Extrinsic calibration failed #71

Hi,

I was trying out your package with the test data and my own data, and for both cases, the extrinsic always fails to complete the calibration. For my personal data, I know what is the rotation and translation between lidar and IMU, thus I tried to set estimate_extrinsic parameter to 1, but the mapping completely fails in that case. The sample data i tried to use was fast1.bag and fast2.bag. Maybe you have an initial guess why would that be happening?

I have the same problem. Have you solved it?
