本接口核心能力

分类概述
图片格式支持PNG、JPG、JPEG、BMP、GIF、TIFF、WebP。
图像增强默认支持图像增强，包括图像自动旋转、畸变自动矫正、模糊图片自动增强等能力。
多类型覆盖支持模糊、光照不均、透视畸变、任意背景等低质量图像识别。
高精度识别总体识别准确率可达98%。

如何使用本接口

步骤概述
1开通 医疗场景识别 服务。开通服务前后，您可以通过体验馆免费体验本功能识别效果。
2购买核酸检测报告识别资源包。本API会赠送免费额度，可使用免费额度测试。
3可以参照调试页面提供的代码示例完成API接入开发。接入完成后，调用API获取识别结果。如果使用子账号调用接口，需要阿里云账号（主账号）对RAM账号进行授权。创建RAM用户的具体操作，请参考：创建RAM用户。文字识别服务提供一种系统授权策略，即AliyunOCRFullAccess。具体授权操作，请参见在用户页面为RAM用户授权。

重要提示

类型概述
图片格式
  • 本接口支持：PNG、JPG、JPEG、BMP、GIF、TIFF、WebP。暂不支持PDF格式。
图片尺寸
  • 图片长宽需要大于15像素，小于8192像素。
  • 长宽比需要小于50。
  • 如需达到较好识别效果，建议长宽均大于500px。
图片大小
  • 图片二进制文件不能超过10MB。
  • 图片过大会影响接口响应速度，建议使用小于1.5M图片进行识别，且通过传图片URL的方式调用接口。
其他提示
  • 接口响应速度和图片中的文字数量有关，如果图片中文字数量越多，接口响应可能越慢。
  • 接口会自动处理反光、扭曲等干扰信息，但会影响精度。请尽量选择清晰度高、无反光、无扭曲的图片。

调试

您可以在OpenAPI Explorer中直接运行该接口，免去您计算签名的困扰。运行成功后，OpenAPI Explorer可以自动生成SDK代码示例。
