Description
Technical field
The present invention relates to a kind of visual rehabilitation training field, in particular to a kind of amblyopia training system and its application method.
Background technique
Amblyopia is the development of vision system obstacle disease due to caused by abnormal vision experience in the visual development critical period,
Feature is simple eye or eyes most preferably correct defects of vision low and are not accompanied by eye organic disease；Its pathogenic factors includes strabismus, bends
Beche-de-mer without spike is poor, height is ametropia and form deprivation.Amblyopia is to lead to the common eye disease of visual impairment, the trouble in population of China
Sick rate is about 3%, wherein children's myopia about 12,000,000.Amblyopia may accompany with patient all the life, it can be to patient in economy, the heart
Reason, society etc. bring huge burden, and expend a large amount of medical resource.Amblyopia has become one that everybody pays close attention to jointly
Social concern.
Occlusion therapy has been continued to use more than 200 years since de Buffon is put forward for the first time to treat amblyopia.It is till now
Only, occlusion therapy is still the most common method of clinical treatment amblyopia.But since the compliance of occlusion therapy itself is bad, shadow
The limitation of infant appearance and psychology is rung, scholars attempt to find another alternative.Atropine penalization using Ah
Tropine medicament for the eyes constrains preferable eye in conjunction with strong or excessively strong eyeglass is owed, and can be used for not receiving clinically occlusion therapy or occlusion therapy loses
The infant lost.But for example dizziness, dry, convulsions, excited, irritated, flush etc. can not for the drug side-effect of atropine itself
It avoids completely, glare problem is brought after mydriasis, paralysis accommodation is brought after cycloplegia, close, influence study cannot be regarded, and
And on long terms, more ultraviolet lights can not be estimated into the intraocularly influence to cataract and retinal disease after mydriasis, so,
Clinically, atropine penalization is not intended as amblyopia treatment method preferred and being used for a long time.
Since clinically amblyopia generally wants early detection and treatment just effective, occlusion therapy is generally not used for above the average age for marriage youngster
It is virgin and adult；And for 13 years old or more amblyopia patient, there is no direct and conclusive evidences to show that occlusion therapy is effective.In
It is that it is high and to the effective treatment method of above the average age for marriage amblyopia that scholars have been devoted to find safety, compliance.
The prior art is insufficient:
1. existing amblyopia training is all based on two dimensional image and stimulates patient's optic nerve, however two dimensional image compares
Dry as dust, patient's attention is not easy to concentrate, to influence training effect.
2. two equalization points, i.e. two visual differences can not accurately be measured, to influence training effect.
Summary of the invention
The present invention is intended to provide a kind of amblyopia training system and its application method are obtained more with more accurate means of testing

Equalization point reduces the brightness or contrast of the preferable eye picture of eyesight, allows patient to put on 3D glasses viewing video and is trained, specifically
Contrast control the following steps are included:
B1. obtain average brightness (or RGB with intermediate grey values 127 replace, as the space HSI is taken with 0.5 times of maximum brightness
Generation)；
B2. every compared with average brightness, it is (simple a kind of for by colour picture this step there are two types of method to obtain difference
Rgb value made the difference respectively with 127, it is complicated a kind of for rgb value to be first transformed into other HSI color space, I (intensity,
Strength component) it is made the difference with 0.5, H (Hue, tone) S (Saturation, color saturation) is constant, can keep tone not in this way
Become)；
B3. new brightness=(coefficient is obtained average brightness+coefficient (coefficient is less than 1) * difference by correction before；Rgb value
If the directly substitution of average brightness 127 be calculated, HSI can only obtain new I value in this step, be reduced into RGB will by HSI and
The transformation for mula of RGB is being calculated in next step)；
B4. according to new brightness, inverse operation calculates new R, G, and B value replaces the image RBG value before adjusting to be shown
Show.
