Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and specific embodiment party
Formula, is described in further detail the present invention.It should be appreciated that detailed description of the invention described herein is only in order to solve
Release the present invention, do not limit protection scope of the present invention.
As it is shown in figure 1, the net cast method for recording of a kind of interaction classroom of the present invention, comprise the steps:
Upper class hour, by least one video input device typing speaker or/and pay attention to the class the video record information of people, with
Time by least one microphone typing speaker or/and pay attention to the class the audio recording information of people；
During video record, by least two video input device typing speaker or/and pay attention to the class the video of people
Information, according to matching degree or the instruction of default video image, selects the video information of one of them video input device for regarding
Frequently recorded information.
When the net cast method for recording of this interaction classroom uses, upper class hour, recorded by least one video input device
Enter speaker or/and pay attention to the class the video record information of people, simultaneously by least one microphone typing speaker or/and pay attention to the class people
Audio recording information；During video record, according to the positional information of speaker, adjust the typing angle of video input device
Degree, and then can teacher be attended class and to carry out video interactive live for student's interaction classroom activity, can improve paying attention to the class of attending class online
The learning interest of people and enthusiasm, also can record into video and be available for other people and download study.The net cast of this interaction classroom is recorded
Method can the omnidistance process recording interaction classroom, and it is live to be carried out Online Video, or records into video and be available for other people study,
Improve the interest of online classes.
As in figure 2 it is shown, the net cast method for recording of this interaction classroom is additionally included in before attending class, by least two video
Input device is arranged at default fixed position, and the image by one of them video input device acquisition speaker is initial
Image, can arrange video input device in multiple positions as required, it is ensured that omnidistance without dead angle recording, simultaneously by one of them
It is initial pictures that video input device obtains the image of speaker, it is simple to the follow-up images match automatically controlled；Further, exist
During video record, all video input devices obtain the video image of a speaker and respectively by all speakers'
Video image mates with initial pictures respectively；When wherein a video image is the highest with the matching degree of initial pictures, should
Video information corresponding to video image is preferably video record information, it is thus achieved that the optimization of video record information, obtains
Obtaining best video recorded information, the picture improving online living broadcast interactive substitutes into sense；Further, described initial pictures is speaker
The direct picture of people, when images match, preferably carries out facial image information coupling；Face's figure when a wherein video image
As the facial image information matching degree of information and initial pictures is the highest and the matching degree of this facial image information is more than or equal to the
During one preset value, video information corresponding to this video image is preferably video record information；Face when a wherein video image
Image information the highest with the facial image information matching degree of initial pictures and this facial image information matching degree in portion's is less than first
During preset value, carry out whole matching according to described direct picture and video image, be arranged as required to priority match image, improve
Images match efficiency, the matching degree of this first preset value can be 95%, 90%, 85% or 80% etc., the process of video image and
The concrete mode of video image contrast coupling can be achieved by the prior art, and does not repeats them here；Face image is utilized to carry out
Preferential identification, makes the typing video between multiple video input device quickly can know according to the facial image information of speaker
Do not switch；The most in the process, it is also possible to the second preferred rank is set, such as the typing video model according to this video input device
Enclose area, whether have initial pictures in being automatically positioned at this typing range of video, preferably the video information of this video input device
The common factor of the typing range of video being in two or more video input devices for video record information, such as speaker can be adopted
Handsome choosing is carried out, it is thus achieved that optimum video record information by the preferred rank of above-mentioned face recognition.Further, this video input device
It is preferably monopod video camera, speaker can be passed through according to speaker or pay attention to the class the positional information of people and adjust its camera angle simultaneously
Or the facial image information paying attention to the class people adjusts its focal length automatically, it is ensured that the video image clarity of acquisition.
As it is shown on figure 3, the net cast method for recording of this interaction classroom also includes receiving the audio frequency that described microphone sends
The microphone of the signal of telecommunication, described microphone is received audio electrical signal and exports corresponding audio-frequency information, being carried by this public address set
High speaker or pay attention to the class the sound intensity of people, enters inputting audio information by this microphone, it is to avoid this public address set is sent out simultaneously
The audio-frequency information interference gone out.
As shown in Figure 4, during video record, also include receiving the first instruction when one of them video input device
Time, the video information of this video input device typing is preferably video record information, by multiple video input devices from polygonal
Degree typing speaker is or/and pay attention to the class the video information of people, and speaker passes through the remote controller more preferable video of free handoff angle simultaneously
Input device carries out typing speaker or pays attention to the class the video record information of people.Further, during video record, also include
When one of them microphone receives the second instruction, the audio-frequency information of this microphone typing is audio recording information, it is simple to main
Say that people passes through remote controller and freely switches typing speaker or pay attention to the class the audio recording information of people.
Described video input device included Portable image pickup head, upper class hour, paid attention to the class people by this Portable image pickup head typing
Video record information, it is simple to from the video record information paying attention to the class people of the angle typing of speaker Yu its face-to-face exchange.Again
Further, described microphone includes the first microphone and the second microphone, and upper class hour, by the first microphone typing speaker
Audio recording information, paid attention to the class the audio recording information of people by the second microphone typing；When the second microphone receives the 3rd
During instruction, start inputting audio recorded information；When the second sensor receives the 4th instruction, stop inputting audio and record letter
Breath, it is simple to from the audio recording information paying attention to the class people of the angle typing of speaker Yu its face-to-face exchange, freely switches and needs record
The audio recording information paying attention to the class people entered.
As it is shown in figure 5, the net cast recording system of a kind of interaction classroom of the present invention, including controlling device 100；
At least one rotating video input device 200, video input device 200 is arranged at default fixed position, and video typing fills
