Description

Threaded hole three CCD camera testing agency
Technical field
The present invention relates to a kind of thread quality pick-up unit, particularly relate to a kind of threaded hole three CCD camera testing agency.
Background technology
For the internal thread that vitals is provided with, in installation process, need screw or screw to be screwed into.The recurrent problem in process that is screwed into be because the quality problems of internal thread cause whole internal thread stripped thread or other damage and occur, often due to the damage of an internal thread, scrapping of whole vitals will be caused, lose larger.In order to avoid above-mentioned technical matters, the external thread on internal threads and screw is in advance needed to carry out quality testing.Carry out again being screwed into operation after rejecting defective products.
External thread on screw or screw, owing to being positioned at outside, detects in advance to the screw thread on its surface, rejects defective products and is easy to accomplish.But the detection of internal thread is just not easy to realize, and first internal thread is positioned at hole, not easily observes, particularly the screw thread of the larger position of the degree of depth, be also be difficult to especially detect.
Generally include in the project of quality testing: the internal diameter of internal thread, external diameter, the many threads of internal thread, tooth distance between every two two adjacent rings screw threads, spacing (depth of threat) between first lap screw thread and last lap screw thread, (invalid tooth comprises thread: rotten tooth to also have the effective tooth detecting screw thread, agomphosis and agomphosis, even comprise the existence of foreign matter and burr), full tooth rate can also be calculated by internal diameter outside dimension, full tooth rate: just refer to that thread on internal thread hole is before choosing (doing) silk in advance, the internal diameter in hole is enough little, just the silk of that part of end is sharp entirely for the silk that such material picks out, as be not with that of material will lack that part silk point, the quality do not lacked and lack represents with regard to this full tooth rate.
ROI (region of interest) i.e. area-of-interest.In machine vision, image procossing, sketch the contours of need region to be processed from processed image in modes such as square frame, circle, ellipse, irregular polygons, be called area-of-interest, ROI.The machine vision softwares such as Halcon, OpenCV, Matlab are commonly used various operator (Operator) sum functions to try to achieve region of interest ROI, and carry out next step process of image.In image processing field, area-of-interest (ROI) is the image-region selected from image, and this region is the emphasis that your graphical analysis is paid close attention to.Draw a circle to approve this region to be further processed.Use ROI draws a circle to approve the target that you want to read, and can reduce the processing time, increases precision.
