Description
Affiliated technical field
The utility model relates to a kind of automatic detection device of flour bran speck, especially a kind of being positioned on the flour production line, and perhaps flour mill's quality monitoring is indoor, is used for the real-time or fast automatic device of flour bran speck.
Background technology
Flour bran speck is meant visible in the final flour (with the naked eye can discern), and color is obviously deceived the spot in flour, its principal ingredient is the wheat bran of not separating in the wheat processing flour process, buckwheat skin, the grass-seed skin do not cleaned out are also arranged, even also have the black stone piece big or small, that proportion is close with wheat, cinder etc.The single size of flour bran speck and quantity what not only influence the purity and the whiteness of flour, also will influence other indexs of correlation of flour production process as: contain bran rate, flour grade etc. in flour extraction, the powder.Can weigh more in the flour production run whether cleaning clean, whether whether proper, screen coupling is adjusted in the flour mill collocation reasonable etc.Can draw also therefrom that the wheat flour milling Processes and apparatus is whether advanced, whether operation reasonable etc.Because the flour of China is edible to be based on boiling, the consumer also very take notice of the single size of flour bran speck and quantity what.How much content of bran star is an important indicator of flour quality ranking in the flour, also is the important indicator of reflection flour production technology level.
Though because the area of flour bran speck is little, quantity is many, and is fairly obvious in the flour of white, particularly high-visible especially in steaming good steamed bun, we are difficult to its accurate quantityization.It is high, normal, basic, many and few that we can only estimate the bran star (as a special powder, special two powder, standard flour) of which kind of flour, is what, hangs down what are all is difficult to its accurate quantitative expression as for height.Flour mill and flour inspection body in all parts of the country (have only flour bran speck with sense organ with choosing with sense organ expert's every year (or half a year) of national food check aspect, other parameters all have detail requirements such as national standard, the method for inspection, inspection machine) grade flour sample compare with the flour that will check, provide whether certain flour bran speck exceeds standard and decide this flour quality and grade, speed is slow, error is bigger.
" automatic detection device of flour bran speck " is based on the instrument that detects flour bran speck content in real time, fast and automatically of computer vision technique.The on-line monitoring that can be used for flour manufacturing enterprise makes it can monitor the flour condition of production in real time, also can be used to detect the bran star content of censorship flour sample as the detecting instrument of flour testing agency simultaneously.
The identification of bran star and measurement are based upon on Digital Image Processing and the pattern-recognition theory basis.Take the flour image in real time or fast with camera, the flour image converts digital pictures to through image pick-up card and sends into computing machine, goes out the size of each bran star in the ratio, flour of number, the shared flour of bran star of bran star in the flour etc. through flour bran speck identification and software for calculation system-computed.Flour bran speck identification mainly comprises the pre-service of flour image and the identification and the Measurement Algorithm of bran star with the implementation algorithm of software for calculation system.Be gray level image at first in the pre-service of image with the RGB true color flour bran speck image transitions of CCD camera collection, adopted the influence of medium filtering, gaussian filtering, morphologic filtering, Laplce's sharpening, rim detection scheduling algorithm then, finally adopted Gauss's smothing filtering to add the Processing Algorithm of Laplce's sharpening Flame Image Process.On pretreated basis, the bran star in the image is detected, adopt to comprise the whole bag of tricks such as sciagraphy, difference shadow method, template matching method, linear discriminant analysis, K mean cluster method.Use for reference the thinking of Threshold Segmentation and template matching method at last, utilize the bran star characteristics different with the flour gray-scale value, employing is divided into the method for a plurality of fritters with the flour image, and single fritter is calculated the optimal threshold that gray-scale value is tried to achieve image, the number of bran star and size in the computed image.On this basis,, finish bran astrology pass information and obtain work, on display device, show the data that obtain, finished the detection by quantitative work of bran star the analysis of image degree of comparing.
This system mainly detects the quality of flour from three aspects: the size of each bran star in the ratio of the number of bran star, the shared flour of bran star, the flour the flour.
Summary of the invention
The purpose of this utility model is the problem that will solve the bran star content in real-time or the fast quantification detection flour, whether the device of the size of each bran star in the ratio, flour of number, the shared flour of bran star of bran star in a kind of direct demonstration flour, it is normal etc. to allow flour mill grasp flour quality situation, production technology, equipment and operation at any time if being provided.Also can be used for simultaneously flour mill quality monitoring chamber or flour quality testing agency fast detecting flour bran speck content.
The utility model is to adopt following scheme to realize: take the flour image in real time or fast with camera, in order to make shooting flour image not influenced by other light, autogamy LED image acquisition illuminating lamp before the camera, (integrated circuit board meets the PC/104-PLUS standard to the flour image through the built-in image collection card, be of a size of the 90*96 millimeter) convert digital pictures to and send into 3.5 inches veneer industrial control computers, go out the size of each bran star in the ratio, flour of number, the shared flour of bran star of bran star in the flour etc. through flour bran speck identification and software for calculation system-computed.Flour bran speck identification mainly comprises the pre-service of flour image and the identification and the Measurement Algorithm of bran star with the implementation algorithm of software for calculation system.Be gray level image at first in the pre-service of image with the RGB true color flour bran speck image transitions of CCD camera collection, adopted the influence of medium filtering, gaussian filtering, morphologic filtering, Laplce's sharpening, rim detection scheduling algorithm then, finally adopted Gauss's smothing filtering to add the Processing Algorithm of Laplce's sharpening Flame Image Process.On pretreated basis, the bran star in the image is detected, adopt to comprise the whole bag of tricks such as sciagraphy, difference shadow method, template matching method, linear discriminant analysis, K mean cluster method.Use for reference the thinking of Threshold Segmentation and template matching method at last, utilize the bran star characteristics different with the flour gray-scale value, employing is divided into the method for a plurality of fritters with the flour image, and single fritter is calculated the optimal threshold that gray-scale value is tried to achieve image, the number of bran star and size in the computed image.On this basis, to the analysis of image degree of comparing, finish bran astrology pass information and obtain work, on LCDs, show the data that obtain, size as each bran star in the ratio of the number of bran star in the flour, the shared flour of bran star, the flour, finally finished the detection by quantitative work of bran star, simultaneously also can be by these data of printer output.Parameter setting and feature operation all realize on touch-screen.
