Fig. 4 is the figure for schematically showing the view data as the prepreg 10 taken by camera device 120.

Camera device 120 received from the flawless part of prepreg 10 by the diffusing of being reflected of prepreg 10 and Via the prepreg 10 with translucency by diffusing that the supporting surface 141 of support member 140 is reflected.Therefore, utilizing In the view data of prepreg 10 captured by camera device 120, in flawless part, can be seen via prepreg 10 To the mode of the supporting surface 141 of support member 140, the color of the supporting surface 141 of support member 140 is shown.In this embodiment party In formula, because the supporting surface 141 of support member 140 is cyan, therefore the prepreg 10 in the photographed images of camera device 120 Flawless part is cyan.

For the defect A of prepreg 10, the diffusing reflection rate for the irradiation light irradiated from light source 130 is than flawless part Diffusing reflection rate is high.Therefore, the light income ratio for being reflected and being received by camera device 120 by the defect A of prepreg 10 is by zero defect The part light income that reflects and received by camera device 120 it is big.Therefore, as shown in figure 4, in the view data of prepreg 10 In, existing defects A part is brighter than flawless part.

It should be noted that the diffusing reflection rate for the irradiation light from light source 130 is got over Gao Ze and connect by camera device 120 The reasons why light income of receipts is bigger is as follows.Diffusing reflection rate height means diffusing reflection namely macroscopically seen with reflection law independently Degree along the reflection of the form of all directions diffused light is high.On the other hand, light source 130 (130a and 130b) and camera device 120 Position relationship be that irreflexive degree is higher namely macroscopically see with reflection law independently along the form of all directions diffused light Reflection the more high then camera device 120 of degree the bigger position relationship of light income.Therefore, for the photograph from light source 130 Penetrate the light income that the diffusing reflection rate more Gao Ze of light received by camera device 120 bigger.

In addition, camera device 120 receives unrestrained anti-from the surface of prepreg 10 from the existing defects B of prepreg 10 part Penetrate light and via the prepreg 10 with translucency by diffusing that foreign matter is reflected.Therefore, in the figure of camera device 120 As in data for prepreg 10 existing defects B part, with via prepreg 10 it can be seen that foreign matter mode is shown The color of foreign matter.For example, when the foreign matter of black is mixed into the inside of prepreg 10 and produces defect B, can be seen in photographed images To the defect B of shade appearance (referring to Fig. 4).

As described above, in the view data of prepreg 10, existing defects A part is brighter than flawless part.Therefore, In view data, the brightness of the pixel of the flawless part of brightness ratio of the pixel of existing defects A part is high.

In addition, in using the view data captured by camera device 120, such as existing and being produced due to black foreign matter Defect B part is darker than flawless part.Therefore, in this situation, the pixel of existing defects B part in view data The brightness of the pixel of the flawless part of brightness ratio is low.

Therefore, the test section 152 of check device 150 for example precomputes the zero defect in the view data of prepreg 10 Part pixel mean flow rate, and the brightness of each pixel based on view data and the mean flow rate that precomputes Difference detects defect.Test section 152 is defect A for example by the high pixel detection of brightness ratio mean flow rate in view data.In addition, Test section 152 is defect B for example by the low pixel detection of brightness ratio mean flow rate in view data.

In addition, test section 152 can calculate brightness and the difference of mean flow rate of each pixel in view data, and will be bright Degree it is higher than mean flow rate and and the difference of mean flow rate be that more than first threshold set in advance pixel detection is defect A.Separately Outside, test section 152 can brightness ratio mean flow rate is low and and mean flow rate difference to be more than Second Threshold set in advance Pixel detection is defect B.By the way that the difference of the brightness of each pixel and mean flow rate and threshold value are compared to detect defect, so that The flase drop of defect can be reduced.

So, the test section 152 of check device 150 can be based on the shooting figure obtained by utilization camera device 120 (what is be mixed into is different to distinguish and detect the defect A present in prepreg 10 (crackle on top layer) and defect B for the view data of picture Thing) etc. defect.In the above example, to detecting that the situation of the defect B as black foreign matter is illustrated, but in detection conduct In the case of the defect B of foreign matter beyond black, brightness that also can be based on the pixel of existing defects B part with it is flawless The difference of the brightness of partial pixel detects defect B.

As described above, the inspection system 100 in first embodiment, can detect the preimpregnation as check object thing The defect of material 10, while can differentiate to the species of defect.

