PURPOSE:To provide a method for detecting the position of an electrode as a recognition object at high speed and with accuracy, regarding image recognition and processing in an electronic part packaging facility or the like. CONSTITUTION:With both lights for transmission and reflection turned on, an electronic part is photographed and an image pattern is obtained at the first process. Then, a boundary between an electronic part pattern in the image pattern and a background is obtained, and the outline of the part is thereby recognized. The rough inclination and center of the part is obtained on the basis of the outline so obtained. A processing area for detecting an electrode is set, according to the rough center and inclination, and the position of the electrode is detected by finding the extreme value of brightness projection data in the processing area. |
