Description
Technical field
The utility model relates to Machine Vision Detection field, is specifically related to a kind of mold code imaging device for code recognition system.
Background technology
The production run of various bottles (beverage bottle, bottle etc., especially beer bottle) need to be carried out strict quality testing, as checked, whether its bottleneck has whether recoverable etc. of crackle, bottle.Also need to review exactly simultaneously and cause reason off quality.If mould self defectiveness, that will cause the bottle disqualification rate of producing taking it as model to increase.The mould number that identifies defective mould has also just become the key factor of quality management.
Bottle, especially vial often indicate authentic language or symbol within the scope of above 20mm at the bottom of bottle, and being wherein used for identifying the numeric character that this bottle by which mould produced is mould (tool) number.Mould point is and pattern number salient point sequence one to one.Existing mould for glass bottle character identification system all adopts CCD to gather image, wherein adopts area array CCD scheme can under the rotating speed of 2 revolutions per seconds, complete dynamic acquisition image.After image acquisition completes, the character of utilization based on active contour model extracts identification character.
China has introduced many beer bottle production lines and has been enclosed within X-ray inspection X machine more from states such as the U.S., Belgium, France, for substandard product is rejected out from production line.The testing process of these online checking machines is basic identical.Beer bottle enters bottle checker one by one by travelling belt, after operator's console detects, is exported by travelling belt classification again.In the process of round turntable rotation, the vial coded image after the angle of the 360/N taking by N camera station changes, then the entire image of encoding by software synthetic mould is identified.Figure classification number in (list of references " research of the online pattern number recognition system of beer bottle " article numbering 1671-4598(2008) 09-1322-03: TH873.7 Document code A)
In prior art, there is the automatic recognition system of mould numbering, for example, at application number: 200920226221.5 utility model patent just provides a kind of " automatic recognition system of point mold code of glass bottle/jar ", but this patent is to carry out the identification of mould numbering with laser sensor and single-chip microcomputer.When laser process point-like mould, light intensity changes, thereby identifies mould number according to sensor make-and-break signal.In the time of practical operation, easily occur that a code-point makes mistakes, cause the whole mould situation that number identification makes mistakes.
Another kind of recognition system is provided in patented claim 201210148078, but in this patent in the time of practical operation, stability requirement for platform is higher, and the reading speed of number depends on the velocity of rotation of rotary table to a great extent, causes detection efficiency low; And owing to taking same mould region overall picture and need to carry out the image acquisition of multiframe, the image after collection extracts salient point information after need to re-starting amalgamation, heavier to the burden of system.
From present case, the mode of laser+sensor that existing bottle mould recognition system or use degree of accuracy are low is identified, or using a camera to take multiple image recognition coding region, identification quantity all depends on vial rotation rotating speed, and system stability is had relatively high expectations; Maybe need to coordinate multiple cameras to gather, increased input cost and the maintenance cost in early stage; After collection, need to carry out independent amalgamation processing, efficiency increases considerably slowly and because bottle rotating speed inequality causes the probability of mistake identification and None-identified.

Image-forming principle:
Because common imaging lens (especially wide-angle lens) itself has the perspective distortion of near big and far smaller (the distance here refers to the distance between lens and testee), in the time using common lens to observe bottom structure, the enlargement ratio at the bottle end is greater than the enlargement ratio with respect to the bottle side of camera lens farther place,, the enlargement ratio at the bottle end is greater than the enlargement ratio of sidepiece coding.Thereby make bottle bottom point seem larger, the side of bottle seems less so that cannot observe.
So inventor of the present utility model has introduced compound lens between the camera lens of camera and the bottle end that is taken, at the bottom of making bottle, be arranged in one times of focal length from the distance of compound lens, thereby first become the virtual image of an amplification bottle end being taken.Because the perspective distortion of the virtual image itself is near little long-range, seem that like this bottle side of outer ring is just more clear, and this perspective distortion is apart from less, distort larger.Therefore, inventor of the present utility model is arranged in 70mm with the distance of compound lens at the bottom of by bottle, to obtain enough large perspective distortion.But, in light path design, except at the bottom of bottle and the distance of compound lens, also need to consider the size of compound lens.The diameter of the lens before camera lens must be enough greatly could scioptics be observed the virtual image, the especially virtual image of sidepiece coding of this bottle.But along with the increase of lens diameter, the focal length of lens, by corresponding increase, only adopts single lens to be difficult to meet little focal length, large-sized requirement.So the utility model adopts compound lens to come forming the virtual image with perspective distortion at the bottom of bottle.The design of compound lens need to meet the double standards of lens diameter and the focal length of lens.
Mold code imaging device of the present utility model is refracted to positive area by the coding region of original bottle side that is not easy to observe and amplifies demonstration and detect by camera, and detection accuracy is high, and false drop rate is low.The utility model utilizes the perspective distortion of compound lens, the enlargement ratio of coding region is greater than bottle at the bottom of the enlargement ratio in centre, more easily coding is identified.
Mold code imaging device of the present utility model only just can carry out 360 degree detections to side, vial bottom coding region based on a camera, and do not need vial to be rotated, testing cost is low, and detection speed is fast, and can realize the measurement to vial physical dimension.The utility model, by see-through window is embedded in support platform, throws light on by the area source of top, makes whole testing process more smooth, need to be in the transport process of bottle, and carry out operation bidirectional and can realize bottle detection.
