飞机行程单识别-凯发k8国际娱乐官网入口

功能介绍

识别飞机行程单中的文字信息，并以json格式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。

图1 飞机行程单示例图

如果图片中包含多张卡证票据，请调用智能分类识别服务。

约束与限制

  • 支持识别png、jpg、jpeg、bmp、tiff格式的图片。
  • 图像各边的像素大小在15px到8192px之间。
  • 支持图像中行程单任意角度的水平旋转。
  • 能处理反光、暗光等干扰的图片但影响识别精度。

调用方法

请参见。

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章节。

用户首次使用需要先。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/flight-itinerary

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。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“”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，账单归到企业id对应的企业项目中。
  • 携带错误的id，正常使用ocr服务，账单的企业项目会被分类为“未归集”。
  • 不携带id，正常使用ocr服务，账单的企业项目会被分类为“未归集”。
表3 请求body参数

参数

是否必选

参数类型

说明

image

否

string

该参数与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

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。
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
