当我使用 opencv-python 版本 v4.3.0 在我的笔记本中运行这个简单的代码时。然后我的屏幕充满了窗口,如图所示。
# importing the required modules
import cv2
import numpy as np
# capturing from the first camera attached
cap = cv2.VideoCapture(0)
# will continue to capture until 'q' key is pressed
while True:
ret, frame = cap.read()
# Capturing in grayscale
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
cv2.imshow('frame', frame)
cv2.imshow('gray', gray)
# Program will terminate when 'q' key is pressed
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# Releasing all the resources
cap.release()
cv2.destroyAllWindows()
