介绍
PaddleOCRSharp 是一个基于百度飞桨PaddleOCR的开源代码修改并优化的.NET版本OCR可离线使用类库。项目核心组件PaddleOCR.dll,由C++编写,根据百度飞桨PaddleOCR的C++代码修改并优化而成。目前已经支持C++、.NET、Python、Golang、Rust等众多开发语言的直接API接口调用。项目包含文本识别、文本检测、表格识别功能。本项目针对小图识别不准的情况下做了优化,同时做了其他优化,比飞桨原代码识别准确率有所提高,速度更快。包含总模型仅8.6M的超轻量级中文OCR,单模型支持中英文数字组合识别、竖排文本识别、长文本识别。同时支持中英文、纯英文以及多种语言文本检测识别。
PaddleOCRSharp封装极其简化,实际调用仅几行代码,极大的方便了中下游开发者的使用和降低了PaddleOCR的使用入门级别,同时提供不同的.NET框架使用,方便各个行业应用开发与部署。Nuget包即装即用,可以离线部署,不需要网络就可以识别的高精度中英文OCR。
本项目支持官方所有公开的通用OCR模型,PPOCRV2、PPOCRV3、PPOCRV4。 如果使用v2模型,请设置OCR识别参数OCRParameter对象的属性rec_img_h=32 ,最新版本默认使用V4模型,默认rec_img_h=48:
本项目支持在x86的CPU上使用,CPU指令集需要包含avx指令集。
★windows系统支持:win7SP1、win10、win11、winserver2012R2、winserver2016、winserver2019、winserver2022等
★linux系统支持:统信UOS、麒麟、ubuntu等。
本项目目前支持以下.NET框架:
net35;net40;net45;net451;net452;net46;net461;net462;net47;net471;net472;net48;net481;
netstandard2.0;netcoreapp3.1;
net5.0;net6.0;net7.0;net8.0
特点
★ $\color{#0000FF}{高度集成}$:PaddleOCRSharp将百度飞桨PaddleOCR的核心功能完美集成到.NET平台,让开发者无需关心底层实现,只需调用相应接口即可实现OCR功能。
★ $\color{#0000FF}{性能卓越}$:得益于百度飞桨PaddleOCR的高效算法和C++代码的优化,PaddleOCRSharp在保持高度集成的同时,也保证了卓越的性能表现。
★ $\color{#0000FF}{易于使用}$:PaddleOCRSharp提供了丰富的API接口和详细的文档说明,让开发者能够轻松上手,快速实现OCR功能。
★ $\color{#0000FF}{扩展性强}$:PaddleOCRSharp支持自定义模型加载和训练,开发者可以根据自己的需求进行模型扩展和优化。
★ $\color{#FF0000}{离线免费}$:PaddleOCRSharp支持离线绿色部署,无其他依赖需要安装,关键普通版还免费,满足了众多开发者的福音。
应用场景
PaddleOCRSharp适用于各种需要OCR技术的.NET开发场景,如文档数字化处理、自动识别表单数据、车牌识别等。无论是企业级应用还是个人开发者,PaddleOCRSharp都能提供强大的OCR支持。
如何使用
本项目提供了两个SDK,一个是C++版本,一个是.net版本,.net版本是对C++版本的二次封装,其他语言开发亦是调用C++版本。同时也提供了Go、Python、C++的调用示例代码
1.文件夹结构
PaddleOCRSharp //该文件夹包含.NET对PaddleOCR封装类库项目
Demo //该文件夹包含OCR示例Demo文件夹
|--Cpp //C++调用示例项目
|--CSharp //.NET调用示例项目
|--python //python调用示例项目
|--Go ///Golang调用示例项目
2. .NET版编译
使用与部署
1. C++使用PaddleOCR
2. .NET使用PaddleOCRSharp
3. python使用PaddleOCR
4. Go使用PaddleOCR
5. Rust使用PaddleOCR
OCR模型
OCR识别模型库支持官方所有的模型,也支持自己训练的模型。完全按照飞桨OCR接口搭桥。 本项目部署自带的一种轻量版8.6M模型库、服务器版模型库(更准确,需要自行下载),可以自行更改模型库适用实际需求。
模型名称 | 模型大小 | 下载地址 | 备注 |
---|---|---|---|
ch_PP-OCRv2 | 10M | 中英文轻量v2 | |
en_PP-OCRv2 | 4M | 英文数字v2 | |
ch_PP-OCRv3 | 12M | 中英文轻量v3 | |
en_PP-OCRv3 | 10M | 英文数字v3 | |
ch_PP-OCRv4 | 14M | 中英文轻量v4 | |
en_PP-OCRv4 | 12M | 英文数字v4 |
如果需要修改成服务器版模型库,参考代码如下:(假设服务器版模型库在运行目录的文件夹inferenceserver下)
//自带轻量版中英文模型PP-OCRv4
OCRModelConfig config = null;
OCRParameter oCRParameter = new OCRParameter();
//服务器中英文模型v2
OCRModelConfig config = new OCRModelConfig();
string modelPathroot = "你的模型绝对路径文件夹";
config.det_infer = modelPathroot + @"\ch_ppocr_server_v2.0_det_infer";
config.cls_infer = modelPathroot + @"\ch_ppocr_mobile_v2.0_cls_infer";
config.rec_infer = modelPathroot + @"\ch_ppocr_server_v2.0_rec_infer";
config.keys = modelPathroot + @"\ppocr_keys.txt";
//英文和数字模型v3
OCRModelConfig config = new OCRModelConfig();
string modelPathroot = "你的模型绝对路径文件夹";
config.det_infer = modelPathroot + @"\en_PP-OCRv3_det_infer";
config.cls_infer = modelPathroot + @"\ch_ppocr_mobile_v2.0_cls_infer";
config.rec_infer = modelPathroot + @"\en_PP-OCRv3_rec_infer";
config.keys = modelPathroot + @"\en_dict.txt";
//中英文模型V4
config = new OCRModelConfig();
string modelPathroot = "你的模型绝对路径文件夹";
config.det_infer = modelPathroot + @"\ch_PP-OCRv4_det_infer";
config.cls_infer = modelPathroot + @"\ch_ppocr_mobile_v2.0_cls_infer";
config.rec_infer = modelPathroot + @"\ch_PP-OCRv4_rec_infer";
config.keys = modelPathroot + @"\ppocr_keys.txt";
//服务器中英文模型V4
config = new OCRModelConfig();
string modelPathroot = "你的模型绝对路径文件夹";
config.det_infer = modelPathroot + @"\ch_PP-OCRv4_det_server_infer";
config.cls_infer = modelPathroot + @"\ch_ppocr_mobile_v2.0_cls_infer";
config.rec_infer = modelPathroot + @"\ch_PP-OCRv4_rec_server_infer";
config.keys = modelPathroot + @"\ppocr_keys.txt";
engine = new PaddleOCREngine(config, oCRParameter);
