Notice, guiding user see to camera lens, accurate acquisition image.Two distance of camera lens are 6cm, according to the interpupillary distance between human eye
Design.
It is illustrated in figure 5 equipment and uses flow chart, is under preview state, can be carried by ultrasonic ranging in optometry unit
Show measured's distance and on the touchscreen display distance, position of human eye is recognized by visible light lens, when human eye and lens distance
Regulation to touch-screen during 100cm has captions to point out and auditory tone cues；Then, integrated manipulator control lighting source and photographing element
Synchronous flashing light and take pictures, complete to gather eye image, automatic optometry is finally completed by calculating, and display is tested on the touchscreen
Light result；In whole process, central processing unit realizes the process of whole automatic optometry by test position and apart from adjustment；
Whole process is automatically performed and data display is stored in the information centre of tested person, and the process coordinates without other people.
It is illustrated in figure 6 optometry unit and uses eyes in algorithm the distance between to camera lens, Computing Principle：We set
The fixed range 100cm of human eye to image pickup plane is calculated.It will be appreciated from fig. 6 that eyes plane to camera lens plane apart from L '2
=L2+(D/2)2.Wherein L ' is distance of the eyes plane to camera lens plane, and L is that ultrasonic wave mounting plane is put down to face
The measurement distance in face；D is the interpupillary distance of eyes.Many at present calculate all is to remove eyes pupil spacing, and such words application condition is big.
According to the people and camera lens detected apart from L '：We set human eye to the fixed range 100cm of image pickup plane, if
Standby to measure the distance between face plane and lens plane according to ultrasonic ranging, twin-lens can carry out 3D weights to face part
Build, human eye plane is one three-dimensional to people's forehead plane, two dimensional image has error, and rebuilds and can more accurately measure by 3D
Spacing between eye plane and camera lens, improves measurement accuracy.And pass through our forward/backwards of sound or word, light prompt
It is mobile, for attracting babies and children's eyes are protected, we are using the more gorgeous rotating light rotation of the colors such as RGB color
Turn to show and coordinate soft music.
Color is the important information in computer vision, is commonly used in the fields such as extraordinary extraction, target identification, motion tracking
Arrive, but in real scene, light source is not preferable, and the color of light source and brightness and the change of environment can all make target
Color is changed in the picture.After present invention shooting for the picture of the image spot of human eye formation, light is mainly to look for
The edge of spot and the influence for removing pupil.We first intercept to picture in practical operation, intercept the eye of suitable dimension
Negative film, carries out basic filtering process, then using color compensating technology, and the oculopupillary face of people is recognized according to visible light lens
Color is compensated to the image of black and white picture, takes edge detection algorithm filtering method to carry out border searching, then according to minimum
The bright dark border of square law mode approach and pupil boundary.
Preview interface prompting is illustrated in figure 7, ultrasonic ranging measurement people's forehead plane arrives the distance between camera lens, passed through
3D Modifying model human eye planes arrive the distance between camera lens, point out us left/right to move according to interocular distance, to reach people
The eye plane position parallel with camera lens.The optometry unit only needs to be pointed out according to the image comparison collected according under preview mode
We move forward/backward/left/right.The equipment in use, for position of human eye identification be very easy to, regulation
