Abstract
The invention discloses a woven fabric count detector based on a digital microscope, belonging to the field of novel spinning detection instruments. Fabric count refers to the quantities of warp and weft yarns within a unit length of a fabric. The conventional manpower-dependent detection method has the defects of time and labor wasting and high subjectivity, and cannot meet the requirement of spinning production automation obviously. Specific to the technical problem, the digital microscope is taken as image acquisition hardware, and automatic detection of fiber count is realized in combination with an image processing method, so that an automatic woven fabric count detection instrument is realized. A CCD (Charge Coupled Device) digital camera is used for acquiring a fiber surface image amplified by a microscope objective, and a fiber image is read into a computer through a USB (Universal Serial Bus) or an IEEE1394 interface. The obtained fiber image is subjected to Fourier transform, and separation of warp yarns from weft yarns in the fiber image is realized with a frequency domain filtering method. The quantities of warp and weft yarns within certain lengths are counted in a separated single group yarn image, so that the woven fabric count is computed automatically.

In computing machine, utilize Borland C++Bulider 6.0 to make up threads per unit length and detect software, at first read the woven face image that digit microscope collects, and make up textile image real-time processing platform by the data communication mouth.In the testing process of threads per unit length, at first the woven fabric image is made Fourier transform, image is transformed into frequency domain from time domain; Then the fabric frequency domain figure is looked like to carry out frequency filtering, realize the separation of filling yarn system in the textile image, obtain through weft yarn list group figure warp thread picture; In weft yarn list group figure warp thread picture, image is made adaptive threshold handle, the location filling yarn; Add up the filling yarn radical in the certain-length at last, calculate woven fabric filling yarn density.The function implementation procedure of the threads per unit length automatic tester of invention as shown in Figure 2.
The threads per unit length automatic tester of realizing by the present invention, automatic detection that can threads per unit length is for the automatic analysis of woven fabric structure parameter lays the foundation.
Summary of the invention
The purpose of this invention is to provide design of hardware and software principle and implementation method that a kind of threads per unit length detects automatically, utilize the realtime graphic treatment technology to realize the full-automatic detection of woven fabric through weft count, thereby replace existing threads per unit length detection method, improve the accuracy that Density detects, liberate the productive forces simultaneously, adapt with the modern textile automated production.
The technical solution used in the present invention is as follows:
(1) a kind of woven fabric image-pickup method based on digit microscope, comprise common stereomicroscope (requiring object lens magnification) more than 10 times, CCD digital camera (resolution that requires camera is more than 2,000,000 pixels), USB or IEEE1394 data line and data-interface, reflection and transmitted light source;
(2) a kind of woven fabric image real time processing system, comprise and utilize Borland C++Bulider 6.0 to make up woven fabric image real time processing system interface, read in the image that digit microscope is gathered by USB or IEEE1394 interface, and the real-time implementation method of handling of textile image;
(3) filling yarn separation method in a kind of woven fabric image comprises and utilizes Fourier transformation method that textile image is transformed into the frequency domain scope, in frequency domain fabric is made Filtering Processing, obtains the single group figure warp thread picture that separates through weft yarn;
(4) a kind of threads per unit length method for automatic measurement comprises that single group figure warp thread that the pair warp and weft yarn separates looks like to do the adaptive threshold processing, the location filling yarn, and the filling yarn radical in the statistics certain-length calculates filling yarn density.
The present invention utilizes digit microscope to realize the automatic measurement of threads per unit length, offers help for the automatic analysis that further realizes the woven fabric structure parameter, and the while also provides a kind of exemplary platform for the automatic analysis of textile images.
