Hi!
I am using the calibration module to calibrate my DVXplorer-S on Ubuntu 20.04.
When I finish the calibration process, I obtain a calibrated XML file through the calibration module. However, when I try to use the calibrated XML file on the undistort module, I encounter the error 'Impossible to load the camera calibration file: /home/xwh/1.xml'.'undistort moduleInit(): 'std::runtime_error :: Could not load calibration data.', disabling module.'

Hello,
it looks like you performed the calibration locally on your host computer.
To then have the calibration module find the file on the device to run the undistort module on the device itself, you'll have to upload it via SFTP.
Similar to this:
but the file name would be something like /var/lib/dv-runtime/calibration.xml

Hope this helps, have a nice week!
