Access Camera Using OpenCV with Python¶
- first, we Import libraries OpenCV.
- Then we use VideoCapture(0) function to capture the feed of the webcam, here 0 indicates the default value of webcam. If you have secondary webcam use 1 instead of 0
- Now read the frame of the camera frame by frame
- ret is a boolean variable that checks if the camera is on or not
- the frame is a variable in which all the camera feed is being saved
In [2]:
import cv2
capture=cv2.VideoCapture(0)
while True:
ret,frame=capture.read()
cv2.imshow('Color',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
capture.release()
cv2.destroyAllWindows()
Save Image from Webcam¶
In [3]:
import cv2
capture=cv2.VideoCapture(0)
while True:
ret,frame=capture.read()
cv2.imshow('Color',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
cv2.imwrite("MachineLearning.jpg",frame)
break
capture.release()
cv2.destroyAllWindows()
