Image playing system and method based on spherical display screen

Abstract

The invention discloses a playing system and method based on a spherical display screen, and belongs to the field of spherical display screen playing application, and the system comprises an input terminal which is used for obtaining a three-dimensional spherical image and carrying out the image processing so as to obtain a planar rectangular 2: 1 image, and outputting the planar rectangular 2: 1image; a display controller in communication connection with the input terminal and is used for receiving and outputting the planar rectangle 2: 1 image; and a spherical display screen in communication connection with the display controller and used for receiving the planar rectangle 2: 1 image and displaying the planar rectangle 2: 1 image on the three-dimensional spherical surface of the spherical display screen. The invention has the beneficial effects that; a series of work such as image segmentation, geometric correction and image fusion does not need to be performed by a media server; compared with the prior art, the invention has the advantages that the image pixels on the wefts of the sphere are directly displayed on the spherical display after being subjected to point extraction according to a certain mode, so that the image processing flow is simplified, the processing speed of the spherical display is increased, and the problems of image delay jamming and inter-region desynchrony in image processing of a traditional media server are solved.

Description

technical field [0001] The invention relates to the application field of spherical display screen playback, in particular to an image playback system and method based on a spherical display screen. Background technique [0002] Existing virtual reality (Virtual Reality, VR) needs to wear VR glasses when watching, and the immersive feeling is affected, and there is a sense of vertigo when watching for a long time. [0003] The existing mainstream LED display display method is based on the rectangular image displayed on the plane, and when the rectangular image is directly converted into a hyperboloid image, image deformation and distortion will occur. In particular, the spherical LED display screen composed of a hyperboloid screen has serious image distortion and distortion at the north and south poles. [0004] The existing method of spherical LED display to solve image deformation and distortion is to geometrically correct the image through the media server. Although the p...

[0003] The existing mainstream LED display display method is based on the rectangular image played on the plane, and when the rectangular image is directly converted into a hyperboloid image, image deformation and distortion will occur

In particular, the spherical LED display composed of hyperbolic screens has serious image distortion and distortion at the north and south poles.

[0004] The existing method of spherical LED display to solve image deformation and distortion is to geometrically correct the image through the media server. Although the problem of image deformation and distortion has been solved, due to the increase of the playback process, the image will be processed by the traditional media server. Problems with image lag, stuttering, and out-of-sync between regions
