Example is for the principle and its practical application of explaining the present invention, so that others skilled in the art are it will be appreciated that the present invention
Various embodiments and be suitable for the various modifications of specific intended application.In the accompanying drawings, identical label will be used for table all the time
Show identical element.
The detection means of the time delay of the VR glasses provided with reference to Fig. 1, Fig. 2, the present embodiment includes that photographic head 1, light is visited
Survey device 2, light source 5, the first fixed part and the second fixed part.Photographic head 1 is fixed on the first fixed part, and the second fixed part is used for solid
Determine VR glasses 4 and light source 5.Photographic head 1 is oppositely arranged with the display interface of VR glasses 4, and which is used for display circle for gathering VR glasses 4
The image in face.Second fixed part have light source 5 and photo-detector 2 just to first state and away from the second of photo-detector 2
State, the light intensity of light source 5 when photo-detector 2 is used to detect that VR glasses 4 are moved.
When VR glasses 4 are moved, the one movement therewith of the second fixed part, light source 5 also can be moved therewith together, when second solid
When determining portion and being changed between the first state and a second state, photo-detector 2 detects the light intensity of light source 5 and can change,
The change of light intensity is converted to the signal of telecommunication by photo-detector 2.When VR glasses 4 are moved, the image that photographic head 1 is collected is regarded
Angle can also change.
Wherein, the movement of VR glasses 4 includes moving left and right, move forward and backward and moving up and down.In order to more accurately to VR eyes
Detected the time delay of mirror, the moving direction of VR glasses 4 is different, the set location of photo-detector 2 is different.
Specifically, the detection means also includes support component 3.Support component 3 includes base 31, support shaft 32 and balance
Bar 33.Base 31 is circle, and support shaft 32 is column, and, perpendicular to base 31, the gimbal lever 33 is rotated with support shaft 32 and is connected for which,
Support axle 32 is used to support the gimbal lever 33 and the gimbal lever 33 is suspended from above base 31.Wherein, balance bar 33 in the horizontal plane around
Support axle 32 is rotated i.e. in the rotation with surface parallel to base 31.
First end 33a of first fixed part for the gimbal lever 33, second end 33b of second fixed part for the gimbal lever 33.Shooting

Step S1, the light intensity of detection light source 5, the image of the display interface of collection VR glasses 4；
Step S2, judge whether the light intensity changes, if changing, the moment that the light intensity is changed
It is designated as initial time；
Step S3, judge whether the visual angle of image changes, if changing, the visual angle of described image is occurred to become
The moment of change is designated as responding the moment；
Step S4, the time delay that the response moment and initial time work difference are obtained VR glasses 4.
The detection means and detection method of the time delay of the VR glasses 4 that the present embodiment is proposed, detection means include shooting
1 and photo-detector 2, the change of light intensity is detected by photo-detector 2 and initial time to be obtained according to light intensity change be Motion
Moment, by photographic head 1 gather VR glasses display interface image and according to described image obtain response the moment be Photon
At the moment, response moment and initial time are made into the time delay that difference just obtains VR glasses 4 then, so as to reduce detection time and
Detection difficulty, the degree of accuracy that improve detection.
The above is only the specific embodiment of the application, it is noted that for the ordinary skill people of the art
For member, on the premise of without departing from the application principle, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as the protection domain of the application.
