Embodiment Construction

[0032] The specific implementations of the multi-screen splicing method and device and the multi-projection splicing large screen of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] see figure 1 , figure 1 It is a flow chart of the multi-screen splicing method, including the following steps:

[0034] S101. Observing the model of the multi-screen according to the simulated camera at the set viewing position to obtain the size ratio of each screen of the multi-screen image.

[0035] The above steps are to observe the multi-screen three-dimensional model through an analog camera at a viewing position set in the multi-screen three-dimensional model pre-built in the software.

[0036] Wherein, the multi-screen can be a large screen formed by a plurality of flat screens connected adjacently at any angle, so the spliced ​​large screen can be non-planar, for example, it can be formed by connecting two adjacent screens at a...

Abstract

The invention relates to a multi-screen splicing method, a multi-screen splicing device and a multi-projection splicing large screen. The method comprises the following steps of observing a multi-screen model according to an analog camera arranged on an observation position, observing to acquire a proportion of the size of each screen of a multi-screen image, segmenting a received main frame imageaccording to the observed proportion of the size of each screen to acquire a sub-picture corresponding to each screen, stretching the sub-picture according to an actual resolution ratio of each screen on an observation site to acquire a sub-image actually displayed on each screen, and separately displaying the sub-image on each screen. According to the multi-screen splicing method, the scheme operation process is simple and efficient, and the quick splicing and displaying effect of the multiple screens can be achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a multi-screen splicing method and device, and a multi-projection splicing large screen. Background technique [0002] With the development of display technology, for example, in some large conference rooms, exhibition halls, projection halls, etc., in order to create a better visual immersive experience, non-flat screens are often used to display a whole picture. Flat screens mainly include curved screens, spherical screens, and large screens composed of multiple flat screens connected at a certain angle. [0003] In order to realize the effect of displaying an overall video image on a large screen spliced ​​by multiple flat screens, the method of multi-screen splicing has been widely used. For example, multi-screen projection mosaic display, it divides an overall video image into multiple sub-images, and uses multiple projectors to project multiple sub-images onto multiple sc...
