Background technology

Since Gordon Gaile G once published an article in 1996 " Automated Glass Fragmentation Analysis ", the detection algorithm of glass fragment is 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 algorithms: 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. Haywood, J. W. V. Miller et al. develops a glass fragment automatic recognition system, and published an article " Automated Counting System in 1998 For the ECE Fragmagmentation 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 scan image, 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 in theory, due to the transparency of glass, up to the present, directly unsatisfactory by image digitization precision obtained by shooting, often must rely on artificial counting as supplementing.

In the glass applications of the special dimensions such as automobile, one is designed perfect cubing is to determine the stay-in-grade important factor of a glass product.Diversity due to present Automobile Design, glass on corresponding car is the most increasingly sophisticated, square or rectangle it is frequently not in glass profile, present parallelogram or trapezoidal glass can be found everywhere, in the past for the detection of this kind of irregular quadrilateral glass, there is no unified fixed frame, glass periphery can only be retrained by adhesive tape or other modes, or on safety glass, cover thin film, to prevent glass fragment from splashing.Adhesive tape also has and is burst, by safety glass, the possibility that strength collapses out simultaneously, causes operating personnel injured, and therefore, the improvement to safety glass fragmentation test frame is the most necessary.
