## 1. 背景介绍
中文表格识别在金融行业有着广泛的应用，如保险理赔、财报分析和信息录入等领域。当前，金融行业的表格识别主要以手动录入为主，开发一种自动表格识别成为丞待解决的问题。
![](https://ai-studio-static-online.cdn.bcebos.com/d1e7780f0c7745ada4be540decefd6288e4d59257d8141f6842682a4c05d28b6)
在金融行业中，表格图像主要有清单类的单元格密集型表格，申请表类的大单元格表格，拍照表格和倾斜表格四种主要形式。
![](https://ai-studio-static-online.cdn.bcebos.com/da82ae8ef8fd479aaa38e1049eb3a681cf020dc108fa458eb3ec79da53b45fd1)

当前的表格识别算法不能很好的处理这些场景下的表格图像。在本例中，我们使用PP-Structurev2最新发布的表格识别模型SLANet来演示如何进行中文表格是识别。同时，为了方便作业流程，我们使用表格属性识别模型对表格图像的属性进行识别，对表格的难易程度进行判断，加快人工进行校对速度。

## 2. 中文表格识别
### 2.1 环境准备
```python
# 下载PaddleOCR代码
! git clone -b dygraph https://gitee.com/paddlepaddle/PaddleOCR
```
```python
# 安装PaddleOCR环境
! pip install -r PaddleOCR/requirements.txt --force-reinstall
! pip install protobuf==3.19
```
### 2.2 准备数据集
本例中使用的数据集采用表格[生成工具](https://github.com/WenmuZhou/TableGeneration)制作。
使用如下命令对数据集进行解压，并查看数据集大小
```python
! cd data/data165849 && tar -xf table_gen_dataset.tar && cd -
! wc -l data/data165849/table_gen_dataset/gt.txt
```
#### 2.2.1 划分训练测试集
使用下述命令将数据集划分为训练集和测试集, 这里将90%划分为训练集，10%划分为测试集
```python
import random
with open('/home/aistudio/data/data165849/table_gen_dataset/gt.txt') as f:
lines = f.readlines()
random.shuffle(lines)
train_len = int(len(lines)*0.9)
train_list = lines[:train_len]
val_list = lines[train_len:]
# 保存结果
with open('/home/aistudio/train.txt','w',encoding='utf-8') as f:
f.writelines(train_list)
with open('/home/aistudio/val.txt','w',encoding='utf-8') as f:
f.writelines(val_list)
```
划分完成后，数据集信息如下
|类型|数量|图片地址|标注文件路径|
|---|---|---|---|
|训练集|18000|/home/aistudio/data/data165849/table_gen_dataset|/home/aistudio/train.txt|
|测试集|2000|/home/aistudio/data/data165849/table_gen_dataset|/home/aistudio/val.txt|
#### 2.2.2 查看数据集
```python
import cv2
import os, json
import numpy as np
from matplotlib import pyplot as plt
%matplotlib inline
def parse_line(data_dir, line):
data_line = line.strip("\n")
info = json.loads(data_line)
file_name = info['filename']
cells = info['html']['cells'].copy()
structure = info['html']['structure']['tokens'].copy()
img_path = os.path.join(data_dir, file_name)
if not os.path.exists(img_path):
print(img_path)
return None
data = {
'img_path': img_path,
'cells': cells,
'structure': structure,
'file_name': file_name
}
return data
def draw_bbox(img_path, points, color=(255, 0, 0), thickness=2):
if isinstance(img_path, str):
img_path = cv2.imread(img_path)
img_path = img_path.copy()
for point in points:
cv2.polylines(img_path, [point.astype(int)], True, color, thickness)
return img_path
def rebuild_html(data):
html_code = data['structure']
cells = data['cells']
to_insert = [i for i, tag in enumerate(html_code) if tag in ('<td>', '>')]
for i, cell in zip(to_insert[::-1], cells[::-1]):
if cell['tokens']:
text = ''.join(cell['tokens'])
# skip empty text
sp_char_list = ['<b>', '</b>', '\u2028', ' ', '<i>', '</i>']
text_remove_style = skip_char(text, sp_char_list)
if len(text_remove_style) == 0:
continue
html_code.insert(i + 1, text)
html_code = ''.join(html_code)
return html_code
def skip_char(text, sp_char_list):
"""
skip empty cell
@param text: text in cell
