Embodiment 1

[0053] Embodiments of the present invention provide a positioning method, specifically, refer to figure 2 As shown, the positioning method includes the following steps S11 to S12.

[0054] S11. Obtain the system date of the terminal device and the system time of the terminal device, and obtain the height of the target object, the length of the target projection, and the sun direction angle through the image acquisition system of the terminal device.

[0055] Wherein, the target object is perpendicular to the horizontal plane, the target projection is the projection of the target object on the horizontal plane under sunlight, and the sun direction angle is the reverse extension of the clockwise direction from the north direction to the target projection The angle of the line.

[0056] The implementation of obtaining the height of the target object, the length of the target projection, and the sun direction angle through the image acquisition system of the terminal device in t...

Embodiment 2

[0108] Embodiments of the present invention provide a positioning method, specifically, refer to Figure 4 As shown, the positioning method includes the following steps S41 to S45.

[0109] S41. Receive a first operation input by a user.

[0110] Specifically, the first operation may be a click operation on an application logo displayed on the screen of the terminal device for triggering positioning, or an operation for pressing a physical button on the terminal device, or a voice input by the user. commands, or specific gestures entered by the user.

[0111] In some embodiments of the present invention, the specific gesture may be any one of a single-click gesture, a slide gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture, and a double-click gesture.

[0112] S42. In response to the first operation, display a fitting line passing through the focus of the target camera on the shooting preview interface of the termin...

Abstract

The embodiment of the invention provides a positioning method and terminal equipment, and relates to the technical field of communication. The positioning method and the terminal equipment are used for solving the problem that when the terminal equipment is located at a relatively poor network environment, the terminal equipment cannot be positioned through a positioning mode in the prior art. Themethod comprises the steps that the system date of the terminal equipment and the system time of the terminal equipment are acquired, and the height of a target object, the length of a target projection and the sun direction angle are acquired through an image acquisition system of the terminal equipment, wherein the target object is perpendicular to the horizontal plane, the target projection isthe projection of the target object on the horizontal plane in the sunlight, and the sun direction angle is the angle between the north direction and the reverse extension line of the target projection in the clockwise direction; according to the system date, the system time of the terminal equipment, the height of the target object, the length of the target projection and the sun direction angle, the longitude and latitude of the position where the target object is located are calculated.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a positioning method and terminal equipment. Background technique [0002] Among the services provided by terminal devices to users, many services rely heavily on the positioning of the geographical location of the terminal device. For example, in the process of navigating through the terminal device, it is necessary to obtain the geographical location of the terminal device in real time, and another example: ordering takeaway through the terminal device , it is necessary to obtain the geographic location of the terminal device first, so as to filter merchants within the delivery range, so the positioning function of the terminal device is a very important function. [0003] Currently, positioning methods of terminal devices mainly include: Global Positioning System (Global Positioning System, GPS) positioning and network positioning. Among them, GPS positioning ...
