imu-cam-calibration crash

[Giovanni Trevisanuto]

Hi!

I am trying to use the dv-imu-cam-calibration module on a Ubuntu 20.04 VM to calibrate my DAVIS346.

One first issue is that it appears to not match the description provided in the README and in this tutorial (see attached image).

If I then try to run the block, it results in a crash with error message  com.inivation.dv.data.Parser Error while reading IOHeader

I'm using a input file block as input. 

Could that be the issue? Or maybe the fact that I'm working on a VM?

If anyone could help me figure this out it would be great.

Thanks,

Giovanni

Hi Giovanni,

The reason the module looks different in the tutorial is that the second camera input was disabled there. It doesn't change anything and the module you are showing can be used for both single camera input or double camera input.

Regarding the crash, since it seems to be a header parsing issue, it seems very likely to come from the file you are using.

Can you let us know how it was generated? What data are you using? Can you show the structure before the crash?

Sorry for the late reply.

Best Regards,
