Problems solved by technology

[0004] However, the positioning technology used in the first method has its own errors. Even the most accurate GPS technology has a very large error in places covered by tall buildings; and this method can only obtain the user's physical location, but cannot accurately Identify the target audience that the user is interested in
The second method only relies on image information to achieve low target recognition accuracy; and the retrieval calculation complexity based on image content is relatively high, which consumes more computing and storage resources for smart terminals, and the response delay is also relatively large; In addition, it is necessary to use special equipment (such as street view cars) to obtain location image data when establishing a location image database, which is costly and difficult to achieve automatic update

Embodiment 1

[0052] In order to solve the problems existing in the background technology, the embodiment of the present invention provides a position information acquisition method, which is applied to a position information acquisition device, and the position information acquisition device can be implemented as a terminal or a server; the functions realized by the position information acquisition method It can be implemented by the processor in the location information acquisition device calling the program code, of course the program code can be stored in the memory, it can be seen that the location information acquisition device at least includes a processor and a memory.

[0053] image 3 It is a schematic diagram of the implementation flow of Embodiment 1 of the present invention, such as image 3 As shown, the location information acquisition method includes:

[0054] Step S301, acquiring fingerprint information of a target object.

[0055] Here, the fingerprint information includ...

Embodiment 2

[0073] Based on the foregoing first embodiment, the embodiment of the present invention provides a location information acquisition method, which is applied to the terminal side. The functions implemented by the location information acquisition method can control the camera module and the sensor module through the processor in the terminal calling the program code. , a positioning module, of course, the program code can be stored in a computer storage medium, it can be seen that the terminal at least includes a processor, a camera module, a sensing module, a positioning module and a memory.

[0074] Figure 4 It is a schematic diagram of the implementation flow of the method for obtaining location information in Embodiment 2 of the present invention, as shown in Figure 4 As shown, the location information acquisition method includes:

[0075] Step S401, the terminal collects sample information of a target object.

[0076] Here, the sample information includes image informatio...

Embodiment 3

[0087] Based on the above-mentioned embodiments, the embodiment of the present invention provides a location information acquisition method, and the location information acquisition device is taken as an example for illustration, as shown in Figure 5 As shown, the location information acquisition method includes:

[0088] Step S501, the server builds a fingerprint database.

[0089] Here, the server needs to construct (or establish) a fingerprint database first, and the identification information of each object in each grid area is correspondingly stored in the fingerprint database, wherein each object corresponds to at least one set of fingerprint information; that is, a fingerprint information corresponds to one piece of identification information, and one piece of identification information corresponds to at least one set of fingerprint information.

[0090] In other embodiments of the present invention, constructing (or establishing) the fingerprint database mainly inclu...

Abstract

The invention discloses a location information acquisition method, device and equipment. The method comprises the steps that fingerprint information of a target object is acquired, wherein the fingerprint information at least comprises azimuth information of the object; the fingerprint information of the target object is compared with fingerprint information of all pre-stored objects, and identification information of a matching object corresponding to the target object is obtained; location information of the matching object is determined according to the identification information of the matching object; and the location information of the matching object is output.

Description

technical field [0001] The present invention relates to positioning technology, in particular to a method, device and equipment for acquiring position information. Background technique [0002] With the rapid development of communication networks and the wide application of smart terminals, location-based services are being accepted by more and more users under the strong promotion of the mobile Internet. Users have become accustomed to using smart terminals to view surrounding maps and locate target objects and navigation. [0003] At present, there are two types of location-based positioning services provided on smart terminals. One is based on positioning technologies such as Global Positioning System (Global Positioning System, GPS), Wireless Fidelity (WiFi) network positioning, and communication base station positioning. , the smart terminal first obtains the user's physical location based on the above positioning technology, and then returns geographical information (...
