# PP-OCRv3 SOPHGO C++部署示例
|
|
|
|
|
|
本目录下提供`infer.cc`快速完成PPOCRv3模型在SOPHGO BM1684x板子上加速部署的示例。
|
|
|
|
|
|
|
|
|
|
|
|
## 1. 部署环境准备
|
|
|
|
|
|
在部署前，需自行编译基于SOPHGO硬件的预测库，参考文档[SOPHGO硬件部署环境](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install#算能硬件部署环境)
|
|
|
|
|
|
|
|
|
|
|
|
## 2. 生成基本目录文件
|
|
|
|
|
|
|
|
|
|
|
|
该例程由以下几个部分组成
|
|
|
|
|
|
```text
|
|
|
|
|
|
.
|
|
|
|
|
|
├── CMakeLists.txt
|
|
|
|
|
|
├── fastdeploy-sophgo # 编译好的SDK文件夹
|
|
|
|
|
|
├── image # 存放图片的文件夹
|
|
|
|
|
|
├── infer.cc
|
|
|
|
|
|
└── model # 存放模型文件的文件夹
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## 3.部署示例
|
|
|
|
|
|
|
|
|
|
|
|
### 3.1 下载部署示例代码
|
|
|
|
|
|
```bash
|
|
|
|
|
|
# 下载部署示例代码
|
|
|
|
|
|
git clone https://github.com/PaddlePaddle/FastDeploy.git
|
|
|
|
|
|
cd FastDeploy/examples/vision/ocr/PP-OCR/sophgo/cpp
|
|
|
|
|
|
|
|
|
|
|
|
# 如果您希望从PaddleOCR下载示例代码，请运行
|
|
|
|
|
|
git clone https://github.com/PaddlePaddle/PaddleOCR.git
|
|
|
|
|
|
# 注意：如果当前分支找不到下面的fastdeploy测试代码，请切换到dygraph分支
|
|
|
|
|
|
git checkout dygraph
|
|
|
|
|
|
cd PaddleOCR/deploy/fastdeploy/sophgo/cpp
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
### 3.2 拷贝bmodel模型文至model文件夹
|
|
|
|
|
|
将Paddle模型转换为SOPHGO bmodel模型，转换步骤参考[文档](../README.md). 将转换后的SOPHGO bmodel模型文件拷贝至model中.
|
|
|
|
|
|
|
|
|
|
|
|
### 3.3 准备测试图片至image文件夹，以及字典文件
|
|
|
|
|
|
```bash
|
|
|
|
|
|
wget https://gitee.com/paddlepaddle/PaddleOCR/raw/release/2.6/doc/imgs/12.jpg
|
|
|
|
|
|
cp 12.jpg image/
|
|
|
|
|
|
|
|
|
|
|
|
wget https://gitee.com/paddlepaddle/PaddleOCR/raw/release/2.6/ppocr/utils/ppocr_keys_v1.txt
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
### 3.4 编译example
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
cd build
|
|
|
|
|
|
cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-0.0.3
|
|
|
|
|
|
make
|
|
|
|
|
|
```
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
./infer_demo model ./ppocr_keys_v1.txt image/12.jpeg
|
|
|
|
|
|
```
