Specific embodiment
The following detailed description of specific implementation of the invention, it is necessary to it is pointed out here that, below implement to be only intended to this hair
Bright further illustrates, it is impossible to be interpreted as limiting the scope of the invention, and art skilled person is according to above-mentioned
Some nonessential modifications and adaptations that the content of the invention is made to the present invention, still fall within protection scope of the present invention.
The invention provides one kind education cloud class outdoor scene drawing generating method and device, as shown in figure 1, the one of outdoor scene room
On side wall, main filming apparatus 2 are set, and with main camera head 2 for center of circle o sets up rectangular coordinate system.Fig. 2 be metope just
View, center of circle o points are located at the center position of metope, on same metope, the length in the horizontal direction of main filming apparatus 2
At the position of L, the first auxiliary filming apparatus 1 and the second auxiliary filming apparatus 3 are respectively arranged with, the length of L can be according to reality
The metope length in the outdoor scene room on border is selected, and preferably the value of L causes that the first auxiliary filming apparatus 1 and the second auxiliary are clapped
Take the photograph device 3 has 45% to be superimposed visual field with main filming apparatus 2 respectively.Main filming apparatus 2 are used as the master for educating cloud class realistic picture
Filming apparatus are wanted, with the shooting visual field bigger than obtaining the first auxiliary auxiliary filming apparatus 3 of filming apparatus 1 and second.Such as Fig. 1 institutes
Show, if being shot using main filming apparatus 2, then blind area A and B occurs, then can be using the first auxiliary
The shooting of the auxiliary filming apparatus 3 of filming apparatus 1 and second is compensated, and aids in clapping by the first auxiliary filming apparatus 1 and second
Take the photograph device 3 and shoot blind area A and part B in realistic picture, the part and the first auxiliary in the realistic picture that main filming apparatus 2 are shot are clapped
Taking the photograph blind area A and part B in the auxiliary shooting realistic picture of filming apparatus 3 of device 1 and second carries out image mosaic, can so ensure not
In the case of changing enlarged drawing shooting multiple, the whole realistic picture of comprehensive covering so that the outdoor scene plot quality of shooting is more excellent.
Traditional filming apparatus are directly directly to be shot according to the position of people, although this mode can in real time with
Track, but the adjustment of shooting angle and position cannot be carried out according to the action of the details of personage, and the effect for so shooting will beat greatly
The position of discount, such as personage is constant, but action there occurs change, and the angle of shooting can change, and now due to taking the photograph
As device is not adjusted so that the pith in the picture of shooting may be blocked.
Therefore, the teacher that imparted knowledge to students in the present invention also wears follow-up mechanism, and the structure of follow-up mechanism is as shown in figure 3, including inertia
Element accelerometers, gyroscope and altimeter, and be connected with microprocessor respectively, microprocessor is also connected with wireless communication device.
Firstly, it is necessary to follow-up mechanism is positioned over carry out initial calibration at the o of the center of circle, accelerometer, gyroscope can be just utilized after calibration
Measure the positional information of follow-up mechanism in real time with altimeter.Traditional accelerometer, gyroscope and altimeter are commonly used to survey
Real-time velocity information, angle information and elevation information are measured, position herein is directly obtained using these information.And present invention profit
With accelerometer, gyroscope and altimeter still for the real-time velocity information of MEASUREMENT TEACHING teacher, angle information and height
Information, but these information need not be utilized to obtain the positional information of teaching teacher, but directly measure these parameters
After being processed by microprocessor afterwards, sent to wireless receiver by wireless communication device and received.As shown in figure 4, control
Processor processed connects transceiver, driver element, the auxiliary filming apparatus 1 and second of main camera head 2, first and shoots dress respectively
3 are put, after velocity information, angle information and elevation information that transceiver real-time reception sends from wireless communication device, is passed through
Control process device is calculated, the velocity information, angle information and the elevation information that are received by previous moment and current time
Velocity information, angle information and the elevation information for receiving, obtain the bearing variation value A of follow-up mechanism, and when utilizing previous
Carve and the speed of later moment in time is worth to speed difference △ V, determine regulation coefficient B.
As shown in Fig. 2 the in the vertical direction of 1 and second filming apparatus of the auxiliary filming apparatus of main camera head 2, first 3 can
Can also be adjusted with the shooting angle of movement, and the auxiliary filming apparatus 3 of filming apparatus 1 and second of main camera head 2, first
Whole, specific adjustment mode can be realized using head is carried, or directly be realized by changing lens direction.So root
Main camera head 2, first auxiliary filming apparatus 1 and second count just can be in real time adjusted according to the orientation angles changing value A for obtaining
The visual field orientation of device 3 is taken the photograph, so as to record in real time, generation education cloud class realistic picture.It should be noted that in real-time adjustment
During, adjust the speed degree of change, i.e., the auxiliary filming apparatus 1 and second of main camera head 2, first are adjusted in real time to be shot
If the time selection in the visual field orientation of device 3 is improper, the phenomenons such as smear occur, therefore the invention further relates to optimization
Visual field adjustment time removes the phenomenons such as the smear being likely to occur.Specifically, shooting dress according to the auxiliary of main camera head 2, first
Put 1 and second filming apparatus 3 performance setting unit adjustment time t, be worth to using the speed of previous moment and later moment in time
The regulation coefficient B that speed difference △ V determine is multiplied with unit adjustment time t and can be obtained by this adjustment time section, so that
Clapped with the main auxiliary of camera head 2, first of average rate control adjustment in adjustment time section using control process device control driver element
Take the photograph the adjustment that 1 and second filming apparatus of device 3 complete visual field orientation, generation education cloud class realistic picture.
Educating the content of cloud class realistic picture may dabble different themes, such as hot news, curricular system, bear child system
The multiple plate such as row, home circle, data center, activity centre, such as data center can provide pass for numerous infant teachers
Educate altogether in child-care center's management, education activities, outdoor activities, home, the document resources such as life on the one, and activity centre can be then excellent
The related content video such as elegant demonstration class.
