Problems solved by technology

However, the teaching courseware cannot reflect the content written by the teacher on the teaching writing board, and often lacks practical information; the existing teaching video often captures the entire teaching process of the teacher, thus obtaining a large amount of teaching blackboard writing image
However, the obtained teaching blackboard images often include images that are repeated or have information occlusion, making it difficult for students to quickly filter out useful information for themselves

Embodiment 1

[0025] figure 1 A schematic flow diagram of a teaching blackboard image processing method provided in Embodiment 1 of the present invention, the method is suitable for screening and optimizing the teaching blackboard images captured during the teaching process, and the method can be executed by a teaching blackboard image processing device, wherein The device can be implemented by software and / or hardware, and is generally integrated on intelligent teaching equipment.

[0026] Such as figure 1 As shown, a method for processing a teaching blackboard writing image provided by Embodiment 1 of the present invention includes the following operations:

[0027] S101. According to the color feature value of the currently captured teaching blackboard image, determine whether there is an obstacle occlusion in the teaching blackboard image.

[0028] In this embodiment, the image of the teaching blackboard writing can be specifically understood as the teaching content written on the bla...

Embodiment 2

[0037] figure 2 It is a schematic flowchart of an image processing method for teaching blackboard writing provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention is optimized on the basis of the above-mentioned embodiments. In this embodiment, according to the image color feature value of the currently captured teaching blackboard image, it is determined whether there is an obstacle occlusion in the teaching blackboard image, which is further optimized as follows: Obtain the handwriting color feature value of the pre-stored handwriting on the blackboard and the base plate color feature value of the writing board itself; if the color feature value of the teaching blackboard image includes other colors except the handwriting color feature value and the base plate color feature value feature value, then determine the area size of the image area formed by the other color feature values; if the area size belongs to the set coverage area range, then...

Embodiment 3

[0078] image 3 It is a structural block diagram of an image processing device for teaching blackboard writing provided by Embodiment 3 of the present invention. The device is suitable for screening and optimizing the teaching blackboard images captured in the teaching process, the device can be implemented by software and / or hardware, and is generally integrated on intelligent teaching equipment. Such as image 3 As shown, the device includes: an occlusion determination module 31 , a relationship determination module 32 and a first processing module 33 .

[0079] Wherein, the occlusion determination module 31 is used to determine whether there is an obstacle occlusion in the teaching blackboard image according to the color feature value of the currently captured teaching blackboard image;

[0080]A relationship determining module 32, configured to determine the occlusion relationship between the obstacle occlusion and the handwriting on the blackboard when there is the obst...

Abstract

The invention discloses a teaching blackboard-writing image processing method and apparatus, an intelligent teaching device and a storage medium. The method includes the steps of determining whether there is obstacle occlusion in a teaching blackboard-writing image based on a color feature value of the currently captured teaching blackboard-writing image; if there is the obstacle occlusion, determining an occlusion relationship between the obstacle occlusion and the blackboard-writing; and according to the occlusion relationship, determining a processing operation corresponding to the teaching blackboard-writing image, the processing operation including a deleting operation and a saving operation. By this method, it is possible to determine the occlusion of the information in the captured teaching blackboard-writing image in real time, so as to determine whether to performing the saving or deleting operation on the teaching blackboard-writing image according to the determined result, thus, the purpose of optimizing and saving the information of the teaching blackboard-writing image is achieved, and a learner can be ensured to quickly filter useful information from the teaching information.

Description

technical field [0001] The invention relates to the technical field of electronic teaching, in particular to a teaching blackboard image processing method, device, intelligent teaching equipment and storage medium. Background technique [0002] In the tide of improving the classroom teaching environment with electronic educational equipment, the functions of teaching writing boards, such as electronic whiteboards and traditional blackboards provided by touch screen terminals, have not changed significantly. [0003] During the teacher's teaching process, if it is necessary to save teaching information data for students to review after class, it is generally saved by way of teaching courseware or video recording of the teaching process. However, the teaching courseware cannot reflect the content written by the teacher on the teaching writing board, and often lacks practical information; the existing teaching video often captures the entire teaching process of the teacher, thu...
