飞机行程单识别

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
点击放大

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。单个图片对应的Base64编码不超过10MB。
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/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	说明
image	否	String	该参数与url二选一。图片的Base64编码，单个图片其对应的Base64编码不超过10MB。图片在Base64编码后会大于图片原本大小，请注意做好边界判断，建议图片大小不超过7MB。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。url中单个图片其对应的Base64编码不超过10MB。图片在Base64编码后会大于图片原本大小，请注意做好边界判断，建议图片大小不超过7MB。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
