    • The present invention discloses an automatic calibration method for a robot system, comprising steps of: calibrating intrinsic parameters of a sensor and a sensor coordinate system of the sensor with respect to a world coordinate system by means of a calibration plate; and controlling a robot under the guidance of the calibrated sensor to move an original point of a tool coordinate system of a tool mounted on the robot to reach the same target point with a plurality of different poses, and calculating a transfer matrix tcp T t of the tool coordinate system with respect to a tool center point coordinate system of the robot based on pose data of the robot at the same target point. The robot can accurately move to the same target point with the plurality of different poses, improving the calibration accuracy of the robot system. Furthermore, the calibration of the robot system is automatically performed by a control program, increasing the calibration efficiency, and simplifying the calibration operation.
    • 本发明公开了一种机器人系统的自动校准方法,包括以下步骤:通过校准板校准传感器的相对于世界坐标系的传感器和传感器坐标系的固有参数; 并且在校准传感器的引导下控制机器人,以使安装在机器人上的工具的工具坐标系的原点移动到具有多个不同姿势的同一目标点,并计算工具的传递矩阵tcpTt 基于相同目标点的机器人的姿态数据,相对于机器人的工具中心点坐标系的坐标系。 机器人可以用多种不同的姿势精确地移动到同一目标点,提高机器人系统的校准精度。 此外,通过控制程序自动执行机器人系统的校准,提高校准效率,并简化校准操作。
