澳门身份证识别

功能介绍

识别中国-澳门身份证图片中的文字内容，并将识别的结果返回给用户。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

只支持识别PNG、JPG、JPEG、BMP、TIFF格式的图片。
图像各边的像素大小在15到8192px之间。
图像中身份证区域有效占比超过50%，保证整张身份证内容及其边缘包含在图像内。
支持图像任意角度的水平旋转但影响识别精度。
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

在使用中国-澳门身份证识别之前，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/macao-id-card

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	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15像素，最长边不超过8192像素。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。
side	否	String	front：身份证正面 back：身份证背面如果参数值为空或无该参数，系统自动识别，建议填写，准确率更高。
return_portrait_image	否	Boolean	是否返回头像内容开关，可选值如下所示。 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。

响应参数

状态码： 200

表4 响应Body参数
参数	参数类型	描述
result	MacaoIdCardResult object	调用成功时表示调用结果。调用失败时无此字段。

表5 MacaoIdCardResult
参数	参数类型	描述
side	String	证件图片正反面信息。可选值包括： "front": 证件图片为正面 "back": 证件图片为反面
name	String	姓名。
name_en	String	英文姓名，姓名单词之间使用空格进行间隔。
sex	String	性别，返回“男”或“女”。
issue_date	String	本次发证日期。
expiry_date	String	证件有效期。
birth_date	String	出生日期。
initial_issue_date	String	首次发证日期。
height	String	身高。
number	String	身份证号。
symbols	String	身份证上的字母代码，表示出生地等信息。
machine_code1	String	身份证背面第一行机器码。
machine_code2	String	身份证背面第二行机器码。
machine_code3	String	身份证背面第三行机器码。
portrait_image	String	身份证头像照片的Base64编码。若入参“return_portrait_image”字段缺失时，则此字段不存在。
confidence	Object	相关字段的置信度信息，置信度越大，表示本次识别的对应字段的可靠性越高，在统计意义上，置信度越大，准确率越高。注：置信度由算法给出，不直接等价于对应字段的准确率。

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。调用成功时无此字段。
error_msg	String	调用失败时的错误信息。调用成功时无此字段。
