Top and side inspection with one camera Part 2
When I tried with a nut, the side of the nut was a little dark and the field of view was small when the work distance was about 5mm. I tried to get even closer and got a rather good image. However, if the work distance is negative [...].
Top and side inspection with one camera Part 1
We are experimenting with 360° special optics lenses. It would be best if we could inspect all sides of the workpiece at once with a single camera imaging. We have been working with Edmund Optex and Opt-En [...].

For tests other than comparative inspections
If you are producing the same product in large quantities and the shape of the product is always stable, comparative inspection is the best inspection method. Therefore, we do not explain inspection methods other than comparative inspection when we first make a proposal. However, if the material or the process is not stable and the finished product is [...]...
[Introduction to Image Processing for Machine Vision and Image Inspection 2017] Released
It was released on April 10, 2017, and I had the pleasure of writing the preface to this issue. I am pleased to share with you the need to put aside the technical details of image processing technology and put it to work in the field on a day-to-day basis.
Sales of single software products
Currently, we (basically) do not sell the software as a stand-alone product. When the Windows operating system is upgraded, we will be able to support new projects so that FIS-100 will work. Now [...].
FIS-100 AND LED POINT LIGHT SOURCE
OUR SOFTWARE FIS-100 WILL TEST IF IT IS THE SAME AS USUAL. HOWEVER, IT IS NOT PATTERN MATCHING. SINCE THE IMAGES DO NOT ALWAYS LOOK 100% THE SAME, WE USE STATISTICAL METHODS TO CHECK IF THE IMAGES ARE ALMOST THE SAME AS USUAL, ALLOWING FOR VARIATIONS [...].
IT'S NOT ENOUGH TO BE ABLE TO SEE THE NG PART.
SINCE VISUAL INSPECTIONS ARE CONDUCTED TO PREVENT THE OUTFLOW OF NG PRODUCTS, IT IS ONLY NATURAL TO MAKE SURE THAT NG PARTS ARE CLEARLY VISIBLE TO THE CAMERA. HOWEVER, IF THE CAMERA ALSO CLEARLY SHOWS OK PARTS OTHER THAN NG PARTS, IT WILL BE DIFFICULT TO DRAW A LINE BETWEEN OK AND NG PARTS. THEREFORE, IT IS IMPORTANT THAT THE CAMERA'S [...]...
Chip Saw Inspection Demo
We often experiment with chip saws and gears, as these are the most common themes these days. It works well with our versatile software FIS-100 and provides a great return on investment. We have uploaded a video of the demonstration situation on YouTube, so please [...].
Wavelengths of Light, Part 2
In the last issue we discussed lighting in general terms. We have been experimenting with various wavelengths of lighting. In terms of visible light, we have tried red, green, blue, white, etc. We have also tried ultraviolet light, and in terms of visible light, we have tried red, green, blue, white, etc. The conclusion we have reached is that white light is basically the way to go. Of course, it's not as easy as it looks [...].
