Method and device for detecting text information in video and electronic equipment

Abstract

The invention discloses a method and a device for detecting text information in a video and electronic equipment. The method for checking the text information in the video comprises the following steps: extracting a target picture from a to-be-detected video, wherein the target picture comprises a key frame in the to-be-detected video; extracting text information from the target picture, and performing text sentence word segmentation on the text information to obtain sentences after word segmentation; further carrying out vector conversion on the sentences after word segmentation to obtain word vectors of segmented words in the sentences; and finally inputting the sentence subjected to word segmentation and the word vector obtained by conversion into a text classification model; carrying out semantic recognition through the text classification model, and outputting a semantic recognition result representing whether the text information contains characters with preset semantics or not so as to realize the illegal video character detection, namely, by extracting the key frame in the video and semantically identifying the character information, the problem that the illegal video character cannot be detected due to the change of a simple character expression mode is avoided, and the accuracy and the detection efficiency of the illegal video character detection are improved.

Description

technical field [0001] This specification relates to the field of software technology, in particular to a method, device and electronic equipment for detecting text information in a video. Background technique [0002] With the continuous development of network technology, multimedia resources are growing explosively, among which, the growth of video resources is particularly rapid, and the supervision of video quality is particularly important. Video quality includes the supervision of image content and video text. The supervision of image content is mainly to intercept illegal image content, which can be intercepted well through image recognition technology, but for the supervision of video text, due to the variability of text Due to the uncertainty of the position in the video, it is difficult to detect the violation of the video text, and there is an urgent need for a detection method of the text information in the video to realize the detection of the illegal video text...
