Retrieve extended camera information in Ubuntu

Marcus · November 10, 2023, 2:25am

Hi there! Is there a way to get extended camera information to find out what specific camera model is used in a certain machine - in my case ZED2i (2.1mm, 4mm, w/ or w/o polarizer)? As far as I can see the commands

hwinfo

and

v4l2-ctl --device=/dev/video0 --all

don’t show this info, right? Any help is appreciated

Hi @Marcus
Welcome to the Stereolabs community.

Unfortunately, it is not possible to retrieve such information with OS commands, ZED SDK API calls are required. You can create a Python script to open all the available connected devices and retrieve the required information.
This example is a good starting point:

github.com

stereolabs/zed-sdk/blob/master/tutorials/tutorial 1 - hello ZED/python/hello_zed.py#L38


      
              # Create a InitParameters object and set configuration parameters
              init_params = sl.InitParameters()
              init_params.sdk_verbose = False
          
              # Open the camera
              err = zed.open(init_params)
              if err != sl.ERROR_CODE.SUCCESS:
                  exit(1)
          
              # Get camera information (ZED serial number)
              zed_serial = zed.get_camera_information().serial_number
              print("Hello! This is my serial number: {0}".format(zed_serial))
          
              # Close the camera
              zed.close()
          
          if __name__ == "__main__":
              main()
