Taking and saving pictures nvidia nano rpi camera v2

Hello!

I am new to nvidia nano (just got my first nano!)
I for a school project I was trying to use the nvidia nano (with two camera slots) and two RPI cameras V2
I was able to watch the video feed using the jetsonhacks examples. But I cannot find any documentation on how to take and save pictures using both cameras. I know there is some documentation I just cannot find it.

Would anyone be able to help me?

You watched this video clip, aren’t you?

In CSI-camera resources, simply,
add some key-input to save an image
cv2.write(filename, camera_images)
after
cv2.imshow("CSI Cameras", camera_images).

Try that!

hello Edwin_Meriaux,

you may refer to Camera Architecture Stack to have an overview of the NVIDIA camera software architecture.
there’re several documentations for your reference,
for example,

  1. NVIDIA Jetson Linux Developer Guide, sample commands from Approaches for Validating and Testing the V4L2 Driver.
  2. NVIDIA Jetson Linux Developer Guide, Gstreamer user guide.
  3. Jetson Linux Multimedia API Reference, MMAPI sample applications.
