Lighting conditions

If it is a visual inspection, I think it would be basic to inspect by scattered light.

In which environment would people be interested in the appearance of the building when they see it?

Most of the time, natural light (scattered light) is present.

Naturally, the appearance does not matter in the dark.

IN OTHER WORDS, NG IS NOT VISIBLE.

Considering inspection equipment for three-dimensional objects,

It's a matter of the positioning of that workpiece, the lighting, and the camera.

It is normal for the work to have shadows and dark areas.

It is difficult to inspect in dark areas,

We want to make the area as bright as possible.

The firm often does this in such cases,

Expect the light to go around,

MAKE A BOX WITH WHITE MATERIAL,

The idea is to inspect the workpiece in this context.

LIGHT IS SCATTERED INSIDE THE BOX, MAKING IT EASIER TO INSPECT.
