Abstract

The invention provides a method, a device and a system for splicing fusion of a panoramic video, and a computer readable storage medium, which relate to the field of video processing. The system includes a panoramic camera device and a panoramic video splicing fusion device. The panoramic video splicing fusion device is used for acquiring image data transmitted by the panoramic camera device, preprocessing the image data to get the optical flow between adjacent image data, carrying out sampling and gradient fusion according to the image data and the optical flow between adjacent image data to get image data after gradient fusion and a mapping grid, stretching and smoothing the image data after gradient fusion according to the mapping grid, and eliminating deformation generated by gradient fusion to get a panoramic video. Through the technical scheme of the invention, panoramic sequence frames are obtained, and a large shooting depth scope is achieved while the calculation efficiency and the picture definition are both considered.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a panoramic video splicing and fusion method, a panoramic video splicing and fusion device, a computer device, a computer-readable storage medium, and a panoramic video splicing and fusion system. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the development of visual image technology and video capture technology, video acquisition has developed from obtaining ordinary viewing angle video to wide-angle video, and further developed to panoramic video of 360 degrees in the horizontal direction and 180 degrees in the vertical direction. In order to obtain a panoramic image, it is necessary to use a panoramic camera composed of two or more lenses to sh...
