Abstract

The invention discloses a method for interactively playing a panoramic video stream on a CAVE projection system, which belongs to the technical field of digital media. A conventional 360-degree panoramic video browser does not support the interactive play of the panoramic video stream on the CAVE projection system. The method comprises the following steps of: mapping panoramic picture images onto a 3D sphere as textures, splitting a 360-degree all-round spherical view field into six sub-areas, and shooting a front sub-area, a rear sub-area, a left sub-area, a right sub-area and a zenith sub-area respectively by using five different virtual cameras to obtain the pictures on each projection screen of the CAVE projection system respectively. The method has the advantage of the capacity of solving the problem that the panoramic video stream cannot be interactively played on the CAVE projection system, simplicity, practicability, no need of expensive special equipment, real-time interaction capacity, relatively lower implementation cost and convenient popularization and application.

Description

technical field

[0001] The invention belongs to the technical field of digital media, and relates to a method for interactively playing panoramic video streams recorded by a panoramic camera on a CAVE projection system. Background technique

[0002] The CAVE projection system is a cave-type orthogonal multi-screen projection system. Images are projected onto the screen in the form of rear projection. The projection adopts the form of "virtual reality theater" and fully complies with the Showcase standard. The CAVE projection system is a cubic space. Typically, there is a projection screen on each of the front, back, left, and right walls, and there is also a projection screen on the zenith. Therefore, the CAVE projection system is an ideal device for displaying panoramic video images. Present panorama camera (for example the Ladybug panorama camera of PointGrey company) majority can save the panorama video of recording with the form of stream file, use existing 360 degree p...