@param sp_char_list: style char and special code
@return:
"""
for sp_char in sp_char_list:
text = text.replace(sp_char, '')
return text
save_dir = '/home/aistudio/vis'
os.makedirs(save_dir, exist_ok=True)
image_dir = '/home/aistudio/data/data165849/'
html_str = '<table border="1">'
# 解析标注信息并还原html表格
data = parse_line(image_dir, val_list[0])
img = cv2.imread(data['img_path'])
img_name = ''.join(os.path.basename(data['file_name']).split('.')[:-1])
img_save_name = os.path.join(save_dir, img_name)
boxes = [np.array(x['bbox']) for x in data['cells']]
show_img = draw_bbox(data['img_path'], boxes)
cv2.imwrite(img_save_name + '_show.jpg', show_img)
html = rebuild_html(data)
html_str += html
html_str += '</table>'
# 显示标注的html字符串
from IPython.core.display import display, HTML
display(HTML(html_str))
# 显示单元格坐标
plt.figure(figsize=(15,15))
plt.imshow(show_img)
plt.show()
```
### 2.3 训练
这里选用PP-Structurev2中的表格识别模型[SLANet](https://github.com/PaddlePaddle/PaddleOCR/blob/dygraph/configs/table/SLANet.yml)
SLANet是PP-Structurev2全新推出的表格识别模型，相比PP-Structurev1中TableRec-RARE，在速度不变的情况下精度提升4.7%。TEDS提升2%
|算法|Acc|[TEDS(Tree-Edit-Distance-based Similarity)](https://github.com/ibm-aur-nlp/PubTabNet/tree/master/src)|Speed|
| --- | --- | --- | ---|
| EDD<sup>[2]</sup> |x| 88.3% |x|
| TableRec-RARE(ours) | 71.73%| 93.88% |779ms|
| SLANet(ours) | 76.31%| 95.89%|766ms|
进行训练之前先使用如下命令下载预训练模型
```python
# 进入PaddleOCR工作目录
os.chdir('/home/aistudio/PaddleOCR')
# 下载英文预训练模型

```
### 2.8 表格识别
在表格结构模型训练完成后，可结合OCR检测识别模型，对表格内容进行识别。
首先下载PP-OCRv3文字检测识别模型
```python
# 下载PP-OCRv3文本检测识别模型并解压

## 3. 表格属性识别
### 3.1 代码、环境、数据准备
#### 3.1.1 代码准备
首先，我们需要准备训练表格属性的代码，PaddleClas集成了PULC方案，该方案可以快速获得一个在CPU上用时2ms的属性识别模型。PaddleClas代码可以clone下载得到。获取方式如下：
```python
! git clone -b develop https://gitee.com/paddlepaddle/PaddleClas
```
#### 3.1.2 环境准备
其次，我们需要安装训练PaddleClas相关的依赖包
```python
! pip install -r PaddleClas/requirements.txt --force-reinstall
! pip install protobuf==3.20.0
```
#### 3.1.3 数据准备
最后，准备训练数据。在这里，我们一共定义了表格的6个属性，分别是表格来源、表格数量、表格颜色、表格清晰度、表格有无干扰、表格角度。其可视化如下：
![](https://user-images.githubusercontent.com/45199522/190587903-ccdfa6fb-51e8-42de-b08b-a127cb04e304.png)
这里，我们提供了一个表格属性的demo子集，可以快速迭代体验。下载方式如下：
```python
%cd PaddleClas/dataset
!wget https://paddleclas.bj.bcebos.com/data/PULC/table_attribute.tar
!tar -xf table_attribute.tar
%cd ../PaddleClas/dataset
%cd ../
```
### 3.2 表格属性识别训练
表格属性训练整体pipelinie如下：
![](https://user-images.githubusercontent.com/45199522/190599426-3415b38e-e16e-4e68-9253-2ff531b1b5ca.png)
1.训练过程中，图片经过预处理之后，送入到骨干网络之中，骨干网络将抽取表格图片的特征，最终该特征连接输出的FC层，FC层经过Sigmoid激活函数后和真实标签做交叉熵损失函数，优化器通过对该损失函数做梯度下降来更新骨干网络的参数，经过多轮训练后，骨干网络的参数可以对为止图片做很好的预测；
2.推理过程中，图片经过预处理之后，送入到骨干网络之中，骨干网络加载学习好的权重后对该表格图片做出预测，预测的结果为一个6维向量，该向量中的每个元素反映了每个属性对应的概率值，通过对该值进一步卡阈值之后，得到最终的输出，最终的输出描述了该表格的6个属性。
当准备好相关的数据之后，可以一键启动表格属性的训练，训练代码如下：
```python
!python tools/train.py -c ./ppcls/configs/PULC/table_attribute/PPLCNet_x1_0.yaml -o Global.device=cpu -o Global.epochs=10
```
### 3.3 表格属性识别推理和部署
#### 3.3.1 模型转换
当训练好模型之后，需要将模型转换为推理模型进行部署。转换脚本如下：
```python
!python tools/export_model.py -c ppcls/configs/PULC/table_attribute/PPLCNet_x1_0.yaml -o Global.pretrained_model=output/PPLCNet_x1_0/best_model
