Possible to calibrate D435 from Ubuntu 18.04?

[JoshDavisNC]

I have an Intel RealSense D435 connected via USB to an Intel NUC running Ubuntu 18.04.

I tried to follow the instructions in this guide to install and run the calibration program. Section 3 says the installation is for Ubuntu 16.04 and 18.04, but the instructions only say to add the xenial repository. The bionic repository doesn't contain the librscalibrationtool or librscalibrationapi packages.

I followed the instructions anyway, added the xenial repository, and tried to install the packages. librscalibrationtool successfully installed, but I could not install librscalibrationapi on 18.04 because of library incompatibilites.

I ran the calibration tool and got through the first two steps before it said "calibration failed". It had apparently written something to the camera, though, because the depth map was very noisy and distorted.

A factory reset fixed that, and now I'm just using the default calibration, which seems to be OK.

Is there a librscalibrationtool package for 18.04, or can I compile it from source? I didn't find it on the RealSense GitHub.

Librscalibrationapi is an optional tool for developers who want to develop their own custom version of the calibration program. If you only need to perform calibration, using just ​librscalibrationtool should be fine.

In the RealSense Viewer program, a lightweight calibration can now be done from the More icon at the top of the options side panel. The icon is the one that looks like a pile of plates.

The Bionic repository address is:

sudo add-apt-repository "deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo bionic main" -u

​If you continue to have difficulties with an Ubuntu 18.04 installation of the calibrator, I recommend posting a question at the GitHub using the New Issue button at the link below, as the staff there are more knowledgeable about Ubuntu (I am a Windows specialist). Good luck.
