Problems solved by technology

The fisheye lens can provide a large field of view, but it cannot cover the entire field of view. There is still a large visual blind spot for the image taken by the user. The user cannot see the scene behind the camera.
[0005] Due to the incomplete scene when playing the video produced by the fisheye lens, the existing scheme usually fills the uncaptured area with a fixed black. In new display devices such as virtual reality, this processing method will significantly reduce the user's presence When the user rotates the viewing angle, he will see incoherent black areas, which will have a significant impact on the sense of presence and visual experience

Abstract

The invention discloses a panoramic image-based panoramic video producing method. According to the method, multiple nodes are set, a panoramic image is formed on each node, a camera is set, the cameramoves from one node to another node, the panoramic image on the node rotates by taking the node as the center of a circle, a rotating speed of the panoramic image and a moving speed of the camera areset to be matched with each other, when the camera moves from one node to another node, the panoramic images of the two nodes are spliced, and the camera records to form a video. The method has the advantages of reducing the data amount of the panoramic video greatly while delivering high visual experience, and lowering the costs of content storage and transmission.

Description

technical field [0001] The invention relates to the technical field of video production, in particular to a panoramic video production method based on a panorama. Background technique [0002] Panoramic video is a kind of video content generated by continuously shooting 360-degree full-view images through two or more cameras at the same time and encoding them. The images captured by multiple cameras are spliced ​​together by algorithms to form a video stream containing all perspective information. The panoramic video can record complete on-site image information, and can reproduce the complete on-site scene well on new display devices such as virtual reality helmets. It gives users an immersive feeling and has a very wide range of practical value. [0003] Since panoramic video records information from multiple angles of view at the same time, under the same definition conditions, the frame size of panoramic video will be many times larger than that produced by ordinary cam...