```
执行以上命令之后，会在当前目录上生成`inference`文件夹，该文件夹中保存了当前精度最高的推理模型。
#### 3.3.2 模型推理
安装推理需要的paddleclas包, 此时需要通过下载安装paddleclas的develop的whl包
```python
!pip install https://paddleclas.bj.bcebos.com/whl/paddleclas-0.0.0-py3-none-any.whl
```
进入`deploy`目录下即可对模型进行推理
```python
%cd deploy/
```
推理命令如下：
```python
!python python/predict_cls.py -c configs/PULC/table_attribute/inference_table_attribute.yaml -o Global.inference_model_dir="../inference" -o Global.infer_imgs="../dataset/table_attribute/Table_val/val_9.jpg"
!python python/predict_cls.py -c configs/PULC/table_attribute/inference_table_attribute.yaml -o Global.inference_model_dir="../inference" -o Global.infer_imgs="../dataset/table_attribute/Table_val/val_3253.jpg"
```
推理的表格图片：
![](https://user-images.githubusercontent.com/45199522/190596141-74f4feda-b082-46d7-908d-b0bd5839b430.png)
预测结果如下：
```
val_9.jpg: {'attributes': ['Scanned', 'Little', 'Black-and-White', 'Clear', 'Without-Obstacles', 'Horizontal'], 'output': [1, 1, 1, 1, 1, 1]}
```
推理的表格图片：
![](https://user-images.githubusercontent.com/45199522/190597086-2e685200-22d0-4042-9e46-f61f24e02e4e.png)
预测结果如下：
```
val_3253.jpg: {'attributes': ['Photo', 'Little', 'Black-and-White', 'Blurry', 'Without-Obstacles', 'Tilted'], 'output': [0, 1, 1, 0, 1, 0]}
```
对比两张图片可以发现，第一张图片比较清晰，表格属性的结果也偏向于比较容易识别，我们可以更相信表格识别的结果，第二张图片比较模糊，且存在倾斜现象，表格识别可能存在错误，需要我们人工进一步校验。通过表格的属性识别能力，可以进一步将“人工”和“智能”很好的结合起来，为表格识别能力的落地的精度提供保障。

# 1. 项目介绍
弯曲文字识别在OCR任务中有着广泛的应用，比如：自然场景下的招牌，艺术文字，以及常见的印章文字识别。
在本项目中，将以印章识别任务为例，介绍如何使用PaddleDetection和PaddleOCR完成印章检测和印章文字识别任务。
项目难点：
1. 缺乏训练数据
2. 图像质量参差不齐，图像模糊，文字不清晰
针对以上问题，本项目选用PaddleOCR里的PPOCRLabel工具完成数据标注。基于PaddleDetection完成印章区域检测，然后通过PaddleOCR里的端对端OCR算法和两阶段OCR算法分别完成印章文字识别任务。不同任务的精度效果如下：
| 任务 | 训练数据数量 | 精度 |
| -------- | - | -------- |
| 印章检测 | 1000 | 95% |
| 印章文字识别-端对端OCR方法 | 700 | 47% |
| 印章文字识别-两阶段OCR方法 | 700 | 55% |

- 打开数据集所在文件夹
- 按下快捷键Q进行4点（多点）标注——针对印章文本识别，
- 印章弯曲文字包围框采用偶数点标注（比如4点，8点，16点），按照阅读顺序，以16点标注为例，从文字左上方开始标注->到文字右上方标注8个点->到文字右下方->文字左下方8个点，一共8个点，形成包围曲线，参考下图。如果文字弯曲程度不高，为了减小标注工作量，可以采用4点、8点标注，需要注意的是，文字上下点数相同。（总点数尽量不要超过18个）
- 对于需要识别的印章中非弯曲文字，采用4点框标注即可
- 对应包围框的文字部分默认是”待识别”，需要修改为包围框内的具体文字内容
- 快捷键W进行矩形标注——针对印章区域检测，印章检测区域保证标注框包围整个印章，包围框对应文字可以设置为'印章区域'，方便后续处理。
- 针对印章中的水平文字可以视情况考虑矩形或四点标注：保证按行标注即可。如果背景文字与印章文字比较接近，标注时尽量避开背景文字。
- 标注完成后修改右侧文本结果，确认无误后点击下方check（或CTRL+V)，确认本张图片的标注。
- 所有图片标注完成后，在顶部菜单栏点击File -> Export Label导出label.txt。
标注完成后，可视化效果如下：

数据标注完成后，标签中包含印章检测的标注和印章文字识别的标注，如下所示：
```
img/1.png [{"transcription": "印章区域", "points": [[87, 245], [214, 245], [214, 369], [87, 369]], "difficult": false}, {"transcription": "国家税务总局泸水市税务局第二税务分局", "points": [[110, 314], [116, 290], [131, 275], [152, 273], [170, 277], [181, 289], [186, 303], [186, 312], [201, 311], [198, 289], [189, 272], [175, 259], [152, 252], [124, 257], [100, 280], [94, 312]], "difficult": false}, {"transcription": "征税专用章", "points": [[117, 334], [183, 334], [183, 352], [117, 352]], "difficult": false}]
```
标注中包含表示'印章区域'的坐标和'印章文字'坐标以及文字内容。
## 3.2 数据处理
标注时为了方便标注，没有区分印章区域的标注框和文字区域的标注框，可以通过python代码完成标签的划分。
在本项目的'/home/aistudio/work/seal_labeled_datas'目录下，存放了标注的数据示例，如下：
