Description

TECHNICAL FIELD

[0001] The utility model relates to the field of green screen technology for shooting, and particularly relates to a green screen hanging device for shooting. BACKGROUND

[0002] Green screen shooting is a technique used in film and video production, and its core concept is to use a specific monochromatic background (usually green or blue) to create a replaceable background for actors or objects during shooting. The green screen background refers to a piece of single-color cloth or wall, usually bright green. The reason for choosing green is that it contrasts sharply with human skin color and is easy to distinguish between foreground and background in post-production. In post-production, the chroma key technique is a color-based compositing method that removes the green screen background from the video by identifying its chroma value, making it transparent, and thus replacing it with any other background.

[0003] The patent document with the application number CN202322364639.5 discloses a green screen hanging device for shooting, which includes a bearing base. The bearing base is provided with a stabilizing assembly around the bottom. The stabilizing assembly includes a hydraulic chamber, which is provided with a hydraulic cylinder inside. The hydraulic cylinder is provided with a support foot at the bottom and on the bearing base. The bearing base is provided with a lifting assembly on both sides of the top. After moving the whole device to the designated location by the stabilizing assembly on the universal wheel, the support foot is lifted out of the ground by the hydraulic cylinder, and the stability of the bearing base is enhanced, thereby stabilizing the whole device. Compared with the existing green screen hanging device for shooting, the utility model can improve the overall protection, functionality, and practicality of the green screen hanging device for shooting. Based on the above patent search and combined with the existing green screen hanging device for shooting in the prior art, it is found that the existing green screen hanging device for shooting often uses a simple bracket to hang the green screen, which is too simple and has low practicality. In particular, there are scenes such as building exterior wall shooting and actor wall-walking in some video content. However, the existing green screen hanging device for shooting cannot meet these requirements and often only pastes the green screen on the exterior wall, which is time-consuming and laborious.
