Document Type and Number:
Japanese Patent JP2022152845
Kind Code:
A
Abstract:
To provide a calibration device for controlling a robot that can teach posture collection of a robot in consideration of shielding of a marker, and reduce man hours required for teaching the posture collection of the robot.SOLUTION: A calibration device 2 includes: an imaging part 32 for executing imaging from the position determined beforehand; a marker 31 attached to a robot 30; a posture collection generation part 23 for generating posture collection including a plurality of postures of the robot 30; a non-shielding posture extraction part 26 for extracting a plurality of postures in which shielding of the marker 31 does not occur from the posture collection; and a calibration execution part 29 for estimating coordinate conversion parameters for converting a coordinate system of the robot and a coordinate system of the imaging part on the basis of the plurality of the extracted postures.SELECTED DRAWING: Figure 1
