Problems solved by technology

However, this method must use expensive professional video capture equipment, and the panorama is obtained by transforming one image, so the resolution is obviously not as good as the traditional stitched panoramic image
And the closer to the center point of the surface reflection image, the greater the deformation of the image and the worse the correction effect

Embodiment

[0090] As shown in Figures 4, 5, and 6, the application of this method and system in the scenario-based virtual tourism system requires the collection of panoramic videos on the main routes in the virtual tourism, which has higher requirements for the resolution of the video and must be able to To adapt to outdoor collection, it is difficult for the previous panoramic video methods to meet these conditions. The specific steps of the implementation of this example are described in detail below:

[0091] (1) Six cameras are used to collect video in all directions covering different viewing angles. Figure 9 shows the physical picture of the self-made panoramic video capture device. The relative position of each camera is fixed, and it shoots in different directions around the same center on the horizontal plane. The horizontal viewing angle range of the camera is about 80 degrees, and the angle between adjacent cameras is about 60 degrees. The cameras are connected in series. Co...

Abstract

The invention discloses a method for forming a panoramic video based on multi-view video streaming, which comprises the following steps: 1) using a plurality of cameras to capture video with an omnidirectional coverage at different viewing angles; 2) establishing one-to-one correspondence of synchronous frames in each video streaming; 3) correcting each video streaming independently by the camera's calibration; 4) panoramically joining a group of the synchronous video frames and calculating the joint parameter of each frame; 5) applying the jointed parameter to the joint of each frame in each video streaming to obtain a panoramic video formed by the panoramic frames. Compared with the prior method that uses a concave lens or a convex lens to focus lights and then reduce into a panoramic video, the invention has the advantages of low cost, no picture distortion, and suitability for the shooting during movement.

Description

technical field [0001] The invention relates to computer video splicing, in particular to a method for generating panoramic video according to multi-view video streams. Background technique [0002] Video plays a very important role in the expression of information. With the development of information technology, the research and application of video images have also developed rapidly, such as video conferencing, videophone, video surveillance and virtual reality. However, at present, due to the limited field of view of a single camera, users cannot watch scenes of their own interest from different angles at the same time, which cannot meet individual requirements. Panoramic Image based on image rendering [1][2] (Panoramic Image) is to completely display the discrete image information on one image. The emergence of panoramas overcomes the limitation of viewers passively observing fixed viewing angles, but panoramic images express a static scene and carry a limited amount of...
