户口本识别

功能介绍

识别户口本中的文字信息,并返回识别的结构化结果。该接口的使用限制请参见约束与限制,详细使用指导请参见OCR服务使用简介章节。

该接口的使用限制请参见约束与限制,详细使用指导请参见OCR服务使用简介章节。

约束与限制

  • 只支持识别PNG、JPG、JPEG、BMP、TIFF格式的图片。
  • 图像各边的像素在15到8192px之间。
  • 支持多页同时识别。
  • 能处理反光、暗光、水印等干扰的图片但影响识别精度。
  • 文字识别服务属于公有云服务,线上用户资源共享,如果需要多并发请求,请提前联系我们

调用方法

请参见如何调用API

前提条件

在使用之前,需要您完成服务申请和认证鉴权,具体操作流程请参见开通服务认证鉴权章节。

用户首次使用需要先申请开通。服务只需要开通一次即可,后面使用时无需再次申请。如未开通服务,调用服务时会提示ModelArts.4204报错,请在调用服务前先进入控制台开通服务,并注意开通服务区域与调用服务的区域保持一致。

URI

POST /v2/{project_id}/ocr/household-register

表1 路径参数

参数

是否必选

说明

endpoint

终端节点,即调用API的请求地址。

不同服务不同区域的endpoint不同,您可以从终端节点中获取。

例如,OCR服务在“华北-北京四”区域的“endpoint”“ocr.cn-north-4.myhuaweicloud.com”

project_id

项目ID,您可以从获取项目ID中获取。

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

用户Token。

用于获取操作API的权限。获取Token接口响应消息头中X-Subject-Token的值即为Token。

Content-Type

String

发送的实体的MIME类型,参数值为“application/json”。

Enterprise-Project-Id

String

企业项目ID。OCR支持通过企业项目管理(EPS)对不同用户组和用户的资源使用,进行分账。

获取方法:进入“企业项目管理”页面,单击企业项目名称,在企业项目详情页获取Enterprise-Project-Id(企业项目ID)。

企业项目创建步骤请参见用户指南。

说明:

创建企业项目后,在传参时,有以下三类场景。

  • 携带正确的ID,正常使用OCR服务,账单的企业项目会被分类到企业ID对应的企业项目中。
  • 携带格式正确但不存在的ID,正常使用OCR服务,账单的企业项目会显示对应不存在的企业项目ID。
  • 不携带ID或格式错误ID(包含特殊字符等),正常使用OCR服务,账单的企业项目会被分类到"default"中。
表3 请求Body参数

参数

是否必选

参数类型

描述

image

String

与url二选一。

图片的Base64编码,要求base64编码后大小不超过10MB。

图片最小边不小于15px,最长边不超过8192px,支持JPEG、JPG、PNG、BMP、TIFF格式。

图片Base64编码示例如/9j/4AAQSkZJRgABAg...,带有多余前缀会产生The image format is not supported报错。

url

String

该参数与image二选一。图片的url路径,目前支持:

  • 公网http/https url
  • OBS提供的url,使用OBS数据需要进行授权。包括对服务授权、临时授权、匿名公开授权,详情参见配置OBS访问权限
说明:
  • 接口响应时间依赖于图片的下载时间,如果图片下载时间过长,会返回接口调用失败。
  • 请保证被检测图片所在的存储服务稳定可靠,推荐使用OBS服务存储图片数据。
  • url中不能存在中文字符,若存在,中文需要进行utf8编码。

响应参数

根据识别的结果,可能有不同的HTTP响应状态码(status code)。例如,200表示API调用成功,400表示调用失败,详细的状态码和响应参数说明如下。

状态码: 200

表4 响应Body参数
