Abstract:
For calibration on a single camera or a stereo camera, a calibration range is set in advance in an image coordinate system and the calibration is performed in an arbitrary range. A visual sensor controller is a calibration device that associates a robot coordinate system at a robot and an image coordinate system at a camera by placing a target mark at the robot, moving the robot, and detecting the target mark at multiple points in a view of the camera. The calibration device comprises: an image range setting unit that sets an image range in the image coordinate system at the camera; and a calibration range measurement unit that measures an operation range for the robot corresponding to the image range before implementation of calibration by moving the robot and detecting the target mark.

Claim (Index 11):
A non-transitory computer-readable medium encoded with a program for causing a computer to execute the following steps, the computer controlling a calibration device that associates a robot coordinate system at a robot, position information in an image coordinate system at a first camera of a stereo camera, and position information in an image coordinate system at a second camera of the stereo camera by placing a target mark at the robot, controlling the robot so as to move the target mark, and detecting the target mark at multiple points in a view of the stereo camera including at least the first camera and the second camera, the steps comprising:\n a first image range setting step of setting a first image range in the image coordinate system at the first camera; a second image range setting step of setting a second image range in the image coordinate system at the second camera; a first calibration range measurement step of measuring a first calibration range as a first operation range for the robot corresponding to the first image range before the first camera and the second camera are calibrated by controlling the robot to move the target mark and detecting the target mark by using the first camera; and a second calibration range measurement step of measuring a second calibration range as a second operation range for the robot corresponding to the second image range before the first camera and the second camera are calibrated by controlling the robot to move the target mark and detecting the target mark by using the second camera, wherein while the first camera and the second camera are calibrated, the robot is controlled so as to move the target mark in at least one of the first calibration range and the second calibration range, or in a range covered by both the first calibration range and the second calibration range.
