Hello,

Is there any way to access the calibration matrix between IMU and lidar from livox sdk or driver? And is there any way to know that the calibration is disturbed?

Thank you

@Livox-SDK could you comment please where lidar to built-in IMU extrinsics are usually obtained from?

I use mid 360 and information UDP packets do not contain such extrinsics. No information in User Manual too. Livox Viewer 2 also lacks extrinsics.

Looks that at least raw extrinsics should be in access somewhere.

@Livox-SDK Is it still the case that lidar to IMU extrinsics are not publicly available?

I believe an adjacent file https://github.com/Livox-SDK/LIO-Livox/blob/master/launch/mid360.launch should give a good estimate
