Abstract
The invention discloses a kind of recording and broadcasting systems of intelligent instructor in broadcasting, student's panoramic camera, teacher's panoramic camera, pick up facility including being connected to recorded broadcast host, and student's speech feature video camera of recorded broadcast host is connected by tracking and identifying positioning host, further include mounting height be slightly above student sit up straight height, the horizontally disposed student of camera lens stand up tracking video camera, the student stand up tracking video camera by track and identify positioning host connect recorded broadcast host；When track and identify positioning host by student stand up tracking video camera recognized stand up student when, control student feature video camera alignment of making a speech is stood up student, and is key frame by the feature shot by camera screen switching of making a speech of the student in recorded broadcast host.The present invention is stood up by student tracks the plane that video camera shooting slightly above student sits up straight height, and the student that automatic identification takes the floor, control student's speech timely shooting picture of feature video camera does not limit student's quantity, can effectively reduce probability of failure.
Description
Technical field
The present invention relates to recording and broadcasting system fields, and in particular to a kind of recording and broadcasting system of intelligence instructor in broadcasting.
Background technology
Recording and broadcasting system is to record the picture at the scene such as teaching, meeting, performance by video camera for the system of reproduction；Teaching
Scene often has classroom interactions, recording and broadcasting system to shoot teacher's panorama, student's panorama, student speech spy respectively using multiple cameras
Equal pictures are write, non-interaction stage teacher's panorama, when there is student's speech, tracks and identifies positioning host and send out student as key frame
Speech feature is switched to key frame；Traditional recording and broadcasting system uses manual control screen switching, needs special messenger to give more sustained attention teaching existing
The situation of field, labor intensity is big, efficiency is low, and is easy to miss the picture of student's speech；There is one kind on trainee seat at present
Pressure sensor is installed and realizes the recording and broadcasting system automatically switched, judgement should when pressure sensor output valve is less than preset threshold value
Student on seat takes the floor, and control student feature video camera of making a speech is directed at the seat, and will be based on captured screen switching
Picture, when there is the seat free time, can cause student's speech feature to be taken the photograph its shortcoming is that student's quantity is required to be matched with numbers of seats
Camera is locked in idle seat, and when student's interim additional seat of more needs, interim seat is fitted without pressure sensor and can not
Be taken speech feature when student makes a speech, in addition, when there are many installation number of pressure sensor, the probability of failure is big
Width improves, and influences the normal operation of recording and broadcasting system.
Invention content
The technical problem to be solved in the present invention is to provide a kind of recording and broadcasting systems of intelligent instructor in broadcasting, can solve existing recorded broadcast system
System leads to limit student's quantity and the high problem of probability of failure using pressure sensor detection student's speech.
The invention is realized by the following technical scheme：
A kind of recording and broadcasting system of intelligence instructor in broadcasting, including be connected to student's panoramic camera of recorded broadcast host, teacher's panoramic camera,
Pick up facility, and student's speech feature video camera by tracking and identifying positioning host connection recorded broadcast host, further include installation
Height slightly above student, which sits up straight height, the horizontally disposed student of camera lens stands up tracks video camera, and the student, which stands up, tracks camera shooting
Machine connects recorded broadcast host by tracking and identifying positioning host；When track and identify positioning host by student stand up tracking video camera know
It has been clipped to when standing up student, control student feature video camera alignment of making a speech is stood up student, and the student in recorded broadcast host is made a speech
Feature shot by camera screen switching is key frame.
The further scheme of the present invention is that the student stands up tracking video camera side by side equipped with multiple.
The present invention further scheme be further include by track and identify positioning host connect recorded broadcast host teacher's writing on the blackboard
Video camera and teacher track video camera.
The further scheme of the present invention is that the recorded broadcast host is also connected with network, is accessed for client terminal and management terminal.
The advantages of the present invention over the prior art are that：
One, it is stood up by student and tracks the plane that video camera shooting slightly above student sits up straight height, what automatic identification took the floor
Student, control student's speech timely shooting picture of feature video camera, does not limit student's quantity, and it is several effectively to reduce failure
Rate；
Two, the range of bigger can be covered by being equipped with multiple students tracking video camera that stands up side by side, cover the institute in place comprehensively
There is student；
Three, teacher's writing on the blackboard video camera and teacher track video camera and shoot close up view in teacher's writing on the blackboard or while walking about, and effect is more preferable；
Four, it can be broadcast live by network or program request recorded content, using more convenient.
Description of the drawings
Fig. 1 is the camera schematic view of the mounting position of the present invention.
Fig. 2 is the system structure diagram of the present invention.
Specific implementation mode
The recording and broadcasting system of intelligent instructor in broadcasting as depicted in figs. 1 and 2 a kind of, including be connected to student's panorama of recorded broadcast host and take the photograph
Camera 2, teacher's panoramic camera 4, pick up facility and Computer for teachers, and connect recorded broadcast host by tracking and identifying positioning host
Student make a speech feature video camera 7, teacher's writing on the blackboard video camera 5 and the teacher of tracking video camera 3, student that stand up track video camera 6, institute
State student's panoramic camera 2, student stands up and tracks video camera 3 and student's speech feature video camera 7 mounted on classroom front, teacher
Panoramic camera 4, teacher's writing on the blackboard video camera 5 and teacher track video camera 6 and are mounted on classroom rear portion, and wherein student's tracking of standing up is taken the photograph
Camera 3 is equipped with multiple side by side in 1 both sides of blackboard of classroom front, and mounting height is slightly above student, and to sit up straight height, camera lens horizontal
Setting, the student stand up tracking video camera 3 by tracking and identifying positioning host connection recorded broadcast host；It is led when tracking and identifying positioning
Machine by student stand up tracking video camera 3 recognized stand up student when, control student 7 alignment of feature video camera of making a speech is stood up
Member, and be key frame by screen switching captured by student's speech feature video camera 7 in recorded broadcast host；The recorded broadcast host also connects
Network is connect, is accessed for client terminal and management terminal.
