| # PPOCRv3 C++部署示例
 | ||
| 
 | ||
| 本目录下提供`infer.cc`快速完成PPOCRv3在CPU/GPU,以及GPU上通过TensorRT加速部署的示例。
 | ||
| 
 | ||
| 在部署前,需确认以下两个步骤
 | ||
| 
 | ||
| - 1. 软硬件环境满足要求,参考[FastDeploy环境要求](../../../../../docs/cn/build_and_install/download_prebuilt_libraries.md)  
 | ||
| - 2. 根据开发环境,下载预编译部署库和samples代码,参考[FastDeploy预编译库](../../../../../docs/cn/build_and_install/download_prebuilt_libraries.md)
 | ||
| 
 | ||
| 以Linux上CPU推理为例,在本目录执行如下命令即可完成编译测试,支持此模型需保证FastDeploy版本0.7.0以上(x.x.x>=0.7.0)
 | ||
| 
 | ||
| ```
 | ||
| mkdir build
 | ||
| cd build
 | ||
| # 下载FastDeploy预编译库,用户可在上文提到的`FastDeploy预编译库`中自行选择合适的版本使用
 | ||
| wget https://bj.bcebos.com/fastdeploy/release/cpp/fastdeploy-linux-x64-x.x.x.tgz
 | ||
| tar xvf fastdeploy-linux-x64-x.x.x.tgz
 | ||
| cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-linux-x64-x.x.x
 | ||
| make -j
 | ||
| 
 | ||
| 
 | ||
| # 下载模型,图片和字典文件
 | ||
| wget https://paddleocr.bj.bcebos.com/PP-OCRv3/chinese/ch_PP-OCRv3_det_infer.tar
 | ||
| tar -xvf ch_PP-OCRv3_det_infer.tar
 | ||
| 
 | ||
| wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_mobile_v2.0_cls_infer.tar
 | ||

 | ||
| ```
 | ||
| 
 | ||
| 以上命令只适用于Linux或MacOS, Windows下SDK的使用方式请参考:  
 | ||
| - [如何在Windows中使用FastDeploy C++ SDK](../../../../../docs/cn/faq/use_sdk_on_windows.md)
 | ||
| 
 | ||
| 运行完成可视化结果如下图所示

| ## PPOCRv3 C++接口
 | ||
| 
 | ||
| ### PPOCRv3类
 | ||
| 
 | ||
| ```
 | ||
| fastdeploy::pipeline::PPOCRv3(fastdeploy::vision::ocr::DBDetector* det_model,
 | ||
|                 fastdeploy::vision::ocr::Classifier* cls_model,
 | ||
|                 fastdeploy::vision::ocr::Recognizer* rec_model);
 | ||
| ```
 | ||
| 
 | ||
| PPOCRv3 的初始化,由检测,分类和识别模型串联构成
 | ||
| 
 | ||
| **参数**
 | ||
| 
 | ||
| > * **DBDetector**(model): OCR中的检测模型
 | ||
| > * **Classifier**(model): OCR中的分类模型
 | ||
| > * **Recognizer**(model): OCR中的识别模型
 | ||
| 
 | ||
| ```
 | ||
| fastdeploy::pipeline::PPOCRv3(fastdeploy::vision::ocr::DBDetector* det_model,
 | ||
|                 fastdeploy::vision::ocr::Recognizer* rec_model);
 | ||
| ```
 | ||
| PPOCRv3 的初始化,由检测,识别模型串联构成(无分类器)
 | ||
| 
 | ||
| **参数**
 | ||
| 
 | ||
| > * **DBDetector**(model): OCR中的检测模型
 | ||
| > * **Recognizer**(model): OCR中的识别模型
 | ||
| 
 | ||
| #### Predict函数
 | ||
|

| > ```  
 | ||
| > bool Predict(cv::Mat* img, fastdeploy::vision::OCRResult* result);
 | ||
| > ```
 | ||
| >
 | ||
| > 模型预测接口,输入一张图片,返回OCR预测结果
 | ||
| >

| 
 | ||
| ## DBDetector C++接口
 | ||
| 
 | ||
| ### DBDetector类
 | ||
| 
 | ||
| ```
 | ||
| fastdeploy::vision::ocr::DBDetector(const std::string& model_file, const std::string& params_file = "",
 | ||
|              const RuntimeOption& custom_option = RuntimeOption(),
 | ||
|              const ModelFormat& model_format = ModelFormat::PADDLE);
 | ||
| ```
 | ||
| 
 | ||
| DBDetector模型加载和初始化,其中模型为paddle模型格式。
 | ||
| 
 | ||
| **参数**
 | ||
| 
 | ||
| > * **model_file**(str): 模型文件路径
 | ||
| > * **params_file**(str): 参数文件路径,当模型格式为ONNX时,此参数传入空字符串即可
 | ||
| > * **runtime_option**(RuntimeOption): 后端推理配置,默认为None,即采用默认配置
 | ||
| > * **model_format**(ModelFormat): 模型格式,默认为Paddle格式
 | ||
| 
 | ||
| ### Classifier类与DBDetector类相同
 | ||
| 
 | ||
| ### Recognizer类
 | ||
| ```
 | ||
|   Recognizer(const std::string& model_file,
 | ||
|              const std::string& params_file = "",
 | ||
|              const std::string& label_path = "",

|              const RuntimeOption& custom_option = RuntimeOption(),
 | ||
|              const ModelFormat& model_format = ModelFormat::PADDLE);
 | ||
| ```
 | ||
| Recognizer类初始化时,需要在label_path参数中,输入识别模型所需的label文件,其他参数均与DBDetector类相同
 | ||
| 
 | ||
| **参数**
 | ||
| > * **label_path**(str): 识别模型的label文件路径
 | ||
| 
 | ||
| 
 | ||
| ### 类成员变量
 | ||
| #### DBDetector预处理参数
 | ||
| 用户可按照自己的实际需求,修改下列预处理参数,从而影响最终的推理和部署效果
 | ||
| 
 | ||
| > > * **max_side_len**(int): 检测算法前向时图片长边的最大尺寸,当长边超出这个值时会将长边resize到这个大小,短边等比例缩放,默认为960
 | ||
| > > * **det_db_thresh**(double): DB模型输出预测图的二值化阈值,默认为0.3
 | ||
| > > * **det_db_box_thresh**(double): DB模型输出框的阈值,低于此值的预测框会被丢弃,默认为0.6

| #### Classifier预处理参数
 | ||
| 用户可按照自己的实际需求,修改下列预处理参数,从而影响最终的推理和部署效果
