step S14, binding the coordinate information of the target point with the AR stereo graph to form an AR aerial mark information point;

and step S15, sending the AR air mark information point to a second terminal for tracking.

Before step S15, the user may choose to create a general mark, a distress mark or a real-time mark by clicking a button for issuing a mark in the smart mobile device (e.g., a mobile phone) side screen. For the distress mark, the AR aerial mark can penetrate any blocking object, so the method can be applied to field rescue, the trapped person can set the aerial SOS mark, and the rescuers can visually see the AR aerial mark of the trapped person so as to determine the direction.

In some optional embodiments, when forming the AR stereoscopic image, the method further includes: and loading the coordinate information of the target point on the 3D marking pattern.

In some optional embodiments, when forming the AR stereoscopic image, the method further includes: and acquiring the time when the AR stereo graph is formed, and loading the time onto the 3D mark pattern.

The first terminal and the second terminal can interact directly or interact through the server, related functions can be integrated into corresponding apps, different functions are started through different buttons, information points marked in the AR air when SOS is used for asking for help are generally sent to the second terminal through the server, point-to-point transmission is achieved, in alternative implementation modes, broadcasting can be conducted through the server, the server sets a receiving range according to the target point position information of the first terminal, and for example, a user within 3km away from a trapped person can serve as the second terminal to receive the related information.

In a second aspect of the present application, a marker tracking method based on an AR guide is applied to a second terminal for tracking a target point, as shown in fig. 2, the marker tracking method includes:

step S21, acquiring coordinate information of a target point and an AR stereo graph according to an AR aerial mark information point sent by a first terminal for positioning a target;

In this embodiment, after the second terminal opens the App, the gyroscope and GPS information of the terminal are acquired and AR scene initialization is performed: according to data of a gyroscope and a GPS, an AR three-dimensional scene is established by pointing the x axis to the east, pointing the y axis to the opposite direction of gravity and pointing the z axis to the south, and initialization is completed by setting the position of the equipment as a (0, 0, 0) point during starting. After initialization is completed, the second terminal can view the aerial mark erected by the first terminal.

In an alternative embodiment, after the initialization is completed, the terminal may select to view the guide information or the in-air mark through a filter button. When the aerial mark is selected to be checked, the terminal requests the server to acquire the AR aerial mark information which takes the current terminal GPS coordinate as the center and takes a certain distance (the server can be configured) nearby as the radius, that is, as shown in fig. 5, the AR aerial mark information of a plurality of first terminals can be acquired. And then calculating the offset of an x axis and a z axis according to the AR air mark GPS coordinate returned by the server and the current equipment GPS coordinate, calculating the x and z coordinates of an air mark information point according to the offset and the position of the current equipment in the scene, calculating a y coordinate according to the altitude of the air mark returned by the server and the difference between the altitude of the current terminal, and finally placing the AR graph of the air mark at the calculated xyz coordinate position.
