Embodiment 1

[0020] The adjustment method of the panoramic video in the embodiment of the present invention is introduced in detail.

[0021] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a method for adjusting a panoramic video according to the present invention, which may specifically include the following steps:

[0022] Step S102, binding the panoramic image frame of the panoramic video with the spherical model to generate an output video frame.

[0023] Panorama source data includes 720-degree or 360-degree panoramic video sources, and dynamic videos can be watched at any angle of 360 degrees up, down, left, and right at the camera position. The panorama source data includes multiple panoramic image frames. The panorama source data needs to use a stereoscopic model such as a spherical model to achieve the 3D stereoscopic effect of panorama playback. This can be achieved by binding the stereo model with the panoramic image frames of the panorama source ...

Embodiment 2

[0031] The adjustment method of the panoramic video in the embodiment of the present invention is introduced in detail.

[0032] refer to figure 2 , which shows a flow chart of the steps of another embodiment of a method for adjusting a panoramic video according to the present invention, which may specifically include the following steps:

[0033] Step S202, establishing a spherical model based on model information, wherein the model information includes vertices, normal vectors and spherical texture coordinates of the spherical model.

[0034] Step S204, analyze each panoramic video frame, and determine the image texture information of each panoramic video frame.

[0035] To bind the panoramic video frame with the spherical model, it is necessary to first obtain the data information of the panoramic video frame and determine the model information of the spherical model, and map the panoramic video frame to the spherical model according to the data information and model info...

Embodiment 3

[0062] refer to image 3 , shows a structural block diagram of an embodiment of an apparatus for adjusting a panoramic video according to the present invention, which may specifically include the following modules: a binding module 302, a converting module 304, and an adjusting module 306, wherein:

[0063] The binding module 302 is configured to display the adjusted panoramic video by playing the adjusted output video frame when video-on-demand or live video is performed in the mobile terminal.

[0064] A conversion module 304, configured to receive an adjustment instruction, and convert the adjustment instruction into model adjustment information corresponding to the spherical model;

[0065] The adjustment module 306 is configured to adjust the output video frame according to the model adjustment information, and generate an adjusted output video frame.

[0066] In summary, the panoramic image frame of the panoramic video is bound to the spherical model to generate an outp...

Abstract

The embodiment of the invention provides a panoramic video regulation method and device. The video playing method and device allow the video to play more flexible and be more abundant in function. The method comprises: binding the panoramic image frame of the panoramic video with a spherical model, and generating an output video frame; receiving a regulation instruction, converting the regulation instruction to the model regulation information corresponding to the spherical model; and regulating the output video frame according to the model regulation information, and generating a regulated output video frame. The video playing method and device perform corresponding regulation and displaying of the panoramic film source through the user's regulation operation so as to allow the panoramic video to play more flexible and enrich the play functions of the panoramic video.

Description

technical field [0001] The present application relates to the field of mobile Internet technology, and in particular to a method and device for adjusting a panoramic video. Background technique [0002] At present, users use terminal equipment to enter the live video or video-on-demand system to watch videos. They can watch live programs or choose favorite programs to play after searching according to their personal preferences. For example, on smart phones, computers, and smart TVs, you can enter the video live broadcast or video-on-demand system to watch video data. [0003] In the live broadcast or on-demand system of mobile video, the video content that users can watch depends on the video source. Panoramic video is a smooth and clear dynamic video image composed of countless panoramic pictures connected in series. The current maturity of panoramic video stitching algorithms and the popularity of panoramic recording equipment have made more and more sources of panorami...
