Problems solved by technology

[0003] In the existing online course video, because all the content of the blackboard writing in the teaching process is captured, some redundant data information is added to the video file, and the data volume of the teaching video is large, which leads to the occupation of memory by the video file of the online course. Too large, and the video traffic requirements are too high

Embodiment 1

[0027] figure 1 The flow chart of the method for recording the blackboard writing process provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the content of blackboard writing on the writing board is recorded. The method can be executed by a blackboard writing recording device, and specifically includes the following steps:

[0028] Step S110 , collecting voice information during the blackboard writing process, and collecting and saving blackboard writing images on the writing board based on a preset period.

[0029] Among them, the voice information is the teacher's detailed explanation of the content of the blackboard image during the teaching process, as well as the communication between the teacher and the students; What is written on the board. During the process of collecting blackboard writing images, voice information during the blackboard writing process is collected at the same time, and the blackboard writing imag...

Embodiment 2

[0043] figure 2 The flow chart of the method for recording the blackboard writing process provided by Embodiment 2 of the present invention. This embodiment is applicable to the situation where the content of blackboard writing on the writing board is recorded. The method can be executed by a blackboard writing recording device, and specifically includes the following steps:

[0044] Step S210, collecting voice information during blackboard writing and generating a time axis of the voice information.

[0045] In the process of collecting blackboard writing images, the corresponding voice information in this process is collected one by one, and the collection time of the voice information is saved at the same time, and the time axis is generated according to the collection time of the voice information.

[0046] Step S220, saving the initial blackboard writing image of the writing board, collecting temporary blackboard writing images of the writing board based on a preset peri...

Embodiment 3

[0058] image 3 It is a schematic structural diagram of a recording device for blackboard writing process provided by Embodiment 3 of the present invention. This embodiment is applicable to the case of recording blackboard writing content on a writing board. The recording device includes:

[0059] The collection module 310 is used to collect voice information in the blackboard writing process, and collect and save the blackboard writing image of the writing board based on a preset cycle;

[0060] A mapping module 320, configured to map the acquisition moment of the blackboard image to the time axis of the voice information;

[0061] The generation module 330 is configured to associate and store the voice information and the blackboard writing image based on the time axis, so as to generate a blackboard writing record file that continuously outputs the voice information and the blackboard writing image based on the time axis during playback.

[0062] As one of the implementati...

Abstract

The invention discloses a recording method, device, equipment and storage medium for blackboard writing process, comprising: collecting voice information in the blackboard writing process, and collecting and saving blackboard writing images of writing boards based on a preset period; collecting the blackboard writing images The moment is mapped to the time axis of the voice information; based on the time axis, the voice information and the blackboard writing image are associated and stored, so as to generate a blackboard recording record file that continuously outputs the voice information and the blackboard writing image based on the time axis during playback. The invention solves the problem that the data volume of blackboard recording files is too large, reduces the data volume of teaching videos and reduces the occupied memory of network course files.

Description

technical field [0001] The embodiment of the present invention relates to electronic teaching technology, and in particular to a recording method, device, equipment and storage medium for blackboard writing process. Background technique [0002] Online education is a product of the Internet age and a new field. Since it is not limited by time and region, more and more people learn through online courses. [0003] In the existing online course video, because all the content of the blackboard writing in the teaching process is captured, some redundant data information is added to the video file, and the data volume of the teaching video is large, which leads to the occupation of memory by the video file of the online course. Too large, and the video traffic requirements are too high. Contents of the invention [0004] The invention provides a recording method, device, equipment and storage medium for blackboard writing process, so as to reduce the data volume of teaching vi...
