创建人脸库

功能介绍

创建用于存储人脸特征的人脸库。您最多可以创建10个人脸库，每个人脸库最大容量为10万个人脸特征。如有更大规格的需求请联系客服。

前提条件：

请确保您已开通人脸搜索服务。

• 默认情况下，一个人脸库最大可支持10万个人脸特征，一个用户最多可创建10个人脸库，最多可支持10*10万（100万）个人脸特征。
• 如您的需求超出100万个人脸特征，可通过工单或者服务热线（ 4000-955-988或950808 转1）与我们联系，咨询具体解决方案。

调试

您可以在API Explorer中调试该接口，支持自动认证鉴权。API Explorer可以自动生成SDK代码示例，并提供SDK代码示例调试功能。

• 创建人脸库，并设置为可存储10万个人脸特征

  POST https://{endpoint}/v2/{project_id}/face-sets
  Request Header:
  Content-Type: application/json
  X-Auth-Token: MIINRwYJKoZIhvcNAQcCoIINODCCDTQCAQExDT...
  
  Request Body:
  {
    "face_set_name": "test", 
    "face_set_capacity": 100000,
    "external_fields" : {
      "timestamp" : {
        "type" : "long"
      },
      "id" : {
        "type" : "string"
      },
      "number" : {
        "type" : "integer"
      }
    }
  
  }

• 使用Python3语言创建人脸库，并设置为可存储10万个人脸特征

  # -*- coding:utf-8 -*-
  
  import requests
  import base64
  
  endpoint = '开通服务所在region的人脸识别服务域名'
  project_id = '开通服务所在region的用户项目ID'
  token = '用户获取得到的实际token值'
  headers = {'Content-Type': 'application/json', 'X-Auth-Token': token}
  
  url = "https://{endpoint}/v2/{project_id}/face-sets".format(endpoint=endpoint,project_id=project_id)
  body = {
    "face_set_name": "test", 
    "face_set_capacity": 100000,
    "external_fields" : {
      "timestamp" : {
        "type" : "long"
      },
      "id" : {
        "type" : "string"
      },
      "number" : {
        "type" : "integer"
      }
    }
  }
  response = requests.post(url, headers=headers, json=body, verify=False)
  print(response.text)
