Abstract: The present disclosure provides a video generation method, an apparatus, a system, a device and a storage medium. The method is applied to a video generation system, and the video generation system includes a first client and at least one second client. Specifically, the method includes: firstly, the first client creates a first virtual room and sets a target capturing effect for the first virtual room; then, the second client acquires a first video added with the target capturing effect after receiving a notification message that a current user has successfully joined the first virtual room, and uploads the first video to the first virtual room. Further, the first client acquires a target video from the first virtual room and generates a target result video based on the target video, and the target video includes the first video.

Abstract: Disclosed in the present application are a concrete protection material, and a preparation method and a construction method therefor. The concrete protection material consists of 50%-90% of a component A and 10%-50% of a component B in percentage by weight, where the component A is prepared from 30%-65% of organic silicon, 2%-5% of nano-silicon dioxide and the balance of an organic solvent in percentage by weight; and the component B is prepared from 20%-50% of an organic base and the balance of water in percentage by weight. The present application not only can form nano-particles having a strengthening effect in capillary channels of a concrete surface layer, but also can achieve a technical effect of superhydrophobicity on the concrete surface layer.

Abstract: A progressive localization method for text-to-video clip localization. The method comprises: first, respectively extracting features of two modes, namely a video mode and a text mode by using different feature extraction methods; then progressively selecting different step sizes, and learning the correlation between the video and the text in multiple stages; and finally, training a model in an end-to-end manner based on the correlation loss of each stage. Moreover, the fine time granularity stage is fused with information of the coarse time granularity stage by means of a condition feature update module and up-sampling connection, such that different stages are mutually promoted. Different stages can pay attention to clips with different time granularities, and the model can cope with the situation that the length of a target clip is obviously changed based on the interrelation between the stages.

Abstract: The present application relates to the field of security and protection, and provides a pan-tilt control method, device and system. The method comprises: detecting whether there is a signal source within a monitored region of a pan-tilt camera, the pan-tilt camera comprising a pan-tilt and a camera attached to the pan-tilt; judging, when there is a signal source within the monitored region, whether signals emitted from the signal source are position adjusting signals for indicating a position adjustment on the pan-tilt; and adjusting a position of the pan-tilt according to a position of the signal source when the signals emitted from the signal source are position adjusting signals. In the present application, the trigger delay of the control operation on the pan-tilt camera is reduced.