![](https://ai-studio-static-online.cdn.bcebos.com/3d762970e2184177a2c633695a31029332a4cd805631430ea797309492e45402)
标签文件'/home/aistudio/work/seal_labeled_datas/Label.txt'中的标注内容如下：
```
img/test1.png [{"transcription": "待识别", "points": [[408, 232], [537, 232], [537, 352], [408, 352]], "difficult": false}, {"transcription": "电子回单", "points": [[437, 305], [504, 305], [504, 322], [437, 322]], "difficult": false}, {"transcription": "云南省农村信用社", "points": [[417, 290], [434, 295], [438, 281], [446, 267], [455, 261], [472, 258], [489, 264], [498, 277], [502, 295], [526, 289], [518, 267], [503, 249], [475, 232], [446, 239], [429, 255], [418, 275]], "difficult": false}, {"transcription": "专用章", "points": [[437, 319], [503, 319], [503, 338], [437, 338]], "difficult": false}]
```
为了方便训练，我们需要通过python代码将用于训练印章检测和训练印章文字识别的标注区分开。

数据处理完成后，转换为VOC格式的印章检测数据存储在~/data/seal_VOC目录下，目录组织结构为：

│   └── valid.txt
├── JPEGImages/
├── train.txt
└── valid.txt

```
Annotations下为数据的标签，JPEGImages目录下为图像文件，label_list.txt为标注检测框类别标签文件。
在接下来一节中，将介绍如何使用PaddleDetection工具库完成印章检测模型的训练。
# 4. 印章检测实践
在实际应用中，印章多是出现在合同，发票，公告等场景中，印章文字识别的任务需要排除图像中背景文字的影响，因此需要先检测出图像中的印章区域。
借助PaddleDetection目标检测库可以很容易的实现印章检测任务，使用PaddleDetection训练印章检测任务流程如下：
- 选择算法
- 修改数据集配置路径
- 启动训练
**算法选择**
PaddleDetection中有许多检测算法可以选择，考虑到每条数据中印章区域较为清晰，且考虑到性能需求。在本项目中，我们采用mobilenetv3为backbone的ppyolo算法完成印章检测任务，对应的配置文件是：configs/ppyolo/ppyolo_mbv3_large.yml
**修改配置文件**
配置文件中的默认数据路径是COCO，
需要修改为印章检测的数据路径，主要修改如下:
在配置文件'configs/ppyolo/ppyolo_mbv3_large.yml'末尾增加如下内容：
```
metric: VOC
map_type: 11point
num_classes: 2
TrainDataset:
!VOCDataSet
dataset_dir: dataset/seal_VOC
anno_path: train.txt
label_list: label_list.txt
data_fields: ['image', 'gt_bbox', 'gt_class', 'difficult']
EvalDataset:
!VOCDataSet
dataset_dir: dataset/seal_VOC
anno_path: test.txt
label_list: label_list.txt
data_fields: ['image', 'gt_bbox', 'gt_class', 'difficult']
TestDataset:
!ImageFolder
anno_path: dataset/seal_VOC/label_list.txt
```
配置文件中设置的数据路径在PaddleDetection/dataset目录下，我们可以将处理后的印章检测训练数据移动到PaddleDetection/dataset目录下或者创建一个软连接。
```
!ln -s seal_VOC ./PaddleDetection/dataset/
```
另外图象中印章数量比较少，可以调整NMS后处理的检测框数量，即keep_top_k，nms_top_k 从100，1000，调整为10，100。在配置文件'configs/ppyolo/ppyolo_mbv3_large.yml'末尾增加如下内容完成后处理参数的调整
```
BBoxPostProcess:
decode:
name: YOLOBox
conf_thresh: 0.005
downsample_ratio: 32
clip_bbox: true
scale_x_y: 1.05
nms:
name: MultiClassNMS
keep_top_k: 10 # 修改前100
nms_threshold: 0.45
nms_top_k: 100 # 修改前1000
score_threshold: 0.005
```
修改完成后，需要在PaddleDetection中增加印章数据的处理代码，即在PaddleDetection/ppdet/data/source/目录下创建seal.py文件，文件中填充如下代码：
```

# 5. 印章文字识别实践
在使用ppyolo检测到印章区域后，接下来借助PaddleOCR里的文字识别能力，完成印章中文字的识别。
PaddleOCR中的OCR算法包含文字检测算法，文字识别算法以及OCR端对端算法。
文字检测算法负责检测到图像中的文字，再由文字识别模型识别出检测到的文字，进而实现OCR的任务。文字检测+文字识别串联完成OCR任务的架构称为两阶段的OCR算法。相对应的端对端的OCR方法可以用一个算法同时完成文字检测和识别的任务。
| 文字检测 | 文字识别 | 端对端算法 |
| -------- | -------- | -------- |
| DB\DB++\EAST\SAST\PSENet | SVTR\CRNN\NRTN\Abinet\SAR\... | PGNet |
本节中将分别介绍端对端的文字检测识别算法以及两阶段的文字检测识别算法在印章检测识别任务上的实践。
## 5.1 端对端印章文字识别实践
本节介绍使用PaddleOCR里的PGNet算法完成印章文字识别。
PGNet属于端对端的文字检测识别算法，在PaddleOCR中的配置文件为：
[PaddleOCR/configs/e2e/e2e_r50_vd_pg.yml](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/configs/e2e/e2e_r50_vd_pg.yml)
