If there was an imaging test that could be set up in minutes...

Most imaging systems today take several hours or more to set up and start up. For this reason, various efforts are made to ensure that once the data is set up, it can be used for a long period of time and can be reused.
For example, "keep the brightness of the lighting constant" or "use the data from other cameras".
However, when we tested various things with FlexInspector, we found various things.
(1) It is much more difficult to keep lot-to-lot variation constant than to keep lighting brightness constant. Therefore, in order to perform high-precision inspections, fine adjustments are necessary for each lot, and in the short term (i.e., one lot), it is not so important whether the brightness of the illumination is constant or not.
(2) Images captured by other cameras do not exactly match. It is impossible to use them all over the place because of their non-negligible effect when performing high-precision inspections. Even if four images are taken from one field of view, those four images will not be the same due to lens distortion, so it is difficult to use them all.
In the end, it is necessary to "make settings for each lot" in order to perform high-precision inspections. If there was an image inspection that could be set up in a few minutes..." but rather, "if it were not an image inspection that could be done, actual operation would be difficult.
One FI user has achieved good results by re-registering several dozen good products at once at the beginning of a lot, and inspecting the remainder to see if they are finished in the same way as the good products. Here, there is no effect of lot-to-lot variation, and the lighting only needs to be stable for the duration of one lot.
