I would like to have a "burst" effect and take multiple pictures when the user presses a button once. What I currently have is the picture function in a loop, which requires the user to press a button for every picture, which also closes and reopens the camera feed.
pictures = 4
for i in range(pictures):
camera = cv2.VideoCapture(1) #if there are two cameras, usually this is the front facing one
if camera.read() == (False,None):
camera= cv2.VideoCapture(0)
else:
pass
while True:
return_value,image = camera.read()
gray = cv2.cvtColor(image,cv2.COLOR_BGR2GRAY)
cv2.imshow('image',gray)
if cv2.waitKey(1)& 0xFF == ord('s'): #take a screenshot if 's' is pressed
cv2.imwrite('burst'+str(i)+'.png',image) #save screenshot as test.jpg
break
camera.release()
cv2.destroyAllWindows()
To get a better burst effect, I changed the code to include time.sleep functions between when imwrite is being used. However, when I use this code, all three pictures are exactly the same. I can see that after I press 's' the camera feed is open, but the frame freezes. I don't know how to keep the frame live so that all the burst pictures are actually different.
camera = cv2.VideoCapture(1)
if camera.read() == (False,None):
camera= cv2.VideoCapture(0)
else:
pass
while True:
return_value,image = camera.read()
gray = cv2.cvtColor(image,cv2.COLOR_BGR2GRAY)
cv2.imshow('image',gray)
if cv2.waitKey(1)& 0xFF == ord('s'): #take a screenshot if 's' is pressed
cv2.imwrite('burst.png,image)
time.sleep(1)
cv2.imwrite('burst1.png',image)
time.sleep(1)
cv2.imwrite('burst2.png',image)
break
camera.release()
cv2.destroyAllWindows()