使用PGNet完成文字检测识别任务的步骤为：
- 修改配置文件
- 启动训练
PGNet默认配置文件的数据路径为totaltext数据集路径，本次训练中，需要修改为上一节数据处理后得到的标签文件和数据目录：
训练数据配置修改后如下：
```
Train:
dataset:
name: PGDataSet
data_dir: ./train_data/seal_ppocr
label_file_list: [./train_data/seal_ppocr/seal_ppocr_img.txt]
ratio_list: [1.0]
```
测试数据集配置修改后如下：
```
Eval:
dataset:
name: PGDataSet
data_dir: ./train_data/seal_ppocr_test
label_file_list: [./train_data/seal_ppocr_test/seal_ppocr_img.txt]
```
启动训练的命令为:
```
!python3 tools/train.py -c configs/e2e/e2e_r50_vd_pg.yml
```
模型训练完成后，可以得到最终的精度为47.4%。数据量较少，以及数据质量较差会影响模型的训练精度，如果有更多的数据参与训练，精度将进一步提升。

## 5.2 两阶段印章文字识别实践
上一节介绍了使用PGNet实现印章识别任务的训练流程。本小节将介绍使用PaddleOCR里的文字检测和文字识别算法分别完成印章文字的检测和识别。
### 5.2.1 印章文字检测
PaddleOCR中包含丰富的文字检测算法，包含DB，DB++，EAST，SAST，PSENet等等。其中DB，DB++，PSENet均支持弯曲文字检测，本项目中，使用DB++作为印章弯曲文字检测算法。
PaddleOCR中发布的db++文字检测算法模型是英文文本检测模型，因此需要重新训练模型。
修改[DB++配置文件](DB++的默认配置文件位于[configs/det/det_r50_db++_icdar15.yml](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/configs/det/det_r50_db%2B%2B_icdar15.yml)
中的数据路径：
```
Train:
dataset:
name: SimpleDataSet
data_dir: ./train_data/seal_ppocr
label_file_list: [./train_data/seal_ppocr/seal_ppocr_img.txt]
ratio_list: [1.0]
```
测试数据集配置修改后如下：
```
Eval:
dataset:
name: SimpleDataSet
data_dir: ./train_data/seal_ppocr_test
label_file_list: [./train_data/seal_ppocr_test/seal_ppocr_img.txt]
```
启动训练：
```
!python3 tools/train.py -c configs/det/det_r50_db++_icdar15.yml -o Global.epoch_num=100
```
考虑到数据较少，通过Global.epoch_num设置仅训练100个epoch。
模型训练完成后，在测试集上预测的可视化效果如下：

### 5.2.2 印章文字识别
上一节中完成了印章文字的检测模型训练，本节介绍印章文字识别模型的训练。识别模型采用SVTR算法，SVTR算法是IJCAI收录的文字识别算法，SVTR模型具备超轻量高精度的特点。
在启动训练之前，需要准备印章文字识别需要的数据集，需要使用如下代码，将印章中的文字区域剪切出来构建训练集。
```
import cv2
import numpy as np
def get_rotate_crop_image(img, points):
'''
img_height, img_width = img.shape[0:2]
left = int(np.min(points[:, 0]))
right = int(np.max(points[:, 0]))
top = int(np.min(points[:, 1]))
bottom = int(np.max(points[:, 1]))
img_crop = img[top:bottom, left:right, :].copy()
points[:, 0] = points[:, 0] - left
points[:, 1] = points[:, 1] - top
'''
assert len(points) == 4, "shape of points must be 4*2"
img_crop_width = int(
max(
np.linalg.norm(points[0] - points[1]),
np.linalg.norm(points[2] - points[3])))
img_crop_height = int(
max(
np.linalg.norm(points[0] - points[3]),
np.linalg.norm(points[1] - points[2])))
pts_std = np.float32([[0, 0], [img_crop_width, 0],
[img_crop_width, img_crop_height],
[0, img_crop_height]])
M = cv2.getPerspectiveTransform(points, pts_std)
dst_img = cv2.warpPerspective(
img,
M, (img_crop_width, img_crop_height),
borderMode=cv2.BORDER_REPLICATE,
flags=cv2.INTER_CUBIC)
dst_img_height, dst_img_width = dst_img.shape[0:2]
if dst_img_height * 1.0 / dst_img_width >= 1.5:
dst_img = np.rot90(dst_img)
return dst_img
def run(data_dir, label_file, save_dir):
datas = open(label_file, 'r').readlines()
for idx, line in enumerate(datas):
img_path, label = line.strip().split('\t')
img_path = os.path.join(data_dir, img_path)
label = json.loads(label)
src_im = cv2.imread(img_path)
if src_im is None:
continue
for anno in label:
seal_box = anno['seal_box']
