Camera position-correcting method and system and dummy component for use in camera position correction

摘要

There are provided a method and device for correcting a camera position, and a dummy component for use in camera position correction. A board-sensing camera for sensing a position of a circuit board is caused to take an image of a dummy component in an attitude-fixed state in a first coordinate system peculiar to a board-sensing camera. A component-sensing camera for sensing a position of an electronic component to be mounted on the circuit board is caused to take an image of the dummy component in an attitude-fixed state in a second coordinate system peculiar to a component-sensing camera. An amount of deviation of a center of the dummy component from a sensing center of the board-sensing camera and an amount of deviation of the center of the dummy component from a sensing center of the component-sensing camera are calculated from results of the taking of the image of the dummy component by the board-sensing camera and results of the taking of the image of the dummy component by the component-sensing camera. At least one of the first coordinate system and the second coordinate system is corrected based on the calculated amounts of deviation of the center of the dummy component.
