Python用opencv+dlib实现人脸识别

代码：

#coding=utf-8

import cv2
import dlib

path = "imagePath/9.jpg"
img = cv2.imread(path)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

#人脸分类器
detector = dlib.get_frontal_face_detector()
# 获取人脸检测器
predictor = dlib.shape_predictor(
    "shape_predictor_68_face_landmarks.dat"
)

dets = detector(gray, 1)
if len(dets):  # 大于0则检测到人脸
    for face in dets:
        shape = predictor(img, face)  # 寻找人脸的68个标定点
        # 遍历所有点，打印出其坐标，并圈出来
        for pt in shape.parts():
            pt_pos = (pt.x, pt.y)
            cv2.circle(img, pt_pos, 1, (0, 255, 0), 2)
        cv2.imshow("image", img)
        k = cv2.waitKey(0)
        if k == ord("s"):
            cv2.imwrite("imagePath/2-4.png", img)
    cv2.destroyAllWindows()
else:
    print(\'没找到人脸！\')

效果：

 

 会标出68个人脸的特征点。