txt_boxes = anno['polys']
crop_im = get_rotate_crop_image(src_im, text_boxes)
save_path = os.path.join(save_dir, f'{idx}.png')
if not os.path.exists(save_dir):
os.makedirs(save_dir)
# print(src_im.shape)
cv2.imwrite(save_path, crop_im)
```
数据处理完成后，即可配置训练的配置文件。SVTR配置文件选择[configs/rec/PP-OCRv3/ch_PP-OCRv3_rec.yml](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/configs/rec/PP-OCRv3/ch_PP-OCRv3_rec.yml)
修改SVTR配置文件中的训练数据部分如下：
```
Train:
dataset:
name: SimpleDataSet
data_dir: ./train_data/seal_ppocr_crop/
label_file_list:
- ./train_data/seal_ppocr_crop/train_list.txt
```
修改预测部分配置文件：
```
Train:
dataset:
name: SimpleDataSet
data_dir: ./train_data/seal_ppocr_crop/
label_file_list:
- ./train_data/seal_ppocr_crop_test/train_list.txt
```
启动训练：
```
!python3 tools/train.py -c configs/rec/PP-OCRv3/ch_PP-OCRv3_rec.yml
```
训练完成后可以发现测试集指标达到了61%。
由于数据较少，训练时会发现在训练集上的acc指标远大于测试集上的acc指标，即出现过拟合现象。通过补充数据和一些数据增强可以缓解这个问题。

## 4 . 项目实践
AIStudio项目链接：[快速构建卡证类OCR](https://aistudio.baidu.com/aistudio/projectdetail/4459116)
### 4.1 环境准备
1）拉取[paddleocr](https://github.com/PaddlePaddle/PaddleOCR)项目，如果从github上拉取速度慢可以选择从gitee上获取。
```
!git clone https://github.com/PaddlePaddle/PaddleOCR.git -b release/2.6 /home/aistudio/work/
```
2）获取并解压预训练模型，如果要使用其他模型可以从模型库里自主选择合适模型。
```

!tar -vxf /home/aistudio/work/pre_trained/ch_PP-OCRv3_det_distill_train.tar -C /home/aistudio/work/pre_trained
```
3） 安装必要依赖
```
!pip install -r /home/aistudio/work/requirements.txt
```
### 4.2 配置文件修改
修改配置文件 *work/configs/det/detmv3db.yml*
具体修改说明如下：

### 4.3 代码修改
#### 4.3.1 数据读取
* 修改 PaddleOCR/ppocr/data/imaug/label_ops.py中的DetLabelEncode
```python
class DetLabelEncode(object):
# 修改检测标签的编码处，新增了参数分类数：num_classes，重写初始化方法，以及分类标签的读取
def __init__(self, label_list, num_classes=8, **kwargs):
self.num_classes = num_classes
self.label_list = []
if label_list:
if isinstance(label_list, str):
with open(label_list, 'r+', encoding='utf-8') as f:
for line in f.readlines():
self.label_list.append(line.replace("\n", ""))
else:
self.label_list = label_list
else:

* 修改 PaddleOCR/ppocr/data/imaug/make_shrink_map.py中的MakeShrinkMap类。这里需要注意的是，如果我们设置的label_list中的第一个参数为要检测的信息那么会得到如下的mask,
举例说明：
这是检测的mask图，图中有四个mask那么实际对应的分类应该是4类

label_list中第一个为关键分类，则得到的分类Mask实际如下，与上图相比，少了一个box：

在完成上述步骤后我们就可以正常启动训练
```
!python /home/aistudio/work/PaddleOCR/tools/train.py -c /home/aistudio/work/PaddleOCR/configs/det/det_mv3_db.yml
```
其他命令：
```
!python /home/aistudio/work/PaddleOCR/tools/eval.py -c /home/aistudio/work/PaddleOCR/configs/det/det_mv3_db.yml
!python /home/aistudio/work/PaddleOCR/tools/infer_det.py -c /home/aistudio/work/PaddleOCR/configs/det/det_mv3_db.yml
```
模型推理
```
!python /home/aistudio/work/PaddleOCR/tools/infer/predict_det.py --image_dir="/home/aistudio/work/test_img/" --det_model_dir="/home/aistudio/work/PaddleOCR/output/infer"
```
## 5 总结
1. 分类+检测在一定程度上能够缩短用时，具体的模型选取要根据业务场景恰当选择。
2. 数据标注需要多次进行测试调整标注方法，一般进行检测模型微调，需要标注至少上百张。
3. 设置合理的batch_size以及resize大小，同时注意lr设置。

# 金融智能核验：扫描合同关键信息抽取
本案例将使用OCR技术和通用信息抽取技术，实现合同关键信息审核和比对。通过本章的学习，你可以快速掌握：
1. 使用PaddleOCR提取扫描文本内容
2. 使用PaddleNLP抽取自定义信息
点击进入 [AI Studio 项目](https://aistudio.baidu.com/aistudio/projectdetail/4545772)
