在OpenCV中,眼在手外手眼标定是一种通过求解方程AX=BX来确定手眼关系的方法。其中,A是机械臂末端到基点的变换矩阵,可以通过示教器或者在ROS直接订阅相关tf获取;B是标定板到相机的变换矩阵,可以使用pnp算法求解得到。OpenCV提供了一个名为calibrateHandEye的算子来实现手眼标定。该算子的输入参数包括R_gripper2base和t_gripper2base,表示机械臂末端到基点的多个旋转矩阵和平移向量;R_target2cam和t_target2cam,表示标定板到相机的多个旋转矩阵和平移向量。算子的输出参数包括R_cam2gripper和t_cam2gripper,分别代表相机到机械臂末端的旋转矩阵和平移向量。使用该算子可以得到眼在手外的手眼标定结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