In addition, in inspection system 100, being carried out with the gap between the conveyer belt 112 of first conveyer belt 111 and second pre- The mode of the inspection of leaching material 10 sets light source 130 and camera device 120.By such structure, can accurately it carry out pre- The defect inspection of leaching material 10, is influenceed without bumps on surface by the conveyer belt 112 of first conveyer belt 111 and second etc..

In addition, prepreg 10 is supported between the conveyer belt 112 of first conveyer belt 111 and second by support member 140, from And can accurately be checked, scratched without making prepreg 10 be produced between the conveyer belt 112 of first conveyer belt 111 and second It is bent.

It should be noted that if the supporting surface 141 of support member 140 is, for example, the netrual colour of black, white or grey When, in using the view data captured by camera device 120, it is possible to existing defects A or defect B part with it is flawless Partial difference can be indefinite.Therefore, in the present embodiment, by the way that the supporting surface 141 of support member 140 has been set into coloured silk Color, so as to the difference clearly brought due to the presence or absence of defect as described above and accurately detects defect.

Here, the view data of the photographed images captured by camera device 120 is for example had with 0~255 by each pixel Numerical value come represent R (red), G (green), B (indigo plant) each color rgb value.Therefore, test section 152 can be according to support member Among the color of 140 supporting surface 141, the value of each color included using rgb value, defect part and flawless portion Point the value of luminance difference maximum color detect defect.

For example, when the supporting surface 141 of support member 140 is set into blueness, can be seen for the crackle due to top layer To the defect A for appearance of turning white detection, the R of the G channel datas using the G values with each pixel or the R values with each pixel leads to Track data.By using G channel datas or R channel datas, so as to clear and definite defect A and the difference of zero defect part, and carry High detection sensitivity.In addition, in this case, such as the detection for the defect B as black foreign matter, by using with each The channel B data of the B values of pixel, so as to clear and definite defect B and the difference of zero defect part, and improve detection sensitivity.

In addition, in the explanation of first embodiment, being for example illustrated for white light is irradiated for light source 130, but The irradiation light of light source is not limited to white light, the wavelength of the color of the supporting surface 141 comprising support member 140.For example, when branch When the color in support face 141 is blueness, light source can be the light of other colors comprising blue light, can be cyan light, magenta Light.

Here, the R values of each pixel in view data are not influenceed by the blue light irradiated from the first light source 230, and It is the light income received by camera device 220 according to the red light included in the white light irradiated from secondary light source 240 Determine.Therefore, blue light from the first light source 230 on existing defects A part is received by camera device 220 Light income increase, the R values included in view data will not also become big.Therefore, lack as shown in figure 8, existing in R channel datas Falling into A part will not be influenceed by blue light.

Then in step S207, test section 253 is calculated as the color of conduct first acquired by color information obtaining section 252 The difference of the channel B data of multimedia message and R channel datas as the second color information.Then in step S208, test section 253 Detect the defect of prepreg 10.

Test section 253 is directed to all pixels included in view data and calculated as the first color information in step S208 Channel B data with as the second color information R channel datas difference ((B values-R values) in same pixel).Hereinafter, will The data of the channel B data so obtained and the difference of R channel datas are referred to as B-R channel datas.

As described above, in channel B data, the value of defect part A is bigger (referring to Fig. 7) than the value of zero defect part.With this Relatively, in R channel datas, the value of defect part A is smaller than the value of zero defect part (referring to Fig. 8).Therefore, in B-R port numbers In, the difference of the value of defect part A and the value of zero defect part than channel B data and R channel datas each in defect part A Value and zero defect part value difference it is big.

For example, in channel B data, if the value of each several part of (defect A, defect B, zero defect) is (250,50,120). In addition, in R channel datas, if the value of each several part of (defect A, defect B, zero defect) is (50,50,120).In this situation In, for B-R channel datas, the value of each several part of (defect A, defect B, zero defect) is (200,0,0).

Therefore, in B-R channel datas, the difference of the value of defect part A and the value of zero defect part is 200, than channel B number The difference (130) of the value of defect part A in and the value of zero defect part is big.In addition, in B-R channel datas, defect part A Value and the difference of value of zero defect part be 200, than the defect part A in R channel data value and zero defect part value it Poor (70) are big.

