Computer Vision : Setting Camera Parameters in OpenCV Python


 control window size






import cv2

cap = cv2.VideoCapture(0)

print(cap.get(cv2.CAP_PROP_FRAME_WIDTH))

print(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))


cap.set(3, 3000) #set your frame width

cap.set(4, 3000) #set your frame height


print(cap.get(3)) #get your frame width

print(cap.get(4)) #get your frame height


while(cap.isOpened()):#while camera is open

    ret, frame = cap.read()#read frames        

    if ret == True: #still there is a frame to process        

     gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY                 

       cv2.imshow('frame', gray)                 

               if cv2.waitKey(1) & 0xFF == ord('q'):#wait key from keyboard                 

         break                     

    else: #if ret=false         

        break              


cap.release()#close camera

cv2.destroyAllWindows()#close window
