智能分类识别
功能介绍
自动分类识别17+种票证,支持指定票证的结构化识别和印章检测,并以JSON格式返回识别的结构化结果。
接口以列表形式返回图片上要识别票证的位置坐标、结构化识别的内容以及对应的类别。该接口支持的票证类型请见表1,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。
票证类型 |
|
---|---|
增值税发票 |
增值税发票(销货清单) |
通用机打发票 |
定额发票 |
出租车票 |

智能分类服务只对识别成功的票证进行计费,识别失败的票证不计费。例如,图片中包含三张票证,有两张识别成功,一张识别失败,此时接口计费两次。
约束与限制
- 只支持识别PNG、JPG、JPEG、BMP、TIFF、PDF格式数据。
- 图像各边的像素大小在15px到8000px之间。
- 支持图像中票证任意角度的水平旋转。
- PDF格式数据使用第一页作智能分类。
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。

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,要求Base64编码后大小不超过10MB。 图片最短边不小于15px,最长边不超过8000px,支持JPEG、JPG、PNG、BMP、TIFF、PDF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。图片的url路径,目前支持:
说明:
|
type_list |
否 |
List |
输入图片中,待识别票证的类型,指定后不出现在type_list参数中的票证不识别。不指定时默认返回所有支持类别票证的识别信息。 当前版本支持的票证类型请参见表5。 |
extended_parameters |
否 |
Object |
可指定需要识别票证的传入参数,具体参数可参考各票证API文档。若不指定则默认传入image 。当前版本支持票证类型如下:
增值税发票传参示例: "extended_parameters" : { "vat_invoice" : { "advanced_mode" : true, "return_text_location" : true } } 车船票传参示例: "extended_parameters" : { "bus_ship_ticket":{ "return_text_location" : true //开启返回识别到的文字块的区域位置信息。 } } 通用机打发票传参示例: "extended_parameters" : { "machine_printed_invoice":{ "pdf_page_number" : 1 //指定PDF页码识别,如果不传该参数,则默认识别第1页。 } }
说明:
若指定票证参数填写错误会导致该票证识别错误,会提示"AIS.0101":"The input parameter is invalid."报错。 |
detect_seal |
否 |
Boolean |
检测印章开关,开启时则返回单张票证是否含有印章,否则不返回是否含有印章。可选值包括:
