Embodiment 1

[0027] Figure 1a The flow chart of the pan-tilt camera control method provided by Embodiment 1 of the present invention, this embodiment is applicable to the situation of improving the service life of the pan-tilt camera, the method can be executed by the pan-tilt camera control device, and the device can use software and / or or hardware, and can be integrated on the PTZ camera.

[0028] Such as Figure 1a As shown, the PTZ camera control method specifically includes the following processes:

[0029] S101. Determine a clockwise path and a counterclockwise path for the pan / tilt camera to go from the current preset position to the target preset position.

[0030] Among them, the preset positions are used to represent the key areas to be monitored and the operating conditions of the PTZ cameras. The PTZ camera usually pre-sets multiple preset positions, and rotates between each preset position according to the preset route. What needs to be explained here is that during the act...

Embodiment 2

[0046] figure 2 The flow chart of the pan-tilt camera control method provided by the second embodiment of the present invention, this embodiment is optimized on the basis of the above-mentioned embodiments, see figure 2 , the method includes:

[0047] S201. Determine the maximum life load value of a preset position point in the pan / tilt.

[0048] On the basis of the above embodiments, the life load value of each position point can be determined according to the preset ordinate value of the position point, and the maximum life load value can be determined through comparison.

[0049] S202. Determine whether the maximum life load value is equal to or greater than the rotation life threshold of the gimbal, and if so, execute S203-S205.

[0050] In this embodiment, firstly, the total rotational life of the pan / tilt camera is obtained when it rotates along the shortest path, and the total rotational life corresponds to the friction life of the slip ring track and each location ...

Embodiment 3

[0056] image 3 It is a structural schematic diagram of the pan-tilt camera control device in Embodiment 3 of the present invention. This embodiment is applicable to the situation of improving the service life of the pan-tilt camera. See image 3 , the device includes:

[0057] The first path determination module 301 is used to determine the clockwise path and the counterclockwise path of the pan-tilt camera from the current preset position to the target preset position;

[0058] The second path determination module 302 is configured to require life load values ​​of at least two first location points passed by the clockwise path and life load values ​​of at least two second location points passed by the counterclockwise path , selecting a current rotation path from the clockwise path and the counterclockwise path;

[0059] The rotation control module 303 is configured to control the PTZ camera to rotate from the current preset position to the target preset position according...

Abstract

The embodiment of the present invention discloses a pan-tilt camera control method and device, a pan-tilt camera and a storage medium. The method includes: determining a clockwise path and a counterclockwise path of the pan-tilt camera from a current preset position to a target preset position; Select the current rotation from the clockwise path and the counterclockwise path based on the life load values ​​of at least two first location points that the clockwise path needs to pass through, and the life load values ​​of at least two second location points that the counterclockwise path needs to pass through Path: control the PTZ camera to rotate from the current preset position to the target preset position according to the current rotation path. The embodiment of the present invention determines the current rotation path according to the life load values ​​of the position points in the clockwise path and the counterclockwise path, so that after rotating according to the current rotation path, the life load values ​​of each position point passed by the pan / tilt camera are balanced, thereby ensuring The slip ring and cables of the pan / tilt camera wear evenly, which improves the rotation life of the pan / tilt camera.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of security monitoring, and in particular to a method and device for controlling a pan-tilt camera, a pan-tilt camera, and a storage medium. Background technique [0002] In the field of security monitoring, PTZ cameras have been widely used. Compared with ordinary cameras, the biggest difference between PTZ cameras is that they can rotate freely up, down, left, and right. The current PTZ cameras generally have the function of 360° unlimited rotation. In order to avoid the camera winding during the rotation process and achieve the unimpeded transmission of interactive information, the PTZ cameras are equipped with a rotating communication device, that is, a slip ring. The slip ring is installed on the rotation center of the pan-tilt camera, connecting the two parts of the pan-tilt camera, the rotating part and the stationary part, and plays the role of information transmission. [000...
