ROS Deep Learning CSI Camera parameters


I download ROS Deep Learning package for jetson nano and tried camera source.
But this node starts camera with mode 5 (720*1280) and this mode take image with narrow angle.
camera can not see a large angle which I need. so I need to start camera with mode 1 or 2 and take image with resolution 720*1280 with 21 fps.

For example: in opencv I can start camera object with these settings and capture image.
But i could not manage it in ros deep learning by changing parameters.
How can I do this?


Hi @muhammedsezer12, I don’t explicitly set the sensor-mode in nvarguscamerasrc element from GStreamer, instead I allow it to select the best mode based on the requested resolution.

Have you tried setting the width and height parameters to the video_source node so that it selects your desired sensor mode?

Alternatively, you can modify the GStreamer pipeline used in jetson-inference/utils/camera/gstCamera.cpp:144 to explicitly set your desired sensor-mode :

If you change the C++ code, re-run make and sudo make install after in jetson-inference/build
