Embodiment 1

[0038] figure 1 This is a schematic flowchart of Embodiment 1 of the recording and broadcasting method for classroom teaching according to the present invention. The method of this embodiment is applicable to a recording and broadcasting system for classroom teaching, such as figure 1 As shown, the method of this embodiment may include:

[0039] Step 101, receiving an alarm signal.

[0040] In this embodiment, the alarm signal is triggered when a detection module installed in the classroom, such as a detection camera or a detection sensor, detects a predetermined target in the classroom and generates a predetermined event. For example, the teacher detection camera triggers an alarm signal when the teacher walks onto the podium, the student detection camera triggers an alarm signal when it detects that a student stands up, and the blackboard writing detection camera detects that the teacher is writing on the blackboard and triggers an alarm signal, and so on.

Embodiment 2

[0065] figure 2 This is a schematic flowchart of Embodiment 2 of the recording and broadcasting method for classroom teaching according to the present invention. The method of this embodiment is applicable to a recording and broadcasting system for classroom teaching, such as figure 2 As shown, the method of this embodiment may include:

[0066] Step 201: Receive a first alarm signal, and update the pre-recorded alarm state corresponding to the first alarm signal to the latest state.

[0067] In this embodiment, the first alarm signal is triggered when the detection module detects that the first object in the classroom generates the first event.

[0068] Step 202: Receive a second alarm signal, and update the pre-recorded alarm state corresponding to the second alarm signal to the latest state.

[0069] In this embodiment, the second alarm signal is triggered when the detection module detects that the second object in the classroom generates a second event.

Embodiment 3

[0091] image 3 This is a schematic flowchart of Embodiment 3 of the recording and broadcasting method for classroom teaching according to the present invention. The method of this embodiment is applicable to a recording and broadcasting system for classroom teaching, such as image 3 As shown, the method of this embodiment may include:

[0092] Step 301: Receive a first alarm signal.

[0093] The first alarm signal is triggered when the detection module detects that a first object in the classroom generates a first event.

[0094] Step 302: Receive a second alarm signal.

[0095] The second alarm signal is triggered when the detection module detects that a second object in the classroom generates a second event.

[0096] Step 303: Determine the first video image to be broadcast.

[0097] In this embodiment, the first video image to be broadcast can be determined according to the first alarm signal and the pre-established third broadcast strategy. Wherein, the third broa...

Abstract

The embodiment of the invention discloses a recording and broadcasting method, device and system for classroom teaching and relates to the technical field of video recording and broadcasting, aiming to improve expandability and maintainability. The recording and broadcasting method for classroom teaching comprises the following steps of receiving an alarm signal, wherein the alarm signal is triggered when a detection module detects that a preset target in the classroom generates a preset event; determining a video image to be recorded and broadcast according to the alarm signal; determining whether a video acquisition camera for acquiring the video image exists or not; if the video acquisition camera exists, switching the video image into a directing channel, otherwise, abandoning the video image. The method, the device and the system are suitable for classroom video recording and broadcasting and remote teaching.

Description

technical field [0001] The invention relates to the technical field of video recording and broadcasting, in particular to a recording and broadcasting method, device and system for classroom teaching. Background technique [0002] The recording and broadcasting system is composed of a recording and broadcasting host, a detection module, and a video acquisition camera, which is used for classroom video recording and remote teaching. The recording and broadcasting host completes the functions of directing, transmission and recording; the detection module realizes the detection of teacher behavior, student behavior, writing on the blackboard, and the use of courseware; the video acquisition camera provides video images of teachers, students, courseware, and writing on the blackboard. [0003] In the existing recording and broadcasting system, the detection modules include a student detection camera, a teacher detection camera and a blackboard writing detection camera; the video...
