Title: REAL-TIME GENERATION METHOD FOR 360-DEGREE VR PANORAMIC GRAPHIC IMAGE AND VIDEO
Abstract:
Disclosed is a real-time generation method for a 360-degree VR panoramic graphic image. The method comprises: determining a current camera location and scenario information; rendering a three-dimensional graphic image in a scene photographed by the camera onto a space projection object in real time, and performing combined rendering and capturing and combination to form a fully surrounding panoramic CUBE texture map; in a viewing angle range of 360 degrees, performing spherical projection and second rendering on the texture of the panoramic CUBE texture map, and converting same into a rendered object to generate a panoramic scenario map; and outputting the generated panoramic scenario map via a video IO card to obtain a 360-degree VR panoramic graphic image with a key signal. In addition, also disclosed is a real-time generation method for a 360-degree VR panoramic graphic image video. The method superimposes a panoramic video in a panoramic video signal to a 360-degree VR panoramic graphic image to generate a video with a 360-degree VR panoramic graphic image.
