(30) work, mechanical gripping finger (33) closure.First cylinder (28) works, and the first cylinder (28) piston rod, which stretches out, drives connecting rod
(29) move up, so as to drive mechanical gripping finger (33) to move up, due to groove (43) limitation, capacitor pin is then outwards rectified by root
Directly, when the first cylinder (28) stroke is maximum, the second cylinder (30) reverse operation, mechanical gripping finger (33) is opened, the first cylinder
(28) reverse operation, mechanical gripping finger (33) returns to original position；Scratch diskette (6) is rotated simultaneously, and whole pin electric capacity is admitted to vision-based detection
Station, it is next to treat that whole pin electric capacity (3) is admitted to whole pin station.
Image collecting device (10) collection is carried out positioned at the capacitor pin image of vision-based detection station to capacitor pin image
Handle to judge whether whole pin electric capacity is certified products.If being judged as certified products, air compressor (16) work, the second gas blow pipe
(25) blow, under baffle effect, qualified electric capacity drops down onto certified products conveyer belt (14).If being judged as non-certified products, scratch diskette (6)
Rotate, electric capacity goes to next station, that is, reclaim station, air compressor (16) work, the 3rd gas blow pipe (25) air blowing, in baffle plate
Under effect, non-qualified electric capacity drops down onto non-certified products recovery band (9) and reclaimed.
Judge that whether whole pin electric capacity is that certified products can automatically be carried out by computer program, is entered according to capacitor pin image
One step includes step：
(1) image preprocessing：
When obtaining image, due to the influence of the factors such as camera subject, light source, gathering image possibly electric capacity can not be presented completely and draw
The full detail of pin, it is therefore desirable to carry out image preprocessing to improve picture quality.Image preprocessing of the present invention mainly includes figure
As smooth and image sharpening.When it is implemented, image smoothing uses median filter effectively to suppress noise, its general principle is
The pixel value that certain in image is put is replaced with the Mesophyticum of all neighborhood point pixel values of the point, so as to eliminate isolated noise spot.By
Image boundary and soft edge are often led in image smoothing, to reduce such adverse effect, so also being used during specific implementation
Sobel differential operators carry out figure sharpening, effectively to strengthen edge or Gray Level Jump part, are apparent from image.
(2) ROI is selected：
Rectangle area-of-interest (ROI, region of interest) is used in specific implementation, ROI region is manually selected,
And ROI subgraphs are extracted from image after pretreatment, handle the object with analyzing as successive image.Extracting ROI subgraphs can
Avoid to the futile searches of non-detection target area and interference in entire image, so as to improve image detection efficiency and computing essence
Degree.
(3) Threshold segmentation：
Pixel value based on original image enters row threshold division to ROI subgraphs, quickly and efficiently to separate capacitor pin
End face and background.Initial threshold T using the gray average of ROI subgraphs as Threshold segmentationi, then adjusted according to following steps
Threshold value, until meeting given criterion.
(a) present threshold value T is utilizediROI subgraphs are divided into region R1And R2, difference zoning R1And R2Gray scale it is equal
Value μ1With μ2：
Wherein, i represents grey scale pixel value, niRepresent the number of pixels that gray value is i.
(b) threshold value is adjusted according to formula (3)：
(c) with threshold value Ti+1For present threshold value, repeat step (a) and (b), until Ti+1-Ti<ε, ε are given convergency value, are led to
Often take 0.02~0.05.
(4) mathematical morphology is operated：
Because capacitor pin end face is not substantially flat, after Threshold segmentation image exist some isolated spotted noises and
Small cavity in connected region, adds the difficulty of follow-up pin end face parameter measurement.Therefore, the present invention opens fortune using morphology
Calculate with the border of smoothing capacity pin end face, while original shape of holding capacitor pin end face.Wherein, morphology opening operation is adopted
The two grown form student movements expanded afterwards with first corroding calculate to complete.
(5) it is qualified to judge whether：
Image after being operated based on mathematical morphology, measurement capacitor pin face area and two pins end face barycenter spacing
From being compared with default capacitor pin standard index, if distance between capacitor pin face area and two pins end face barycenter
Each fall within the range of capacitor pin standard index, be then certified products；Otherwise, it is unqualified.
The embodiment of the simply invention described above, the example above illustrates that the substantive content not to the present invention is constituted
Limitation, person of an ordinary skill in the technical field can repair after this specification has been read to above-mentioned embodiment
Change or deform, without departing from the spirit and scope of the invention.
