Tips for improving result accuracy

Open Mastergalen opened this issue 3 years ago • 1 comments

Hi there,

Thank you for releasing this great tool for calibration.

I was able to record a calibration sequence and run it through the application with not much trouble.

Here are the results I got, however, the extrinsics deviate by about 6mm in the x-translation (forward/backward) from what we would expect from our CAD model.

Are there any tips or gotchas when recording the calibration sequence? I have also also attached the rosbag and the config file we used. Dropbox Link

Thank you in advance.

Hi, thank you for your comments. I want to ask what is the expected translational extrinsic value from your CAD model? If the error is less than 1 or 2 centimeters, I think that would be an acceptable result.
