Basler / Camera List

The list system is based on the Pypylon Wrapper. The class:CameraList class is included in the camera_list.py <. It contains methods to create and to display a list of available Basler cameras.

Warning

The camera_list.py must be in the same directory as the Python file containing your script.

Import the CameraList class

To access CameraList class and its functions, import the class in your Python code like this:

from camera_list import CameraList

Example of use

Create a CameraList object

Cameras list is given by an instance of the CameraList class. First of all, you need to create an instance of this class like this:

cam_list = CameraList()

Create a string list of the cameras

The get_cam_list() method from the CameraList class returns a list of a Python tuple of 3 values per camera corresponding to :

index of the camera (integer)
serial number of the camera (string)
name of the camera (string)

You can use this method like this:

cameras_list = cam_list.get_cam_list()

By printing the result of this method, you will obtain something like this:

>>> print(cameras_list)
[[0, 40282239, 'a2A1920-160ucBAS']]

Get a device

You can then access to one of the connected devices by using the get_cam_device() method like this:

cam_id = 0
my_cam_dev = cam_list.get_cam_device(cam_id)

The cam_id corresponding to the index of the camera in the list created previously.

Complete example

from camera_list import CameraList

cam_list = CameraList()
cameras_list = cam_list.get_cam_list()

# Display the list
for cam in cameras_list:
    print(f'ID:{cam[0]} - Name: {cam[2]} - Serial: {cam[1]}')

# Ask the user to enter an index of cameras
cam_id = 'a'
while cam_id.isdigit() is False:
    cam_id = input('Enter the ID of the camera to connect :')
cam_id = int(cam_id)

# Get the selected camera device
my_cam_dev = cam_list.get_cam_device(cam_id)

In this example, a CameraList instance is created. The list of available cameras is displayed in the console. User must enter a valid number. Finally, a camera device is created in the my_cam_dev variable.
