FPS is only 3.7 when using opencv to record images


I am using opencv to record images, but the fps is only 3.7. How can I make the fps around 20 ~ 30?



Sorry, the resolution is 1080, framerate is 30 frames/s.

# Create a InitParameters object and set configuration parameters
init_params = sl.InitParameters()
init_params.camera_resolution = sl.RESOLUTION.HD1080  # Use HD1080 video mode
init_params.camera_fps = 30 # Set fps at 30


HD1080@30 FPS is a very heavy configuration for the Jetson Nano.
Have you tested with ZED Depth Viewer for the highest performances that you can reach?
