【摘要】 针对目前机器人手眼标定的方法大多需要求解手眼标定的基本方程,提出了一种新的用于机器人手眼标定中初值估计的方法.该方法在非线性优化过程中需要对初值进行估计,不同的初值可得到不同的结果,传统技术主要通过经验选取初值.本文利用机器人自身的运动模式,直接确定初值,大大减小了经验选择给结果带来的偏差.与经验选择初值的方法进行对比,结果表明,本方法得到了明显的改善.更多还原

【Abstract】 Considering that in most hand-eye calibration methods, the basic equation needs to be solved, a new initial estimates method for robotic hand-eye calibration was proposed. Initial values are needed in optimizing the process of solving the equation, while in existing method, initial values are selected depending on experience. The value is determined directly by considering the robot movement model, which can (effectively) avoid the errors introduced by experience. Compared with classical methods, the proposed method shows a better improvement.更多还原
