Abstract
The invention discloses a kind of optical detection apparatus that solve because of the method for the aeration detection in transparent material, comprise the following steps：S1, measured object particle clearly image is obtained, and bubble clearly image；S2, by the way that to the particle, clearly image does image procossing, obtain the abnormal position of particle；S3, by the way that to the bubble, clearly image does image procossing, obtain bubble position；S4, the contrast by the abnormal position of the particle and the bubble position, determine the abnormal position of the particle whether the bubble position scope.The present invention detects out-of-the way position using a sub-picture, and another width image detection goes out bubble position, solves the problems, such as that whether a sub-picture can detect exception but cannot be distinguished by being aeration.
Description
Technical field
The quality testing during transparent materials such as glass, OLED is crimped onto the present invention relates to IC, FPC etc., more specifically
Ground is said, is to solve influence of the bubble to detecting after crimping.
Background technology
IC, FPC (FPC, COF) etc. need to be crimped onto on the transparent materials such as glass, OLED, are detection crimping feelings
Condition is, it is necessary to the crimping picture of other side of being taken pictures through transparent material using optical detection apparatus, but foreign matter, scuffing, crimping material
Defect and transparent material bubble can all be impacted material to image in itself, in addition sometimes influence be very close to, inspection software is very
It is aeration which hardly possible distinguishes, and this directly affects the next step treatment to the problem.
The existing demand for needing to detect bubble position unprecedented in the art.
The content of the invention
The present invention solves the problems, such as that optical detection apparatus influence detection because there is bubble in transparent material, by bubble
Determination, facilitate the producer according to circumstances determine next step operate.
In order to achieve the above object, the present invention provides a kind of solution optical detection apparatus because of the aeration in transparent material
The method of detection, comprises the following steps：
S1, measured object particle clearly image is obtained, and bubble clearly image；
S2, by the way that to the particle, clearly image does image procossing, obtain the abnormal position of particle；
S3, by the way that to the bubble, clearly image does image procossing, obtain bubble position；
S4, the contrast by the abnormal position of the particle and the bubble position, determine the abnormal position of the particle
Whether in the range of the bubble position.
Wherein, measured object is：After IC, FPC (FPC, COF) etc. are crimped onto on the transparent materials such as glass, OLED
Product.Step S4 determine after the abnormal position of particle, so as to judge abnormal whether caused by bubble, or such as foreign matter, scuffing its
He causes factor.
Additionally, in step S1, two images, i.e., acquisition picture of directly taking pictures, specific side can be obtained by two cameras
Method, can be by focusing, and one makes particle clear, and another makes bubble clear.Therefore, the present invention can also be by one
Camera obtains above-mentioned two images.
Additionally, step S2 and S3 are respectively according to particle and the characteristic of bubble, by image processing method such as sciagraphy, difference shadow
Method, template matches, blob analytic approach, obtain the abnormal position of the particle and the bubble position.
Advantage of the present invention：Out-of-the way position is detected using a sub-picture, another width image detection goes out bubble position, solved
A sub-picture of having determined can detect exception but cannot be distinguished by whether be aeration problem.
Brief description of the drawings
Fig. 1 is the particle picture rich in detail of acquisition in a detection embodiment.
Fig. 2 is the bubble picture rich in detail of acquisition in detection embodiment shown in Fig. 1.
Specific embodiment
Process of the invention is to gather two images first, is detected respectively.One sub-picture detects particle out-of-the way position,
Another width image detection goes out bubble position.It is different with detection speed according to cost, in the following manner can be taken：
Mode 1. is gathered twice using a set of acquisition system to examined object, and the image A for once gathering makes to focus on
Particle is clear, and another time the image B of collection is clear to focus on bubble.
Mode 2. shares a set of camera lens and illuminator and IMAQ, one is carried out to examined object using two cameras
The image A of camera collection makes particle clear to focus on, and the image B of another camera collection is clear to focus on bubble.
Mode 3. carries out IMAQ, the image A of a set of collection to examined object at twice using two sets of acquisition systems
Make particle clear to focus on, the image B of another set of collection is clear to focus on bubble.Other modes are not enumerated.
After collecting two images, can be using the one kind in the modes such as sciagraphy, difference shadow method, template matches, blob analyses
Or it is various A images are detected, detect abnormal position, it is similar to use sciagraphy, difference shadow method, template matches, blob
The one or more pair of B image in mode such as analysis detect, detects position and the size of bubble, by calculating, according to
Whether whether particle out-of-the way position judges the abnormal because what bubble was caused of A images in the range of bubble, rather than foreign matter,
What the other factors such as scuffing were caused.
As needed, can be used acquisition system or a camera collection of more sets multiple, improve and differentiate other influences to A
The ability of the object (including and be not limited to foreign matter, scuffing, convex-concave etc.) of image.
Particle as shown in Figure 1 clearly the first comparison diagram, circle is out-of-the way position in figure.Bubble as shown in Figure 2 is clearly
Second comparison diagram, circle is bubble position in figure.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any one skilled in the art in the technical scope of present disclosure, technology according to the present invention scheme and its
Inventive concept is subject to equivalent or change, should all be included within the scope of the present invention.
