										 |  |  |  | 本章节介绍PaddleOCR 模型的C++部署方法。C++在性能计算上优于Python,因此,在大多数CPU、GPU部署场景,多采用C++的部署方式,本节将介绍如何在Linux\Windows (CPU\GPU)环境下配置C++环境并完成PaddleOCR模型部署。 |

							|  |  |  |  | - Linux环境,推荐使用docker。 | 
					
						
							|  |  |  |  | - Windows环境。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | * 该文档主要介绍基于Linux环境的PaddleOCR C++预测流程,如果需要在Windows下基于预测库进行C++预测,具体编译方法请参考[Windows下编译教程](./docs/windows_vs2019_build.md) |

										 |  |  |  | ### 1.2 编译opencv库
 | 
					
						
							| 
									
										
										
										
											2022-04-21 05:24:31 +00:00
										 |  |  |  | 
 | 
					
						
							|  |  |  |  | * 首先需要从opencv官网上下载在Linux环境下源码编译的包,以opencv3.4.7为例,下载命令如下。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | ```bash | 
					
						
							|  |  |  |  | cd deploy/cpp_infer | 
					
						
							|  |  |  |  | wget https://paddleocr.bj.bcebos.com/libs/opencv/opencv-3.4.7.tar.gz | 
					
						
							|  |  |  |  | tar -xf opencv-3.4.7.tar.gz | 
					
						
							|  |  |  |  | ``` | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 最终可以在当前目录下看到`opencv-3.4.7/`的文件夹。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | * 编译opencv,设置opencv源码路径(`root_path`)以及安装路径(`install_path`)。进入opencv源码路径下,按照下面的方式进行编译。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | ```shell | 
					
						
							|  |  |  |  | root_path="your_opencv_root_path" | 
					
						
							|  |  |  |  | install_path=${root_path}/opencv3 | 
					
						
							|  |  |  |  | build_dir=${root_path}/build | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | rm -rf ${build_dir} | 
					
						
							|  |  |  |  | mkdir ${build_dir} | 
					
						
							|  |  |  |  | cd ${build_dir} | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | cmake .. \ | 
					
						
							|  |  |  |  |     -DCMAKE_INSTALL_PREFIX=${install_path} \ | 
					
						
							|  |  |  |  |     -DCMAKE_BUILD_TYPE=Release \ | 
					
						
							|  |  |  |  |     -DBUILD_SHARED_LIBS=OFF \ | 
					
						
							|  |  |  |  |     -DWITH_IPP=OFF \ | 
					
						
							|  |  |  |  |     -DBUILD_IPP_IW=OFF \ | 
					
						
							|  |  |  |  |     -DWITH_LAPACK=OFF \ | 
					
						
							|  |  |  |  |     -DWITH_EIGEN=OFF \ | 
					
						
							|  |  |  |  |     -DCMAKE_INSTALL_LIBDIR=lib64 \ | 
					
						
							|  |  |  |  |     -DWITH_ZLIB=ON \ | 
					
						
							|  |  |  |  |     -DBUILD_ZLIB=ON \ | 
					
						
							|  |  |  |  |     -DWITH_JPEG=ON \ | 
					
						
							|  |  |  |  |     -DBUILD_JPEG=ON \ | 
					
						
							|  |  |  |  |     -DWITH_PNG=ON \ | 
					
						
							|  |  |  |  |     -DBUILD_PNG=ON \ | 
					
						
							|  |  |  |  |     -DWITH_TIFF=ON \ | 
					
						
							|  |  |  |  |     -DBUILD_TIFF=ON | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | make -j | 
					
						
							|  |  |  |  | make install | 
					
						
							|  |  |  |  | ``` | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 也可以直接修改`tools/build_opencv.sh`的内容,然后直接运行下面的命令进行编译。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | ```shell | 
					
