Point reading position marking method and system based on image recognition and intelligent learning desk

Abstract

The invention discloses a point-reading position marking method based on image recognition. The point-reading position marking method comprises the following steps: projecting a marking image to a reading page through a projection device; and acquiring an image of a reading page and a marking image through an image acquisition device. The invention further provides a point-reading position marking system based on image recognition and an intelligent learning desk, and the point-reading position marking system and the intelligent learning desk are used for achieving the point-reading position marking method based on image recognition. By adopting the technical scheme, not only can information such as characters, letters and patterns on the reading page be obtained, but also the position of the marked image is collected, so that other operations such as pronunciation or explanation, search and the like after the position guided by the marked image is recognized by an image recognition technology subsequently are facilitated; and due to the fact that projection of the marking image is conducted through the projection device, no trace is formed on the reading page, and point-reading can be conducted on any reading page.

Description

technical field [0001] The invention relates to an image recognition-based point-reading position marking method, a system and an intelligent learning table, belonging to the technical field of methods and systems for assisting learning. Background technique [0002] At present, although some picture books are read, students can point and read the corresponding point reading area through the point reading pen, but for ordinary paper books, students encounter words they don’t know, idioms they don’t understand, and words they can’t read. Words, math problems that cannot be calculated, etc., cannot be quickly consulted, and usually only teachers or parents can be asked for help. In the prior art, there is also an image recognition method for ordinary books, and then a positioning technology is used to locate the text to be recognized, so as to perform Optical Character Recognition (OCR) on the positioned text. When locating, fingers or other pointers are usually used to point...

Problems solved by technology

However, this method has a large positioning error rate, and the text cannot be accurately positioned during use.

Chinese patent document CN110633027A also discloses a point reading method, system, computer equipment and storage medium. The method first acquires the image of the book, and then locates the finger through infrared recognition, so as to avoid the problem of identifying the finger position through the image. Inaccurate, but infrared positioning is affected by temperature, and the accuracy of its identification itself is not high
