柬文身份证识别

功能介绍

识别柬文身份证图片中的文字内容，并将识别的结构化结果返回给用户。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

目前只支持单张柬文身份证正面识别。
只支持识别PNG、JPG、BMP、TIFF格式的图片。
图像各边的像素大小在15到8192px之间。
支持图像中柬文身份证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

在使用柬文身份证识别之前，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/cambodian-idcard

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。
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	与url二选一。图片的Base64编码。图片尺寸不小于15像素，最长边不超过8192像素，支持JPG/PNG/BMP/TIF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，目前仅支持华为云上OBS提供的匿名公开授权访问的URL以及公网URL。
return_portrait_image	否	Boolean	是否返回身份证头像照片的 Base64 编码，可选值如下： true: 返回身份证头像照片的 Base64 编码 false: 不返回身份证头像照片的 Base64 编码未传入该参数时默认为“false”，即不返回身份证头像照片的 Base64 编码。
return_portrait_location	否	Boolean	是否返回头身份证头像的位置坐标，可选值如下： true: 返回身份证头像的位置坐标 false: 不返回身份证头像的位置坐标未传入该参数时默认为“false”，即不返回身份证的头像坐标。
return_idcard_type	否	Boolean	是否返回身份证类型，可选值如下： true:返回身份证类型，类型包括身份证原件和身份证复印件 false：不返回身份证的类型

响应参数

状态码： 200

表4 响应Body参数
参数	参数类型	描述
result	CambodianIdCardResult object	识别结果。调用失败时此字段为空。

表5 CambodianIdCardResult
参数	参数类型	描述
id_number	String	身份证号码。
name_kh	String	高棉语版姓名。
name_en	String	英文姓名。
birth_date	String	出生日期。
sex	String	性别。
height	String	身高。
birth_place	String	出生地。
address	String	地址，以空格分隔。
issue_date	String	签发起始日期。
expiry_date	String	签发结束日期。
description	String	图片中的个人特征。
machine_code1	String	机器码第一行。
machine_code2	String	机器码第二行。
machine_code3	String	机器码第三行。
portrait_image	String	头像的base64编码。当输入参数“return_portrait_image”为“true”时，才返回该参数。
portrait_location	Array<Array<Integer>>	头像在原图上的位置。当输入参数“return_portrait_location”为“true”时，才返回该参数。以列表形式显示，包含头像区域四个顶点的二维坐标（x,y），坐标原点为图片左上角，x轴沿水平方向，y轴沿竖直方向。
idcard_type	String	身份证的类型。当输入参数“ idcard_type ”为“true”时，才返回该参数。取值如下所示： normal：身份证原件 copy：复印的身份证
confidence	Object	字段的置信度，取值范围0~1。置信度越大，本次识别的字段的可靠性越高，在统计意义上，置信度越大，准确率越高。置信度由算法给出，不直接等价于字段的准确率。

状态码： 400

表6 响应Body参数
参数	参数类型	描述
error_code	String	调用失败时的错误码，具体请参见错误码。调用成功时不返回此字段。
error_msg	String	调用失败时返回的错误信息。调用成功时不返回此字段。
