<p><P>PROBLEM TO BE SOLVED: To provide a component orientation determining device which shortens processing time required for determining an orientation of a square-shaped component. <P>SOLUTION: A component orientation determining device determines an orientation of a square-shaped component having a feature point indicating an orientation thereof by means of image processing. The component orientation determining device performs steps of: pre-storing standard data of an aspect ratio of the component in a storage device 14; taking an image of the component from bottom thereof by putting the whole figure thereof into one viewing field of a component-recognizing camera 12, when the component in production is sucked onto a suction nozzle; recognizing periphery of the component based on the taken image to calculate two aspect ratios when the component is viewed from two directions different 90-degree each other; comparing the two calculated values of aspect ratio with the standard data thereof stored in the storage device 14 to select two directional candidates corresponding to two calculated values of aspect ratio with smaller difference; and applying image processing on two of the images of the component, respectively, corresponding to the selected two directional candidates to identify an orientation of the component based on the direction from which the feature is recognized. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
