保险单识别

功能介绍

识别保险单图片上的文字信息，并将识别的结构化结果返回给用户。支持对多板式保险单的扫描图片及手机照片进行结构化信息提取。

约束与限制

  • 只支持识别PNG、JPG、JPEG、BMP、TIFF格式图片。
  • 图像各边的像素在15px到8192px之间。
  • 图像中保险单区域有效占比超过70%，保证整张保险单及其边缘包含在图像内。
  • 支持图像中保险单旋转、支持少量扭曲。
  • 能处理暗光等干扰的图片但影响识别精度。
  • 覆盖常见保险公司的常见保单版式，由于即使是同一家保险公司，保险种类也繁多而且都在动态变化，实际支持情况请以实际测试效果为准。

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和认证鉴权章节。

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/insurance-policy

表1 路径参数

参数

是否必选

说明

endpoint

是

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”为“ocr.cn-north-4.myhuaweicloud.com”。

project_id

是

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

是

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

是

String

发送的实体的MIME类型，参数值为“application/json”。

Enterprise-Project-Id

否

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

否

String

与url二选一。

图片的Base64编码，要求Base64编码后大小不超过10MB。

图片最短边不小于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

否

String

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。

detect_direction

否

Boolean

是否校正图片的倾斜角度，可选值如下。

  • true：校正图片的倾斜角度
  • false：不校正图片的倾斜角度

支持任意角度的校正，未传入该参数时默认为“false”。

待识别图片如果存在倾斜，建议将此参数设置为“true”。
