A picture book recognition method based on image recognition and an invisible infrared ink technology

Abstract

The invention discloses a picture book recognition method based on image recognition and an invisible infrared ink technology. The picture book recognition method comprises the following steps of firstly, preparing the invisible infrared ink; 2, printing the invisible infrared ink at a specific position of a picture book; 3, using the camera to collects images; 4, carrying out graying on the acquired image, and removing a noise point effect; 5, carrying out binarization processing on the image; 6, positioning and inclination correction are carried out on the infrared image; 7, performing normalization processing on the QR code image subjected to binarization, positioning and correction; 8, performing error correction verification on the processed QR code image; 9, carrying out voice broadcast on the audio file. By applying the invisible infrared ink technology to picture book image recognition, the image recognition module can be prevented from being interfered by visible light illumination, the number information printed with the invisible infrared ink can be quickly recognized, the normal reading experience of a user is not influenced, and the picture book image recognition method has the comfortable and practical use value.

Description

technical field [0001] The invention relates to a picture book recognition method, in particular to a picture book recognition method based on image recognition and invisible infrared ink technology. Background technique [0002] Education is a popular industry where social capital and consumption gather today. According to data, the market size of China's education industry in 2018 exceeded 2.6 trillion, with the characteristics of high consumption level, long investment time and wide coverage; [0003] With the development of artificial intelligence technology and the improvement of people's living standards, products that apply artificial intelligence technology to children's early education and learning life are increasingly recognized by the market and parents; [0004] The picture book reading robot is a technological product incubated by emerging technologies. It is mainly based on image recognition technology, which collects, processes, and recognizes the image infor...

AI Technical Summary

Problems solved by technology

[0005] The current picture book recognition method mainly includes judging the page information by identifying the feature points of the picture book page image, and matching the corresponding audio file to play. This method is prone to low recognition accuracy for pages with little difference in picture book content and similar or similar screen features. The problem of confusion or error in the recognition results, and the problem of low recognition rate and wrong recognition caused by light interference;

[0006] The current picture book recognition method also includes determining the picture book file number by identifying the cover of the picture book, judging the page turning by monitoring the page turning action or recognizing the page number characters, and performing voice playback. There are many practical problems in this method, such as after cover recognition. Problems such as picture book replacement, missing content pages, a large number of page turning, and users blocking page numbers will all affect the accuracy of picture book recognition;

[0007] The current picture book recognition method also includes printing the page number on the page, determining the position of the page by identifying the number of each page, and then calling the voice information of the corresponding page from the memory for broadcasting. Although this method can Accurately locate the position and information of the page, but the number information will appear on the page of the picture book, which will affect the child's experience when reading the picture book
