Abstract
The utility model discloses a device adopting an optical image method for measuring cotton fiber impurities, which is provided with a testing window. Two routes of standard light sources are symmetrically arranged on two sides of the testing window, 45-degree angles are formed among the two routes of standard light sources and perpendicular lines of the testing window, and a lens mounted under the testing window is connected with a camera through an optical adjuster. The device solves the following technical problems: a) stability of the two routes of standard light sources, the design and realization of adjustable optical paths and illumination uniformity of the 90 mm * 90 mm testing window; b) the design of the optical adjuster and definition of impurity images of to-be-measured cotton fibers; c) impurity image processing models of cotton fiber impurity measuring softwares.
Description
Affiliated field
The utility model belongs to the inspection machine technical field, and particularly cotton fiber checking system, textile industry are measured the device of cotton fiber impurity.
Background technology
Examination of fibers department and textile industry are very paid close attention to the impurity performance of cotton fiber, for a long time, inspection department of China and textile enterprise adopt the weight method of mechanical type removing impurities to the impurity measurement of cotton fiber, the shortcoming of this method is the quick measurement requirement that measuring speed is very slow, can not satisfy the cotton quality check, and weight method can not effectively be measured the leaf bits impurity of cotton fiber in addition.
At present, it is more and more that the machine of China is adopted cotton quantity, and it is that leaf bits impurity content is many especially that machine is adopted cotton maximum characteristics.There are very big demand in inspection department and textile enterprise for the instrument of the leaf bits impurity of energy measurement cotton fiber.
Summary of the invention
The utility model purpose is the device that a kind of optical imagery method of design is measured cotton fiber impurity, with the needs of realizing that cotton quality detects.
The optical imagery method is measured the device of cotton fiber impurity, it has test window, two-way standard sources and two-way standard sources become miter angle with the test window perpendicular line direction is housed in that test window is monosymmetric, camera lens is housed under test window, and camera lens is connected with video camera by the optical adjustment device.
Light source adopt symmetry, same power, with the halogen tungsten lamp of colour temperature.From shining tested cotton fiber, guarantee that test window illumination has the good homogeneous degree with tested cotton fiber surface normal 45 degree direction both sides.
On the receiving light path of optical system, installed diaphragm.Help to reduce the optical system that extraneous parasitic light enters the test of cotton fiber color and luster.
The utility model has solved following technical barrier:
A) uniformity coefficient of the test window illumination of the design of the stability of two-way standard sources, adjustable light path and realization, 90mmX90mm.
B) the impurity image definition of the design of optical adjustment device, tested cotton fiber.
D) the impurity Flame Image Process model of cotton fiber impurity measurement software.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Having provided the utility model basic comprising as figure. the device that the optical imagery method is measured cotton fiber impurity mainly is made up of two-way standard sources, optical system (comprise and survey glass pane), camera lens, optical adjustment device, ccd video camera, image pick-up card, computing machine and special-purpose impurity image processing software etc.; Two-way standard sources 2 and two-way standard sources 2 become miter angle with test window 1 perpendicular line direction is housed in that test window 1 is monosymmetric, camera lens 3 is housed under test window 1, camera lens 3 is connected with video camera 5 by optical adjustment device 4. and light source adopts symmetrical, same power, halogen tungsten lamp with colour temperature, from shining tested cotton fiber with tested cotton fiber surface normal 45 degree direction both sides, guarantee that test window illumination has the good homogeneous degree. on the receiving light path of optical system, installed diaphragm, reducing the optical system that extraneous parasitic light enters the test of cotton fiber color and luster. optical system is selected the pin optical lens, special optical adjustment device, high-resolution industrial camera etc., image acquisition adopts high performance pci card. special cotton fiber impurity image processing software, by blank and impurity plate instrument is calibrated with standard, finish accurate measurement, and impurity carried out classification the impurity grain number and the impurity area relative percentage on tested cotton fiber surface.
Principle of work: the two-way standard A light source of symmetry, to become the direction of miter angle to shine on the surface of tested cotton fiber (test window is 90mmX90mm) with tested cotton fiber, received by camera lens on the direction that becomes an angle of 90 degrees with tested cotton fiber by diffusing of tested cotton fiber surface, by the optical adjustment device, CCD by video camera receives the image that the back forms tested cotton fiber, by image pick-up card the image of tested cotton fiber is gathered, and then the image of being tested is carried out analyzing and processing by cotton fiber impurity measurement software, draw the impurity grain number of tested cotton fiber, the impurity area, impurity levels.
Measuring process: before the impurity measurement, must calibrate instrument with standard white plate and standard impurity plate.During impurity measurement, start Survey Software, an amount of cotton fiber is put into the impurity test window, the started by press switch, after the impurity image of tested cotton fiber passes through camera lens, optical adjustment device, ccd video camera, gather by image pick-up card, at last the impurity image of tested cotton fiber is carried out analyzing and processing, draw the impurity performance index of cotton fiber by special process software.
