Abstract

The invention provides a real-time splicing processing method for a multichannel ultrahigh resolution panoramic video. The method comprises the following steps of transforming two-dimensional coordinates of an output image of the panoramic video in a two-dimensional coordinate system into longitude and latitude coordinates in a longitude and latitude coordinate system; transforming the longitude and latitude coordinates into normalized Cartesian orthogonal coordinates; determining a target input plane according to the normalized Cartesian orthogonal coordinates; computing in-plane two-dimensional coordinates in each target input plane; and splicing the in-plane two-dimensional coordinates to form the panoramic video in real time. Through adoption of the technical scheme of the invention, the splicing of the multichannel ultrahigh resolution panoramic video can be completed under the lower hardware cost in a real-time, efficient and lossless manner.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a high-definition video data processing method, specifically a multi-channel ultra-high resolution panoramic video real-time splicing processing method. Background technique [0002] In recent years, with the rapid development of image processing technology and digital video technology, virtual reality (VR, Virtual Reality) technology has been widely used in fields such as games, education, military affairs and medical treatment. Nowadays, people's requirements for visual experience are becoming more and more stringent. Users hope to watch panoramic videos with higher resolution through VR devices, but they are often limited by hardware devices, and users' requirements cannot be met. Panoramic video is usually composed of multiple cameras. For example, there is a fisheye panoramic camera on the market, but the video obtained by this lens is prone to distortion, a...
