing a positioning strategy.

Description
