In the related research about the micro-drills image of measurement system, we put most emphasis on the feature extraction and the calculation of the defects. Rare do people deliberate upon the false positive rate seminars caused by men. Therefore, this study focuses on the adjustments of light sources, the binary image settings and the regulations for specifications which require men adjustments. In order to prevent the bias caused by human, we decided to progress and revise these three parts automatically. When testing the micro-drills, the rotating angle isn’t fixed. Under this character, regular measurement systems often use it to match the similarities. Using the similitude to obtain the center of coordinates and the cross angle that parallels to the axis. Whereas, the matching up will result in errors of percentage points while checking on the mass producing. Therefore, this research can replace the algorithm of pattern matching and reduce the error rate of percentage points.
