python+opencv虚化边缘

import cv2
import numpy as np

cap=cv2.VideoCapture(0,cv2.CAP_DSHOW)

cap.open(0)

while cap.isOpened():
    flag,frame=cap.read()
    if not flag:
        break
    key_pressed=cv2.waitKey(60)
    print('键盘上输入的是',key_pressed)
    frame=cv2.resize(frame,(600,600))

    frame=cv2.Canny(frame,100,200)

    frame=np.dstack((frame,frame,frame))

    cv2.imshow('my computer',frame)

    if key_pressed==27:
        break

cap.release()

cv2.destroyAllWindows()

需要安装opencv-python库和numpy库
