摘要

In Japan, the economic growth of industries is supported by skillful workers. They have laid the foundations for the present prosperity of Japan. However, they are now at the retirement age. We are afraid that the un-imitable skills and technology become extinct. To solve this problem, Japanese government and companies are trying to apply IT and AI to digitize such skills and make a database of explicit knowledge. In this paper, we explain the developed method to decide the quality of repair of dents in a car by using image processing technology since are industry is supported by skilled workers, but now they are starting to retire. We defined three criteria, such as natural blur of the edge between putty and paint, uniform reflection, clearness of feather edge to decide the quality of repair as follows and evaluated the effectiveness of these criteria. As a result, we found that our method can evaluate the difference of the repaired surface by a veteran and a freshman.
