Embodiment Construction

[0057] In order to make the principles and technical solutions of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0058] Text detection technology can be applied to a variety of scenarios. When the text detection technology is implemented in the video, by locating and identifying the text area in the digital picture, it can assist the user to track and analyze the text. For example, figure 1 A schematic diagram of the application of a video text detection method provided in the embodiment of the present application in an automatic driving scene. A video text detection device can be installed on the vehicle. The video text detection device recognizes the text that appears on the vehicle's driving path. assisted automatic driving. For another example, the video text detection method can be applied to text content review scenarios, such as news conte...

Abstract

The invention discloses a video character detection method and device, and belongs to the field of AI. The method comprises the steps of obtaining a video, where the video comprises n frames of pictures, and n is an integer larger than 1; recognizing characters in each frame of picture of the video to obtain a character recognition result of the video, the process of recognizing the characters in the kth frame of picture in the video comprising: acquiring the characters in the kth frame of picture, k being greater than 1 and less than or equal to n; and based on the feature vector of the characters in the kth frame of picture and the feature vector of the characters appearing in the picture before the kth frame of picture in the video, matching the characters in the kth frame of picture with the characters appearing in the picture before the kth frame of picture. The character recognition efficiency can be improved.

Description

technical field [0001] The present application relates to the field of artificial intelligence (AI), in particular to a video text detection method and device. Background technique [0002] Text detection technology (also called text detection and recognition technology) usually requires locating and recognizing text areas in digital pictures in various scenarios. [0003] At present, the text detection technology for video can only recognize each frame of picture in the video separately, and the obtained video text recognition result is only a summary of the text recognition results of each frame of picture, resulting in poor user experience. Contents of the invention [0004] Embodiments of the present invention provide a video text detection method and device. Described technical scheme is as follows: [0005] In a first aspect, a text detection method of a video is provided, the method comprising: acquiring a video, the video including n frames of pictures, n being a...
