| 中文摘要 |
| 构建了由线结构光测头和机器人组成的视觉测量系统. 利用齐次坐标变换的方法建立了测量系统的数学模型. 针对数学模型中的手眼关系, 使用半径已知的球体, 采用定点变位姿的方法, 进行粗略的估计. 考虑到机器人的绝对精度较低, 将定点信息和尺度信息作为优化条件, 对计算机器人的运动学参数和手眼关系做进一步寻优. 实验表明文中的方法能够有效提高测量机器人的重复精度. |
| 英文摘要 |
| A platform composed of a line-structured-light vision scanner and an industrial robot is established for 3D surface digitalization. A mathematical model for the measuring system is constructed by using the homogenous coordinate transform principle and a solution to hand-eye matrix is proposed through measuring a fixed point at different robot hand postures. Considering the absolute accuracy of the robot, a scheme involving scale information and fixed point information is proposed to estimate the robot kinematic parameter errors and hand-eye errors. Test results of real experiments on an industrial robot are reported and analyzed. |
