Oak-D camera Docker container

juancarlostiquerangel

Hello everyone I have the Oak-D camera running in a Jetson nano. I want to use the camera in a docker container in the Jetson nano. The problem is after running the container from the examples here Colorcamera/rgb_preview.py I got some errors with qt. The same error happened when I was trying to use the docker dustynv/ros:foxy-ros-base-l4t-r35.4.1. I tried a lot of ways thinking that it is opencv but nothing is working. Does anyone know what to do ? or maybe how to do it ?

This is the output:

qt.qpa.xcb: could not connect to display

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/usr/local/lib/python3.9/site-packages/cv2/qt/plugins" even though it was found.

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Hi juancarlostiquerangel
Did you run the dependencies script. If so, did it run successfully?

Thanks,
Jaka

Hi jakaskerl

When you mean the dependencies you mean the python file named install_requirements.py ? If so, I just got the next error

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

rosinstall-generator 0.1.23 requires catkin_pkg>=0.1.28, which is not installed.

rosinstall-generator 0.1.23 requires rosdistro>=0.7.3, which is not installed.

rosinstall-generator 0.1.23 requires rospkg, which is not installed.

But I think is because it need ros 1 and I am using ros 2. Now, if you refer to the command sudo wget -qO- https://docs.luxonis.com/install_dependencies.sh | bash that installation was fine.
