Problems solved by technology
[0004] Since it is implemented with a physical structure, the gimbal itself needs to occupy a certain space, and it cannot be applied to environments with large space restrictions;
[0005] The electric pan / tilt is driven by a motor, and there are hardware bottlenecks in the vibration control and response speed of structural adjustment. If the problem is solved by upgrading the hardware, the cost will inevitably increase significantly;
[0006] During vehicle-mounted video monitoring, if the pan / tilt is controlled to rotate and adjust the angle of view to view the local area, a blind area will be formed for the global angle of view. Once the angle of view blind area fails, video data will be lost, resulting in the system being unable to monitor the area.

The invention discloses a virtual pan-tilt system, comprising an image acquisition unit, wherein, the image acquisition unit performs image acquisition of a global angle of view on a monitoring area;a pan control server communicatively connected with the image acquisition unit, collecting data of the image acquisition unit, and sending an image acquisition control instruction to the image acquisition unit; a remote control terminal which is wirelessly connected with the pan-head control server, sends the image acquisition control instruction and the pan-head control instruction, receives theimage data of the pan-head control server and performs image processing, thereby adjusting the field of view area for display and zooming the displayed image; and a display window for displaying the field-of-view area. Image processing is used to realize the function of simulating electric pan-tilt platform. In the absence of physical pan-tilt platform, the quick direction adjustment of display field area, image zoom and so on can be realized.
Description
technical field [0001] The present invention relates to the technical field of monitoring equipment, in particular to a virtual pan-tilt system. Background technique [0002] The traditional physical gimbal adopts a mechanical transmission structure, and the horizontal rotation and pitch adjustment are performed manually or electrically. [0003] The physical cloud platform in the prior art has the following disadvantages: [0004] Since it is implemented with a physical structure, the gimbal itself needs to occupy a certain space, and it cannot be applied to environments with large space restrictions; [0005] The electric pan / tilt is driven by a motor, and there are hardware bottlenecks in the vibration control and response speed of structural adjustment. If the problem is solved by upgrading the hardware, the cost will inevitably increase significantly; [0006] During vehicle video surveillance, if the pan / tilt is controlled to rotate and adjust the angle of view to vi...
