I am trying to connect a Flir AX8 camera through python. This camera is connected to the ethernet port of the laptop. So, the VideoCapture()
isn’t recognising the port, I’ve tried all indexes for it (0, 1, 2), but it doesn’t connect. Can anyone help me that how can i connect the camera to python?
I have tried connecting through VideoCapture(1)
and through VideoCapture('IP address')
Using the IP address:
import cv2, time video=cv2.VideoCapture('http://admin:admin@IP address/') a=0 while True: a=a+1 check, frame = video.read() print(check) print(frame) #gray=cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) cv2.imshow("Capturing",frame) key=cv2.waitKey(1) if key== ord('q'): break print(a) video.release() cv2.destroyAllWindows
Using the index 0, 1, 2:
import cv2, time video=cv2.VideoCapture(1) a=0 while True: a=a+1 check, frame = video.read() print(check) print(frame) #gray=cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) cv2.imshow("Capturing",frame) key=cv2.waitKey(1) if key== ord('q'): break print(a) video.release() cv2.destroyAllWindows
I am getting following error in both situations:
False None Traceback (most recent call last): File "C:UsersyashwDesktopex.py", line 15, in <module> cv2.imshow("Capturing",frame) cv2.error: OpenCV(4.1.0) C:projectsopencv-pythonopencvmoduleshighguisrcwindow.cpp:352: error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'cv::imshow'

import cv2 import numpy as np
while True: cap=cv2.VideoCapture(‘http://admin:admin@169.254.253.219/snapshot.jpg?user=admin&pwd=admin&strm=0‘) ret,img=cap.read() cv2.imshow(‘videos output’,img) k=cv2.waitKey(1) if k==ord(‘q’): break
cap.release() cv2.destroyAllWindows
