This is a program to detect eyes closed. But i want after eyes closed 3 seconds, it will print "Warning" in terminal.

      for (x, y, w, h) in faces:
            cv2.rectangle(image, (x, y), (x + w, y + h), (255, 255, 0), 2)

            roi_gray = gray[y:y+h, x:x+w]
            roi_color = image[y:y+h, x:x+w]
            eyes = eyesCascade.detectMultiScale(roi_gray)
            if eyes is not():
                for (ex,ey,ew,eh) in eyes:
                    cv2.rectangle(roi_color,(ex -10 ,ey - 10),(ex+ew + 10,ey+eh + 10),(0,255,0),2)
                    twoeyes = twoeyesCascade.detectMultiScale(roi_gray)
                    checkyeys = 0
                    if twoeyes is not():
                        for (exx,eyy,eww,ehh) in twoeyes:
                            checkyeys = 0
                            led.write(1)
                            cv2.rectangle(roi_color,(exx-5 ,eyy -5  ),(exx+eww -5,eyy+ehh -5 ),(0,0, 255),2)
                    else:
                        #when eyes close
                        print "------------------------------------"

And how do you think this will work? The cascade will trigger way to many false positives on closed eyes to ever get this to work. It is not robust enough for this task.

You can suggest a few alternatives feasible.

I think "eyes = eyesCascade.detectMultiScale(roi_gray)" will detect eyes area And " twoeyes = twoeyesCascade.detectMultiScale(roi_gray)" will detect two eyes. When I see eyes area but don't see two eyes that's when detect closed eyes.

That won't work. Also, I only know of a right and left eye model and a general eye model, but there isn't a combined one. So where did you get that model?

Thanks you! How to you know if eyes closed in 3 seconds

For that you will need to either

  • Train a seperate model for open and one for closed eyes, using the positives of model one as negatives for the second one
  • Or use a single eye detector, then train an SVM to classify each eye as open or closed
