Embodiment
The present invention provides it is a kind of be used for transparent/translucent product in foreign matter detection device, for make the purpose of the present invention,
Technical solution and effect are clearer, clear and definite, and the present invention is described in more detail below.It is it should be appreciated that described herein
Specific embodiment only to explain the present invention, is not intended to limit the present invention.
First, from principle, according to the basic principle of polarization optics, after material and light action, the polarization state of light
It can change, the polarization characteristic of different material is different, and the polarization characteristic of same substance is also related with many factors, including incidence
Wavelength, incident angle and detection angle of light etc., Muller matrix (Muller Matrix) can be described comprehensively in certain bar
The polarization characteristic of some target, is defined as follows under part：
Muller matrix is a quadravalence Real Square Matrix, can with the two-way decay of expression thing confrontation incident light, bit phase delay and
It is polarized the effects such as depolarization.By carrying out different decomposition to Muller matrix, the multi-aspect information of target can be obtained, is visited in target
There is important application in the fields such as survey, biomedicine.
In target detection and identification field, transmission, the circular component of reflected light are smaller, and Muller matrix deteriorates to three at this time
Rank square formation, i.e.,：
Transparency liquid foreign bodies detection belongs to field of target recognition, it is assumed that the Stokes vector of the irradiation level of lighting source is
DE, the polarization transfer matrix of transparent vessel is M1, and the polarization transfer matrix of liquid is M2, and the polarization transfer matrix of foreign matter is M3,
Transmit, reflect after liquid and foreign matter, the Stokes vector of scattering light spoke brightness be dL1, transmission during foreign, reflect,
The Stokes vector for scattering light spoke brightness is dL2, and simplified model is as shown in Figure 1.
As shown in Figure 1, the polarization spectrum characteristic of emergent light is after the light beam that light source is sent and container, liquid, foreign matter act on：
dL1=M1·M2·M1·dE (3)
dL2=M1·M2·M3·M2·M1·dE (4)
From formula (3), formula (4), after foreign matter, its polarization spectrum characteristic will change incident light, at least through
Following two means can realize the detection of foreign matter：
First, under same light source lighting condition, according to the polarization characteristic of emergent light, realize foreign bodies detection.Illuminating bundle
Its polarization characteristic will change after foreign matter, and product significantly polarizes gradient on the interface of foreign matter and liquid, and setting is closed
Suitable Grads threshold can realize the detection of foreign matter, and traditional strength investigation is had to the sensitivity of higher.
Second, under specific polarized light source illumination, according to the polarization characteristic of emergent light, the polarization transfer matrix of inverting foreign matter
(i.e. Muller matrix), by carrying out different decomposition to Muller matrix, obtains the build-in attributes such as material, the shape of foreign matter, and then
Realize the detection of foreign matter.
Secondly, from technical operation, the foreign matter detection system based on short-wave infrared polarization spectrum characteristic includes three-dimensional illumination
System, image capturing system, data handling system, target identification system four are most of, as shown in Figure 2.
Lighting system produces a wavelength, short-wave infrared incident light irradiating sample known to polarization state, by multi-angle, more
Orientation Lighting Design, ensures the effective lighting of transparent bottle wall, bottom of bottle to be measured；Image capturing system is by more direction optimization designs
Indium GaAs polarization camera composition, the camera of diverse location correspond to specific type of lighting, ensure foreign matter polarization spectrum characteristic
Optimum sensitivity；Data handling system is merged the polarization image data of polyphaser, multichannel, and it is multispectral to complete foreign matter
The parsing of polarization characteristic；Target identification system is automatically performed the knowledge of foreign matter according to type, state and the auxiliary data of detection product
Not, rejected for defect ware and presumptive instruction data are provided.
The specific embodiment of lighting system is：Different with form according to the material of product, foreign matter, foreign matter is attached in bottle
It may be three kinds of bottom of bottle, suspension and side wall states position, in order to realize comprehensive foreign matter Image Acquisition, select multi-angle
The method of composite illuminating.
Meanwhile in order to meet the detection of the elongated foreign matter such as fiber, hair, rotating illuminating can be increased under conditions of permission
And image capture device.Body to be checked follows conveyer belt to rotate, and ensures the arrangement of foreign matter order with horizontal (the big ruler of its longest one side
Very little dimension) at least one surface of position is to light source and image capture device, in this way, also can reliably be detected even if small foreign matter
Come.
The specific embodiment of image capturing system is：Short-wave infrared camera body relatively to be checked, the orientation angles of light source
Relation, can determine according to lighting simulation result, guarantee to collect the short-wave infrared polarization characteristic of maximum, improve polarization and know
Other sensitivity, as shown in Figure 3.
The specific embodiment of data handling system is：Data handling system is responsible for the polarization figure of polyphaser, multichannel
As data are merged, and the parsing of the multispectral polarization characteristic of foreign matter is completed, as shown in Figure 4.In this technical solution, due to base
In the polarization characteristic of foreign matter short infrared wave band, foreign matter differs greatly with surrounding liquid polarization characteristic, gray level image is filtered
Ripple and binaryzation can realize the feature recognition of foreign matter.By adjusting the intensity of illumination light, the exposure of indium GaAs camera, data
Transmission can control within 50ms, data processing can by specialty hardware system realize, with meet single station exposure,
Data transfer and data processing total time are less than 150ms.
The specific embodiment of target identification system is：After infrared, the polarization characteristic of target are effectively extracted, target
Identification belong to ripe image processing techniques, according to existing characteristic information, by setting suitable threshold value and matching algorithm,
The identification of foreign matter quantity, size can be achieved, and foreign body eliminating director data is provided.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
