[aiqibaobei]

Hey,thank you for this amazing project.I am trying to deploy this project with Livox Aiva and its internal IMU.At first,I can get good result,but after a while,the odom seems drift too fast.I am quite stange about one thing : with the same param,every time the odom drifts in different postions,which makes me can't tune the param.Is my computer too old ,?It has intel i7-6700HQ,16G RAM,GTX960M. And I hope to get some advices about the key params in the yaml file.
