Description
Technical field: present invention relates particularly to a kind of methods for making visual chart using color range legal system.
Background technique: the vision testing method of world wide letter is designed according to the principle at visual angle at present: by extraneous two o'clock
The light of sending is formed by angle through intraocular node.Under normal circumstances, human eye can tell the minimum range institute shape of point-to-point transmission
At visual angle be minimal visual angle, i.e. one point of visual angle.Visual chart is exactly to be designed as unit of one point of visual angle.Referring to national standard GB
11533—1989。
Exterior object, the readability observed, in addition to foreign objects are as the folder that node is formed within the eye are observed by eyes
Outside angle, also it is positively correlated with the readability of image received by eyes, and readability is then by eyes perceptible as face
The color difference size of color is distinguished.
Summary of the invention:
Goal of the invention: the purpose of the present invention is to provide a kind of sides of visual chart for being made and being given a test of one's eyesight using color difference
Method, and the method for making of color difference sight tester.
Technical solution:
A method of making visual chart using color range legal system, it is characterised in that:
In the method, if:
Bc (i) is the background color value of the i-th row sighting target on visual chart, i.e. paper or display face around the i-th row sighting target
Color value；

This method includes the following steps:
Step 1: visual chart totally 11 row sighting target, serial number is respectively 0,2 from top to bottom ..., and 10；The size of each row sighting target is protected
Hold it is constant, it is different according to the designed distance of visual chart, in sighting target size and GB 11533-1989 0.12 or 0.15 or 0.2 or
Sighting target size corresponding to 0.25 eyesight is identical；Bc (i) and Ec (i) change between each row；
Step 2: for black and white color difference visual chart, set visual chart Bc (0) value and Ec (0), Bc (0)=RGB (255,
255,255), Ec (0)=RGB (0,0,0)；Then according to formula (1), Cd (0)={ 255,255,255 } are obtained；
Step 3: three component values { Cd (10) r, Cd (10) g, Cd (10) b } of setting visual chart Cd (10), for black and white
Colour difference acuity table, which is { 2,2,2 } or value is { 1,1,1 }, { 3,3,3 } or { 4,4,4 }；
Step 4: setting visual chart Bc (10) value；For black and white color difference visual chart, the value be set as RGB (192,192,
192), Bc (10) is optional in the section [RGB (Cd (10) r, Cd (10) g, Cd (10) b), Bc (0)]；
Step 5: according to Step 2: three, four setting, determine CdIr value and Cd (i) value；If the value of Cd (10) is
{ 2,2,2 }, then according to formula:

Cd (i)=Cd (0) * CdIri (2)
Each Cd (i) value is found out, the value interval of i is [0,10]；
Step 6: according to Step 2: three, four setting, determine BcIr value and Bc (i) value；If Bc (10) value is RGB
(192,192,192), then according to formula:
Bc (10)=Bc (0) * BcIr10
Find out BcIr value, BcIr=0.972；Then, according still further to formula:
Bc (i)=Bc (0) * BcIri (3)
Each Bc (i) value is found out, the value interval of i is [0,10]；
Step 7: visual chart is generated on printed matter or display device；Assuming that the i-th row, according to formula (2) and formula (3)
Show that Bc (i) and the value of Cd (i) are respectively as follows:
Bc (i)=RGB (Bcr, Bcg, Bcb), Cd (i)={ Cdr, Cdg, Cdb } then find out Ec (i) according to formula (1):
Ec (i)=RGB (Bcr-Cdr, Bcg-Cdg, Bcb-Cdb)
Then obtain each row parameter of black and white color difference visual chart；
Step 8: the colour difference acuity table design for other colors, CdIr, BcIr and initial row Ec (0) and black and white color difference
Parameter used in visual chart is identical, and difference is only initial row Bc (0) value:
For black and white color difference visual chart: Bc (0)=RGB (255,255,255)；Eyesight label are as follows:
0.15W,0.2W,0.25W,0.3W,0.4W,0.5W,0.6W,0.8W,1.0W,1.2W,1.5W；

Only see depending on eye and is entirely clear control sighting target, and Second eye is only capable of seeing the sighting target handled by color difference, and two eyes
Finding sighting target neighbour can compare clarity, and when finding out, sighting target clarity seen in sighting target seen in amblyopia eye and Second eye is immediate
When sighting target, then the eyesight equalization point of eyes is found out.
Detailed description of the invention:
The black and white color difference visual chart schematic diagram that Fig. 1 present invention designs；
Fig. 2 is the binocular vision balance detection card that the present invention designs.
Advantage and effect: chromatism method is tested eyesight, and is the important supplement tested eyesight to national standard (GB 11533-1989),
By this check, can more one people of objective assessment eyesight.By can use big to such accumulation for checking data
Data analysis, more objectively diagnoses certain ophthalmology diseases.Binocular vision balance detection card can quickly check that amblyopia patient's is double
Eye vision equilibrium condition directly provides related correction parameter for amblyopia correction.
Specific embodiment:
Technical idea of the invention is: " the visual chart background color value " of the every row sighting target of Scientific Establishment, " visual chart background
Color value progressive increase rate ", " sighting target value of chromatism ", " sighting target value of chromatism lapse rate ", according to the visual chart that these technical parameters are designed,
It is objective, scientifically reflect eyes to the law of perception of color change.Meanwhile segmenting out black and white, black yellow, dark red, black green, black indigo plant
Five kinds of visual charts tested eyesight can check the sensing results of light source variation of the people to different wave length, thus more comprehensively
The objectively eyesight of one people of reaction, can more accurately determine certain ophthalmology diseases by big data analysis.
Using visual stereoscopic technology, the designing technique of binocular vision balance detection card is designed.
