Python OpenCV: Capture Video from Camera
Python provides various libraries for image and video processing. One of them is OpenCV. OpenCV is a vast library that helps in providing various functions for image and video operations. With OpenCV, we can capture a video from the camera. It lets you create a video capture object which is helpful to capture videos through webcam and then you may perform desired operations on that video.
Steps to capture a video:
- Use
cv2.VideoCapture(
) to get a video capture object for the camera.
- Set up an infinite while loop and use the
read()
method to read the frames using the above created object.
- Use
cv2.imshow()
method to show the frames in the video.
- Breaks the loop when the user clicks a specific key.
Below is the implementation.
import cv2
vid = cv2.VideoCapture( 0 )
while ( True ):
ret, frame = vid.read()
cv2.imshow( 'frame' , frame)
if cv2.waitKey( 1 ) & 0xFF = = ord ( 'q' ):
break
vid.release()
cv2.destroyAllWindows()
