Technical field
The present invention relates to optometry technical field, more particularly to a kind of optometry method based on VR technologies.
Background technology
Traditional optometry unit is come the eye of optometry, i.e. measurement people using light path (a kind of optical device with particular community)
The eyeball number of degrees, corresponding axle position etc. when determining whether astigmatism and having astigmatism.Light path principle is that launched by one end of equipment can
See light, human eye is incided into after a series of concave-convex lens, corresponding reflection is then reflected by the pupil surface of human eye
Light, the reflected light pass through a series of concave-convex lens again, can finally pass through an aperture mirror light bar, thus can be in the other end of light path
It focuses on and forms a ring of light.For the eyes of the different number of degrees, the ring of light of different size degree can be formed, which is attached to light
Digital camera in road is received in post-sampling deposit memory, and optometry algorithm software is by analyzing oval ring of light size received etc.
Method measures the human eye number of degrees.
Traditional optometry unit measures the different number of degrees of human eye using the different size of obtained elliptical ring.This method
The advantages of be measurement it is more accurate, shortcoming but has very much；Such as, the degree of cooperation of heavy dependence human eye；Light path plus fuselage etc. its
His peripheral equipment, the weight about 25kg of optometry unit are clumsy, be not suitable for mobile optometry；Traditional optometry unit cost of manufacture is expensive, most
Also 1.5 ten thousand or so, the unsuitable whole people promote the use of cheap price.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of optometry method based on VR technologies, above-mentioned existing to overcome
Deficiency in technology.
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of optometry method based on VR technologies, including with
Lower step：
Step S1：Optometry test information is exported to user, the optometry test information includes multiple optometry special images；
Step S2：The optometry special image is shown successively, so that user picks out viewing the most clearly described in one
Optometry special image is target image；
Step S3：The corresponding human eye number of degrees of the target image are obtained from the database of VR systems.
The beneficial effects of the invention are as follows：By establishing associating between optometry special image and the human eye number of degrees in VR systems
Information, so as to pick out viewing by human eye, the most clearly optometry special image determines the human eye number of degrees for target image, with
Traditional optometry unit is compared, easy to use, it can be achieved that quickly and easily self-help refraction completely without using light path.
Further：The display order of optometry special image is sequentially increased suitable according to clarity described in the step S2
Sequence.
The advantageous effect of above-mentioned further scheme is：Special image is shown with clarity order, and sight is picked out beneficial to user
See target image the most clear.
Further：The display order of optometry special image is sequentially reduced suitable according to clarity described in the step S2
Sequence.
The advantageous effect of above-mentioned further scheme is：It is with clear that user can select optometry special image according to actual needs
It spends the order for being sequentially reduced or being sequentially increased to be shown, select more diversified.
Further：In the step S2 after user picks out the target image cleaned the most from optometry special image,
It can also be adjusted to adjust the target image to the position of the target image to viewing the most clearly state.
The advantageous effect of above-mentioned further scheme is：Ensure the accuracy of prescription.
Further：The relation being stored in the database of the VR systems between the position x of target image and human eye number of degrees y
Formula y=f (x), after the position that user further adjusts the target image reaches viewing the most clearly state, VR
System will calculate the number of degrees of human eye by y=f (x).
The advantageous effect of above-mentioned further scheme is：The clear image position seen by establishing human eye in VR systems
With the relational expression between the human eye number of degrees, so as to see the position of clear image by human eye to determine the human eye number of degrees, tested with tradition
Light instrument is compared, easy to use, it can be achieved that quickly and easily self-help refraction completely without using light path.
