The utility model also includes cigarette appearance images detection method, comprises the following steps：
1st, the standard picture of qualified cigarette is stored：Using first turn around wheel probe 12, second turn around wheel probe 22
The standard picture of qualified cigarette outward appearance is obtained with detection wheel probe 32 and is stored；
2nd, image is obtained：Using first turn around wheel probe 12, second turn around wheel probe 22 and detection wheel probe 32 obtain cigarettes
The realtime graphic of branch outward appearance；
3rd, by the realtime graphic that step 2 obtains compared with the parameter of the standard picture of step 1；
4th, when the tolerance of realtime graphic in step 3 and the parameter of standard picture is in the setting margin of tolerance, then it represents that this cigarette
The outward appearance of branch is qualified；Otherwise, it is as unqualified.
Specifically, cigarette appearance images detection method is mainly made up of following steps：
(1), image obtains:Under stable, uniform lighting environment, cigarette to be measured is obtained by single or multiple cameras
Image, and the image collected is sent to computer；
(2), image procossing:Image processing algorithm is utilized in a computer, and image is carried out to the cigarette image to be measured of acquisition
Early stage is handled, and needs to use many algorithms among these, as follows：
First, the filtering of image
In cigarette digitized image acquisition process, due to the inhomogeneities of CCD sensitivity in opto-electronic conversion, digitized
The influence of the factor such as the quantizing noise of journey and the channel errors of transmitting procedure, it may include in the image that video camera obtains each
Kind random noise.In order to improve the analysis of vision system and recognition capability, it is necessary to remove the noise in original image.
Smooth and clear inherently contradiction.In medium filtering, the effect of cross windowing is better than diamond-shaped windows, water chestnut
The effect of shape window is better than rectangular window, and the effect of 3 × 3 small windows of area is better than 5 × 5 windows, at 3 × 3 window
The pixel of reason is fewer than 5 × 5 window, that is, makes the more efficient of 3 × 3 windows.The smoothness of 5 × 5 windows is more preferable, figure
Noise as in, which is compared, to be much smaller, but its counter productive is bigger, and image becomes very fuzzy.In summary, in the project
With 3 × 3 cross window.
2nd, the enhancing of image
Cigarette image is pre-processed using histogram enhancement technology, system obtains original image and its intensity histogram
Figure, analysis histogram distribution know original image histogram distribution scope relative narrowness.Nogata is obtained to histogram equalization processing
Scheme enhanced image and its histogram, picture contrast significantly improves, and this is very favorable to pictures subsequent analysis.
3rd, the registration of image
Cigarette on a production line, its image has offset and rotation unavoidably, so to corresponding coordinate on respective image
Calculating just has deviation, and its result often judges program by accident, so must be corrected for the image of collection.Adopted in this software
With coefficient correlation method, template image is moved into continuous calculating coefficient correlation on image to be corrected, is worth maximum a bit
It is exactly matching a little for template.The coordinate value of the point subtracts the coordinate of template in standard picture, has just obtained the inclined of image to be corrected
Shifting value.But because the amount of calculation of this method is very huge, its efficiency is low, it is difficult to meet the requirement in industry automatic control.
So this software employs hierarchical search technology and substantially reduces search time, the efficiency of program execution is improved.In this software
Five layers are divided.Template is scanned on the image in respective layer with correlation coefficient process, using coefficient correlation highest some as
Candidate point, and in the higher leveled layer of resolution ratio, only several candidate points are calculated, then it is several with being selected according to the value of coefficient correlation
Individual candidate point, is calculated in artwork successively, using correlation coefficient value highest a little as matching a little.
4th, the rotation correction of image
Small angle also be present in addition to it the skew on horizontal level (skew i.e. on coordinate) be present in cigarette on a production line
The rotation of degree.In order to overcome the identification mistake caused by image rotation, image processing system must carry out school to cigarette image first
Just, method is that the datum mark of image rotation recovery is found using template matches, carries out image rectification.This software is inserted using bilinearity
Value method is corrected to image.
5th, the texture analysis of image
Sampled images are analyzed using the knowledge and algorithm of texture analysis, if cigarette has fold, pass through hardware
Special polishing, will cause it is strong reflective, be reflected in cigarette image be exactly large area strong white region, therefore, detection is calculated
Method must be able to the pixel variations in detection zone, and this software is using the method for calculating image energy.But due to the chi of sampled images
Very little is 648 × 492, and so big region entirety is calculated, will be taken a long time, it is impossible to meet the timely of industry spot
Property require.Setting rectangle is calculated so this software uses, multiple rectangles are set in the sensitizing range of image, so, section
About the time, meet the requirement of live promptness.
6th, the gray-scale statistical of image
The picture on surface of many cigarettes is complicated, and its surface is made up of relatively regular texture, without flat region, in utilization
The method in face can not obtain good effect, it is proposed that the method for gray-scale statistical, judge image according to the characteristic of histogram
Quality.This method can act on any type of pattern, also allow for this method and apply than wide.Using when, by Nogata
Figure instrument is placed on image, and adjusts size according to region to be measured.
(3), graphical analysis and identification:The plane outspread drawing of the entirety cigarette to be measured obtained to step (2), in a computer
By artificial intelligence and mode identification technology, color, texture, shape information and the foundation for analyzing cigarette surface region to be measured are known
Other model, and automatic discrimination defect type and parameter index, finally identify the appearance quality of cigarette to be measured.
Cleaning Principle：Cigarette presentation quality on-line measuring device carries out image recognition to the position that cigarette is detected.First
Qualified cigarette standard picture is stored.The image of detection cigarette, and being compared with the image of storage in real time in production process
Compared with.If histogram, similarity (FIT), image position coordinates (X, Y) etc. represent this cigarette outward appearance within the tolerance of setting
It is qualified, otherwise it is that outward appearance is unqualified.Software uses full Chinese interface, and friendly interface is simple to operate.
Cigarette presentation quality on-line measuring device of the present utility model is simple in construction, reasonable in design, in turning around for cigarette machine
Two sets of wheel probes that turn around are set at wheel, detect the half periphery Appearance quality defect of turn around cigarette and the non-cigarette that turns around respectively,
A set of detection wheel probe is set at detection wheel, detects second half periphery Appearance quality defect of cigarette at detection wheel.