## 1. 项目背景
合同审核广泛应用于大中型企业、上市公司、证券、基金公司中，是规避风险的重要任务。
- 合同内容对比：合同审核场景中，快速找出不同版本合同修改区域、版本差异；如合同盖章归档场景中有效识别实际签署的纸质合同、电子版合同差异。
- 合规性检查：法务人员进行合同审核，如合同完备性检查、大小写金额检查、签约主体一致性检查、双方权利和义务对等性分析等。
- 风险点识别：通过合同审核可识别事实倾向型风险点和数值计算型风险点等，例如交付地点约定不明、合同总价款不一致、重要条款缺失等风险点。

## 2. 解决方案
### 2.1 扫描合同文本内容提取
使用PaddleOCR开源的模型可以快速完成扫描文档的文本内容提取，在清晰文档上识别准确率可达到95%+。下面来快速体验一下：
#### 2.1.1 环境准备
[PaddleOCR](https://github.com/PaddlePaddle/PaddleOCR)提供了适用于通用场景的高精轻量模型，提供数据预处理-模型推理-后处理全流程，支持pip安装：
```
python -m pip install paddleocr
```
#### 2.1.2 效果测试
使用一张合同图片作为测试样本，感受ppocrv3模型效果：
<img src=https://ai-studio-static-online.cdn.bcebos.com/46258d0dc9dc40bab3ea0e70434e4a905646df8a647f4c49921e217de5142def width=300>
使用中文检测+识别模型提取文本，实例化PaddleOCR类：
```
from paddleocr import PaddleOCR, draw_ocr
# paddleocr目前支持中英文、英文、法语、德语、韩语、日语等80个语种，可以通过修改lang参数进行切换
ocr = PaddleOCR(use_angle_cls=False, lang="ch") # need to run only once to download and load model into memory
```
一行命令启动预测，预测结果包括`检测框`和`文本识别内容`:
```
img_path = "./test_img/hetong2.jpg"
result = ocr.ocr(img_path, cls=False)
for line in result:
print(line)
# 可视化结果
from PIL import Image
image = Image.open(img_path).convert('RGB')
boxes = [line[0] for line in result]
txts = [line[1][0] for line in result]
scores = [line[1][1] for line in result]
im_show = draw_ocr(image, boxes, txts, scores, font_path='./simfang.ttf')
im_show = Image.fromarray(im_show)
im_show.show()
```
#### 2.1.3 图片预处理
通过上图可视化结果可以看到，印章部分造成的文本遮盖，影响了文本识别结果，因此可以考虑通道提取，去除图片中的红色印章：
```
import cv2
import numpy as np
import matplotlib.pyplot as plt
#读入图像,三通道
image=cv2.imread("./test_img/hetong2.jpg",cv2.IMREAD_COLOR) #timg.jpeg
#获得三个通道
Bch,Gch,Rch=cv2.split(image)
#保存三通道图片
cv2.imwrite('blue_channel.jpg',Bch)
cv2.imwrite('green_channel.jpg',Gch)
cv2.imwrite('red_channel.jpg',Rch)
```
#### 2.1.4 合同文本信息提取
经过2.1.3的预处理后，合同照片的红色通道被分离，获得了一张相对更干净的图片，此时可以再次使用ppocr模型提取文本内容：
```
import numpy as np
import cv2
img_path = './red_channel.jpg'
result = ocr.ocr(img_path, cls=False)
# 可视化结果
from PIL import Image
image = Image.open(img_path).convert('RGB')
boxes = [line[0] for line in result]
txts = [line[1][0] for line in result]
scores = [line[1][1] for line in result]
im_show = draw_ocr(image, boxes, txts, scores, font_path='./simfang.ttf')
im_show = Image.fromarray(im_show)
vis = np.array(im_show)
im_show.show()
```
忽略检测框内容，提取完整的合同文本：
```
txts = [line[1][0] for line in result]
all_context = "\n".join(txts)
print(all_context)
```
通过以上环节就完成了扫描合同关键信息抽取的第一步：文本内容提取，接下来可以基于识别出的文本内容抽取关键信息
### 2.2 合同关键信息抽取
#### 2.2.1 环境准备
安装PaddleNLP
```
pip install --upgrade pip
pip install --upgrade paddlenlp
```
#### 2.2.2 合同关键信息抽取
PaddleNLP 使用 Taskflow 统一管理多场景任务的预测功能，其中`information_extraction` 通过大量的有标签样本进行训练，在通用的场景中一般可以直接使用，只需更换关键字即可。例如在合同信息抽取中，我们重新定义抽取关键字：
甲方、乙方、币种、金额、付款方式
将使用OCR提取好的文本作为输入，使用三行命令可以对上文中提取到的合同文本进行关键信息抽取：
```
from paddlenlp import Taskflow
schema = ["甲方","乙方","总价"]
ie = Taskflow('information_extraction', schema=schema)
ie.set_schema(schema)
ie(all_context)
```
可以看到UIE模型可以准确的提取出关键信息，用于后续的信息比对或审核。
## 3.效果优化
### 3.1 文本识别后处理调优
实际图片采集过程中，可能出现部分图片弯曲等问题，导致使用默认参数识别文本时存在漏检，影响关键信息获取。
例如下图:
