|
||||
|
||||
### 解决方案
|
||||
|
||||
```bash

将paddleocr里面的字体放到系统字体路径下,例如:
|
||||
|
||||
```bash
|
||||
cp /workspace/PaddleOCR-3.1.0/doc/fonts/simfang.ttf /usr/share/fonts/
|

||||
|
||||
# 1. 介绍
|
||||
|
||||
PaddleX 3.0 是基于飞桨框架构建的低代码开发工具,它集成了众多**开箱即用的预训练模型**,可以实现模型从训练到推理的**全流程开发**,支持国内外**多款主流硬件**,助力AI 开发者进行产业实践。
|
||||
|
||||
作用:
|
||||
|
||||
- 部署服务端,方便客户端调用
|
||||
|
||||
|
||||
|
||||
# 2. 安装
|
||||
|
||||
注意:安装 PaddleX 前需要安装 PaddlePaddle
|
||||
|
||||
## 2.1 安装 PaddlePaddle
|
||||
|
||||
```bash
|
||||
# CPU 版本
|
||||
python -m pip install paddlepaddle==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/
|
||||
|
||||
# GPU 版本,需显卡驱动程序版本 ≥450.80.02(Linux)或 ≥452.39(Windows)(当前使用的是这个版本测试的)
|
||||
python -m pip install paddlepaddle-gpu==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
|
||||
|
||||
# GPU 版本,需显卡驱动程序版本 ≥550.54.14(Linux)或 ≥550.54.14(Windows)
|
||||
python -m pip install paddlepaddle-gpu==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu126/
|
||||
```
|
||||
|
||||
> ❗无需关注物理机上的 CUDA 版本,只需关注显卡驱动程序版本。更多飞桨 Wheel 版本信息,请参考[飞桨官网](https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation./docs/zh/install/pip/linux-pip.html)。
|
||||
|
||||
## 2.2 安装 PaddleX
|
||||
|
||||
### 2.2.1 命令行安装
|
||||
|
||||
```bash
|
||||
pip install "paddlex[base]"
|
||||
```
|
||||
|
||||
|
||||
|
||||
# 3. 使用
|
||||
|
||||
## 3.1 部署项目
|
||||
|
||||
> 参考文档:https://paddlepaddle.github.io/PaddleX/latest/pipeline_deploy/serving.html#12
|
||||
|
||||
### 3.1.1 安装服务化部署插件
|
||||
|
||||
执行如下命令,安装服务化部署插件:
|
||||
|
||||
```bash
|
||||
paddlex --install serving
|
||||
```
|
||||
|
||||
### 3.1.2 生成配置文件
|
||||
|
||||
使用相关命令,其中 OCR 当前为通用 OCR 产线,需要不同的产线就修改不同的名称即可。
|
||||
|
||||
```bash
|
||||
paddlex --get_pipeline_config OCR --save_path ./OCR.yaml
|
||||
```
|
||||
|
||||
生成成功会提示
|
||||
|
||||
```bash
|
||||
The pipeline config has been saved to: OCR.yaml
|
||||
```
|
||||
|
||||
生成的默认配置如下:
|
||||
|
||||
```yaml
|
||||
pipeline_name: OCR
|
||||
|
||||
text_type: general
|
||||
|
||||
use_doc_preprocessor: True
|
||||
use_textline_orientation: True
|
||||
|
||||
SubPipelines:
|
||||

|
||||

|
||||
unclip_ratio: 1.5
|
||||
TextLineOrientation:
|
||||
module_name: textline_orientation
|
||||
model_name: PP-LCNet_x1_0_textline_ori
|
||||
model_dir: null
|
||||
batch_size: 6
|
||||
TextRecognition:
|
||||
module_name: text_recognition
|
||||
model_name: PP-OCRv5_server_rec
|
||||
model_dir: null
|
||||
batch_size: 6
|
||||
score_thresh: 0.0
|
||||
```
|
||||
|
||||
**修改配置文件**
|
||||
|
||||
注意将训练好的模型路径配置 `./pipeline/rec_inference` 和 `./pipeline/det_inference`
|
||||
|
||||
```yaml
|
||||
# 整体 pipeline 名称,用于识别产线名称
|
||||
pipeline_name: OCR
|
||||
|
||||
# 文本类型,可选 general(通用)或 others,决定一些后处理策略
|
||||
text_type: general
|
||||
|
||||
# 是否使用文档预处理模块(方向分类 + 扭曲矫正)
|
||||
# 如无严重倾斜/扫描件,建议设为 False,可显著提升速度
|
||||
use_doc_preprocessor: False
|
||||
|
||||
# 是否对检测出的文本行进行角度分类(如 0° / 90° / 180°)
|
||||
# mobile 模型一般建议关闭
|
||||
use_textline_orientation: False
|
||||
|
||||
# 正式的 OCR 主流程模块
|
||||
SubModules:
|
||||
|
||||
