Method of conducting target location based on mobile terminal

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...

Problems solved by technology

[0006] However, there are many shortcomings in the positioning of target objects based on computer vision technology. First, this technology requires users to take pictures of target objects from different positions, which increases the burden on users and brings inconvenience to users; secondly, through a large number of The three-dimensional reconstruction of the object's outline from the object photo will bring a large amount of calculation and a long time delay, and this high calculation cost and delay prevent the popularization of this method in practical application systems
