哥伦比亚身份证识别
功能介绍
识别哥伦比亚身份证中的文字信息,并将识别的结构化结果返回给用户。
约束与限制
- 支持哥伦比亚身份证的识别。
- 只支持识别PNG、JPG、JPEG、BMP、TIFF格式图片。
- 图像各边的像素大小在15px到8192px之间。
- 图像中身份证区域有效占比超过80%,保证整张身份证内容及其边缘包含在图像内。
- 支持图像中身份证任意角度的水平旋转。
- 支持少量扭曲,扭曲后图像中的身份证长宽比与实际身份证相差不超过10%。
- 能处理反光、暗光等干扰的图片但影响识别精度。
- 目前只支持识别单张身份证的正面或者反面。
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。

请求参数
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。 |
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。

参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
image |
否 |
String |
该参数与url二选一。 图像数据,base64编码,要求base64编码后大小不超过10M。图片最短边不小于15像素,最长边不超过8192像素,支持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。 |
