自动驾驶云服务 OCTOPUS-Struct:orientation_3d

orientation_3d 定义：由Tait–Bryan角度的三个参数roll（横滚角，围绕x轴的角度）、pitch（俯仰角，围绕y轴的角度）和yaw（偏航角，围绕z轴的角度）定义的三维角度。用途：设置实体的朝向角度、用于构成pose_3d。参数：参数如下表表5 orientation_3d参数 Parameter Type Mandatory Description roll angle yes rotation angle around the x-axis pitch angle yes rotation angle around the y-axis yaw angle yes rotation angle around the z-axis 根据ISO 8855的定义，角度旋转的顺序是：首先进行yaw（围绕z轴）、接着pitch（围绕新y轴），最后roll（围绕新x轴）。当实体的朝向与road0的方向相同时，无需设置orientation_3d。 angle的单位一般为rad（弧度）而非degree（角度），rad = degree*pi/180，1rad约等于57.3度（详见scalar units中的angle units一节）。与road 0的方向相反（相差180°） m_orientation: orientation_3d with: keep(it.roll == 0.0rad) keep(it.pitch == 0.0rad) keep(it.yaw == 3.14rad)
