A kind of intelligent-tracking positioning hostTechnical field
This utility model relates to electronic device field, particularly relates to a kind of intelligent-tracking positioning host.
Background technology
Existing track and localization main frame is mainly used in photographic head cradle head control and the switching in recorded broadcast classroom, it is achieved a series of tracking strategy, as teacher follow the tracks of, student stands feature, electronic whiteboard tracking etc..
Existing track and localization main frame is mainly used in common recorded broadcast classroom, follows the tracks of just for this classroom, it is impossible to other interactive classroom videos are tracked switching, therefore cannot meet the interactive recorded broadcast classroom quickly grown in recent years；Prior art mostly uses infrared location or teachers and students to wear location equipment, human body can produce harm for a long time, and wearable device is inconvenient, and preparation of attending class is comparatively laborious.
Summary of the invention
For the defect that prior art exists, the utility model proposes a kind of intelligent-tracking positioning host, it is possible to the intelligent-tracking under Interactive Teaching Mode can be realized, be specifically designed for the tracking switching under remote interactive teaching pattern.When interactive classroom have student stand answer a question time, the picture of recorded broadcast bishop room can automatically switch to the close-up shot of this student of this classroom, it is achieved the intelligence switching of student's camera lens between multiple classrooms.
For realizing above-mentioned functions, the utility model proposes a kind of intelligent-tracking positioning host, including video acquisition module, video processing module, image analysis module and instruction sending module；The positioning video information collected is transferred to video processing module coding by described video acquisition module, image after coding is received by image analysis module and analyzes generation instruction, and the instruction of generation is transferred to instruction sending module and by the rotation of the RS232 Interface Controller video camera of network and monopod video camera and switching.
Described video acquisition module includes 4 BNC input interfaces, receives SD network for location picture；Described instruction sending module includes 1 network interface and 2 RS232 serial ports, is rotated by network control photographic head and switches.
Beneficial effect
Compared with prior art, this utility model is for interactive recorded broadcast classroom, on original track and localization host function, add the function of intelligence switching interdynamic video, it is capable of when having other interactive classroom student station immediately, the picture that recorded broadcast classroom and other interactive classrooms are seen can automatically switch to the classroom, student place to this student's feature of standing, and stands the at most span mode that can automatically switch when there being multiple student.More meet the demand of interactive teaching and recorded broadcast.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As it can be seen, the utility model proposes a kind of intelligent-tracking positioning host of proposition, including video acquisition module, video processing module, image analysis module and instruction sending module；The positioning video information collected is transferred to video processing module coding by described video acquisition module, image after coding is received by image analysis module and analyzes generation instruction, and the instruction of generation is transferred to instruction sending module and by the rotation of the RS232 Interface Controller video camera of network and monopod video camera and switching.
Described video acquisition module includes 4 BNC input interfaces, receives SD network for location picture；Described instruction sending module includes 1 network interface and 2 RS232 serial ports, is rotated by network control photographic head and switches.
: BNC input interface, it is used for gathering Teacher view image in accompanying drawing 2 3.；4.: BNC input interface, for gathering orientation of student 1 image, 5.: BNC input interface, for gathering orientation of student 2 image, 6.: BNC input interface, it is used for gathering writing on the blackboard network for location picture, 7.: RS232 serial ports 1, for connecting control teacher's feature photographic head, 8.: RS232 serial ports 2, it is used for connecting control student's feature photographic head.
This track and localization main frame, except basic recorded broadcast classroom tracking strategy, mainly adds the intelligent-tracking under Interactive Teaching Mode, is specifically designed for the tracking switching under remote interactive teaching pattern.When interactive classroom have student stand answer a question time, the picture of recorded broadcast bishop room can automatically switch to the close-up shot of this student of this classroom, it is achieved the intelligence switching of student's camera lens between multiple classrooms.Stand the at most span mode that can automatically switch when there being multiple student.More meet the demand of interactive teaching and recorded broadcast.
This utility model has also used the image recognition technology of advanced person, it is not necessary to Faculty and Students wear any tracking equipment, without harmful equipment such as installation infrared equipment, Energy and comfort, infrared location is not used yet, harmless, follow the tracks of by environmental disturbances less.Rely on the image gathered to be analyzed judgement and can realize all tracking strategy.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
