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
[0006] Since the brightness of a video usually changes with the content of the video, if a fixed fusion curve is used to fuse the entire video, the fusion area will be darker when playing a dark picture, and brighter when playing a bright picture.

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] As shown in Figures 2 and 3, the present invention combines a plurality of small screens with independent projection equipment into a large screen, which is projected onto irregular screens such as arc screens, ring screens, spherical screens, and hyperbolic screens to realize the overall picture. Synchronous playback, and through computer software processing, the dynamic parameters required for edge fusion are obtained by automatic fusion preprocessing, and the synchronous control of multi-screen images on the playback terminal is performed regularly through the control terminal. The present invention is made up of a plurality of ordinary PCs, a plurality of ordinary projectors and a video camera, each of the graphics accelerator cards of the PCs used as the playback end is connected to a projector, and another PC is used as the control end to perform the playback on...

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 an automatic fusion preprocessing method for multi-screen playback suitable for irregular scenes. Background technique [0002] In the display and control technology mainly based on splicing, the seamless splicing technology used to realize the seamless fusion display of images is one of the important technologies. Seamless splicing technology is a special projection display application with relatively high requirements, which can realize the fusion of multiple 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 effect, seamless splicing technology has gone through three stages of development: hard edge splicing, overlapping splici...
