Problems solved by technology
The problems of this type of device are: 1. The price of the physical support and other instruments is too high; 2. The calibration work is very cumbersome; 3. The stability of the physical support is poor; 4. The projection wall has poor mobility
[0005] In addition, the most important point is that most of the large screens spliced by the current projectors are flat, and there is no mature parallel drawing image display curved large screen splicing device

Embodiment Construction
[0022] Such as figure 1 , 2 As shown, the splicing device for large-screen projectors with curved surfaces is drawn in parallel, including some horizontal displacement rods, some vertical displacement rods, some cross displacement frames, some projector brackets, some projector boxes and some projectors, and the cross displacement frames are composed of The two hollow rods are fixed and assembled in a cross shape. The horizontal displacement rod and the vertical displacement rod respectively pass through the horizontal and vertical hollow rods of the cross displacement frame. The projector bracket is fixedly connected with the cross displacement frame. In the projector box, the projector bracket and the projector box are connected up and down in series through a grooved rotating rod integrated up and down.
[0023] The fixing method of the two hollow rods of the cross displacement frame is welding, and the length of the hollow rods is between 15-35mm. This is because the pro...

The invention discloses a parallel-rendering image display curved-surface large-screen projector splicing device. According to the invention, a large screen formed by the splicing of projectors is a curved surface, and is low in cost, convenient to correct and high in stability. The device comprises a plurality of horizontal displacement rods, a plurality of vertical displacement rods, a pluralityof cross-shaped displacement frames, a plurality of projector supports, a plurality of projector boxes and a plurality of projectors. Each cross-shaped displacement frame is formed by fixedly assembling two hollow rods in a cross-shaped mode. The horizontal displacement rods and the vertical displacement rods penetrate through the horizontal and vertical hollow rods of the cross-shaped displacement frames respectively. The projector supports are fixedly connected with the cross-shaped displacement frames. The projectors are arranged in the projector boxes. The projector supports and the projector boxes are connected in series up and down through grooved rotating rods which are connected into a whole. The rotating rods are adjusted, so that the projection angles of projectors connected with the same rotating rod is changed. In cooperation with a curved-surface projection curtain, a curved-surface large screen can be projected. The device is low in production cost, stable in correctionand high in projection wall moving flexibility.
Description
technical field [0001] The invention relates to the technical field of displays, in particular to the technical field of large-screen projector splicing display devices for computer parallel rendering. Background technique [0002] With the development of parallel rendering technology and the improvement of computer 3D scene rendering performance, the backwardness of 2D display technology becomes more obvious. Although the development of computer hardware is very fast, various display terminals, such as various technical indicators of computer monitors, have been progressing slowly. The backward display technology development has seriously affected the progress of computers brought about by other hardware improvements. How to display the video content input by high resolution and multiple pipelines is a problem that continues to be solved. [0003] Computer-drawn images displayed in parallel are typical of such problems. A more common solution is to splice multiple project...
