  • dlib安装测试

    1.在vs2019+Anaconda+python3.7环境下安装

    打开Anaconda prompt选定一个python环境,安装cmake和boost

    pip install cmake -i https://pypi.tuna.tsinghua.edu.cn/simple

    pip  install  boost -i https://pypi.tuna.tsinghua.edu.cn/simple

    2.编译dlib。

    从官网下载python3.7 dlib源文件。

     https://pypi.org/project/dlib/#files

    在Anaconda prompt中输入pyhton setup.py install,进行编译。

     等待结束dlib编译成功。

    3.安装opencv 

    pip install opencv-python==3.4.1.15 -i https://pypi.tuna.tsinghua.edu.cn/simple

    pip install opencv-contrib-python==3.4.1.15 -i https://pypi.tuna.tsinghua.edu.cn/simple

    4.下载人脸关键点检测模型

     5.打开jupyter选择安装dlib的python环境,import dlib进行测试

     1 import numpy as np
     2 import cv2
     3 import dlib
     4 
     5 detector = dlib.get_frontal_face_detector()
     6 predictor = dlib.shape_predictor('E:/shape_predictor_68_face_landmarks.dat')
     7 
     8 # cv2读取图像
     9 img = cv2.imread("E:/test.jpg")
    10 
    11 # 取灰度
    12 img_gray = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY)
    13 
    14 # 人脸数rects
    15 rects = detector(img_gray, 0)
    16 for i in range(len(rects)):
    17     landmarks = np.matrix([[p.x, p.y] for p in predictor(img,rects[i]).parts()])
    18     for idx, point in enumerate(landmarks):
    19         # 68点的坐标
    20         pos = (point[0, 0], point[0, 1])
    21         print(idx,pos)
    22 
    23         # 利用cv2.circle给每个特征点画一个圈,共68个
    24         cv2.circle(img, pos, 2, color=(0, 255, 0))
    25         # 利用cv2.putText输出1-68
    26         font = cv2.FONT_HERSHEY_SIMPLEX
    27         cv2.putText(img, str(idx+1), pos, font, 0.3, (0, 0, 255), 1,cv2.LINE_AA)
    28 
    29 cv2.namedWindow("img", 2)
    30 cv2.imshow("img", img)
    31 cv2.waitKey(0)
