Description

Technical Field

[0001] The utility model relates to the technical field of camera movement, and more particularly to a mobile device for a camera in a broadcasting and television center. Background Art

[0002] A mobile device for broadcast and television center cameras. A high-precision, multi-functional camera moving system designed specifically for broadcast and television production environments.

[0003] In the existing technology, firstly, some devices cannot adjust the camera height according to the shooting requirements, and it is difficult to adapt to the requirements of different scenes and shooting angles. Additional tools or equipment are needed to change the camera height. Some high-angle or low-angle shooting is difficult to achieve. Every time the height needs to be changed, the entire equipment may need to be rebuilt or adjusted. Secondly, the camera of some devices cannot be rotated flexibly, and it is difficult to capture images in different directions. It is impossible to achieve all-round and multi-angle shooting. The entire device needs to be moved to change the shooting angle. Manual adjustment may cause the picture to shake or be unstable, and it is difficult to achieve smooth camera movement and rotation. Finally, some devices require more time and tools to replace or adjust the camera, and cannot quickly respond to changes in on-site shooting needs. It is difficult to quickly install the camera in different locations. The shooting quality and equipment safety may be affected due to loose fixation, and the daily inspection and maintenance of the equipment become more complicated. Utility Model Content
