Embodiment approach
[0192] As an implementation manner of the embodiment of the present invention, the above-mentioned device may also include:
[0193] Reboot state determination module ( Figure 7 not shown in ), used to determine whether the video currently played by the terminal is in a re-rotation state before receiving the target image sent by the terminal;
[0194] Wherein, the replay state indicates that the pre-established object information database corresponding to the video is in a re-established state, and the object information database includes the correspondence between time points and object information.
[0195] The first execution module ( Figure 7 not shown in ), for if yes, performing the step of receiving the target image sent by the terminal;
[0196] Time point determination module ( Figure 7 Not shown in ), if not, determine the video playback time point when the terminal acquires the object recognition instruction, as the time point to be queried;
[0197] Object i...

The embodiment of the invention provides a method and device for identifying object information in a video and a server, and the method comprises the steps: receiving a target image sent by a terminal, the target image being a current video image of a played target video obtained by the terminal when an object identification instruction is obtained, and the target image comprising a target object;extracting image features of the target image, and determining similarity features of the target image as target features according to the image features; based on the similarity between the target feature and each similarity feature included in a feature database, searching the target similarity feature matched with the target feature from the feature database, and the feature database being a pre-established database including the corresponding relationship between the similarity feature and the object information; and sending the object information of the target object corresponding to thetarget similarity feature to the terminal. By adopting the embodiment of the invention, the identification accuracy of the object information can be improved.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and server for identifying object information in video. Background technique [0002] In the process of watching the video, the user may have the need to understand the object information in the video. The object in the video can be a commodity, a person, a building, etc., and the object information is related to the object, indicating the nature and characteristics of the object. Some information, for example, if the object is a commodity, the object information may be the name, price, and position of the commodity in the video frame. [0003] At present, the way to determine the object information in the video is: the server can perform image recognition on the video frame of the video in advance, determine the object information of the target object in the video frame, and then determine the corresponding time point in the video frame of the t...
