护照识别

功能介绍

识别护照首页图片中的文字信息，并返回识别的结构化结果。

当前版本支持中国护照的全字段识别。外国护照支持护照下方两行国际标准化的机读码识别，并可从中提取6-7个关键字段信息。

如果图片中包含多张卡证票据，请调用智能分类识别服务。

示例

• 请求样例（方式一：使用图片的BASE64编码）

  POST https://{endpoint}/v1.0/ocr/passport
   
  Request Header:
  Content-Type: application/json
  X-Auth-Token: MIINRwYJKoZIhvcNAQcCoIINODCCDTQCAQExDTALBglghkgBZQMEAgEwgguVBgkqhkiG...
  Request Body:
  {
      "image":"/9j/4AAQSkZJRgABAgEASABIAAD/4RFZRXhpZgAATU0AKgAAAA...",
      "country_code": "GENERAL"
  }

• 请求样例（方式二：使用图片URL）

  POST https://{endpoint}/v1.0/ocr/passport
   
  Request Header:
  Content-Type: application/json
  X-Auth-Token: MIINRwYJKoZIhvcNAQcCoIINODCCDTQCAQExDTALBglghkgBZQMEAgEwgguVBgkqhkiG...
  Request Body:
  {
      "url":"https://BucketName.obs.xxxx.com/ObjectName",
      "country_code": "GENERAL"
  }

  

  Endpoint即调用API的请求地址，不同服务不同区域的Endpoint不同，具体请参见终端节点。

  例如护照识别服务部署在“华北-北京四”区域的Endpoint为“ocr.cn-north-4.myhuaweicloud.com”，请求URL为“https://ocr.cn-north-4.myhuaweicloud.com/v1.0/ocr/passport”。
