Problems solved by technology
The current text detection algorithm is to directly detect the text information in the preset video area, and use the text information at this position as the target text. However, in addition to the area where the target text is located, there will be multiple text areas in the video. The text detection algorithm directly detects the text, which may cause the detected area to contain text information in the non-line area, thereby reducing the accuracy of the detection result

The invention relates to a method and device for processing video data, computer equipment and a storage medium. The method comprises the steps of performing text detection on a current frame in a current video to obtain a text region of the current frame; obtaining the line word region of the current video, wherein the line word region of the current video is determined according to a plurality of video sequence frame text areas of the current video; obtaining region information of the overlapping region of the text region and the line word region; respectively calculating the ratio of the height of the overlapping region to the height of the corresponding text region and line word region to obtain a first ratio and a second ratio; and when any one of the first ratio and the second ratiois greater than a preset ratio, taking the text region as a line word region. Compared with the prior art, the line regions of different videos are different, the line region is directly positioned according to the height ratio of the text region of the video frame of the video to the overlapping region of the adaptive line word region according to the line word region adaptively determined by theplurality of video frames in the same video, and the positioning accuracy is improved.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for processing video data. Background technique [0002] In application scenarios such as text search and text translation, it is necessary to first extract the text area of the line area in the video for subsequent OCR recognition and translation. The current text detection algorithm is to directly detect the text information in the preset video area, and use the text information at this position as the target text. However, in addition to the area where the target text is located, there will be multiple text areas in the video. The text detection algorithm directly detects the text, which may cause the detected area to contain text information in the non-line area, thereby reducing the accuracy of the detection result. Contents of the invention [0003] In order to solve the above technical problems, the p...
