Abstract
The invention provides a table extraction method and device and a touch display device, and relates to the technical field of image recognition. The method comprises the following steps: receiving an operation instruction for performing screen capture on content displayed on a screen of the touch display device, performing screen capture on the content displayed on the screen according to the operation instruction to obtain a screen capture picture, detecting the screen capture picture to obtain a second table corresponding to a first table, identifying characters in the screen capture picture, establishing a matching relationship between the second table and the characters, and storing the second table, the characters and the matching relationship. When a user needs to store the content displayed on the screen, the operation instruction for performing screen capture on the content displayed on the screen can be triggered to perform screen capture, then the second table corresponding to the first table in the screen capture picture and the characters in the second table are automatically extracted, and the second table and the characters are stored as the target document; and the user can subsequently edit the content displayed on the screen again based on the target document, so the operation experience of the user is improved.
Description
technical field [0001] The present invention relates to the technical field of image recognition, in particular to a table extraction method, device and touch display device. Background technique [0002] Touch display devices usually use a touchable display screen as a carrier, and use multi-point infrared, optical and other touch methods to perform human-computer interaction, and realize operations such as writing on the touch display screen. Touch display screens are usually used in Meetings, teaching and other scenes. [0003] At present, users can draw tables, Chinese, English, numbers and other content on the touch display screen. After the drawing is completed, if the user needs to save the drawn content, he can save the drawn content on the screen as a picture by taking a screenshot. [0004] However, the content drawn on the screen is saved in the form of a picture, and after the user opens it again, the drawn content cannot be edited again. Contents of the inven...
