Embodiment 1

[0044] The embodiment of the present invention provides a recording and broadcasting system based on blackboard 1, such as figure 1 Shown, comprise: blackboard 1, the first pan-tilt camera 11, the second pan-tilt camera 12, the first recording equipment 13, the second recording equipment 14 and controller 18, specifically, the first pan-tilt camera 11, the second pan-tilt camera Two pan-tilt cameras 12 , a first recording device 13 and a second recording device 14 are integrated in the blackboard 1 .

[0045] exist figure 1 Among them, blackboard 1 is installed on the wall of classroom 2. Blackboard 1 here can be a smart blackboard in teaching, which can be used for multimedia teaching. The black glass light guide plate can be used to display multimedia courseware, and can also be used for teachers to conduct Blackboard writing, the blackboard 1 in the present embodiment is usually installed on the body of wall, can save the occupied space of classroom 2, simultaneously, the ...

Embodiment 2

[0053] The embodiment of the present invention provides a shooting method, which is used in the recording and broadcasting system based on the blackboard 1 in Embodiment 1, such as Figure 4 shown, including the following steps:

[0054] Step S1: Construct a triangle model according to the target person 3, the first PTZ camera 11 and the second PTZ camera 12. Such as Figure 5 As shown, the target person 3 is located in the middle of the classroom 2, the first PTZ camera 11 is set as A, the second PTZ camera 12 is set as B, and the target person 3 is set as C. A, B and C are located in three spaces in space. Different position points, therefore, these three different position points A, B and C can form ΔABC, which is the triangle model in this embodiment.

[0055] Step S2: Calculate the first distance between the first PTZ camera 11 and the target person 3 and the second distance between the second PTZ camera 12 and the target person 3 according to the triangle model. Since...

Embodiment 3

[0082] An embodiment of the present invention provides a storage medium on which computer instructions are stored, and the steps of the method in Embodiment 2 are implemented when the instructions are executed by a processor. Also stored on the storage medium are the first distance, the second distance, the third side length 17, the first interior angle, the second interior angle and the third interior angle of the triangle model, the first rotation angle, the second rotation angle, the first initial position , the second initial position, the first vertical angle, the second vertical angle, the sound signal from the target person 3, and the like. Wherein, the storage medium may be a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM), a random access memory (Random Access Memory, RAM), a flash memory (Flash Memory), a hard disk (Hard Disk Drive, Abbreviation: HDD) or solid state disk (Solid-State Drive, SSD), etc.; the storage medium may also include a ...

Abstract

The invention discloses a blackboard-based recording and playing system, a shooting method, a storage medium and a recording and playing blackboard, and the blackboard-based recording and playing system comprises a blackboard, a first holder camera, a second holder camera, a first recording device, a second recording device and a controller. Wherein the first pan-tilt camera is arranged on the base; Second holder camera, Second holder camera, The first recording device and the second recording device can be installed at the top end of the back of a glass light guide plate of the blackboard. The first pan-tilt camera and the second pan-tilt camera which are embedded in the blackboard form double cameras, the double cameras are combined with the first recording device and the second recording device to carry out positioning shooting on the target person or the classroom in the classroom, the target person or the classroom can be shot rapidly and clearly, and the shooting effect can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a blackboard-based recording and broadcasting system, a shooting method, a storage medium, and a recording and broadcasting blackboard. Background technique [0002] With the development of teaching equipment, intelligent teaching recording and broadcasting systems have replaced traditional manual recording methods. For example, intelligent teaching recording and broadcasting systems are usually built with camera equipment, recording and broadcasting equipment, and blackboards. Among them, the blackboard is usually used for teachers to write on the blackboard or multimedia projection. By combining the blackboard with the image recognition and tracking technology of the intelligent teaching recording and broadcasting system, the audio and video information of classroom teaching and student speeches in the classroom scene can be recorded and played. [0003] At present, the tra...
