Abstract

An industrial robot calibration algorithm is presented, which uses a line-structure-light sensor. In the proposed method, the sensor is attached to the robot's end-effector and the centre of a ball with known radius is regarded as a virtue point and the robot carries the sensor to measure this virtue point. The kinematic parameters of the robot are estimated due to the coordinates of the virtue point is invariable in robot base frame. An example verifies the effectiveness of the proposed method.

基于线结构光视觉传感器的机器人自动标定方法
提出了一种基于线结构光传感器的工业机器人标定算法。在该方法中,传感器附着在机器人的末端执行器上,以已知半径的球的中心为优点点,机器人携带传感器对该优点点进行测量。由于美德点在机器人基架中的坐标不变,对机器人的运动参数进行了估计。算例验证了该方法的有效性。
