Problems solved by technology

However, when the user sends a query request, it may happen that the video frame containing the front face of the person in the video image has already been played, and the current video frame only shows the side face or back of the person, or the face is not clear in the current video frame , the identity of the person cannot be accurately identified using face recognition technology
This usually results in a failure to identify
The user can only improve the recognition rate and satisfaction by pausing the video frame with the front face of the person or the time point of capturing the front face of the person, and the user experience is not good.

Abstract

The invention discloses a character recognition method and device, electronic equipment and a storage medium, and relates to the technical field of image recognition. According to the specific implementation scheme, the method comprises the steps of receiving a character recognition request corresponding to a current video frame in a video stream; extracting human body features in the current video frame; matching the human body features in the current video frame with the human body features of a first video frame in a video stream stored in a knowledge base; and under the condition of successful matching, taking the first character identifier of the first video frame as an identification result of the character identification request. In the embodiment of the invention, when the character recognition request is sent out, a user does not need to capture the video frame with the front face of the character, and the character information in the video can be inquired according to the human body characteristics in the current video frame, so that a convenient inquiry service can be provided, the user viscosity is improved, and the user experience is good.

Description

technical field [0001] The present application relates to the field of information technology, in particular to the field of image recognition technology. Background technique [0002] During the process of watching a video, a user may want to query information about characters in the video. However, when the user sends a query request, it may happen that the video frame containing the front face of the person in the video image has already been played, and the current video frame only shows the side face or back of the person, or the face is not clear in the current video frame , the identity of the person cannot be accurately identified using face recognition technology. This situation usually results in a recognition failure. The user can only improve the recognition rate and satisfaction by pausing the video frame with the front face of the person or the time point of capturing the front face of the person, and the user experience is not good.
