Inspection accuracy ③.
In the case of a pixel resolution of 30μm (0.03mm), the field of view range can be calculated by applying the following formula. Pixel resolution = horizontal (X)/vertical (Y) field of view ÷ horizontal (X)/vertical (Y) resolution [...].
Inspection Accuracy (2)
As a case study, we will use the Basler acA640-750um (300,000 pixels) camera used for the ping pong system we are promoting. Basler acA640-750um The specifications of this camera [...].
Inspection Accuracy (1)
How large an object can be inspected? How small defects can be detected? We are often asked these questions. To summarize, if you are willing to spend the money and do not mind the inspection time, you can inspect objects of any size [...].
Visual inspection of resin molded products
Today, we brought a demo machine to a plastic molding company. The shape of the product is cylindrical, and the top, bottom, and sides are to be inspected 360 degrees. The main purpose of the visit was to verify that the side of the product could be inspected stably and to get the customer's satisfaction.
Visual inspection of castings
I have been involved in the visual inspection of a wide variety of products, but there are certain types of products that are difficult to inspect. For example, we have not found the best answer to the question of "dents" or "porosities" on castings. The reason is that the surface of the casting is uneven, and the pattern is not consistent [...].
FROM HALCON 6.0
HALCON, the world's best machine vision system construction tool, was developed by MVTec of Germany and is distributed in Japan by Links, Inc. This HALCON continues to evolve and on November 1 (2016), the latest version "13.0" will be released.
Solution 4] Shomei problem
This is a continuation from the previous post. Here is an image obtained by using a 2.5mm small ring illumination (high angle). The angle of incidence is close to 90 degrees of the coaxial illumination, so the image is relatively close to the coaxial illumination. The smooth areas that have been rubbed have turned white [...].
Solution (3)] Shomei problem
This is a continuation of my previous post. The following is the image obtained when coaxial lighting was used. The smooth area is almost a mirror, so the direct light from the coaxial illumination hits the frayed area and is captured by the camera as it is [...].
Solution 2] Shomei problem
This is a continuation of my previous post. What would the image look like if coaxial illumination was used in #1? Coaxial illumination, also called coaxial epi-illumination, is illumination that shines parallel (90 degrees) to the camera. The lens cap rubs against the [...].
Solution (1)] Shomei problem
This is the answer to my last post. The answer is 3. Large ring illumination (low angle placement). The reason why the rubbed area turns black is because the normal surface of the camera lens cap is a little rough [...].
