Positioning method and positioning device

Abstract

The invention discloses a positioning method and a positioning device. The positioning method includes the steps: a user location information acquisition step of acquiring location information of a user in a known environment coordinate system; a gaze distance detection step of detecting a distance of a user current gaze point relative to the user; a gaze direction acquisition step of acquiring a direction of the gaze point relative to the user in the environment coordinate system; a location acquisition step of obtaining location information of a user observed object in the environment coordinate system according to the location information of the user in the environment coordinate system, the distance of the gaze point relative to the user and the direction of the gaze point relative to the user in the environment coordinate system. The positioning method and the positioning device allow the user to know the location information of the watched object by watching the object, are quite convenient, also can accurately designate a to-be-positioned object, thereby having higher positioning precision.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method and device. Background technique [0002] In daily life, there are often problems with the positioning of specified objects. For example, when you see a building in the distance while traveling, you hope to get its location information so that you can further inquire about more relevant information; measure the distance between two specified objects in the distance; Specify the location of an object to learn about its properties, functions, and more. [0003] In some solutions, the specified object can be located by means of image acquisition, for example, taking an image of a specified object (such as a building) in the distance and uploading it to the remote end. The images stored in the database are compared and analyzed to find a stored image that matches the uploaded image, and the information (including location information) corresponding t...

Problems solved by technology

However, this method has the following problems: when there are multiple images in the database that match the uploaded images, it is possible to get wrong information; in addition, if there is no image corresponding to the captured image stored in the database, it is impossible to determine the corresponding image. Information corresponding to the captured image

This method is completed by taking pictures with a mobile phone. In this method, the focus point of the camera module needs to be accurately placed on the object whose location information needs to be obtained, otherwise the information obtained will have a large error, but in many cases (such as the texture of the object being photographed) In the case that it is not obvious), there is no guarantee that the focus point can accurately fall on the object. In addition, this method is not intuitive and convenient for users to use.
