Abstract

The invention relates to a video character detection method and device. The method comprises the following steps: carrying out shot segmentation on a target video to obtain each sub-lens segment of the target video; performing character detection on the key frames in each sub-lens segment to obtain a character detection result corresponding to each key frame; for any sub-lens segment, combining the character detection results corresponding to the key frames in the sub-lens segment to obtain a combination result corresponding to the sub-lens segment; and according to the combination result, determining a character detection result corresponding to the sub-lens segment. Character detection is performed based on the key frame of each sub-lens segment, so that the detection amount of characterdetection of a video can be greatly reduced, the character detection efficiency is improved, and a user can know a specific source segment of a character detection result.

Description

technical field [0001] The present disclosure relates to the field of video technology, and in particular, to a video text detection method and device. Background technique [0002] In related technologies, when text detection is performed on a video, text detection is performed on each video frame of the video, and a text detection result of the entire video is returned. The text detection method of this video has a large amount of detection and low efficiency, and the user cannot know which segment of the video the text detection result comes from. Contents of the invention [0003] In view of this, the present disclosure proposes a video text detection method and device. [0004] According to an aspect of the present disclosure, a video text detection method is provided, including: [0005] Segmenting the target video to obtain each segment of the target video; [0006] Perform text detection on the key frames in each segment, and obtain the text detection results co...
