Method for interactively playing panoramic video stream on CAVE projection system

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.
