上述代码运行报错AttributeError: module 'dlib' has no attribute 'face_distance'

非常抱歉,我之前给出的代码有误。dlib库中确实没有`face_distance`函数。实际上,我们可以通过计算两个人脸特征向量之间的欧氏距离来衡量相似度。下面是修正后的代码:
```python
import dlib
import cv2
import numpy as np
def get_face_landmarks(img):
detector = dlib.get_frontal_face_detector()
predictor = dlib.shape_predictor("shape_predictor_68_face_landmarks.dat")
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = detector(gray)
for face in faces:
landmarks = predictor(gray, face)
return landmarks
def get_face_descriptor(img):
face_landmarks = get_face_landmarks(img)
face_rec_model = dlib.face_recognition_model_v1("dlib_face_recognition_resnet_model_v1.dat")
face_descriptor = face_rec_model.compute_face_descriptor(img, face_landmarks)
return face_descriptor
def compare_faces(img1, img2):
face_descriptor1 = get_face_descriptor(img1)
face_descriptor2 = get_face_descriptor(img2)
# 计算欧氏距离
euclidean_distance = np.linalg.norm(face_descriptor1 - face_descriptor2)
# 归一化处理,范围在0-1之间,相似度越高越接近0
similarity = 1 / (1 + euclidean_distance)
return similarity
# 读取两张人脸图片
img1 = cv2.imread("image1.jpg")
img2 = cv2.imread("image2.jpg")
# 比对两张图片的相似度
similarity = compare_faces(img1, img2)
print("相似度:", similarity)
```
请确保已经下载了dlib的模型文件(`shape_predictor_68_face_landmarks.dat` 和 `dlib_face_recognition_resnet_model_v1.dat`)。这段代码将比较两张人脸图片的相似度,并输出结果。相似度值越接近0表示两张图片的人脸越相似。
