Panorama video stitching system based on VR Works 360 video

As the vision captured by a single camera is limited, panoramic video technology has emerged. Panorama video is to synthesize a real-time video that can watch surrounding 360-degree scenes by taking multiple videos of surrounding scenes. This article builds on the VRWorks 360 video software development kit released by NVIDIA to build a real-time stitching system. Collect 4 channels of video stream with a resolution of 1920×1080 to produce a panoramic real-time video with a resolution of 4k. In the experiment, four module cameras are used to collect the video stream in real time. In the process of stitching, we fully combine the respective advantages of the CPU and the GPU, and use GPU to accelerate the real-time video stitching. Experimental results show that the stitching system can output high-quality panoramic video.
