Example Embodiment

[0061] The present invention will be described in detail below in conjunction with the drawings:

[0062] Such as figure 1 As shown, the present invention provides a method for target positioning based on a mobile terminal, which includes the following steps:

[0063] S1, calculating the distance between the target object and the mobile terminal based on the photographic ranging principle;

[0064] S2: Acquire location information of the mobile terminal and position information of the target object relative to the mobile terminal;

[0065] Wherein, the location information of the mobile terminal is acquired through a positioning device configured by the mobile terminal itself. The positioning device may be a GPS positioning device.

[0066] Obtaining the position information of the target object relative to the mobile terminal can be obtained through the direction sensor configured by the mobile terminal itself. However, in practical applications, due to the interference of various out...

Abstract

The invention provides a method of conducting target location based on a mobile terminal. The method comprises the following steps: S1. figuring and getting distance between a target object and the mobile terminal based on a photography distance measure principle, S2. obtaining location information of the mobile terminal and azimuth information of the target object relative to the mobile terminal, S3. and locating location information of the target object by combining the distance between the target object and the mobile terminal with the location information of the mobile terminal and the azimuth information of the target object relative to the mobile terminal, wherein the distance between the target object and the mobile terminal is achieved from step S1 and the location information of the mobile terminal and the azimuth information of the target object relative to the mobile terminal are achieved from step S2. Positioning of the target object is achieved fast, timely, accurately and simply.

Description

technical field [0001] The invention belongs to the technical field of target positioning, and in particular relates to a method for target positioning based on a mobile terminal. Background technique [0002] In recent years, the popularity of smart phones has spawned a series of location-related application services, such as route navigation, location marking, restaurant, hotel and entertainment recommendation, etc. In the above-mentioned various applications, the query method based on its own location is usually used to provide services; that is, the user first uses the positioning system on the smart phone to locate his own location, obtains the location information of his own location, and then uses the The location information is sent to the service provider with a query question attached, wherein the specific query question can be "what are the restaurants around?", "how to get to the airport from here?". When the service provider receives the query information provi...
