Problems solved by technology

[0004] Currently, subtitles such as video name, cast and crew names, captions, and character introductions in video works are mainly configured manually. low, high labor costs
In terms of live broadcasting, the manual configuration of subtitles will have higher requirements, and the subtitle configuration staff needs to be highly concentrated in order to complete the configuration of live video subtitles. However, the subtitle configuration staff is also prone to negligence during work. Or due to unexpected circumstances at the work site, the subtitle configuration effect of the live broadcast video is not ideal, which affects the audience's video perception

Abstract

The invention provides an automatic subtitle configuration method and device. The automatic subtitle configuration method comprises the following steps of receiving video data of a live site, whereinthe video data of the live site at least comprises a live broadcast picture; carrying out image recognition on the live broadcast picture, and judging whether matching degree of the live broadcast picture and a pre-stored picture reaches a preset threshold or not; and if the matching degree of the live broadcast picture and the pre-stored picture reaches the preset threshold, configuring pre-stored subtitles on the live broadcast picture. The automatic subtitle configuration method and device are applicable to configuration of live video subtitles, the live broadcast pictures in the received live video can be recognized, and the corresponding subtitles are automatically configured when a recognition condition is judged to meet expectation, so that a subtitle configuration effect of the live video is more ideal, the video impression of an audience is guaranteed, and meanwhile, the labor cost is effectively saved.