# 文本检测模块(通常是基于 DB 的检测器)
|
||||
TextDetection:
|
||||
module_name: text_detection
|
||||
model_name: PP-OCRv5_server_det # 使用的是 server 版大模型,精度高但速度慢
|
||||
model_dir: ./pipeline/det_inference # 本地模型文件夹路径(需包含 model.pdmodel 等)
|
||||
limit_side_len: 64 # 输入图最短边 resize 到此尺寸(可适当调大提高效果)
|
||||
limit_type: min
|
||||
max_side_limit: 4000 # 最长边最大不超过此值
|
||||
thresh: 0.3 # 检测 binarize 阈值
|
||||
box_thresh: 0.6 # 文本框置信度阈值
|
||||
unclip_ratio: 1.5 # DB 算法的后处理参数,控制框扩大比例
|
||||
|
||||
# 文本识别模块(通常是 CRNN + CTC 或 SVTR 模型)
|
||||
TextRecognition:
|
||||
module_name: text_recognition
|
||||
model_name: PP-OCRv5_server_rec # 同样使用的是 server 版识别模型
|
||||
model_dir: ./pipeline/rec_inference
|
||||
batch_size: 6 # 一次识别图块的数量,适当调大可提高 GPU 利用率
|
||||
score_thresh: 0.0 # 识别结果置信度下限,低于此不输出
|
||||
```
|
||||
|
||||
### 3.1.3 运行服务器
|
||||
|
||||
通过 PaddleX CLI 运行服务器:
|
||||
|
||||
```bash
|
||||
paddlex --serve --pipeline {产线名称或产线配置文件路径} [{其他命令行选项}]
|
||||
```
|
||||
|
||||
参考命令:
|
||||
|
||||
```bash
|
||||
paddlex --serve --pipeline .\OCR.yaml --device gpu:0 --port 8866
|
||||
```
|
||||
|
||||
可以看到类似以下展示的信息,即代表成功
|
||||
|
||||
```
|
||||
INFO: Started server process [63108]
|
||||
INFO: Waiting for application startup.
|
||||
INFO: Application startup complete.
|
||||
INFO: Uvicorn running on http://0.0.0.0:8080 (Press CTRL+C to quit)
|
||||
```
|
||||
|
||||
### 3.1.4 调用服务
|
||||
|
||||
对于服务提供的主要操作:
|
||||
|
||||
- HTTP请求方法为POST。
|
||||
- 请求体和响应体均为JSON数据(JSON对象)。
|
||||
- 当请求处理成功时,响应状态码为`200`,响应体的属性如下:
|
||||
|
||||
| 名称 | 类型 | 含义 |
|
||||
| :---------- | :-------- | :---------------------------- |
|
||||
| `logId` | `string` | 请求的UUID。 |

# 加载自定义模型
|
||||
|
||||
## 1. 修改 PPOCRLabel.py
|
||||
|
||||
```python
|
||||
params = {
|
||||
"use_doc_orientation_classify": False,
|
||||
"use_doc_unwarping": False,
|
||||
"use_textline_orientation": True,
|
||||
"device": self.gpu,
|
||||
"lang": self.lang,
|
||||
"text_detection_model_name": "PP-OCRv5_mobile_det", # 修改为自己的模型名称
|
||||
"text_recognition_model_name": "PP-OCRv5_mobile_rec", # 修改为自己的模型名称
|
||||
"enable_mkldnn": False,
|
||||
}
|
||||
|
||||
if det_model_dir is not None:
|
||||
params["text_detection_model_dir"] = det_model_dir
|
||||
if rec_model_dir is not None:
|
||||
params["text_recognition_model_dir"] = rec_model_dir
|
||||
if cls_model_dir is not None:
|
||||
params["text_line_orientation_model_dir"] = cls_model_dir
|
||||
|
||||
self.ocr = PaddleOCR(**params)
|
||||
self.text_recognizer = TextRecognition(
|
||||
model_name="PP-OCRv5_mobile_rec", # 修改为自己的模型名称
|
||||
model_dir=rec_model_dir,
|
||||
device=self.gpu,
|
||||
)
|
||||
self.text_detector = TextDetection(
|
||||
model_name="PP-OCRv5_mobile_det", # 修改为自己的模型名称
|
||||
model_dir=det_model_dir,
|
||||
device=self.gpu,
|
||||
)
|
||||
```
|
||||
|
||||
## 修改启动命令
|
||||
|
||||
```bash
|
||||
python PPOCRLabel.py --lang ch --kie True --det_model_dir "模型路径" --rec_model_dir "模型路径"
|
||||
|
||||
# 示例
|
||||
python PPOCRLabel.py --lang ch --kie True --det_model_dir ".\model\det_inference\" --rec_model_dir ".\model\rec_inference\"
|
||||
```
