Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] Panoramic video is a video formed by mapping video images on the surface of an image sphere. Panoramic video can include N subtitle spheres, where N is an integer greater than or equal to 1, the center of each subtitle sphere in the N subtitle spheres, the image The center of the sphere coincides with the coordinate origin of the spherical coordinate system. In an optional embodiment of the present invention, the radii of each of the N subtitle spheres are not equal.

[0056] The execution subject in any of the following embodiments provided by the present invention may be a terminal or a server, and the terminal may be a mobile phone, a desktop computer, a notebook computer, a camera or a camera, and the like.

Abstract

Disclosed are a method and apparatus for generating subtitles, wherein same fall within the field of videos. The method comprises: acquiring a first position, in a plane coordinate system, of a pixel point comprised in a character to be generated; calculating, according to the first position of the pixel point, a second position of the pixel point on a subtitle spherical surface; and rendering, according to the second position of the pixel point, the pixel point on the subtitle spherical surface, so as to form the character to be generated. The apparatus comprises: an acquisition module, a calculation module and a rendering module. According to the embodiments of the present application, subtitles of a panoramic video can be displayed.

Description

technical field [0001] The invention relates to the video field, in particular to a method and device for generating subtitles. Background technique [0002] Panoramic video is a video that stitches one or more groups of photos taken by a 360-degree camera ring into a panoramic image, and maps multiple panoramic images on the surface of a ball in turn to form a frame of video. It can be used in the spatial domain Provide users with a new experience of 360 degrees without dead ends, and provide a virtual 3D environment. [0003] The user can use the player to play the panoramic video, and when playing the panoramic video, the user can change the viewing angle of the video by selecting a viewpoint to improve the user's interactive experience. But the fly in the ointment of current panoramic video is that there are no subtitles. Contents of the invention [0004] In order to be able to display the subtitles of the panoramic video, the present invention provides a method and...
