Issue Description

<Describe your issue / question / feature request / etc..>
Hi,

I'm sorry to ask about a problem with Kalibr here. I have posted an issue in the Kalibr repository about my problem. I want to calibrate the extrinsic between the camera and IMU. But it seems like the timestamp of IMU causes the kalibr_calibrate_imu_camera of Kalibr crash. How do you calibrate the extrinsic between the camera and IMU? Could you please provide some advice? Thanks a lot!

Hi @TouchDeeper The link below has a Kalibr project that provides an IMU calibration file for D435i.

Hi @MartyG-RealSense
Thank you for your reply, but it seems like he did not have the same problem as me.

Their calibration command follows the same structure as the one that you posted in your Kalibr topic. Does the D435i yaml file provided in that project not assist with your own calibration problem please?
