about imu params

[dengyinglong]

may I have the params of the imu used in the dataset？such as acc and gyro cov and bias cov.Thanks a lot!

Sorry for the late reply. Since the imu on CF Bolt was not a high-end one, I didn't calibrate it through Allan variance measurements. You can tune the IMU cov and bias cov in the dataset to see if you can get performance improvement. If you find a great param for these param, welcome to submit a PR so that we can incorporate this info! Thanks!
