How can I find the camera's maximum resolution provided by the manufacturer in Python code?

I couldn't find any option provided by OpenCV to get maximum resolution available.

Is there a possibility using any other python package?

In Python, you can use the "cv2.CAP_PROP_FRAME_WIDTH" and "cv2.CAP_PROP_FRAME_HEIGHT" properties of "cv2.VideoCapture" to obtain the maximum resolution supported by the camera. Here's an example code:

import cv2
def get_max_resolution():
    cap = cv2.VideoCapture(0)  # Use the appropriate camera index (0 for the default camera)
    max_width = cap.get(cv2.CAP_PROP_FRAME_WIDTH)
    max_height = cap.get(cv2.CAP_PROP_FRAME_HEIGHT)
    cap.release()
    return int(max_width), int(max_height)
max_width, max_height = get_max_resolution()
print(f"Maximum resolution: {max_width}x{max_height}")

In this code, we open the video capture using "cv2.VideoCapture(0)" where "0" represents the default camera. You can change the index according to your camera setup. Then, we retrieve the maximum supported resolution using "cap.get(cv2.CAP_PROP_FRAME_WIDTH)" and "cap.get(cv2.CAP_PROP_FRAME_HEIGHT)". Finally, we release the video capture and print the maximum resolution. Please note that the maximum resolution reported by the camera may depend on various factors such as camera model, drivers, and system limitations.

  • this is wrong. The above code only gives the actual resolution. I researched a lot and couldnt find any option in opencv package to get max resolution. – van Jul 05 '23 at 09:13
  • That code gives you the maximum resolution supported by the camera you specify. I validated the code. Output was fine – Python-Turtle Jul 05 '23 at 10:08
