Embodiment 1

[0041] figure 1 It is a flow chart of a panoramic video distribution method based on visual continuity in a preferred embodiment of the present invention; the method includes the following steps:

[0042] Step0: Choose one of the multi-channel streams of panoramic video, and record it as stream as the reference stream cur , will stream cur The corresponding camera acquisition angle is taken as the reference angle, denoted as θ cur .

[0043] Among them, stream n Represents the nth spliced ​​code stream of the panoramic video, n=1,2,...,N, N represents the number of spliced ​​code streams; θ n Indicates stream n Corresponding camera capture perspective.

[0044] Step1: Calculate the camera acquisition angle and θ corresponding to each code stream of the panoramic video cur The angle difference dθ n , dθ n = θ n -θ cur , n=1,2,...,N.

[0045] Step2: Arrange the panoramic video multiple streams into two stream queues.

Embodiment 2

[0081] Figure 4 It is a structural diagram of a panoramic video distribution system based on visual continuity in a preferred embodiment of the present invention; the system includes:

[0082] The reference code stream and reference angle setting module are used to select one code stream in the multiple code streams of the panoramic video, and record it as stream as the reference code stream cur , will stream cur The corresponding camera acquisition angle is taken as the reference angle, denoted as θ cur .

[0083] Among them, stream n Represents the nth spliced ​​code stream of the panoramic video, n=1,2,...,N, N represents the number of spliced ​​code streams; θ n Indicates stream n Corresponding camera capture perspective.

[0084] The angle difference calculation module is used to calculate the camera acquisition angle and θ corresponding to each code stream of the panoramic video cur The angle difference dθ n , dθ n = θ n -θ cur , n=1,2,...,N.

Abstract

The invention discloses a panoramic video distribution method and system based on visual continuity. According to the method, adaptive distribution of multichannel streams spliced by panoramic videos is realized by employing the human visual continuity, the panoramic videos can distribute the multichannel streams according to the network congestion condition, the watching effect of audiences is not affected, and the playing smoothness of the panoramic videos is improved.

Description

technical field [0001] The present invention relates to the field of video distribution, in particular to a method and system for panoramic video distribution based on visual continuity. Background technique [0002] Panoramic video can provide dynamic real-time video information while providing all-round visual information, so that people can see the entire dynamic scene around the camera. panoramic Figure 1 These images are generally large-resolution images, and their generation requires a lot of computational work. Compared with panoramas, panoramic videos add a new time dimension. Therefore, the amount of calculation and data will be tens of times that of the panorama, which is a great challenge to the processing power of the hardware system and the work efficiency of the software system. When the code stream of the panoramic video is distributed and transmitted, it will put great pressure on the bandwidth of the network, and it will be a great challenge to the mobile...