Therefore, when the difference of value of the test section 253 based on defect part A and the value of zero defect part is to detect defect A, lead to The larger B-R channel datas of difference using the value of defect part A and the value of zero defect part are crossed, so as to accurately detect out Defect A.In addition, in B-R channel datas, the flawless portion of channel B data and each self-contained prepreg 10 of R channel datas Brightness spot in point is eliminated.Therefore, the B-R channel datas that test section 253 is eliminated by using brightness spot, so as to subtract Few defect A flase drop.

In addition, test section 253 by the pixel value in channel B data it is smaller than the average value of zero defect partial value and with it is intact The difference for falling into the average value of partial value is detected as defect B for part more than threshold value set in advance.

As described above, the inspection system 200 in second embodiment, can detect the preimpregnation as check object thing The defect of material 10 and the species for differentiating defect.In addition, by according to as the view data captured by camera device 220, acquirement work Channel B data for the first color information simultaneously obtain and are used as the R channel datas of the second color information and scarce to detect based on its difference Fall into, so as to improve defect A accuracy of detection and reduce flase drop.

Then, to the 3rd embodiment, the 4th embodiment, the 5th embodiment, the 6th embodiment, the 7th embodiment party Formula and the 8th embodiment are illustrated.

Figure 11 is the figure for the flow chart for representing the defects detection processing in the 3rd embodiment.

As shown in figure 11, in the defects detection processing of inspection system 1100, first in step S1101, conveying device 1110 convey prepreg 1010 from first conveyer belt 1111 towards the 3rd conveyer belt 1113.

Then, in step S1102, the first 1121 pairs of camera device is in the conveyer belt 1112 of first conveyer belt 1111 and second Between the prepreg 1010 that is conveyed of the first camera watch region imaged.As described above, the first of the first camera device 1121 Camera watch region is arranged between the conveyer belt 1112 of first conveyer belt 1111 and second, and the first camera device 1121 is to prepreg The part that the supporting surface 1141 of 1010 supported member 1140 is supported is imaged.First camera device 1121 is by defeated The prepreg 1010 for sending device 1110 to be conveyed continuously is imaged, so that the entirety to prepreg 1010 is imaged.

In step S1103, the defects detection portion 1162 of check device 1160 is taken the photograph based on image acquiring section 1161 from first As the view data (hereinafter referred to as the first view data) for the prepreg 1010 that device 1121 is obtained, lacking for prepreg 1010 is detected Fall into.

Figure 12 is schematically shown as the first picture number of the prepreg 1010 taken by the first camera device 1121 According to figure.

First camera device 1121 receives the diffusing reflection from prepreg 1010 from the flawless part of prepreg 1010 Light and via the prepreg 1010 with translucency by diffusing that the supporting surface 1141 of support member 1140 is reflected.Cause This, in the first view data of prepreg 1010, in flawless part, with via prepreg 1010 it can be seen that support The mode of the supporting surface 1141 of part 1140, shows the color of the supporting surface 1141 of support member 1140.In present embodiment In, because the supporting surface 1141 of support member 1140 is cyan, therefore presoaked in the photographed images of the first camera device 1121 The flawless part of material 1010 is cyan.

The defect AA of prepreg 1010 reflects the irradiation light from the first light source 1131 in the same manner as flawless part.Cause This, the light income received by the defect AA of prepreg 1010 by the first camera device 1121 from zero defect part by first with being imaged The light income that device 1121 is received is equal amount.Therefore, as shown in figure 12, in the first view data of prepreg 1010, Existing defects AA part has the brightness equal with zero defect part.

The defect BB of prepreg 1010 has the state turned white by internal crackle.First camera device 1121 is from preimpregnation The existing defects BB of material 1010 part receives the surface from prepreg 1010 and diffused and via with translucency Prepreg 1010 and by diffusing that defect BB reflects.Therefore, in the first view data of prepreg 1010, existing defects BB part is brighter than flawless part.

In addition, the first camera device 1121 is received from the existing defects CC of prepreg 1010 part comes from prepreg 1010 Surface diffuses and via the prepreg 1010 with translucency by diffusing that foreign matter is reflected.Therefore, first In first view data of camera device 1121, for the existing defects CC of prepreg 1010 part, with via prepreg 1010 and it can be seen that foreign matter mode shows the color of foreign matter.For example, when the foreign matter of black is mixed into the inside of prepreg 1010 And when producing defect CC, defect CC shows as shade in the first view data.

As described above, in the first view data of the prepreg 1010 obtained by using the first camera device 1121, depositing In defect BB and defect CC part, brightness from zero defect part or color are different.

