It should be noted that described stravismus intelligence Inspection and analysis system also includes muscular strength mutation analysis module, for rightThe eye position static image data carrying out calibrating through image scaling calibration module carries out muscular strength change-detection.With specific reference to interpupillary distance andThe high change when different fixating eye position of pupil is analyzed the hyperfunction of which bar or which eye muscle power or weakens.

It should be noted that described stravismus intelligent detection and analysis system includes thumbnail frame generation module, for pin respectively10 of two eyes are watched attentively orientation one thumbnail frame of generation and show on display module, display correspondence in thumbnail frameEye position still image thumbnail.

The method utilizing above-mentioned stravismus intelligence Inspection and analysis system to carry out strabismus checking is:

S1 measurement standard interpupillary distance, i.e. watches eye pupil heart distance * 2 to bridge of the nose center line attentively.Eyes are can not be when having stravismus simultaneouslyWatch same target attentively, now have an eye gaze target, can not watch attentively for other one.These eyes that can watch attentively are just namedFixating eye.

S2 patient wears zoom mark-up frame, and camera module obtains eye position dynamic image data and shows at display moduleOn；

S3 examiner watches the eye position dynamic image data on display module, adjusts the head position of patient so that it is pupil heart lineClose to horizontal line.When having horizontal reference line generation module, then using horizontal reference line as reference；

S4 patient with fixating eye to 10 orientation (the timely 33cm of front 5m, to the left, to the right, upwards, downwards, to upper left toLower-left, to upper right, to bottom right) watch attentively, and by instruction input module (such as mouse etc.) to control module input instruction, control mouldBlock controls still image acquisition module and obtains the eye position static image data under each orientation.

S5 patient with 10 orientation of another eye gaze (the timely 33cm of front 5m, to the left, to the right, upwards, downwards, toUpper left to left down, to upper right, to bottom right), and by instruction input module (such as mouse etc.) to control module input instruction, controlModule controls still image acquisition module and obtains this eye position static image data under each orientation.

In step S4 and S5, when having thumbnail frame generation module, behind one orientation of eye gaze of patient, permissibleClick on these eyes by instruction input module, watch the thumbnail frame corresponding to orientation attentively, it is achieved input obtains this position static mapControl instruction as data.In the thumbnail frame of the thumbnail display correspondence of the eye position static image data after acquisition.ThumbnailBy different border colors, frame can show that the acquisition situation of eye position static image data that this thumbnail frame is corresponding is (such as HuangFor not obtain during color frame, green frame is for carrying out obtaining operation, blue for obtaining).

S6 corrects the pupil heart line of the eye position static image data taken the photograph in step S4 and S5 and is located at same level line.Especially by the pupil heart of the right and left eyes in instruction input module click picture, then this view data makes automatically rotating to an angleThe pupil heart line obtaining two is a horizontal line, and one of them view data rotates, and other view data also can rotate the most in the lumpIdentical angle.

S7 clicks in the static image data of eye position and is positioned at the lower left corner of zoom mark-up frame and two calibration points in the lower right corner, thenThis position static image data is zoomed in and out by image calibration module automatically, until consistent with actual, measured dimension.To allEye position static image data all carry out identical operation.

S8 clicks on two eye pupils obtaining the eye position static image data through calibration in step S7 by instruction input moduleHeart position, interpupillary distance measurement module and pupil heart measurement module measure interpupillary distance and the pupil calculation evidence of this position static image data automatically,Measure the data obtained to be stored in data memory module.All of eye position static image data is all carried out identical operation；

When having muscular strength mutation analysis module, also can be to the eye position static map calibrated through image scaling calibration moduleAs data carry out muscular strength change-detection and store the result in data memory module.
