Problems solved by technology

Although high-end projectors with built-in seamless splicing technology achieve good display effects, their disadvantages are: the cost is too high, which restricts a large number of applications in the market; in addition, sophisticated high-end equipment is accompanied by complicated operation and debugging process, the debugging time is also longer
The disadvantage of this method is that once the display environment changes, or the display location needs to be changed, it is necessary to re-do the relevant processing work on the playback source, so it creates great difficulties for the maintenance and update of the system

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the drawings.

[0022] As shown in Figure 1 and Figure 2, the present invention combines multiple small screens with independent projection equipment into a large screen, and projects them on irregular screens such as arc screens, ring screens, dome screens, hyperboloid screens, etc., and through the computer Software processing to realize synchronous playback of the overall picture. The present invention is composed of multiple ordinary PCs, multiple ordinary projectors, and a camera. The graphics accelerator card of the PC as the playback end is connected to one projector, and the other PC is used as the control end to perform operations on the playback end through the local area network. Synchronous control, a camera is connected to the image capture card of the control PC to capture screen images.

[0023] The present invention adopts the client / server (C / S) mode to compose ordinary PCs into a loc...

Abstract

This invention relates to one multi-screen play simultaneous control method for irregular screen, which comprises the following steps: adopting Bezier net grid to process deformation on the picture to fit the projection to irregular screen; then through control end for collection and process on multi-screen picture to fulfill deformation correction; finally processing edge melting; in playing process, through control end processing multi-screen simultaneous control.

Description

Technical field [0001] The invention relates to multi-screen display and control, in particular to a multi-screen playback synchronization control method suitable for irregular screens. Background technique [0002] Among the display and control technologies based on splicing, the seamless splicing technology used to achieve seamless fusion display of images is one of the important technologies. Seamless splicing technology is a special and relatively demanding projection display application that can realize the fusion of multi-screen images and minimize the splicing gap to completely overlap. In recent years, with the development of software and hardware technology, seamless splicing technology has been widely used in exhibitions, visual entertainment, advertising and other fields. [0003] From the perspective of splicing effects, seamless splicing technology has gone through three stages of development: hard-edged splicing, overlapping splicing and soft-edged fusion splicing. ...