Therefore, the defects detection portion 1162 of check device 1160 for example precomputes the first image in prepreg 1010 The mean flow rate of the pixel of flawless part in data, and the brightness of each pixel based on the first view data and meter in advance The mean flow rate that calculates relatively detects defect.Defects detection portion 1162 is for example average bright by brightness ratio in the first view data The high pixel detection of degree is defect BB.In addition, defects detection portion 1162 is for example by brightness ratio mean flow rate in the first view data Low pixel detection is defect CC.

In addition, defects detection portion 1162 can for example calculate the brightness of each pixel in the first view data with it is average bright The luminance difference (i.e. " brightness of each pixel "-" mean flow rate ") of degree, and defect BB and defect CC is detected based on luminance difference.Defect Test section 1162 for example by first threshold set in advance (>0) and Second Threshold (<0) it is compared with luminance difference, by luminance difference It is defect BB for pixel detection more than first threshold.In addition, being that pixel detection below Second Threshold is defect by luminance difference CC。

So, the defects detection portion 1162 of check device 1160 can be based on from acquired by the first camera device 1121 The first view data detect the defect BB present in prepreg 1010 and defect CC.In the above example, detection is made Situation for the defect CC of black foreign matter is illustrated, and even for the defect CC as the foreign matter beyond black, also can The brightness of the pixel of enough parts based on existing defects CC detects defect with the difference of the brightness of the pixel of zero defect part CC。

The flow chart of the defects detection processing shown in Figure 11 is returned to, in step S1104, the second 1122 pairs of picture device exists The prepreg 1010 that the second camera watch region between second conveyer belt 1112 and the 3rd conveyer belt 1113 is conveyed is imaged.Such as It is upper described, the second camera watch region of the second camera device 1122 be arranged on the second conveyer belt 1112 and the 3rd conveyer belt 1113 it Between.Second camera device 1122 to the prepreg 1010 conveyed by conveying device 1110 by continuously imaging, so as to pre- The entirety of leaching material 1010 is imaged.

In step S1105, the defects detection portion 1162 of check device 1160 is taken the photograph based on image acquiring section 1161 from second As the view data (hereinafter referred to as the second view data) for the prepreg 1010 that device 1122 is obtained, lacking for prepreg 1010 is detected Fall into.

Figure 13 is schematically shown as the second picture number of the prepreg 1010 taken by the second camera device 1122 According to figure.

Second camera device 1122 receives the surface from prepreg 1010 from the flawless part of prepreg 1010 Specular light.In addition, in existing defects CC part, same with flawless part, the surface of prepreg 1010 will come from The irradiation light mirror-reflection of secondary light source 1132.Therefore, the second camera device 1122 is from the existing defects CC's of prepreg 1010 Part also receives the specular light on the surface from prepreg 1010 in the same manner as flawless part.

The diffusing reflection rate ratio of the irradiation light from secondary light source 1132 on the defect AA and defect BB of prepreg 1010 without The diffusing reflection rate of the part of defect is high.Therefore, connect from the defect AA and defect BB of prepreg 1010 by the second camera device 1122 The light income of receipts is smaller than the light income received from flawless part by the second camera device 1122.Therefore, as shown in figure 13, exist Existing defects AA and defect BB part are than zero defect part or existing defects CC in second view data of prepreg 1010 Part is dark.

It should be noted that the diffusing reflection rate for the prepreg 1010 of the irradiation light from secondary light source 1132 gets over Gao Ze The reasons why light income that second camera device 1122 is received is smaller is as follows.Diffusing reflection rate height means diffusing reflection namely macroscopic view On see that the degree with reflection law independently along the reflection of the form of all directions diffused light is high.On the other hand, secondary light source 1132 Position relationship with the second camera device 1122 is that irreflexive degree is lower namely then the second shooting is filled closer to mirror-reflection Put 1122 the bigger position relationship of light income.Therefore, overflow for the prepreg 1010 of the irradiation light from secondary light source 1132 It is smaller that reflectivity gets over the light income that Gao Ze received by the second camera device 1122.

