Description
技术领域 technical field
本发明属于视频融合技术领域，尤其涉及一种分布式视频融合系统中多台视频融合设备的控制装置。 The invention belongs to the technical field of video fusion, and in particular relates to a control device for multiple video fusion devices in a distributed video fusion system.
背景技术 Background technique
随着网络技术、计算机处理技术的发展，更高分辨率、更大画面的视频备受欢迎，这是因为更高的分辨率能够提供更多的视频内容细节，更大的画面能够带给用户身临其境的观赏效果，仿佛身处在整个画面中一样。 With the development of network technology and computer processing technology, videos with higher resolution and larger screens are popular, because higher resolution can provide more details of video content, and larger screens can bring users The immersive viewing effect is as if you are in the whole picture.
为了达到更大的画面尺寸、更清晰的画面质量和更加明亮的投影画面，人们对于投影仪或显示屏幕的性能要求越来越来高，但现在市面上存在的多种设备都很难达到人们需要的性能指标，所以投影融合技术应运而生，它是一种多媒体技术，是一种针对如今投影技术的发展应运而生的新技术，在商业宣传、大型展馆、视频会议、大型3D游戏开发、军事模拟训练方面都有着广泛的应用。 In order to achieve larger picture size, clearer picture quality and brighter projection picture, people have higher and higher performance requirements for projectors or display screens, but it is difficult for many devices on the market to meet people’s The required performance indicators, so projection fusion technology came into being, it is a multimedia technology, is a new technology for the development of today's projection technology emerged as the times require, in commercial promotion, large exhibition halls, video conferencing, large 3D games Development, military simulation training has a wide range of applications.
通常视频融合系统中会采用两种结构，第一种是使用单台性能很高的视频融合设备，同时输出多个画面，该结构的好处是控制方便，但同时也为今后整套系统的拓展性造带来了困难；第二种是采用多台性能一般的视频融合设备协同完成视频融合任务，这样多台视频融合设备之间能够相互独立的工作，整个系统具有很好的可拓展性，但是多台视频融合设备之间如何协同工作是比较难解决的问题。 Usually, two structures are adopted in the video fusion system. The first one is to use a single high-performance video fusion device to output multiple images at the same time. The second is to use multiple video fusion devices with general performance to cooperate to complete the video fusion task, so that multiple video fusion devices can work independently of each other, and the entire system has good scalability, but How to cooperate with multiple video fusion devices is a difficult problem to solve.
就第二种结构而言，视频融合系统本身就存在着很多需要多台设备同时完成的任务，诸如：重叠区域的几何校正、边缘融合、同步播放等。在以上列举的任务中，缺少了任何一台设备的参与，都不能达到预期播放效果。另外，由于多台视频融合设备的存在，对于场地也有着比较高的需求，即需要有足够大的场地来容纳整个视频融合系统。 As far as the second structure is concerned, the video fusion system itself has many tasks that need to be completed by multiple devices at the same time, such as: geometric correction of overlapping areas, edge fusion, and synchronous playback. In the tasks listed above, without the participation of any device, the expected playback effect cannot be achieved. In addition, due to the existence of multiple video fusion devices, there is also a relatively high demand for venues, that is, a venue large enough to accommodate the entire video fusion system is required.
综上，现有技术中的视频融合系统存在着一系列的问题，视频融合需 要播放的视频分辨率不断提升，其带来的融合处理数据量也在不断上升，由于单台融合设备的计算能力有限，显示设备的能力也受限，所以需要采用多台视频融合设备和多台显示设备来共同完成视频融合任务。但各个视频融合设备之间又存在难以协调工作的问题，本发明就如何控制多个视频融合设备进行协同工作提出了解决方案。 To sum up, there are a series of problems in the video fusion system in the prior art. Video fusion needs to increase the resolution of the video to be played, and the amount of fusion processing data it brings is also rising. Due to the computing power of a single fusion device The capability is limited, and the capability of the display device is also limited, so it is necessary to use multiple video fusion devices and multiple display devices to jointly complete the video fusion task. However, there is a problem that it is difficult to coordinate work among various video fusion devices, and the present invention proposes a solution on how to control multiple video fusion devices to perform cooperative work.
