您好,麻烦您几个问题
1.Online Refinement阶段是继续做旋转激励(在原地像视频中一样旋转),还是做一些平移运动比较好(比如跑一个完整的回环指令)
2.外参数校准结果、特别是平移与设定的Online Refinement有很大关系,比如有时候我优化10s结果很好,而优化30s结果就很差,或者我有其他方法判断外参收敛到准确值吗

online_refinement阶段建议是继续沿三个轴画弧线,保证同时有旋转和平移激励(像视频中一样)。refine阶段实际上运行的是FAST-LIO2,其需要优化的状态量很多,所以不能保证外参标定精度有多高。我的经验和建议是多标定几次,计算几次initialization_result的均值作为最终的外参结果。
