Embodiment 1

[0028] figure 1 The implementation flow of the point reading method provided by the first embodiment of the present invention is shown. For the convenience of explanation, only the flow chart related to the embodiment of the present invention is shown. The specific steps are described in detail as follows:

[0029] In step S101, the point-reading device acquires a partial image containing book features;

[0030] In this embodiment, the point-reading device is a handheld device, without a fixed support or panel, and images containing book features can be acquired during the movement of the handheld device. For example, the point-reading device is a point-reading pen equipped with a camera, which is light and portable, and is convenient for children to perform point-reading operations on books through the point-reading pen.

[0031] In this embodiment, book features include but not limited to color features of partial book page images, texture features of partial book page imag...

Embodiment 2

[0060] figure 2 The implementation process of Embodiment 1 of the present invention in practical application is shown, and the details are as follows:

[0061] In S201, feature points are extracted from the book image;

[0062] In this embodiment, the book image is obtained, and after feature points are extracted from the book image, the feature points and feature descriptors of the original book image are stored in the book feature library.

[0063] In this embodiment, some unique points in the image are extracted, and the unique points are used as feature points, and the feature points are used as objects to be compared. Wherein, the feature points include but not limited to hurris corner points and Shi-Tomasi corner points.

[0064] In this embodiment, the acquired book feature library is stored in a local storage system or a distributed storage system.

[0065] In S202, a feature point descriptor is established;

[0066] In this embodiment, the feature point descripto...

Abstract

The invention belongs to the technical field of point reading equipment, and provides a point reading method, device and equipment. The method comprises the steps that the point reading equipment obtains a local image containing book features; the book features are extracted from the local image; according to the extracted book features, feature matching is carried out on the extracted book features in a prestored book feature library, and the book feature library stores the book features and positioning information corresponding to the book features, wherein the positioning information comprises book pages where the book features are contained and position information of the book pages where the book features are contained; when the feature matching is successful, the positioning information corresponding to the extracted book features is called from the prestored book feature library, and according to the positioning information, the book pages where the extracted book features are contained and the positions of the book pages are positioned in real time. According to the point reading method, device and equipment, the pronunciation reading applicability and accuracy and user operation efficiency of the point reading equipment are improved.

Description

technical field [0001] The invention belongs to the technical field of point reading equipment, and in particular relates to a point reading method, device and equipment. Background technique [0002] At present, point-to-read devices are loved by children because they can make books read aloud in real time. More and more parents buy point-to-read devices for children, so that children can learn cultural knowledge as early as possible. The point-reading equipment includes a point-reading machine and a point-reading pen. The point-reading machine is compatible with the books issued by the school, such as language, mathematics, and foreign languages. The sound quality is good, and there are many functions for children to participate in the interaction. The point reading machine pronounces and reads the text, thereby realizing the point-reading function, and the point-reading pen can also pronounce and read the text by clicking the position with the text on the special book, re...
