Get usb camera id with open cv2 on windows 10
To get the USB camera ID using OpenCV on Windows 10, you can utilize the cv2.VideoCapture
function along with the enumerate_devices
method from the cv2.dnn
module. Here's an example:
pythonimport cv2
# Get the list of available devices
devices = cv2.dnn.enumerate_devices()
# Iterate over the devices and find the USB camera ID
usb_camera_id = None
for device in devices:
if device[1] == 'platform: DirectShow':
usb_camera_id = device[0]
break
if usb_camera_id is not None:
print("USB Camera ID:", usb_camera_id)
else:
print("No USB camera found.")
In the example, we first call the cv2.dnn.enumerate_devices()
function to get a list of available devices. Then, we iterate over the devices and check if the device is a USB camera by comparing the platform with 'platform: DirectShow'
. If a USB camera is found, we store its ID in the usb_camera_id
variable.
Finally, we print the USB camera ID if it was found, or display a message indicating that no USB camera was found.
Please note that the availability and format of the device information may vary depending on the version of OpenCV and the specific camera drivers installed on your system. Adjust the code as needed to match your environment and ensure that the OpenCV package is properly installed (pip install opencv-python
).
