Description

A kind of plate wheel turntable screw rod shooting wheel Corner clamp glass detection device

Technical field

This utility model relates to a kind of safety glass test verification device, and the test verification device particularly relating to wear industrial camera substitutes manually-operated a kind of plate wheel turntable screw rod shooting wheel Corner clamp glass detection device.

Background technology

G0rd0n Gaile G once published an article in 1996 " Aut0mated Glass Fragmentati0n Analysis ", the detection algorithm of glass fragment to be inquired into, the document relates to two key technologies: (1) image capture technology.Below the sensitive paper of a glass fragment imaging, apply light source respectively from two different angles, respectively collect the original digital image of a width fragment slot line shadow.So, owing to employing the light source of different angles, the two width images the most difference collected.Wherein piece image produces the position of inconspicuous slot line due to illumination reason, the most obvious in other piece image.Therefore, in due course two width images being combined, the discontinuous phenomenon of slot line can be improved.(2) image segmentation algorithm.Cutting procedure includes the following steps: pretreatment is removed in two width original images by the reflective the brightest or the darkest noise caused of the dust in glass or slot line edge；Carrying out independent slot line detection, two width images are merged into the image of the complete slot line of a width, extract slot line, finally carry out fragment identification.J. Hayw00d, J. W. V. Miller et al. develops a glass fragment automatic recognition system, and published an article " Aut0mated C0unting System F0r the in 1998 ECE Fragmagmentati0n Test》.Its recognition methods can be described as: the debris field of to be counted piece of number is marked on sensitive paper artificially, and scanner scanning obtains digital picture.Subsequent treatment is carried out based on scanogram, and image processing step includes: compensate uneven illumination, reduces noise, determines slot line.Before statistics block number, employ a kind of special recovery algorithms and fill the slot line of " loss ".This system can identify and count the quantity of the fragment in tab area.