<img src="https://ai-studio-static-online.cdn.bcebos.com/fe350481be0241c58736d487d1bf06c2e65911bf01254a79944be629c4c10091" height="300" width="300">
直接进行预测：
```
img_path = "./test_img/hetong3.jpg"
# 预测结果
result = ocr.ocr(img_path, cls=False)
# 可视化结果
from PIL import Image
image = Image.open(img_path).convert('RGB')
boxes = [line[0] for line in result]
txts = [line[1][0] for line in result]
scores = [line[1][1] for line in result]
im_show = draw_ocr(image, boxes, txts, scores, font_path='./simfang.ttf')
im_show = Image.fromarray(im_show)
im_show.show()
```
可视化结果可以看到，弯曲图片存在漏检，一般来说可以通过调整后处理参数解决，无需重新训练模型。漏检问题往往是因为检测模型获得的分割图太小，生成框的得分过低被过滤掉了，通常有两种方式调整参数：
- 开启`use_dilatiion=True` 膨胀分割区域
- 调小`det_db_box_thresh`阈值
```
# 重新实例化 PaddleOCR
ocr = PaddleOCR(use_angle_cls=False, lang="ch", det_db_box_thresh=0.3, use_dilation=True)
# 预测并可视化
img_path = "./test_img/hetong3.jpg"
# 预测结果
result = ocr.ocr(img_path, cls=False)
# 可视化结果
image = Image.open(img_path).convert('RGB')
boxes = [line[0] for line in result]
txts = [line[1][0] for line in result]
scores = [line[1][1] for line in result]
im_show = draw_ocr(image, boxes, txts, scores, font_path='./simfang.ttf')
im_show = Image.fromarray(im_show)
im_show.show()
```
可以看到漏检问题被很好的解决，提取完整的文本内容：
```
txts = [line[1][0] for line in result]
context = "\n".join(txts)
print(context)
```
### 3.2 关键信息提取调优
UIE通过大量有标签样本进行训练，得到了一个开箱即用的高精模型。 然而针对不同场景，可能会出现部分实体无法被抽取的情况。通常来说有以下几个方法进行效果调优：
- 修改 schema
- 添加正则方法
- 标注小样本微调模型
**修改schema**
Prompt和原文描述越像，抽取效果越好，例如
```
三：合同价格：总价为人民币大写：参拾玖万捌仟伍佰
元，小写：398500.00元。总价中包括站房工程建设、安装
及相关避雷、消防、接地、电力、材料费、检验费、安全、
验收等所需费用及其他相关费用和税金。
```
schema = ["总金额"] 时无法准确抽取，与原文描述差异较大。 修改 schema = ["总价"] 再次尝试：
```
from paddlenlp import Taskflow
# schema = ["总金额"]
schema = ["总价"]
ie = Taskflow('information_extraction', schema=schema)
ie.set_schema(schema)
ie(all_context)
```
**模型微调**
UIE的建模方式主要是通过 `Prompt` 方式来建模， `Prompt` 在小样本上进行微调效果非常有效。详细的数据标注+模型微调步骤可以参考项目：

## 总结
扫描合同的关键信息提取可以使用 PaddleOCR + PaddleNLP 组合实现，两个工具均有以下优势：
* 使用简单：whl包一键安装，3行命令调用
* 效果领先：优秀的模型效果可覆盖几乎全部的应用场景
* 调优成本低：OCR模型可通过后处理参数的调整适配略有偏差的扫描文本， UIE模型可以通过极少的标注样本微调，成本很低。

Layout analysis refers to the regional division of documents in the form of pictures and the positioning of key areas, such as text, title, table, picture, etc. The layout analysis algorithm is based on the lightweight model PP-picodet of [PaddleDetection]( https://github.com/PaddlePaddle/PaddleDetection )
Layout analysis refers to the regional division of documents in the form of pictures and the positioning of key areas, such as text, title, table, picture, etc. The layout analysis algorithm is based on the lightweight model PP-picodet of [PaddleDetection]( https://github.com/PaddlePaddle/PaddleDetection ), including English layout analysis, Chinese layout analysis and table layout analysis models. English layout analysis models can detect document layout elements such as text, title, table, figure, list. Chinese layout analysis models can detect document layout elements such as text, figure, figure caption, table, table caption, header, footer, reference, and equation. Table layout analysis models can detect table regions.
