Embodiment 1

[0050] figure 1 It is a flow chart of a character selection method provided by Embodiment 1 of the present disclosure. This embodiment can be applied to point reading by fingers in a point-reading environment. The method can be executed by a character selection device, which can be controlled by hardware and / or software, and can generally be integrated into electronic devices such as mobile phones, tablets, and computers. Specifically include the following steps:

[0051] S110. Obtain the position of the touch point of the user's finger on the point-to-read material, and identify candidate characters within a preset size area directly in front of the touch point position.

[0052] Point-of-view materials can be, for example, books, newspapers and picture books. The user clicks the text of the point-to-read material on the point-to-read material with a finger to perform point-reading. The specific point-reading process can be: the camera of the point-to-read device acquires t...

Embodiment 2

[0061] image 3 It is a schematic flowchart of a text acquisition method provided in Embodiment 2 of the present disclosure. This embodiment is embodied on the basis of each optional solution in the foregoing embodiments. Specifically include the following:

[0062] S210. Acquire finger width information of the user.

[0063] The finger image data is acquired through the camera, the outline of the finger is extracted, and the width information of the finger is determined according to the outline of the finger.

[0064] S220. Obtain information about the height of characters in the point-to-read materials.

[0065] By acquiring the image data of the point-to-read materials, the height information of the characters is determined according to the pre-acquired size of the point-to-read materials and the pixel ratio of the characters at the position of the finger in the image data of the point-to-read materials.

[0066] S230. Determine a preset size of an area according to the...

Embodiment 3

[0072] Figure 4 It is a schematic flowchart of a text acquisition method provided in Embodiment 3 of the present disclosure. This embodiment is embodied on the basis of each optional solution in the foregoing embodiments. Specifically include the following:

[0073] S310. Acquire the position of the touch point of the user's finger on the point-to-read material, and identify candidate characters within a preset size area directly in front of the touch point position.

[0074] S320. Determine the first marked text, where the first marked text is the closest text among the candidate texts to the position of the touch point.

[0075] Take the middle position of the fingertip as an example for the position of the contact point. The text marked for the first time is the text closest to the middle position of the fingertip, and the marking method is enlarged. The text marked for the first time can be enlarged or not, which is the default for text selection. initial position.

Abstract

The disclosure discloses a character selection method, device, point reading device, electronic device and storage medium. The method includes: obtaining the position of the touch point of the user's finger on the reading material, and identifying the candidate characters in the preset size area directly in front of the position of the touch point; detecting the change of the user's wrist, and determining according to the change of the wrist For the text marked in the preset size area, the position of the contact remains unchanged. The embodiment of the present disclosure can realize preliminary determination of candidate characters through fingers, determination of marked characters through wrist changes, and the marked characters are the final point-read characters. Compared with using point-reading pens, the point-reading process is simplified and the point-reading efficiency is improved. Enhance the ease of use and reliability of point-of-view devices.

Description

technical field [0001] Embodiments of the present disclosure relate to image acquisition technology, and in particular to a character selection method, device, point-reading device, electronic device, and storage medium. Background technique [0002] The point-reading device is an auxiliary teaching device, which transforms written textbooks into audio textbooks that can make sounds. At present, all point-reading devices need to use a point-reading pen for point-reading. The point-reading pen is easily lost, damaged, and out of power during point-reading, which makes the point-reading device unusable and has poor reliability. Contents of the invention [0003] The present disclosure provides a character selection method, device, point-reading device, electronic device and storage medium to solve the problem that the current point-reading pen is easily lost, damaged and out of power, so that the reliability of the point-reading device is poor. [0004] In the first aspect,...
