Device 170 is arranged at camera 140, for obtaining the angle value of camera 140 in real time, and angle value is sent into controller
120；Controller 120 receives the angle value, specifically, and camera 140 can be calculated according to the angle value before adjustment to be needed to adjust
Whole angle, and whether be adjusted in place according to the angle value monitoring camera 140 after adjustment.
Fig. 5 is scheme of installation of the acceleration transducer at camera, and mark 570 is acceleration transducer, mark in figure
It is camera veneer to know 541, and acceleration transducer 570 is fixedly installed on camera veneer 541, by the acceleration for monitoring z-axis
Component acc_z is spent, according to formula acc_z=1g*cos θ, the angle of rotation is calculated, to determine whether camera rotate in place.
Preferably, the system also includes suggestion device 180 (see Fig. 2), and suggestion device 180 is connected with control device.
Controller 120, is additionally operable to the angle of visual field according to camera 140 and the altitude range of goal activities, judges that target is
It is no excessively near apart from camera 140, cause the altitude range of goal activities to exceed the angle of visual field of camera 140, if being judged as YES,
Hint instructions are sent to suggestion device 180.Suggestion device 180, the hint instructions for receiving the transmission of controller 120, sends mesh
The near prompt message excessively of subject distance camera 140.
As shown in figure 3, the suggestion device 180 is warning light 380, when CPU320 judges participant in game apart from camera
340 it is excessively near when, send hint instructions control the warning light 380 light, point out participant in game now apart from the mistake of camera 340
Closely.
Fig. 6 is that camera angle of the present invention adjusts the schematic diagram that system carries out angle adjustment with target movement to camera.
As shown in fig. 6, bottom scene be participant in game erect-position apart from camera remote position, now camera, which is fully met, catches
The requirement of participant in game action is obtained, angle is without adjustment.With the progress of game, participant in game leaves the distance of camera
Somewhat become near some, as shown in Fig. 6 mid-scenes, now camera has been not enough to the dynamic of capture participant in game completely
Make, such as when participant in game lifts the game paddle in hand, its height alreadys exceed the visual angle that camera can reach,
Now, camera angle adjustment system can calculate adjustment angle according to the distance of participant in game, and adjustment camera meets capture
It is required that.If likewise, participant in game has been arrived apart from camera closer proximity, as shown in uppermost scene in Fig. 6, taken the photograph
As needed for being recalculated head system for regulating angle adjust angle and complete adjustment, with meet capture require.
So, by the way that in whole game, the distance of measurement participant in game and camera changes, and is changed according to the distance
The angle for needing to adjust is calculated in real time, is dynamically adjusted the angle of camera, can be met the action capture range of camera, carry
Rise the experience effect entirely played.
Disclosed herein as well is a kind of virtual reality system, the virtual reality system is provided with for catching target action
Camera, and the as above camera angle adjustment system shown in any one, during target action, pass through camera angle
The luffing angle of adjustment system adjust automatically camera, makes the altitude range of the angle of visual field coverage goal activity of camera, catches
The action of target, to be mapped in virtual reality scenario.
Disclosed herein as well is a kind of camera angle method of adjustment, wherein, camera is used for the action for catching target, should
Method includes：
Step S710：Obtain target and the horizontal range of camera.
Step S720：According to the altitude range and horizontal range of goal activities, the angle of visual field coverage goal of camera is obtained
The altitude range of activity needs the angle adjusted.
Step S710：The luffing angle of camera is adjusted, makes the altitude range of the angle of visual field coverage goal activity of camera,
Catch the action of target.
The embodiment of this method may be referred to as above adjust camera angle the narration of system, no longer go to live in the household of one's in-laws on getting married herein
State.
The foregoing is only a specific embodiment of the invention, under the above-mentioned teaching of the present invention, those skilled in the art
Other improvement or deformation can be carried out on the basis of above-described embodiment.It will be understood by those skilled in the art that above-mentioned tool
The purpose of the present invention is simply preferably explained in body description, and protection scope of the present invention should be defined by scope of the claims.
