Python 3.x 如何使用dlib获得眼睛和嘴巴的长度

我正在做一个哈欠检测项目，我正在使用dlib和opencv检测视频中的人脸和地标

我想知道眼睛和嘴巴的长度

这就是我到现在为止所做的

import sys
import os
import dlib
import glob
from skimage import io
import cv2
import time

if len(sys.argv) != 3:
    print("")
    exit()

predictor_path = sys.argv[1]
faces_folder_path = sys.argv[2]

vidcap = cv2.VideoCapture('video.avi')

detector = dlib.get_frontal_face_detector()
predictor = dlib.shape_predictor(predictor_path)
win = dlib.image_window()

while vidcap.isOpened():
    success, image = vidcap.read()
    if success:
        win.clear_overlay()
        win.set_image(image)

        # Ask the detector to find the bounding boxes of each face. The 1 in the
        # second argument indicates that we should upsample the image 1 time. This
        # will make everything bigger and allow us to detect more faces.
        dets = detector(image, 1)
        print("Number of faces detected: {}".format(len(dets)))
        for k, d in enumerate(dets):
            print("Detection {}: Left: {} Top: {} Right: {} Bottom: {}".format(
            k, d.left(), d.top(), d.right(), d.bottom()))
            # Get the landmarks/parts for the face in box d.
            shape = predictor(image, d)
            print(shape)
            print("Part 0: {}, Part 1: {},Part 2: {} ...".format(shape.part(0),shape.part(1),shape.part(2)))
            # Draw the face landmarks on the screen.
            win.add_overlay(shape)
            win.add_overlay(dets)
        time.sleep(0.01)
cv2.destroyAllWindows()
vidcap.release()

请帮助我如何得到眼睛和嘴巴张开的长度

为什么不测量形状和零件之间的距离？
