Description
Technical field
The present invention relates to a kind of novel tray IC detection means, more particularly to a kind of view-based access control model processes to detect IC surfaces
The whether correct device of character.
Background technology
According to product (IC) measurement requirement, need to carry out check measurement to its face character, direction polarity, spacing etc., belong to
In character recognition, dimensional measurement class visual inspection.Traditional dimensional measurement relies primarily on the survey tools such as employee's slide calliper rule, and must
Must offline after single measurement, not only certainty of measurement is easily affected by human factors, and measuring speed is not high, affect work efficiency；
And the identification of character is judged one by one by human eye, artificial erroneous judgement just can not ensure that.By the detection system of machine vision framework
System, as long as selecting suitable hardware, can carry out the inspection such as high speed dimensional measurement and judgement, character recognition, polarity judging to product
Look into measurement.
The content of the invention
In view of the foregoing defects the prior art has, this application provides a kind of pallet IC detection means, the saving of this device
Manpower, it is ensured that the quality of product.
For achieving the above object, the technical scheme of the application employing is：Pallet IC detection means, specifically includes：Industrial phase

Further, embedded system is housed on the industrial computer.
Further, the industrial camera I, industrial camera II, industrial camera III are vertically arranged with IC placement trays.
Further, the LED light source is relative to IC placement tray slant settings.
The present invention is due to using above technical scheme, obtaining following technique effect：
The application adopts high speed image acquisition board, and the capture card supports multiplex image acquisition, is now carried out using 3 industrial cameras
Shoot simultaneously, then carry out picture splicing, ultimately form the high-resolution picture of large area, sentence Jing after host computer PC process
It is fixed whether normal；
This device saves manpower, it is ensured that the quality of product, further increases detection efficiency.

Specific embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
Embodiment 1
The present embodiment provides a kind of pallet IC detection means, specifically includes：Industrial camera I, industrial camera II, industrial camera
IIIth, LED light source, IC placement trays, industrial computer, image pick-up card, light source controller；The industrial camera I, industrial camera
IIth, industrial camera III is connected with image pick-up card, the industrial computer respectively with image pick-up card, light source controller phase
Even, the light source controller is also connected with LED light source；The industrial camera I, industrial camera II, industrial camera III, LED light source
It is placed in IC placement trays top.
Preferably, embedded system is housed on the industrial computer.
Preferably, the industrial camera I, industrial camera II, industrial camera III are vertically arranged with IC placement trays, described
LED light source is relative to IC placement tray slant settings.
Embodiment 2
The present embodiment provides a kind of pallet IC detection methods based on embodiment 1, specially：Produced using advance Jing self studies
After raw series of standards image is processed with the respective image of collection, the result for detecting and the quality for judging product are obtained.Its
It is seamless spliced that core technology is that the image of 3 industrial cameras collection is carried out, and is divided into three key steps：Image semantic classification, image
Registration, image co-registration and edge smoothing.
Image semantic classification is the suppression etc. that geometric distortion correction and noise spot are carried out to image, allows reference picture and to be spliced
There is no obvious geometric distortion in image；Image mosaic is carried out in the case where picture quality is undesirable, if without image
Pretreatment, it is easy to cause some error hidings.Image semantic classification is mainly prepared for next step image registration, allows picture quality
Disclosure satisfy that the requirement of image registration.
Image registration is that the match information in reference picture and image to be spliced is extracted, in the information for extracting
Optimal matching is found, the alignment between image is completed.The success or not of image mosaic is mainly the registration of image.Figure to be spliced
As between, it is understood that there may be various conversion or large-area homochromy region etc. such as translation, rotation, scaling are difficult situation about matching,
Image registration algorithm can accurately find in all cases the corresponding informance between image, by image alignment.
Image co-registration is to complete after images match, to suture image, and the border to suturing is smoothed,
Allow and suture nature transition.Because any two width adjacent image is impossible to accomplish identical on acquisition condition, therefore, for
Some should identical picture characteristics, the such as light characteristics of image, what is would not showed in two images is just the same.
Image mosaic gap be exactly from the image-region of piece image be transitioned into the image-region of another piece image when, due in image
Some correlation properties there occurs transition and produce.Image co-registration is exactly that splicing is more in order to make the splicing gap between image not clear aobvious
It is natural.
In obtaining the standard picture for having spliced, engineer can define the character on each IC surface during template is set up
Template, and the image and its coordinate of each template are preserved, deposit to data base.During detection product, using being stored in data
Template in storehouse carries out template identification and compares in collection image, it is possible to know how many individual correct IC of whole pallet and mistake
IC by mistake.So far the quality of product is it may determine that and output.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
