Abstract

A three-dimensional watermark adding method, device, and terminal, the method comprising: receiving target watermark information; acquiring dynamic shooting parameter information corresponding to a target video, the dynamic shooting parameter information being used to record when an unmanned aerial vehicle is shooting the target video The dynamic shooting parameters at the time; according to the dynamic shooting parameter information, establish the simulated lens stereo space for the unmanned aerial vehicle to shoot the target video; fuse the target watermark information with the simulated lens stereo space to generate 3D watermarking of the target video. The method can quickly realize adding three-dimensional watermark in the target video.

[0001] The disclosure of this patent document contains material that is protected by copyright. This copyright belongs to the copyright owner. The copyright owner has no objection to the reproduction by anyone of the patent document or the patent disclosure as it exists in the official records and files of the Patent and Trademark Office. technical field [0002] The present invention relates to the technical field of video processing, in particular to a method, device and terminal for adding a three-dimensional watermark. Background technique [0003] The traditional video watermark is a watermark directly superimposed on the video, relying on the editing of the lens to achieve the story expression effect of the video. The traditional video watermark has no correlation with the space of the video screen. At present, in order to achieve a better watermark display effect, such as three-dimensional subtitles in videos, the three-dimensional space and motion in the video can b...
