此函数用于获取输入点相对于指定车道中心线的[s, t]坐标值对

This function is used to obtain the [s, t] coordinate pair of the input point relative to the centerline of the specified lane.

参数:

• id -- [in]

  输入的车道ID，格式为roadId_sectionIndex_laneId

  Input lane ID, formatted as roadId_sectionIndex_laneId.

• pos -- [in]

  输入的3D位置

  Input 3D location.

• s, t -- [out]

  输入点在s-t坐标系统中相对于指定车道的值对