						
							|  |  |  |  | sh tools/build_opencv.sh | 
					
						
							|  |  |  |  | ``` | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 其中`root_path`为下载的opencv源码路径,`install_path`为opencv的安装路径,`make install`完成之后,会在该文件夹下生成opencv头文件和库文件,用于后面的OCR代码编译。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 最终在安装路径下的文件结构如下所示。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | ``` | 
					
						
							|  |  |  |  | opencv3/ | 
					
						
							|  |  |  |  | |-- bin | 
					
						
							|  |  |  |  | |-- include | 
					
						
							|  |  |  |  | |-- lib | 
					
						
							|  |  |  |  | |-- lib64 | 
					
						
							|  |  |  |  | |-- share | 
					
						
							|  |  |  |  | ``` |

										 |  |  |  | [Paddle预测库官网](https://paddleinference.paddlepaddle.org.cn/user_guides/download_lib.html#linux) 上提供了不同cuda版本的Linux预测库,可以在官网查看并选择合适的预测库版本(*建议选择paddle版本>=2.0.1版本的预测库* )。 |

							|  |  |  |  | ``` | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 最终会在当前的文件夹中生成`paddle_inference/`的子文件夹。 |

							|  |  |  |  | #### 1.3.2 预测库源码编译
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 如果希望获取最新预测库特性,可以从github上克隆最新Paddle代码进行编译,生成最新的预测库。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | * 使用git获取代码: | 
					
						
							| 
									
										
										
										
											2022-04-21 05:24:31 +00:00
										 |  |  |  | 
 |

							|  |  |  |  | git clone https://github.com/PaddlePaddle/Paddle.git | 
					
						
							|  |  |  |  | git checkout develop |

 | 
					
						
							| 
									
										
										
										
											2022-04-25 12:50:14 +00:00
										 |  |  |  | * 进入Paddle目录,进行编译: | 
					
						
							| 
									
										
										
										
											2022-04-21 05:24:31 +00:00
										 |  |  |  | 
 |

							|  |  |  |  | rm -rf build | 
					
						
							|  |  |  |  | mkdir build | 
					
						
							|  |  |  |  | cd build |

							|  |  |  |  | * 编译完成之后,可以在`build/paddle_inference_install_dir/`文件下看到生成了以下文件及文件夹。 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | ``` |

							|  |  |  |  | ``` | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 其中`paddle`就是C++预测所需的Paddle库,`version.txt`中包含当前预测库的版本信息。 |

											2022-04-25 12:50:14 +00:00
										 |  |  |  | 编译命令如下,其中Paddle C++预测库、opencv等其他依赖库的地址需要换成自己机器上的实际地址。 | 
					
						
							| 
									
										
										
										
											2022-04-21 05:24:31 +00:00
										 |  |  |  |

							|  |  |  |  | 
 | 
					
						
							| 
									
										
										
										
											2022-04-25 12:50:14 +00:00
										 |  |  |  | 具体的,需要修改`tools/build.sh`中环境路径,相关内容如下: | 
					
						
							| 
									
										
										
										
											2022-04-21 05:24:31 +00:00
										 |  |  |  | 
 |

							|  |  |  |  | OPENCV_DIR=your_opencv_dir | 
					
						
							|  |  |  |  | LIB_DIR=your_paddle_inference_dir |

							|  |  |  |  | CUDNN_LIB_DIR=/your_cudnn_lib_dir | 
					
						
							|  |  |  |  | ``` | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 其中,`OPENCV_DIR`为opencv编译安装的地址;`LIB_DIR`为下载(`paddle_inference`文件夹)或者编译生成的Paddle预测库地址(`build/paddle_inference_install_dir`文件夹);`CUDA_LIB_DIR`为cuda库文件地址,在docker中为`/usr/local/cuda/lib64`;`CUDNN_LIB_DIR`为cudnn库文件地址,在docker中为`/usr/lib/x86_64-linux-gnu/`。**注意:以上路径都写绝对路径,不要写相对路径。** |

 | 
					
						
							|
