Question

我尝试使用opencv，webcam和python作为项目来创建动作检测报警。我创建了动作检测，并希望添加邮件提醒和短信提醒等功能但是当我调用我的邮件代码时屏幕滞后大约5秒钟。我需要在检测到动作后立即提醒用户。这是我的动作检测代码

def detect(img, feed):
motiondetect = False
temp = img.copy()
contours, hierarchy = findContours(temp, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
if len(contours) > 20 :
    motiondetect = True


else:
    motiondetect = False

return motiondetect


cap = cv2.VideoCapture(0)
pr = False
font = cv2.FONT_HERSHEY_SIMPLEX
recording = False
startr = True
send=True
fourcc = cv2.cv.CV_FOURCC(*'IYUV')
count = 0
out = cv2.VideoWriter()
while True:
ret, img = cap.read()
if startr == True:
    out = cv2.VideoWriter("E:/vid" + str(count) + ".avi", fourcc, 6, (640, 480), 1)
    startr = False


img = cv2.resize(img, (640, 480))
grayimg = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
ret, img2 = cap.read()
grayimg2 = cv2.cvtColor(img2, cv2.COLOR_BGR2GRAY)
diffimg = cv2.absdiff(grayimg, grayimg2)
m, thresimg = cv2.threshold(diffimg, 20, 255, cv2.THRESH_BINARY)
thresimg = cv2.blur(thresimg, (10, 10))
n, thresimg = threshold(thresimg, 20, 255, cv2.THRESH_BINARY)
motionn = detect(thresimg, img)
now = datetime.datetime.now()
mm = str(now.month)
dd = str(now.day)
yy = str(now.year)
hour = str(now.hour)
if (int(hour) < 10):
    hour = "0" + str(hour)
mi = str(now.minute)
if (int(mi) < 10):
    mi = "0" + str(mi)
ss = str(now.second)
if (int(ss) < 10):
    ss = "0" + str(ss)
pdt = dd + "-" + mm + "-" + yy + " " + hour + ":" + mi + ":" + ss
cv2.rectangle(img, (0, 460), (200, 480), (255, 255, 255), -1)
cv2.putText(img, str(pdt), (10, 473), font, 0.5, (0, 0, 0), 2)
if (motionn == True):
    recording = True



else:
    recording = False
if (recording == True):
    out.write(img)
    cv2.putText(img, "Motion Detected", (0, 420), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 0, 255), 2)


imshow("Window", img)


k = waitKey(20)
if k == 27:
    break
elif k == 110:
    count = count + 1
    startr = True
elif k == 114:
    if (startr == False):
        startr = True

cap.release()
cv2.destroyAllWindows()

我应该在哪里调用邮件功能？谢谢你的帮助
