When designing an image processing system, the choice of the right illumination is often underestimated. The contribution of illumination to image quality is just as important as the choice of sensor, camera and optics. The fact that this choice is not necessarily easy is due to the enormous differences in the objects to be inspected which can be encountered in the context of industrial image processing and automation.
The subject should be regarded similarly as in photography. The photographer sets the decisive accents only through the right lighting to obtain a meaningful picture.
The same applies to industrial image processing. Only that not the eye, but a camera, which can only evaluate grey scales, looks at the image. This makes it even more complex.
Since planistar originally started in the field of photography (production of light boxes), this experience helps us in consultation for the tasks of industrial image processing.
