Description
Technical field
The utility model belongs to textile detection technique field, is a kind of pck count automatic analyzer specifically.
Background technology
The density of fabric is meant the radical of yarn in fabric warp-wise or the broadwise fragment length; International standard ISO7211/2-1984 " mensuration of textile-woven fabric-structure analysis method-unit length yarn radical " and GB GB/T4668-1995 " mensuration of threads per unit length " have stipulated that the minimal segment length of manual measurement Density is 2cm; What measured generally speaking is the 5cm fragment, converts yarn radical to 10cm length as measurement index with the mean value at 5cm place.
The portable Density mirror that the common employing of the measurement of pck count at present is made up of scale and the magnifier that can on scale, move is measured by the artificial visually examine.Because color, the institutional framework of fabric are of a great variety, artificial visually examine's collimation error is big, and especially to twills, high tight ness rating fabric, irregular tissue fabric, velour, the artificial visually examine is difficulty very, and measuring error is especially big.
Summary of the invention
The problems referred to above that the utility model exists to prior art; A kind of pck count automatic analyzer is provided; Can detect the thread count of shades of colour, various institutional framework fabrics in general automatically, be easy to automatic assembly average, the coefficient of variation and relative error, convenient measurement, quick; Error is little, and precision is high.
The purpose of the utility model realizes through following technical scheme:
A kind of pck count automatic analyzer; Comprise fabric imaging and image identification system; It is characterized in that described fabric imaging and image identification system comprise casing, work top, optical microscope, CCD camera, sample holder, source of parallel light, the computing machine with image processing software, image pick-up card; Said sample holder is placed on the work top of casing; In the casing under the work top source of parallel light is installed, optical microscope is installed directly over the work top, the viewing window of optical microscope is connected with the camera lens of CCD camera; The digital picture output terminal of CCD camera is connected to image pick-up card through signal wire, and image pick-up card is connected with computing machine.
Improvement to technique scheme: the top of said casing connects a housing through a vertical support plate, and said CCD camera is installed in the housing, and the camera lens of CCD camera stretches out downwards from the housing bottom surface.
Further improvement to technique scheme: described source of parallel light is made up of light source and frosted glass, and frosted glass is between light source and sample.
Further improvement to technique scheme: described image pick-up card is installed on the mainboard of computing machine.
Further improvement to technique scheme: on the housing bottom surface of described optical microscope both sides a projection source is installed respectively.
The advantage and the good effect of the utility model are:
The image that CCD camera in the utility model is taken via optical microscope approaches desirable textile image, and image recognition algorithm utilizes the gap of yarn in the fabric can calculate the thread count of fabric easily as characteristics of image.The pck count automatic analyzer is fit to the quick measurement of fabrics in general, and especially it limit by fabric color, pattern, convenient measurement, reliably, fast, error is little, degree of accuracy is high.The utility model is a kind of automatic measurer that can verify with human eye.
Description of drawings
Fig. 1 is the fabric imaging of the utility model pck count automatic analyzer and the three-dimensional structure diagram of image identification system.
Embodiment
Referring to Fig. 1; The embodiment of a kind of pck count automatic analyzer of the utility model, its fabric imaging and image identification system mainly are made up of casing 1, work top 2, optical microscope 3, guidance panel 5, CCD camera 6, sample holder 8, source of parallel light, the computing machine 12 with image processing software, image pick-up card 13, display 14.The top of casing 1 connects a housing through a vertical support plate, and housing front setting operation panel 5 is installed said CCD camera 6 in housing, and the camera lens of CCD camera 6 stretches out downwards from the housing bottom surface.Optical microscope 3 is set directly over the work top 2, and the viewing window of optical microphotograph 3 is connected with the camera lens of CCD camera 6.
Tested sample 7 is installed on the sample holder 8; Sample holder 8 is placed on the work top 2 of casing 1; In the casing 1 under the work top 2 source of parallel light is installed; The digital picture output terminal of CCD camera 6 is connected to image pick-up card 13 through signal wire 11, and image pick-up card 13 is connected with computing machine, and image pick-up card 13 can be directly installed on the mainboard of computing machine 12.
Described source of parallel light is made up of light source 9 and frosted glass 10, and frosted glass 10 is between light source 9 and sample 7.In order to make the image that obtains more clear, the both sides that the housing bottom surface above casing 1 is positioned at optical microscope 3 respectively are equipped with a projection source 4.
The axial mechanics stretching of the also configurable a pair of of the utility model apparatus for correcting; Twin shaft is used for fabric is implemented the mechanics drawing process of a underload to mechanics stretching apparatus for correcting; Thereby correct the diagonal distortion of sample, by force draw back fabric structure, make to draw close between yarn together and form the effective clearance, so that generate the characteristic that helps image detection.
The course of work of pck count automatic analyzer:
Be clamped in sample 7 in the sample holder 8 of two pairs of flat chucks compositions, apply an initial pretension and make sample 7 keep it smooth, sample holder 8 is placed on the work top 2.Switch on the opening operation panel 5; Being positioned at light source 9 under the sample 7 becomes approximate directional light through frosted glass 10 and is backprojected on the sample 7; Start CCD camera 6 and obtain textile image, observe image aspects, need to determine whether to stretch through video; Like needs, sample holder 8 is put into twin shaft after stretching on the mechanics stretching apparatus for correcting, obtains image again.
