Description
Technical field
The present invention relates to electronic imaging detection method, especially a kind of electronics images capture technique is in industrial product quality inspection
Application process.
Background technology
At present, image comparison technology have been able to realize two images are contrasted, and judge two images whether phase
Together, such as face recognition technology, but application of the technology in industrial products detection at present is less, and such as current pulp goods are in hot pressing
After sizing, generally also need to, by trimming and detection program, in program is detected, mainly carry out the surface of pulp goods
Optical detection, such as checks that the surface of product is no there are stain, edge incompleteness and metal residual, examining the product of qualification can fill
Case shipment, defective work then need to carry out repair process or directly return to mashing.Existing detection method is generally mainly by human eye
Observation detection, this detection method is there are larger subjectivity, and observation be easy to cause visual fatigue to worker for a long time, influences
The accuracy of detection.The Chinese invention patent of Application No. 201410546478.4 discloses a kind of dixie cup defective vision detection side
Method and system and device, include the following steps：Paper is gathered in real time using the USB capture cards and CCD camera lenses that are connected with embedded system
Cup image；Gray-scale map is converted the image into, adaptive threshold fuzziness and contours extract positioning dixie cup position are utilized in gray-scale map；
Utilize boundary chain code extraction algorithm positioning dixie cup rim of a cup region；Using contours extract and loop truss positioning dixie cup bottom of a cup region, and
Further positioning paper cup sidewall region；Ultimately generate a width dixie cup mark figure, including four parts：Paper cup mouth region domain, dixie cup
Sidewall areas, paper cup bottom contour area and paper cup bottom region, perform different zones corresponding different defect algorithms and carry out
Detection.Although the invention realizes the automation optical detection to dixie cup, but since its different zones uses different defect algorithms,
Therefore image processing process is cumbersome, it is difficult to efficient output testing result.
Given this present invention is proposed.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind to utilize image comparison technology, to judge paper
Application process of the whether qualified electronics images capture technique of milk products in industrial product quality inspection, to substitute artificial detection, and
It is fast with detection speed, the characteristics of accuracy rate is high.
In order to realize the purpose, the present invention adopts the following technical scheme that：
A kind of application process of electronics images capture technique in industrial product quality inspection, comprises the following steps：
The first step, obtains the surface image of product to be detected, and utilizes Edge extraction algorithm, by the image of product to be detected
Extracted from background；
Second step, the image extracted is contrasted with the certified products image prestored, and exports comparing result.
According to comparing result, if the difference of two images contrast is less than setting value, qualified judgement is just exported as a result, such as
The difference of fruit two images contrast is more than setting value, just exports underproof judgement result；The comparing result is inputted to described
Handling device, for controlling handling device that product to be detected are correspondingly moved into certified products lay down location or defective work lay down location.
In the first step, obtain the surface image of product to be detected by way of taking pictures, the product to be detected by two into

The handling device coordinates with imaging device, to get the upper surface figure of product to be detected in first imaging device
As after, second imaging device is set to get the lower surface images of product to be detected by movement product to be detected.
The handling device has multiple stop positions, is respectively, the first image space, the second image space, certified products
Placement location and defective work placement location；Handling device picks up product to be detected in the first image space, and is moved to
Two image spaces, after the imaging of the second image space, product to be detected are moved to certified products and put by handling device according to comparing result
Seated position or defective work placement location.
For the product to be detected in the first image space, first imaging device obtains the upper surface image of product to be detected,
For the product to be detected in the second image space, second imaging device obtains the lower surface image of product to be detected
In the first step, described image Boundary extracting algorithm is Sobel edge detection operators, is comprised the following steps,
Do intensity-weighted computing in 3 × 3 neighborhoods centered on pixel, each pixel of synthetic image it is upper and lower,
The weighted sum of left and right adjoint point gray scale, the weights close to template center are larger, appropriate selected threshold λ, if S (i, j)>λ, then recognize
It is marginal point for point (i, j).
In second step, the process of image comparison includes, and border judges and surface blot judges；
The border is judged as, the border of product to be detected and the border of certified products is carried out registration contrast, if registration
More than setting value, then the edge of product to be detected is qualified；
The surface blot is judged as, the image of product to be detected carried out gray proces, and with the gray level image of certified products
Contrasted, according to both luminance differences, obtain the stain on product to be detected, set if the area of each stain is respectively less than
Value, then the surface blot amount of product to be detected is qualified；
If the surface blot amount and edge of product to be detected are all qualified, the product to be detected are judged for qualification, otherwise for not
It is qualified.
When being imaged to product to be detected, light supply apparatus is opened, to illuminate the surface of product to be detected.
After technical solutions according to the invention, following beneficial effect is brought：
The present invention obtains the image of product to be detected using imaging device, and by the certified products image comparison with prestoring, with
Judge whether product to be detected are qualified, have the advantages that judging result is accurate, processing speed is fast, effectively overcome in human eye detection and deposit
Visual fatigue and the problems such as easily influenced by subjective factor.In addition, judging result is directly used in the movement of control handling device,
Handling device is set to be automatically performed the work such as carrying and the classification placement of product to be detected, to substitute hand labor, and handling device
Cooperate with imaging device, by mobile pulp goods, imaging device is obtained complete pulp goods figure from different perspectives
Picture, substantially increases the efficiency of work.
