according to the watermark adding scheme corresponding to the matching of the target object and the picture scene, the watermark adding scheme comprises watermark content adaptive to the target object and a watermark content display strategy matched with the picture scene;
and adding the watermark content adapted to the target object to the video frame corresponding to the target object according to the watermark content display strategy.
2. A video watermarking method according to claim 1, wherein the watermark content includes a profile of the target object and a video source;
the watermark content display strategy comprises the following steps: the watermark content display mode comprises a watermark content display mode and a watermark content display duration, wherein the watermark content display mode comprises a dynamic display mode and a static display mode.
3. The video watermarking method of claim 1, wherein the matching of the corresponding watermarking schemes according to the target object and the picture scene comprises:
analyzing feature labels of both the target object and the picture scene;
and acquiring a corresponding watermark adding scheme according to the preset mapping relation between the feature labels of the two and the watermark adding scheme and the feature labels of the two.
4. A video watermarking method according to claim 1, wherein the analyzing the picture scene of the video frame comprises:
extracting each image feature of the video frame;
and inputting each image characteristic into a pre-trained neural network model for picture scene recognition to obtain a picture scene of the video frame.
5. A video watermarking system, comprising:
the system comprises a watermark requirement processing module, a watermark detection module and a watermark analysis module, wherein the watermark requirement processing module is used for identifying a target object needing to be added with a watermark and a video frame corresponding to the target object from a video to be processed and analyzing a picture scene of the video frame;
