| Outline of Final Research Achievements |
This study focuses on differences of inspection environment, and considers experimentally the effect of luminance of an inspection surface, luminance of light on defect detection in visual inspection utilizing peripheral vision. In the experiment, the luminance of an inspection surface, the luminance of light, defect locations, and defect characteristics (luminance contrast and size) are designed as experimental factors, and their effect on defect detection rate is evaluated. As a result, it is clarified that the defect detection rate is different according to the luminance of an inspection surface and light. From the above, in order to realize highly accurate visual inspection, it is necessary to control appropriately inspection environment.
