Embodiment 1

[0099] In order to make the determined text more accurate, whether there is a preset target gesture for writing in the current frame image in the video stream collected by the detection camera includes:

[0100] According to the current frame images in the video streams respectively collected by the two cameras, determine the overlapping area in the two current frame images; detect whether there is a preset target gesture for writing in the overlapping area;

[0101] The determining the coordinate information of the target gesture includes:

[0102] A first three-dimensional coordinate of the target gesture is determined according to the overlapping area.

[0103] The character recognition method provided by the embodiment of the present invention is applied to an electronic device, and the electronic device includes at least two cameras, and there is an overlapping area in image frames captured by the at least two cameras.

[0104] The embodiment of the present invention per...

Embodiment 2

[0133] On the basis of the above-mentioned embodiments, in the embodiment of the present invention, after determining the first three-dimensional coordinates of the target gesture, according to each coordinate information corresponding to the saved text to be output, determine the corresponding position of the text to be output. Before the target text, the method also includes:

[0134] According to the first three-dimensional coordinates, it is judged whether the current stroke is written;

[0135] If yes, proceed to next steps.

[0136] In the embodiment of the present invention, when the user writes a character, the target gesture for writing will always be in the overlapping area. When the user writes a character, he generally writes according to the strokes. After the stroke, when writing the next stroke of the character, the target gesture will not leave the overlapping area, then there is a target gesture in the overlapping area.

[0137] After every three-dimensional...

Embodiment 3

[0145] In order to facilitate users to check their own writing, on the basis of the above embodiments, in the embodiment of the present invention, after determining the first three-dimensional coordinates of the target gesture, the method further includes:

[0146] According to the mapping relationship between the pre-saved overlapping area and the writing display area of ​​the display screen, the first three-dimensional coordinates are mapped to the first two-dimensional coordinates of the writing display area, and according to the first two-dimensional coordinates in the writing display area.

[0147] In the embodiment of the present invention, there is a writing display area in the display screen of the electronic device, and the writing display area can display the user's writing situation. The mapping relationship between the overlapping area and the writing display area of ​​the display screen is stored in advance in the electronic device. According to the The mapping re...

Abstract

The invention discloses a character recognition method and device, an electronic device and a storage medium, which are used for solving the problems of inaccuracy and inconvenience in character inputting in the prior art. The method comprises the following steps: detecting if a preset target gesture for writing exists in a current frame image of a video stream acquired by a camera; determining coordinate information of the target gesture and saving the coordinate information if so; and determining a target character corresponding to a character to be outputted according to the saved coordinate information corresponding to the character to be outputted, and outputting the target character corresponding to the character to be outputted. As the electronic device determines the character written by the user according to the each three-dimensional coordinate of the target gesture hen the user writes in the air, quick and accurate inputting of the character can be achieved.

Description

technical field [0001] The invention relates to the technical field of character recognition, in particular to a character recognition method, device, electronic equipment and storage medium. Background technique [0002] With the advancement of science and technology and society, people's living standards continue to improve, and various electronic devices gradually enter people's lives, providing users with various conveniences. [0003] Existing electronic devices generally input text through a keyboard or a touch screen when inputting text for inputting information. However, many people in life are not proficient in keyboards enough, and the speed of entering text through keyboards is very slow. The touch screen of the electronic device is easily damaged or insensitive, which causes a lot of inconvenience for the user when inputting text through the touch screen. [0004] Users are generally very familiar with text writing. How to use this advantage to input text quick...
