Problems solved by technology

[0003] In the above method, the mobile terminal needs to be located within the range of the target. When the distance between the mobile terminal and the target is relatively large and the mobile terminal is not within the range of the target, the position of the mobile terminal cannot be used as the position of the target. Here In this case, it will not be possible to determine the location of the target

Embodiment 1

[0058] Aiming at the problems existing in the prior art, Embodiment 1 of the present invention proposes a method for locating a target based on non-visual perception information. The method can be applied to a mobile terminal equipped with a camera, and the position of the target can be located through the mobile terminal. In the above application scenarios, such as figure 1 As shown, the target location method based on non-visual perception information includes the following steps:

[0059] Step 101, the mobile terminal obtains acceleration information when it moves from a first location to a second location, and uses the acceleration information to calculate a distance between the first location and the second location.

[0060] Wherein, the acceleration information when moving from the first position to the second position may specifically include, but not limited to, acceleration values ​​at multiple time points when moving from the first position to the second position. ...

Embodiment 2

[0090] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a mobile terminal for target positioning based on non-visual perception information, the mobile terminal is provided with a camera, such as figure 2 As shown, the mobile terminal specifically includes:

[0091] An obtaining module 11, configured to obtain acceleration information when the self moves from the first position to the second position;

[0092] A calculation module 12, configured to use the acceleration information to calculate the distance between the first position and the second position; use the distance between the first position and the second position, and the mobile terminal In the first position and the second position respectively, when the camera is aiming at the target, the angle between the aiming direction of the camera and the vertical direction of the ground is used to calculate the distance information between the second position and...

Abstract

The embodiment of the invention discloses a target locating method and device based on non-visual perception information. The method comprises the following steps: acquiring the acceleration information of a mobile terminal from a first position to a second position; calculating the distance between the first position and the second position according to the acceleration; calculating the distance information between the second position and a target according to the distance between the first position and the second position, and the included angle between the aiming direction of a camera and a direction perpendicular to the ground when the mobile terminal is at the first position or the second position and the camera is aimed at the target; calculating the longitude / latitude information of the target according to the distance between second position and the target, the included angle between the aiming direction of the camera and a real north direction, and the longitude / latitude information of the second position. The target locating method and device have the advantages that the position of the target can be determined accurately without dependence on the picture processing and computer vision algorithm, and imaging quality.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a target positioning method and device based on non-visual perception information. Background technique [0002] At present, the use of mobile terminals has been rapidly popularized, and there are more and more location-related applications on mobile terminals, such as location labeling, pollution event location, navigation, location-based social applications, restaurant recommendations, etc. In location-related applications, the mobile terminal needs to be within the range of the target, and the position of the mobile terminal is determined by means of satellite positioning and base station positioning, and the position of the mobile terminal is taken as the position of the target. For example, in the location of a pollution event, when the mobile terminal is within the range of the target of the pollution event (that is, the location where the pollution event o...
