The invention provides a marking operation calibration method for a bulkhead marking
robot, which comprises the following steps: mounting a
laser tracker on a ship wall to be marked, arranging the
robot on the ship wall to be marked, and mounting a
gyroscope on the
robot; calibrating a conversion relation from a
laser tracker coordinate
system s to a cabin wall coordinate
system b; obtaining a ZYX Euler angle change relation from a cabin wall coordinate
system b to a mechanical arm coordinate system r, and calibrating a zero point of a
gyroscope; measuring the position of the origin of the robot in the cabin wall coordinate system b in real time, and guiding the robot to reach a target
workstation; and in combination with an original point position measured in real time and a zero point of a
gyroscope, a
motion control track of the robot in the working
station under a mechanical arm coordinate system r is solved, and a marking operation calibration task of a
single station is completed. According to the method, the conversion process of
robot planning motion data from drawing stipulation data to site specific application data is combed, and accurate lineation
station guide data and lineation point guide data are provided for wall surface operation of the LNG bulkhead robot.
