Abstract

The embodiment of the invention provides a cutting method for displaying a two-dimensional video in a CAVE space, and the method comprises the steps: presetting the size of the CAVE space, and preappointing the position of an optimal viewing point relative to the CAVE space; according to the size of the CAVE space, selecting a two-dimensional video picture suitable for cutting, adjusting the size and position of the video picture, and selecting picture content suitable for being placed on a front screen; according to the height of the optimal viewing point, the horizontal distance between the optimal viewing point and the CAVE space and the sizes of the front screen, the upper screen, the lower screen, the left screen and the right screen, an original video picture is cut into five area pictures; and cutting and manufacturing the five area pictures into a multi-screen picture corresponding to the CAVE space according to the calculated quantitative relationship, and generating a corresponding video file. The invention further provides a corresponding system. According to the invention, the expression form of the two-dimensional video is enriched, the video content seen by audiences at the optimal viewing point has no distortion phenomenon, and the immersion of the audiences when watching the traditional two-dimensional video is enhanced.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a cutting method and system for displaying two-dimensional video in CAVE space. Background technique [0002] Immersive space is an independent, relatively airtight artificial space, manifested as a virtual environment or a space created by humans using tools and technologies. This space can trigger human sensory experience (more visually) through some mechanism. and auditory), thereby stimulating memory. This is a dynamic process for immersive experience, a gradual transition from sensory experience to narrative experience. In the 1970s, the cave-like automatic virtual environment system CAVE (Cave Automatic Virtual Environment) space made the audience realize that they were on the "stage" from the bottom of their hearts through animated images and carefully arranged sounds. The Cave system was originally designed to go beyond the limitations of head-mounted d...
