Part it is light tight, the loophole is respectively along two settings substantially symmetrical about its central axis；The controller falls within imaging for identification
Whether the image on paper is symmetrical.
Further, the loophole is circular hole.
Further, the loophole on light barrier cross centre line is circular hole, remaining loophole is semicircle orifice and three
The combination bore of corner apertures, the string of the semicircle orifice and the base of delthyrium overlap, and the setting of combination bore enables to carry out cylindricizing
Compared with when more easily determine.
Further, the light source is source of parallel light.
Further, eyeglass to be measured is placed in on sensitive paper, and the light source to light barrier distance and light barrier to be measured
The ratio of distances constant of eyeglass is 2:1.
Further, the light barrier into sensitive paper upper surface with drawing photoluminescence line cruciferous and light source side is set
Ultraviolet lamp is equipped with, the calibration for light barrier.
A kind of image-recognizing method of above-mentioned lens defects detecting system, controller is first by left and right two parts edge of image
Central shaft converts into, and judges whether left and right two parts are completely superposed；Two parts up and down of image are converted into along central shaft again, in judgement
Whether lower two parts are completely superposed；If can be completely superposed twice, judge into that image on sensitive paper is full symmetric, eyeglass is flawless
Defect；If wherein cannot once be completely superposed, the image non complete symmetry, the eyeglass that judge on sensitive paper have flaw.
The beneficial effects of the present invention are：By one-time detection operation can to including apparent flaws, internal flaw and
Multiple indexs such as optical property is bad are tested, efficient；And the present invention passes through light and shadow imaging technology and image recognition technology
Combination so that the price of system in itself is low, accuracy is high.
