Problems solved by technology

[0002] Hanyu Pinyin is an important tool for learning Chinese characters. However, the learning of pure Pinyin is abstract and boring. It is definitely a challenge for children who have just learned Pinyin, especially those who are lively and active and have trouble keeping their attention.
[0003] There are many types of existing pinyin learning application software, but children often experience the learning process by touching mobile devices. This kind of process lacks interactive experience, and long-term learning will cause great damage to children's eyesight

Embodiment 1

[0063]An embodiment of the present invention provides a pinyin card recognition method, which is applied to a terminal device including a processor and a camera, such as figure 1 As shown, the method includes and steps:

[0064] S11: Acquiring pinyin card images.

[0065] In actual implementation, the pinyin card recognition method provided by the embodiment of the present invention is generally executed on the processor side. Before the processor obtains the pinyin card, the user needs to select the corresponding pinyin card according to the prompt information of the pinyin learning content and place it in the Below the camera, the camera collects the image of the pinyin card and sends it to the processor.

[0066] Specifically, the above-mentioned pinyin learning content is set into different levels according to the degree of difficulty, or set according to the learning sequence of the Chinese textbooks, so that children users can achieve a gradual learning effect. For the...

Embodiment 2

[0077] Embodiments of the present invention provide a pinyin card recognition method, such as figure 2 As shown, the method includes the following steps:

[0078] S21: Acquiring pinyin card images.

[0079] Step S21 in this embodiment of the present invention is the same as step S11 in Embodiment 1, and will not be repeated here.

[0080] S22: Perform noise reduction processing on the Pinyin card image by adopting a bilateral filtering method.

[0081] After the pinyin card image is obtained, before it is recognized, a noise reduction process will be performed on the image. Specifically, through the detection of human skin color, the shadow area of ​​the hand left by the hand when picking and placing the pinyin card is determined, and then the brightness of the shadow area is supplemented, and the time when the hand recognizes the pinyin card is excluded by bilateral filtering interference. The noise reduction process allows users to experience the fun of a stable interac...

Embodiment 3

[0120] Embodiments of the present invention provide a pinyin card recognition device, such as Figure 5 As shown, the device includes: an image acquiring unit 51 , a content determining unit 52 , a judging unit 53 and a prompting unit 54 .

[0121] The image acquisition unit 51 is used to acquire the pinyin card image;

[0122] The content determining unit 52 is used for determining the pinyin card content according to the pinyin card image;

[0123] Judging unit 53 is used for judging whether the pinyin card content is the same as the preset learning content;

[0124] The prompting unit 54 is used to send out a correct placement prompt signal when the judgment result of the judging unit is Yes; and send a placement error prompt signal when the judgment result of the judging unit is No.

[0125] Wherein, the content determination unit 52 specifically includes:

[0126] The straight line detection module 521 is used to perform straight line detection on the pinyin card image, ...

Abstract

The invention provides a Pinyin card identification method, a Pinyin card identification device and a terminal device and belongs to the image identification technical field. The Pinyin card identification method includes the following steps that: a Pinyin card image is acquired; Pinyin card content is determined according to the Pinyin card image; whether the Pinyin card content is the same as preset learning content is judged; if the Pinyin card content is the same as the preset learning content, correct placement prompting signals are emitted; and if the Pinyin card content is different from the preset learning content, wrong placement prompting signals are emitted. With the method adopted, a Pinyin card arranged below a camera by a user can be identified, timely feedback is given, and the interaction of a learning process can be enhanced.