Therefore, the defects detection portion 1162 of check device 1160 for example precomputes the second image in prepreg 1010 The mean flow rate of the pixel of flawless part in data, and by the brightness of each pixel of the second view data with precalculating The mean flow rate gone out is compared to detect defect AA and defect BB.Defects detection portion 1162 for example will be bright in the second view data The degree pixel detection lower than mean flow rate is defect AA and defect BB.In addition, defects detection portion 1162 can for example calculate The luminance difference relative to mean flow rate of the brightness of each pixel in two view data is (i.e. " brightness of each pixel "-" average bright Degree "), and luminance difference is detected for the pixel below threshold value set in advance as defect AA and defect BB.

So, the defects detection portion 1162 of check device 1160 can be based on being taken using the second camera device 1122 The second view data detect the defect AA present in prepreg 1010 and defect BB.

The flow chart of the defects detection processing shown in Figure 11 is returned to, when utilization defects detection portion 1162 is not from prepreg Detected in 1010 when any defect AA, defect BB and defect CC (step S1106 is no), processing advances to step S1107. In step S1107, the control tactics mechanism 1150 of division 1163 will not detect the prepreg 1010 of defect from the 3rd conveyer belt 1113 are discharged to the first pallet 1151 and terminate processing.

Defect AA, defect BB and defect CC are detected from prepreg 1010 using defects detection portion 1162 in addition, working as Any one when (step S1106 is yes), processing advance to step S1108.In step S1108, the control point of division 1163 Class mechanism 1150, is discharged to the second pallet 1152 from the 3rd conveyer belt by the prepreg 1010 for detecting defect and terminates processing.

Here, as described above, the defects detection portion 1162 of check device 1160 is according to utilization the first camera device 1121 institute The first view data shot detects the defect BB and defect CC (step S1103) of prepreg 1010.In addition, according to utilizing second The second view data captured by camera device 1122 detects the defect AA and defect BB (step S1105) of prepreg 1010.This Sample one, for the processing using the first view data and the processing using the second view data, the species of the defect detected It is different.In addition, using different processing (such as by brightness ratio mean flow rate in the step S1103 using the first view data Processing that high pixel detection is defect BB and the processing for being defect CC by the low pixel detection of brightness ratio mean flow rate) detection lacks Fall into BB and defect CC.On the other hand, (for example will be bright using identical processing in the step S1105 using the second view data The processing that the degree pixel detection lower than mean flow rate is defect AA and defect BB) detection defect AA and defect BB.As a result, sharp With the processing time t2 length of the processing time t1 Billy of the processing of the first view data with the processing of the second view data.

Thus, for example in the transport path of prepreg 1010, being taken the photograph if being configured to the second camera device 1122 first As the upstream side of device 1121 is imaged, then overall processing time can increase.In this case, if the first shooting filled When putting the conveying of prepreg 1010 between 1121 the first camera watch region and the second camera watch region of the second camera device 1122 Between be set to t3, then as shown in Figure 14 A, according to needed for the defects detection of the first view data and the second view data necessity at The reason time is T21=t1+t3.

On the other hand, in the inspection system 1100 of present embodiment, in the transport path of prepreg 1010, it is configured to First camera device 1121 is imaged in the upstream side of the second camera device 1122.According to such structure, such as Figure 14 B institutes Show, the necessary processing time according to needed for the defects detection of the first view data and the second view data is T12=t1, can More above-mentioned necessary processing time T21 (=t1+t3) is shortened.

As described above, the inspection system 1100 in the 3rd embodiment, can be based on utilizing the first camera device 1121 and second image captured by camera device 1122 detect the defect of the prepreg 1010 as check object thing.Separately Outside, by making the first camera device 1121 enter in the upstream side of the second camera device 1122 in the transport path of prepreg 1010 Row shooting, so as to shorten the time needed for defects detection processing and improve productivity.

In addition, in the inspection system 1100 of the 3rd embodiment, with the conveyer belt 1111 of conveying device 1110 and The mode for the inspection that gap between 1112 carries out prepreg 1010 sets the first camera device 1121.In addition, to be filled in conveying The mode for putting the inspection that the gap between 1110 conveyer belt 1112 and 1113 carries out prepreg 1010 sets the second camera device 1122.According to such structure, the inspection of the defect of prepreg 1010 can be accurately carried out, without by conveying device The influence of the bumps of conveyor belt surface on 1110 etc..

Figure 18 is the figure for the flow chart for representing the defect inspection processing in the 5th embodiment.

As shown in figure 18, in the defects detection processing of inspection system 1300, first in step S1301, conveying device 1110 convey prepreg 1010 from first conveyer belt 1111 to the 4th conveyer belt 1114.Then, in step S1302, first The preimpregnation that 1121 pairs of first camera watch regions between the conveyer belt 1112 of first conveyer belt 1111 and second of camera device are conveyed Material 1010 is imaged.

