Abstract
The invention belongs to digital image processing and relates to a ring positioning tool for detecting a defect image of a sealing ring. The tool is a screen display tool and comprises a ring consisting of two concentric circles, wherein the ring is equally divided into multiple small fan-shaped areas by multiple straight lines; extension lines of the straight lines penetrate through the center of a circle; the position of the ring of the tool can be changed under dragging of a mouse; icons which can change the sizes of corresponding circles under dragging of the mouse are respectively arranged on the circumference of a larger circle and on the circumference of a smaller circle or nearby the circles; the number of the small fan-shaped areas can be changed; when the number of the divided fan-shaped areas is larger, the detection accuracy is higher; when the sealing ring on the image is positioned, the sizes of the larger circle and the smaller circle of the ring are changed through the mouse operation to just cover the position of the sealing ring. According to the tool, the sealing ring is positioned, and whether a defect exists on the sealing ring can be rapidly and accurately detected in an assisted mode.
Description
Affiliated technical field
The invention belongs to Digital Image Processing, relate to a kind of screen instrument for O-ring seal defects detection.
Background technology
Bottle cap is in injection moulding process, and because injection machine injection moulding is bad, O-ring seal (bottle cap inner circle) can deform, expect more and the defect such as few material.In order to coordinate the automatic detection of production line and to reject defective products, need a kind of method that can detect rapidly and accurately O-ring seal defect.
Summary of the invention
The object of this invention is to provide and a kind ofly contribute in image location, O-ring seal position, can assist and detect rapidly and accurately the screen instrument whether O-ring seal exists defect.Technical scheme of the present invention is as follows:
A kind of annulus orientation tool detecting for O-ring seal defect image, this instrument is a screen display instrument, comprise the annulus being formed by two concentric circless, annulus is divided into several little sector regions by some straight lines, the extended line of these straight lines is crossed the center of circle, the position of the annulus of this instrument can change under the dragging of mouse, on great circle circumference and roundlet circumference or near be respectively provided with a big or small icon that can change corresponding circle under for the dragging at mouse; The number of little sector region can change, division more, and accuracy of detection is higher, during O-ring seal location on carrying out image, by mouse action, changes the great circle of annulus and the size of roundlet to the position that can just cover O-ring seal.
Under the cooperation of orientation tool of the present invention, can detect rapidly and accurately injection moulding bottle cap O-ring seal distortion, expect and the defect such as few material more, be no more than 0.4ms detection time.
Accompanying drawing explanation

Fig. 2 annulus orientation tool;
Fig. 3 annulus orientation tool positioning seal ring position;
Fig. 4 testing result.
Fig. 5 (a) is near the shape that when mouse is moved to the circumference of annulus orientation tool, cursor becomes;
Fig. 5 (b) is near the shape that mouse becomes while moving to the little square icon arranging on the great circle of annulus orientation tool or roundlet circumference right side.
Embodiment
Below in conjunction with drawings and Examples, screen instrument of the present invention and application scenarios thereof are described.
The annulus orientation tool of the present invention's exploitation, as shown in Figure 2.The annulus that annulus orientation tool is comprised of two concentric circless and annulus is divided into several little fan-shaped some rectilinear(-al)s, the extended line of these straight lines is crossed the center of circle.This tool location and size can change arbitrarily.
(2) while mouse being moved near the great circle of annulus orientation tool in Fig. 2 or the circumference of roundlet, cursor can become the shape of Fig. 5 (a), now, can press left mouse button and drag the position that changes annulus orientation tool simultaneously left, the home position of annulus orientation tool and the home position of bottle cap are approached as far as possible, as shown in Figure 3; Mouse is moved to the little square on great circle circumference right side of annulus orientation tool in Fig. 2 when mobile, cursor becomes the shape of Fig. 5 (b), now, can press left mouse button and drag to the right and make great circle become large, as shown in Figure 3 simultaneously; While mouse being moved near the little square on roundlet circumference right side of annulus orientation tool in Fig. 2, cursor becomes the shape of Fig. 5 (b), and now, user can press left mouse button and drag left roundlet is diminished simultaneously, as shown in Figure 3.Automatically before detecting, need to gather the image that a width comprises O-ring seal, and show on screen, annulus orientation tool is dragged to O-ring seal position, adjust the size of two circles, make annulus as far as possible just cover whole O-ring seal.According to the position of determined annulus orientation tool and size, calculate the interior all pixel coordinates of whole circle ring area and exist in an array A.At this moment, the order of pixel coordinate storage is according to sequential storage from left to right, from top to bottom, is not to take little sector region to store as boundary.Need to, according to the position of each little sector region, be there is respectively to corresponding array B in the pixel coordinate in A
iin, there are how many little fan-shaped a plurality of arrays that just have.When automatically detecting, identical with the shooting condition before detecting, make the position of the O-ring seal in every width image basically identical.
(3) while automatically detecting, the image of the O-ring seal that each width is collected, wherein the position of O-ring seal is consistent with size with timing signal above.
(4) by array B in step (3)
imiddle pixel coordinate takes out, and asks B
iin the mean value of gray-scale value of all pixels, the average gray of image in little sector region.
(5) by the average gray of image in more current little sector region and the average gray of a upper little sector region and the interior image of next little sector region, obtain the difference of the average gray in two regions, in the average gray of little sector region as corresponding in position that in Fig. 4, the little trapezoid area of grey is identified and around little sector region, the average gray difference of image has surpassed 3, thinks that O-ring seal exists defect.
Claims (1)
1. the annulus orientation tool detecting for O-ring seal defect image, this instrument is a screen display instrument, comprise the annulus being formed by two concentric circless, annulus is divided into several little sector regions by some straight lines, the extended line of these straight lines is crossed the center of circle, the position of the annulus of this instrument can change under the dragging of mouse, on great circle circumference and roundlet circumference or near be respectively provided with a big or small icon that can change corresponding circle under for the dragging at mouse; The number of little sector region can change, division more, and accuracy of detection is higher, during O-ring seal location on carrying out image, by mouse action, changes the great circle of annulus and the size of roundlet to the position that can just cover O-ring seal.
