At stable, no hot spot, do not cause under the light field condition of flicker, the imageing sensor collection is by detecting every bag cigarette of mouth, carry out Digital Image Processing by intelligent detector MCU according to set parameter and algorithm, output logic result (whether the current parcel that passes through is the difference bag).If be the difference bag, then when this parcel passed through sorting device, MCU sent control signal, by air valve parcel is rejected.
Every width of cloth gray level image is carried out pre-service such as denoising, edge enhancing and raising contrast, when differentiating, adopt " weight method ".
In the general industrial Flame Image Process, adopt pattern matching algorithm.If adopt pattern matching algorithm, image f promptly more to be checked
1(x is y) with standard picture f
0(operand is very big for x, y) similarity, for reaching the purpose of accurate identification, then the operational performance of image processor is had relatively high expectations, and this must increase the hardware cost of graphics processing unit.
Beat the feature of sign indicating number in view of cigarette parcel laser, in line with economical and practical principle, adopt in the Flame Image Process detection algorithm of this device " weight method ", promptly in cigarette parcel laser is beaten the zone of sign indicating number, by binary conversion treatment, calculate total pixel value X that laser is beaten yard image, if X＜Y, wherein Y is a setting value, then can judge this laser and beat a yard image and do not exist or be offset.If can judging cigarette parcel laser when total pixel is lower than setting value, to beat a yard disappearance, skew and character imperfect.During actual online detections, because light source design is appropriate, the image pretreating effect is obvious, and laser is beaten total pixel value of sign indicating number about 10000 pixels, and deviation is no more than 600 pixels, and total pixel value that laser is beaten yard is more stable.This just lays a good foundation for the identification judgement.
Advantage of the present utility model is to adopt the gray scale imaging, by light source is designed cleverly, and appropriate image pre-service and in image recognition, adopt particular algorithm, computing is simple.Under the less demanding prerequisite of hardware performance, finish high-speed motion cigarette parcel laser is played yard an online in real time detection and a rejecting.This Vision Builder for Automated Inspection can store the cigarette parcel laser that can remember 16 kinds of different trades mark and beat a yard image, can beat yard image according to the laser of different brand of cigarette and do different settings, has further guaranteed the quality of tobacco bale outward appearance.This Vision Builder for Automated Inspection can store the cigarette parcel laser that can remember 16 kinds of different trades mark and beat a yard image, can beat yard image according to the laser of different brand of cigarette and do
