输入的数据的坐标系是怎么定义的?
激光雷达坐标系的定义? 上图为我保存的输入到模型的激光点云数据,从点云数据来看,激光雷达的坐标系应该是:x指前,y指左,z指上
target_point坐标系定义? 上图为我保存的输入到模型的target_point的打印,此时车辆在右转,根据打印坐标看,我理解的target_point的坐标系定义是:X指右,y指后,因为车辆在直道上行驶的时候x几乎为零,y是从-50到0递增。
还有计算target_point的时候用到的theta是怎么定义的?和是和那个轴的夹角,逆时针还是顺时针为正?
车身坐标系的定义和target_point一样吗?
以上坐标系的定义看起来和carla里面不一样,我这边查到的carla里面的坐标系定义如下图:
我目前对于代码里坐标系定义这块还不是很清楚,能否明确一下?

你好!
坐标系以代码为准,和carla等无直接联系。问题1和2的理解都是对的。问题3:theta是compass + 1/2 pi, compass的定义来自于carla leaderboard (https://github.com/opendilab/LMDrive/blob/43fc2e9a914623fd6eec954a94aeca2d3966e3db/leaderboard/team_code/lmdriver_agent.py#L353)。问题4:一样的。
Sorry, something went wrong.
