需要用到的接口：
获取人脸信息的接口：https://api-cn.faceplusplus.com/facepp/v3/detect
实现换脸的接口 ：https://api-cn.faceplusplus.com/imagepp/v1/mergeface
代码分为三步
代码：
import requests
import json
import simplejson
import base64
#第一步：获取人脸关键点
def find_face(imgpath):
"""
:param imgpath: 图片的地址
:return: 一个字典类型的人脸关键点 如：{'top': 156, 'left': 108, 'width': 184, 'height': 184}
"""
http_url = 'https://api-cn.faceplusplus.com/facepp/v3/detect' #获取人脸信息的接口
data = {
"api_key":"x2NyKaa6vYuArYwat4x0-NpIbM9CrwGU",#访问url所需要的参数
"api_secret":"OuHx-Xaey1QrORwdG7QetGG5JhOIC8g7",#访问url所需要的参数
"image_url":imgpath, #图片地址
"return_landmark":1
}
files = {'image_file':open(imgpath,'rb')} #定义一个字典存放图片的地址
response = requests.post(http_url,data=data,files=files)
res_con1 = response.content.decode('utf-8')
res_json = simplejson.loads(res_con1)
faces = res_json['faces']
list = faces[0]
rectangle = list['face_rectangle']
return rectangle
#第二步：实现换脸
def merge_face(image_url1,image_url2,image_url,number):
"""
:param image_url1: 被换脸的图片路径
:param image_url2: 换脸的图片路径
:param image_url: 换脸后生成图片所保存的路径
:param number: 换脸的相似度
"""
#首先获取两张图片的人脸关键点
face1 = find_face(image_url1)
face2 = find_face(image_url2)
#将人脸转换为字符串的格式
rectangle1 = str(str(face1['top']) + "," + str(face1['left']) + "," + str(face1['width']) + "," + str(face1['height']))
rectangle2 = str(str(face2['top']) + "," + str(face2['left']) + "," + str(face2['width']) + "," + str(face2['height']))
#读取两张图片
f1 = open(image_url1,'rb')
f1_64 = base64.b64encode(f1.read())
f1.close()
f2 = open(image_url2, 'rb')
f2_64 = base64.b64encode(f2.read())
f2.close()
url_add = 'https://api-cn.faceplusplus.com/imagepp/v1/mergeface' #实现换脸的接口
data={
"api_key": "x2NyKaa6vYuArYwat4x0-NpIbM9CrwGU",
"api_secret": "OuHx-Xaey1QrORwdG7QetGG5JhOIC8g7",
"template_base64":f1_64,
"template_rectangle":rectangle1,
"merge_base64":f2_64,
"merge_rectangle":rectangle2,
"merge_rate":number
}
response1 = requests.post(url_add,data=data)
res_con1 = response1.content.decode('utf-8')
res_dict = json.JSonDecoder().decode(res_con1)
result = res_dict['result']
imgdata = base64.b64decode(result)
file=open(image_url,'wb')
file.write(imgdata)
file.close()
if __name__ == '__main__':
image1 = r"meizi1.jpg"
image2 = r"meizi.jpg"
image3 = r"face1.jpg"
merge_face(image1,image2,image3,100)
效果：
换脸前
要换的脸：
换脸后：
