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 panorama video production method based on a panorama. Multiple nodes are set, a panorama picture is formed at each node, a camera is set, the camera moves from one node to another node, and the panorama picture on the node is The node rotates at the center of the circle, and the rotation speed of the panoramic picture is set to match the moving speed of the camera, so that when the camera moves from one node to another node, the panoramic pictures of the two nodes are spliced ​​correspondingly, and the camera records to form a video. The advantage is that it can greatly reduce the data volume of the panoramic video and reduce the cost of content storage and transmission under the premise of maintaining a high visual experience.

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...
