Problems solved by technology

But it cannot replace the traditional blackboard, because the electronic whiteboard cannot restore some details such as strokes, which may lead to poor viewing effect of the saved blackboard writing, especially for some courses that need to restore handwriting details, such as art, calligraphy, etc.
Moreover, the interference of auxiliary educational equipment (such as a triangle) cannot be ruled out. For example, when using a triangle to measure on a blackboard, the touch screen will misjudge that the triangle is the content of blackboard writing and display it, resulting in redundant content in the final displayed blackboard
[0003] However, traditional writing boards, such as blackboards and whiteboards, have a limited writing area and cannot be restored once erased. Therefore, students need to take notes quickly. If the area is not enough, the lectures will be suspended, which will slow down the teaching progress and affect the quality of education

Embodiment 1

[0023] figure 1 The flow chart of the teaching blackboard display method provided by Embodiment 1 of the present invention, this embodiment is applicable to the situation of using a writing board to write blackboard writing in the teaching classroom, the method can be executed by the teaching blackboard display device, and the method includes:

[0024] Step 110, collecting and saving blackboard writing images corresponding to each blackboard writing content on the writing board;

[0025] Step 120, confirming that the writing board begins to add a new blackboard writing content;

[0026] Step 130, displaying the image of the writing on the blackboard with the latest storage time on a display terminal adjacent to the writing board.

[0027] According to the above steps, when the teacher writes blackboard writing on the writing board, the display terminal will display the corresponding blackboard writing image of the previous blackboard writing, so that the teacher can erase the...

Embodiment 2

[0049] image 3 The flow chart of the teaching blackboard display method provided by Embodiment 2 of the present invention. This embodiment is applicable to the situation of using writing blackboard writing in the teaching classroom. This method can be executed by the teaching blackboard display device. The same steps as steps 110, 120 and 130, the difference is that for step 110, there are different specific implementations.

[0050] Specifically, in this embodiment, step 110 is specifically: when receiving a collection instruction triggered by a user's operation, collecting and saving the current blackboard writing content on the writing board to generate a blackboard writing image.

[0051] In this embodiment, the image acquisition work is triggered according to the user's operation, and the image collected each time is used as a blackboard writing image corresponding to a blackboard writing. That is, when the teacher needs to erase the writing on the blackboard to obtain ...

Embodiment 3

[0055] Figure 4 It is a schematic structural diagram of a teaching blackboard display device provided by Embodiment 3 of the present invention. The teaching blackboard display device includes:

[0056] The collection module 310 is used to collect and save the blackboard writing image corresponding to each blackboard writing content on the writing board;

[0057] A confirmation module 320, configured to confirm that a new blackboard content is added on the writing board;

[0058] The display module 330 is configured to display the blackboard writing image with the latest storage time on a display terminal adjacent to the writing board.

[0059] As one of the implementation manners, the collection module 310 includes:

[0060] A generating unit, configured to collect the current blackboard content on the writing board according to a preset frequency to generate a temporary image;

[0061] a calculation unit, configured to calculate the height of the blank writing range belo...

Abstract

The invention discloses a teaching blackboard writing display method, which comprises the following steps: collecting and storing a blackboard writing image corresponding to each board of blackboard writing content on a writing board; determining to add a new board of blackboard writing content on the writing board; and displaying the blackboard writing image, the storage time of which is latest, on a display terminal arranged adjacent to the writing board. Correspondingly, the invention discloses a teaching blackboard writing display device, equipment and a computer readable storage medium. The problem that, in the prior art, when a teacher cannot erase the blackboard writing content in time, writing area is not enough and teaching is interrupted is solved, and enlargement of the writing area is realized, so that the teacher is allowed to give a lesson in sequence according to plan, and teaching quality and effect are improved.

Description

technical field [0001] The invention relates to electronic teaching technology, in particular to a method, device, equipment and computer-readable storage medium for displaying teaching blackboard writing. Background technique [0002] Writing on the blackboard on the electronic whiteboard provided by the touch screen terminal has the advantages of no dust, effortless writing and easy erasure, so the electronic whiteboard is gradually popularized in the teaching classroom. But it cannot replace the traditional blackboard, because the electronic whiteboard cannot restore some details such as strokes, which may lead to poor viewing effect of the saved blackboard writing, especially for some courses that need to restore handwriting details, such as art, calligraphy, etc. Moreover, the interference of auxiliary educational equipment (such as a settable, etc.) cannot be ruled out. For example, when using a settable to measure on a blackboard, the touch screen will misjudge the se...
