表格识别 -文本识别 - 华为开发者联盟

能力描述

表格结构 文本识别

表格识别API是基于聚焦拍照OCR的识别技术,可以实现对图像表格的结构化识别, 包括单元格的位置信息,单元格的占用行列数,以及每个单元格内的文本信息。 本API可应用于办公类软件,将图像中的表格完美还原为excel文件。
应用场景

表格还原 内容识别

提取表格文本、结构信息, 适用于基于各种表格内容识别的业务场景,如三方APP可以利用引擎返回的结果生成excel文件,减少人工录入的成本。

表格图像恢复为excel文件

利用API的返回的表格结构信息,可将原图像中的表格识别出来生成excel文件,用于对表格的再编辑。

完全还原电子表格信息

利用API的返回的文本框信息,在恢复表格结构的基础上,结合原图,可以完全还原原图中表格内文字的字号、颜色和字体等信息。

FAQ
1没有调用接口的prepare()方法可以直接使用faceCompare()方法吗?

可以的,在faceCompare()方法中会默认启动引擎,如果引擎已经启动则不会再次启动,开发者可以放心使用。

2表格识别需要像聚焦拍照OCR那样配置configuation吗?

暂时不需要。目前表格识别功能相对单一,不需要额外配置信息。

3release()方法是什么时候调用?

release()方法会卸载在NPU芯片中已经加载的模型,请在应用不再使用表格识别时及时卸载模型,释放资源。
