Lidar-Imu Calibration #39

Open Blackshaddock opened 4 years ago

Blackshaddock commented 4 years ago

Hi！I am currently doing Lidar-Imu calibration. Can you tell me how to get the initial external parameters of laser-imu. In addition, i record the still data and used imu-utils to calibrate the noise and bias of the IMU, but the accuracy is especially high, so can you tell me how to calibrate the noise of IMU with dynamic data. Thank you very much!

I hope this link from Kalibr could help you.

Hi! Does the lack of calibration cause loss of orientation ? Regards, Bruno
