Under above-mentioned three-dimensional combined light source polishing environment, the image for shooting magnetic shoe is as shown in Figure 4.From fig. 4, it can be seen that it claps
Its defects of can identifying magnetic shoe surface well of the image taken the photograph, but surface texture has and slightly interferes, and works as the intensity of light source
It increases to very by force, defect will be brightened, lead to not defect is presented.Surface defects detection is wanted to reach preferable imaging in magnetic shoe
Effect, then need light source to reach certain intensity, thus will appear more noise, fully relies on software algorithm denoising, not only

Continue experiment to find, although making an uproar in shooting magnetic shoe image under sheen treated three-dimensional combined light source environment
Point significantly reduces, and can substantially tell imaged object surface defect, but there are a lot oves as shown in Figure 6 in its image
Light belt.Light belt width directly affects effective detection zone of image, therefore need to as possible reduce under the premise of picture quality is ensured
The width of light belt.Present invention illumination imaging optimization device is analyzed by optical theory, is set in third light source 300 and external imaging
Polarised light is added in standby and filters out component, and filtering out technology using polarised light reduces light belt width, to realize enhancing picture contrast
Purpose, specifically, polarised light, which filters out component, can include polarizer.
Usually, body surface reflex components are mainly made of diffusing reflection flap, minute surface flap and minute surface spike, distribution
Situation is related to the roughness of reflecting surface.For the defective position in magnetic shoe surface, surface roughness is much larger than incident light
Line wavelength, in reflex components based on diffusing reflection flap, minute surface flap and minute surface spike are less, diffusing reflection are can be considered, for magnetic
Watt flawless position in surface, surface roughness are much smaller than incident ray wavelength, with minute surface flap and minute surface in reflex components
Based on spike, diffusing reflection flap is less, can be considered mirror-reflection.Mirror-reflection can keep the polarizability of light, and diffusing reflection
Polarised light can be made to become natural light.
According to Malus' law, if the amplitude of original incident light is A0, then incident intensity be：
I0=A0 2。
When linearly polarized light is impinged perpendicularly on polarizer, electric vector vibration direction and polarizer shake the angle in direction thoroughly
For α, electric vector is shaken the consistent parallel component A in direction thoroughly with polarizerPPolarizer can be penetrated, and electric vector is shaken thoroughly with polarizer
The vertical component A in directionnIt is absorbed by the polarizer and filters out.Therefore, transmitted intensity is：
I=Ap 2=(A0cosα)2, that is, I (α)=I0cos2α。
Natural light is by the transmitted intensity after polarizer：
I (α)=0.5I0。
When not having polarizer, the light of vertical light source transmitting is the light of natural light, zero defect position and defective locations reflection
It is natural light.Assuming that the loss late for the light for receiving and reflecting is respectively k and t.
When the luminous intensity of vertical light source is IilDuring=α, the luminous intensity that magnetic shoe receives is：
Iol=(1-k) α.
The intensity of reflected light that camera lens receives zero defect position minute surface is：
Ipl=(1-t) * (1-k) α.
Camera lens receive defective locations minute surface the intensity that diffuses be：
Iql=(1-t) * (1-k) α.
Assuming that the defects of can telling other than light belt substantially at this time, strong reflective light on imaged object surface (magnetic shoe surface)
The width of band is B, then the intensity of reflected light that light belt width is proportional to the zero defect position minute surface of camera lens reception is：
B1∝Ip1=(1-t) * (1-k) α.
When vertical light source and camera lens all install polarizer additional, vertical light source becomes polarised light, and zero defect position is anti-for minute surface
It penetrates, reflected light is polarised light, and defective position is diffusing reflection, and reflected light is natural light.Assuming that the light of reception and reflection
Loss late is respectively k and t, then when increase luminous intensity to Ii2During=4 α, the luminous intensity of magnetic shoe is：
Io2=0.5 (1-k) * Ii2=2 (1-k) α.
The intensity of polarization light that camera lens receives zero defect position mirror-reflection is：
Ip2=(1-t) Io2cos2α=2 (1-t) (1-k) a cos2α。
Camera lens receive defective locations mirror-reflection natural light intensity be
Iq2=0.5 (1-k) Io2=(1-t) (1-k) a=Iq1。
Light belt width is：
B2∝Ip2=2 (1-t) (1-k) a cos2α。
It enables
Ip2＜ Ip1=(1-t) (1-k) a.
Acquire 45 ° of 135 ° of ＜ α ＜, B2＜ B1.At this point, the intensity of the defects of camera lens receives position reflected light is sufficiently large, it is
(1-t) * (1-k) a meets the requirement of defect imaging, but the intensity of zero defect position reflected light that camera lens receives is less than (1-t) *
(1-k) a, by B1∝Ip1=(1-t) * (1-k) α can be obtained：Light belt width is less than the light belt width not added before polarizer.As it can be seen that
Polarizer is installed additional before vertical light source (third light source 300) and camera lens, and passes through reasonable rotatory polarization piece, can camera lens be connect
The defects of receipts, the luminous intensity of position mirror-reflection was constant, and the luminous intensity of zero defect position mirror-reflection dies down.
Technology is filtered out using polarised light to have the following advantages：
1st, increase detectable range
In the case where not weakening defect recognition ability, reduce light belt width, increase the detectable range of image.
2nd, increase picture contrast
During imaging, in the case where the luminous intensity of defective locations is constant, the luminous intensity of zero defect position is reduced, it can be effective
Increase the contrast of image.
3rd, reduce noise
Due to reducing the luminous intensity of zero defect position, so effectively filtered out the zero defect position of imaged object surface
Noise signal.Filtering out light belt width after technology using polarised light being obviously reduced can be obtained by formula and experiment：When α=90 °, light
Band is most narrow, but image is most dark, influences detection result；When α=70 °, light belt width during α=90 ° than having increased slightly, picture quality
Preferably, most of defect can be identified；When α=50 °, the soft degree of image, brightness make moderate progress, and can have
The defects of effect identification dark space, light belt width ratio also have apparent reduction before adding polarizer, and imaging effect is optimal.Polarised light is added to filter
Except the image after component (polarizer) is as shown in Figure 7.
