Abstract

Improvements in image processing have recently resulted in the wide use of inspection systems. The lighting technique in such systems is very important because the quality of the image is determined by the illumination. Furthermore, the quality of the image determines the cost, speed, and stability of the inspection system. It is therefore necessary to consider what kinds of lighting technique are most suitable for each object, but there are a only few studies on lighting technique. The present theoretical study investigated how much difference was obtained by the difference of lighting technique. The brightness or intensity on the surface of a model printed circuit board was calculated by using Monte Carlo method. This study confirmed the effectiveness of supplementary light for inspecting a three-dimensional object.
