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
Coefficient correlation method is used, template image is moved into continuous calculating coefficient correlation on image to be corrected, is worth a bit maximum
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 being calculated, then select with the value according to coefficient correlation several
Individual candidate point, is calculated in artwork successively, using correlation coefficient value highest a little as matching a little.

Sampled images are analyzed using the knowledge and algorithm of texture analysis, if cigarette has fold, pass through hardware
Special polishing, will cause 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 is used, 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, using upper
The method in face can not obtain good effect, it is proposed that the method for gray-scale statistical, and image is judged according to histogrammic characteristic
Quality.This method can act on any type of pattern, also allow for this method and apply than wide.Using when, by Nogata