In step S1303, the color information obtaining section 1164 of check device 1160 is according to the institute of the first camera device 1121 The first view data shot obtains the first color information.

Here, using the first view data of the prepreg 1010 captured by the first camera device 1121 for example by each picture Element have with 0~255 numerical value come represent R (red), G (green), B (indigo plant) each color rgb value.Color information obtaining section 1164 Obtain blue channel B data corresponding with the blue light irradiated from the first light source 1131a and 1131b and the 4th light source 1134 (the B values of each pixel) is used as the first color information.So, color information obtaining section 1164 is obtained according to the first view data The color included in the wavelength region of the blue light irradiated from the first light source 1131a and 1131b and the 4th light source 1134 Data are used as the first color information.

Figure 19 is to schematically show the first picture number using the prepreg 1010 captured by the first camera device 1121 According to the figure of (channel B data).

, will be from the first light source 1131a and 1131b institutes in the same manner as flawless part for the defect AA of prepreg 1010 The blue light reflection of irradiation.Therefore, the light income for the defect AA from prepreg 1010 that the first camera device 1121 is received It is equal with the light income from zero defect part.Therefore, as shown in figure 19, for channel B data, in existing defects AA part Equal brightness is shown with zero defect part.

For the defect BB of prepreg 1010, from the diffusing reflection rate of the first light source 1131a and 1131b blue lights irradiated Diffusing reflection rate than zero defect part is high.Therefore, the indigo plant irradiated from the first light source 1131 received by the first camera device 1121 The light income from defect BB of coloured light is bigger than the light income from zero defect part.Therefore, as shown in figure 19, in channel B number In, existing defects BB part is brighter than zero defect part in prepreg 1010.

In addition, for the defect CC of prepreg 1010, the irradiation light from the 4th light source 1134 is blocked by foreign matter.Therefore, The light income of the blue light included in the irradiation light from the 4th light source 1134 received for the first camera device 1121, Existing defects CC part is smaller than zero defect part.Therefore, as shown in figure 19, in channel B data, existing defects CC part It is darker than zero defect part.

It should be noted that because the reflected light of the irradiation light from the first light source 1131a and 1131b is with coming from the 4th light The transmitted light sum of the irradiation light in source 1134 is the first view data, therefore as shown in figure 19, in channel B data, is existed scarce The part for falling into BB is brighter than zero defect part.The part that additionally, there are defect CC is darker than zero defect part.

In addition, in step S1304, color information obtaining section 1164 according to captured by the first camera device 1121 first View data obtains the second color information.During color information obtaining section 1164 obtains the white light with being irradiated from the 4th light source 1134 Comprising the corresponding red R channel datas (the R values of each pixel) of red light be used as the second color information.So, color Multimedia message obtaining section 1164 according to view data obtain it is among the irradiation light from the 4th light source 1134, with from the first light source The data of the color included in the wavelength region of the different red light of the wavelength regions of 1131 blue lights irradiated are as second Color information.

It should be noted that color information obtaining section 1164 can obtain the white light with being irradiated from the 4th light source 1134 In the corresponding green G channel datas (the G values of each pixel) of green light that include as the second color information.In this case, Also the defect of prepreg 1010 can be detected in the same manner as the situation for the use R channel datas that will be described below.

Figure 20 is to schematically show the second picture number using the prepreg 1010 captured by the first camera device 1121 According to the figure of (R channel datas).

The light irradiated from the 4th light source 1134 to the first camera device 1121 is by existing defects AA in prepreg 1010 Part or zero defect part are similarly transmitted.Therefore, the 4th light source is come from for what is received by the first camera device 1121 Light income among red light included in 1134 irradiation light, existing defects AA part and zero defect part is substantially equal. Therefore, as shown in figure 20, in R channel datas, existing defects AA part is shown and zero defect part in prepreg 1010 Equal brightness.

The light irradiated from the 4th light source 1134 to the first camera device 1121 by existing defects BB in prepreg 1010 or Defect CC partial occlusion.Therefore, in the first camera device 1121, for being wrapped in the irradiation light from the 4th light source 1134 The light income of the red light contained, existing defects BB or defect CC part are smaller than zero defect part.Therefore, as shown in figure 20, in R In channel data, existing defects BB and defect CC part are darker than zero defect part in prepreg 1010.

