About the z-axis error

[tazel7885]

I'm testing the package using ouster-64.
The calibration is fine for the x and y axes, but there's still an error of about 5cm in the z-axis.

1. Is there a way to better compensate for the z-axis error?
2. Is there any terrain that's advantageous when collecting data?

I have the same problem. Did you solve it?
