In figure, 1. White LED light source, 2. ultraviolet source, 3.X is to polarizing coating, 4. tube stand, 5.Channel glass, 6. multi-color cord array camera, 7.Y is to polarizer, 8.U shape lampshade, 9. measured object.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure of a kind of Polarization Detection system for different fine cleaning machine that the utility model provides is as Fig. 1Shown in, comprising the detection components that is positioned at measured object 9 both sides, every group of detection components comprises ultraviolet source 2And be positioned at the White LED light source 1 of ultraviolet lamp tube 2 away from measured object 9 one sides, White LED light source1 front is provided with X to polarizing coating 3, and White LED light source 1 is established away from a side of ultraviolet source 2Be equipped with multi-color cord array camera 6, the camera lens front of multi-color cord array camera 6 is provided with Y-direction polarizer 7.
White LED light source 1 is fixed on 8 li, the U-shaped lampshade with rectangle light inlet window, and X is to polarizing coating3 are arranged on light inlet window outer surface, are equipped with the U with rectangle light inlet window above at White LED light source 1Shape lampshade 8, U-shaped lampshade 8 removes light inlet window by White LED light source 1 and all shields with the light of exterior domainCover, allow light only penetrate from light inlet window; On the light inlet window of lampshade, assemble polarization angle and be the X of 0 ° to partiallyVibrating diaphragm 3, makes the light that White LED light source 1 sends all be converted into X by this X to polarizing coating 3Axial polarised light, these polarization lights are radiated on measured object 9 by transparent channel glass.
U-shaped lampshade 8 and ultraviolet source 2 are fixed on tube stand 4.
Also comprise the channel glass 5 between measured object 9 and detection components.
Example, White LED light source 1 and ultraviolet source 2 can be respectively White LED fluorescent tube andUltraviolet lamp tube.
A kind of Polarization Detection system for different fine cleaning machine of the present utility model takes into full account design costRequire and polarization signal feature with the characteristic of early stage different fine cleaning machine detection mode and in conjunction with Polarization Detection,Ultraviolet is detected with Polarization Detection and shares same detecting unit, adopt White LED light source as polarizationThe background light source detecting, polarized light source and polarization image gather the both sides of camera in measured object, cameraReal-time Collection sees through the polarized light image of measured object, then cotton by the different characteristic identification of polarization imageThe mulch film impurity containing in spending. Example, light source mounting bracket that can be in same detecting unitOn the polarized light source of three ultraviolet light sources and a White LED light source is installed, polarized light source is installedIn collected by camera image visual field just below as polarization background light source, three ultraviolet light sources are distributed inThe both sides up and down of polarized light source are used as fluorescence excitation. Polarization Detection adopts transmitted ray to carry out, glimmeringLight detects and adopts the reverberation of ultraviolet excited fluorescence to detect.
Polarization image collection design mainly realizes from polarization signal screening and collected by camera image two aspects,According to different measured objects 9 (cotton, mulch film) characteristic of transmitted light under polarizing light irradiation, polarization letterNumber screening utilizes the Y-direction of 90 ° of (Y-axis) polarization directions that multi-color cord array camera 6 camera lenses assemble inclined to one side aboveThe sheet 7 that shakes completes. Thereby the polarised light of well-known directions X cannot produce by the polarizer of Y-directionRaw frosting phenomenon, and transparent mulch film is under the irradiation of polarised light, the polarization of light angle that it sees through can be sent outRaw deflection, the polaroid before polarization angle and the camera lens of transmitted light is no longer 90 ° of angles, according to projectionFormula is known, and part light can pass through Y-direction polarizer 7; And cotton belongs to opaque article, itsUnder the irradiation of polarized light source, do not have transmitted ray to pass through, therefore do not have light to pass through Y-direction polarizationSheet 7. According to foregoing description, transparent mulch film, can be at process Y-direction polarizer 7 owing to there being polarization characteristicThe image that rear formation is brighter, the measured object that cotton etc. do not have polarization characteristic is very dark image.
In Polarization Detection system, IMAQ completes with high-speed color line-scan digital camera 6. Ultraviolet ray swashsThe fluoroscopic image of sending out is mainly taking blue light as main, and polarised light sees through when mulch film, and the edge of mulch film is to redLook, green polarization light produce larger deflection, thereby can at camera after Y-direction polarizer 7Collect redness or green image, the centre of mulch film is roughly suitable to the deflection angle of light of all kinds,So camera can collect brighter image after Y-direction polarizer 7. Utilize color camera collectionThe RGB rgb image forming can farthest retain these information, not only can effectively identifyThe mulch film of the different fibre of fluorescence and various shapes, and can effectively reduce veiling glare and natural daylight to imageInterference.
