Problems solved by technology

Since the camera is usually deployed outdoors and the outdoor environment is complex, long-term wind blowing may cause the camera to rotate in a certain direction, or the camera may be removed and reinstalled, which may also cause the camera to rotate relative to the original coordinate system
At this time, if the camera originally added a large number of augmented reality tags, when the camera rotates in situ due to external factors, the position of the tags will not correspond to the actual position.
For the above problems, there are two existing solutions. The first is to delete the label and add it again. The second is to manually restore the camera to the original coordinate system. However, no matter which method is mentioned above, the operation is cumbersome. resulting in inefficiency in restoring the original coordinates

Embodiment 1

[0040] see figure 1 , figure 1 It is a flowchart of a video adjustment method provided by an embodiment of the present invention; including:

[0041] S1. Obtain the initial coordinates of the label;

[0042] S2. Move the current label to a preset target position;

[0043] S3. Obtain the target coordinates of the target position, and calculate the difference between the initial coordinates of the current tag and the target coordinates of the target position;

[0044] S4. Add the initial coordinates of other tags to the difference to obtain the target coordinates of the other tags;

[0045] S5. Moving the other tags according to the target coordinates of the other tags.

[0046] It is worth noting that the video adjustment method described in the embodiment of the present invention can be implemented by a client, the client includes a display screen, the client communicates with the camera, and is used to obtain the video captured by the camera, and convert the video to dis...

Embodiment 2

[0060] see Figure 7 , Figure 7 It is a schematic structural diagram of a video tag adjustment system 10 provided by an embodiment of the present invention; it includes:

[0061] The coordinate acquisition module 11 is used to acquire the initial coordinates of the label; it is also used to acquire the target coordinates of the preset target position;

[0062] The calculation module 12 is used to calculate the difference between the initial coordinates of the current label and the target coordinates of the target position; it is also used to add the initial coordinates of other labels to the difference to obtain the target coordinates of the other labels ;

[0063] The moving module 13 is configured to move the current tag to the target position; and is also configured to move the other tags according to the target coordinates of the other tags.

[0064] It is worth noting that the video tag adjustment system 10 described in the embodiment of the present invention may be a...

Embodiment 3

[0075] see Figure 8 , Figure 8 It is a schematic structural diagram of a video tag adjustment device 20 provided by an embodiment of the present invention; the video tag adjustment device 20 of this embodiment includes: a processor 21, a memory 22, and stored in the memory 22 and can be used in the processor 21 computer program running on it. When the processor 21 executes the computer program, the steps in the embodiment of the above-mentioned video adjustment method are implemented, for example figure 1 Steps S1-S5 are shown. Alternatively, when the processor 21 executes the computer program, it realizes the functions of each module / unit in the above-mentioned device embodiments, for example, the coordinate acquisition module 11 .

[0076] Exemplarily, the computer program can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 22 and executed by the processor 21 to complete this invention. The one or more modules / unit...

Abstract

The invention discloses a video tag adjusting method, which is characterized by comprising the following steps: obtaining an initial coordinate of a tag; moving the current label to a preset target position; obtaining a target coordinate of the target position, and calculating a difference value between the initial coordinate and the target coordinate; adding the initial coordinates of the other tags and the difference value to obtain target coordinates of the other tags; and moving the other tags according to the target coordinates of the other tags. The invention further discloses a video tag adjusting system and video tag adjusting equipment. By adopting the embodiment of the invention, the operation is simple and convenient, and the existing tags in the video can be effectively in one-to-one correspondence with the actual positions when the camera rotates.

Description

technical field [0001] The present invention relates to the field of augmented reality camera display, in particular to a video label adjustment method, system and equipment. Background technique [0002] Today, the technology of superimposing augmented reality labels on camera video is expanding in the security field. Since the camera is usually deployed outdoors and the outdoor environment is complex, long-term wind blowing may cause the camera to rotate in a certain direction, or the camera may be removed and reinstalled, which may also cause the camera to rotate relative to the original coordinate system. At this time, if the camera originally added a large number of augmented reality tags, when the camera rotates in situ due to external factors, the positions of the tags will not correspond to the actual positions. For the above problems, there are two existing solutions. The first is to delete the label and add it again. The second is to manually restore the camera to...