Here, the R values of each pixel in view data are not irradiated by the first camera device 1121 from the first light source 1131 Blue light influence, but the red light included in the light irradiated according to the first camera device 1121 from the 4th light source 1134 Light income determine.Therefore, first is come from by what the first camera device 1121 was received on existing defects AA part The R values included in the light income increase of the blue light of light source 1131, view data will not also become big.Therefore, as shown in figure 20, exist Existing defects AA part will not be influenceed by blue light in R channel datas.

The flow chart of the defects detection processing shown in Figure 18 is returned to, then in step S1305, defects detection portion 1162 is counted Calculate as the channel B data acquired by color information obtaining section 1164 as the first color information with as the second color information R channel datas difference.Then in step S1306, defects detection portion 1162 is based on the first view data and color information is examined Survey the defect of prepreg 1010.

Defects detection portion 1162 is directed to all pixels included in view data and calculated as the first color in step S1305 The channel B data of multimedia message and the difference ((B values-R values) in same pixel) of the R channel datas as the second color information. Hereinafter, the data of the channel B data so obtained and the difference of R channel datas are referred to as B-R channel datas.

As described above, in channel B data, the value of defect BB parts is bigger (referring to Figure 19) than the value of zero defect part.With This is relative, and in R channel datas, the value of defect BB parts is smaller than the value of zero defect part (referring to Figure 20).Therefore, it is logical in B-R In track data, the difference of the value of defect BB parts and the value of zero defect part than channel B data and R channel datas each in defect The difference of the value of BB parts and the value of zero defect part is big.

For example, in channel B data, if the value of each several part of (defect BB, zero defect) is (250,120).In addition, in R In channel data, if the value of each several part of (defect BB, zero defect) is (50,120).In this case, for B-R port numbers According to the value of each several part of (defect BB, zero defect) is (200,0).

Therefore, in B-R channel datas, the difference of the value of defect BB parts and the value of zero defect part is 200, compares channel B The difference (130) of the value of defect BB parts in data and the value of zero defect part is big.In addition, in B-R channel datas, defect BB Partial value and the difference of the value of zero defect part are 200, than value and the zero defect part of the defect BB parts in R channel data The difference (70) of value is big.

Therefore, defect is detected when the difference of value of the defects detection portion 1162 based on defect BB parts and the value of zero defect part During BB, by using defect BB parts value and zero defect part value the larger B-R channel datas of difference, so as to accurate Ground detects defect BB.In addition, in B-R channel datas, channel B data and each self-contained prepreg 1010 of R channel datas Flawless part in brightness spot be eliminated.Therefore, the B-R that defects detection portion 1162 is eliminated by using brightness spot leads to Track data, so as to reduce defect BB flase drop and accurately detect out defect BB.

In addition, test section 1162 by the pixel value in R channel datas it is smaller than the average value of zero defect partial value and with it is intact The difference for falling into the average value of partial value is detected as defect BB or defect CC for part more than threshold value set in advance.

In step S1307, the second 1122 pairs of camera device is between the second conveyer belt 1112 and the 3rd conveyer belt 1113 The prepreg 1010 that is conveyed of the second camera watch region imaged.In step S1308, defects detection portion 1162 is based on image Second view data of the prepreg 1010 that obtaining section 1161 is obtained from the second camera device 1122, detects prepreg 1,010 first The defect AA and defect BB of surface side.

In step S1309, the 3rd 1123 pairs of camera device is between the 3rd conveyer belt 1113 and the 4th conveyer belt 1114 The prepreg 1010 that is conveyed of the 3rd camera watch region imaged.In step S1310, defects detection portion 1162 is based on image 3rd view data of the prepreg 1010 that obtaining section 1161 is obtained from the 3rd camera device 1123, the of detection prepreg 1010 The defect AA and defect BB of second surface side of opposite side simultaneously.

Based on captured by the second view data captured by the second camera device 1122 and the 3rd camera device 1123 The defect AA and defect BB of three view data detection method are identical with above-mentioned 4th embodiment.

When any defect AA, defect BB and defect CC are not detected from prepreg 1010 using defects detection portion 1162 (step S1311 is no), processing advances to step S1312.In step S1312, the control tactics mechanism 1150 of division 1163, The prepreg 1010 for not detecting defect is discharged to the first pallet 1151 from the 4th conveyer belt 1114 and terminates processing.
