Embodiment Construction

[0019] to combine figure 1 , figure 2 As shown, the digital microscope-based woven fabric density detector of the present invention includes a common stereo microscope, a CCD digital camera, a computer and supporting woven fabric density detection software.

[0020] The working principle of the present invention is as follows: the surface reflection image of the woven fabric is collected through a digital microscope, the fabric image is read in based on the USB or IEEE1394 interface, Fourier transform is performed on the fabric image, and the image is filtered in the frequency domain to obtain the warp and weft yarn separation. Group the yarn image, use the adaptive threshold method to locate the yarn, count the number of yarns within a certain length, and calculate the warp and weft yarn density of the woven fabric.

[0021] The hardware structure principle of the present invention is as figure 1 As shown, the interface of the woven fabric density detection software is as ...

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.

Description

technical field [0001] The invention relates to a woven fabric density detector developed with a digital microscope as the core, in particular to collecting woven fabric surface images with a digital microscope, and reading the woven fabric images into a computer through a USB or IEEE1394 interface. Use the Fourier transform method to convert the woven fabric image to the frequency domain, and use the frequency domain filter to decompose the woven fabric image into a single group of warp and weft yarn system images, and count the number of warp and weft yarns in the single group of warp and weft yarn images , combined with the image magnification, automatically measure the warp and weft yarn density of the woven fabric. Background technique [0002] In the process of woven fabric production, it is generally necessary to obtain the density parameters of the woven fabric according to the fabric sample for regeneration. In the traditional manual analysis method, the fabric den...
