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, and 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

Embodiment Construction

[0011] The panoramic video production technology of mixed images described in this specific embodiment, the technology is: in a 360-degree panoramic shooting scene, the shooting system adopts a multi-lens imaging system, and covers a 360-degree panoramic viewing angle by a plurality of lens modules, Some lens modules capture lens images, and some lens modules capture video. When shooting, the shooting area needs to be planned as a static area and a dynamic area. The dynamic area is represented by video shooting and encoding, and the static area is recorded by shooting still pictures, and the captured still images and videos are mixed and encoded into the same code stream. , a scene can be fully recorded.

[0012] In many practical application scenarios of panoramic video shooting, the importance of the content of different perspectives to the program is often very different. Background, these backgrounds can be designed to be stationary in many scenes; still scenes can be rep...

Abstract

The invention relates to the technical field of panoramic videos, in particular to a panoramic video production technology for a hybrid image. The technology comprises the following steps that a region which needs to be shot is planned to a stationary region and a dynamic region in a 360-degree panoramic shooting scene, a panoramic imaging system provided with a plurality of lenses to shoot a panoramic content, the dynamic region is represented through video shooting and encoding, the stationary region is recorded in a way of shooting a stationary picture, and hybrid encoding is carried out on the shot stationary picture and the video in the same route of code stream, so that one scene can be completely recorded. According to the panoramic video production technology for the hybrid image, the data volume of the panoramic video can be greatly reduced on the premise of keeping the high visual experience, and the cost for content storage and transmission is reduced.

Description

technical field [0001] The invention relates to the technical field of panoramic video, in particular to a panoramic video production technology of mixed images. 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 came...
