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 use of an external seamless splicing processor also faces the disadvantage of high cost and the disadvantage of supporting a small number of channels

Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] As shown in Figures 1 to 5, the present invention combines a plurality of small screens with independent projection equipment into a large screen, and projects the multi-screen images onto irregular screens such as arc screens, ring screens, spherical screens, and hyperboloid screens. And through computer software processing, the deformation correction of the multi-screen images is carried out to realize the automatic splicing of the projection images. 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 the playback end through a local area network. For synchronous control, a camera is connected to the image capture card of the co...

Abstract

This invention relates to one multi-screen play deformation correction method for irregular screen, which comprises the following steps: firstly processing deformation on multi-screen picture to make the projection suitable for irregular screen; then through control end for correction of multiple screens to fulfill multi-screen picture automatic matching; finally melting the picture edge; in playing process, through control end to process simultaneous control.

Description

technical field [0001] The invention relates to multi-screen display and control, in particular to a method for correcting deformation of multi-screen playback suitable for irregular screens. 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 splicing an...
