OCR application: python development form batch recognition small application records

Because tens of thousands of documents need batch OCR input into excel, it is necessary to “agile develop” a batch OCR program. In this context, it is planned to complete the development and use of the exe program in 10 days. Time is tight and the task is heavy, but fortunately it has been completed.

Selection of OCR model

In the case of tight time and heavy tasks, the existing production-level model is the focus of consideration, mainly looking at the OCR model with relatively high github ranking. The first one is paddleocr, which is one of the open source OCR models of Paddle. For further understanding, Paddle and industrial OCR such as paddlehub can be used. For the stability of the OCR program, I first tried the OCR module of paddlehub. As a result, the OCR of the hub will recognize the vertical line between cells as “1” or “|” when recognizing the table. This is only one of the problems; The other is that the newline text in the same cell can not be recognized as a whole, and multiple lines are divided into different string ones, which leads to the increase of work complexity in the later excel classification.

Had to abandon paddlehub and experiment with paddleocr instead. The result is surprisingly good. It can also jointly recognize adjacent cell strings like strings 身份证号码|xxxxxxxxxxxxxx, and without recording vertical lines into strings, different string lengths in the same cell can also be jointly recognized as a single string. This is very surprised, the same company’s products, how to identify the effect of such a big difference..

Construct the recognition function

This part is simple, because the model is ready-made, you can set the required parameters according to the requirements.

from paddleocr import PaddleOCR
import time, os, csv

def recognize_ocr(input):
    ocr = PaddleOCR(use_angle_cls=True, lang="ch") 
    result = ocr.ocr(input, cls=True)
    return result

The result returned is that each string list is saved with the coordinates on the graph where the string is located. The key point of information classification lies in the use of coordinates on the map.

Paddleocr identifies the list that is returned later

Construct information classification function

First, create a CSV file to save, define the header in advance, and an empty dictionary to store the classified information:

dic = {'申请表编号': None,  '填表日期': None, '法定代表人': None, '通信地址': None, \
        '座落': None, '小地名': None, '林地所有权权利人': None, '林种': None, '造林年度': None,\
            '主要树种': None, '林地使用期': None, '面积': None, '登记类型': None, '登记权利内容': None, \
                '身份证编号': None, '单位（个人）': None, '终止日期': None, \
                '东至': None, '南至': None,'西至': None,'北至': None, '申请表文件地址': None, '林权证编号': None,  '宗地图文件地址': None}
header = list(dic.keys())

with open(save_csv_path,"a", newline='') as csvfile: # 
    writer = csv.DictWriter(csvfile, fieldnames=header) 
    writer.writeheader()  # 写入列名
    # writer.writerow([])
    valuelist = {}

Then it is recommended to use the artifact os.walk() of the OS package. The walk function is very powerful. It can search all folders and files under the specified path, and then classify them according to the naming rules:

for root, dirs, files in os.walk(filepath):           
    for file in files:
        split1= file.split('.')
        if split1[-1].lower()=='jpg' and split1[0][-1]=='2': # 
            print("第",n ,"张处理")
            n+=1
            jpgfile = os.path.join(root, file)
            result1 = recognize_ocr(jpgfile)
            for k in range(len(result1)):
                if result1[k][1][0][0:7]=="林权登记申请表":
                    valuelist["申请表文件地址"] = os.path.join(root, file)
                    for i in range(len(result1)):
                        downleft = result1[i][0][0]
                        downright = result1[i][0][1]
                        topright = result1[i][0][2]
                        topleft = result1[i][0][3]
                        if result1[i][1][0][0:5]=="中请表编号" or result1[i][1][0][0:5]=="申请表编号":#
                            if len(result1[i][1][0]) > 7 :
                                valuelist["申请表编号"] = result1[i][1][0][6:]
                                for j in range(len(result1)):
                                    premise_right_center = (topright[1] - downright[1])/2
                                    refer_downleft = result1[j][0][0]
                                    refer_downright = result1[j][0][1]
                                    refer_topright = result1[j][0][2]
                                    refer_topleft = result1[j][0][3]
                                    refer_right_premise = (topright[0] - topleft[0])
                                    if (refer_downleft[1])<(downright[1] + premise_right_center)<refer_topleft[1] and\
                                        topright[0]<(refer_topleft[0]+refer_right_premise/2)<(topright[0]+refer_right_premise):
                                        valuelist["申请表编号"] = result1[j][1][0]

The above code uses the coordinate positioning mentioned above. According to the positioning information, it can be classified into the dictionary. This discrimination is based on the content information of the table you want to identify. I have made more than ten discriminations here, that is, there will be more than ten columns on the final CSV. Each discrimination is basically the same, fine-tuned according to the offset of the identified content.

多个判别式

Finally, add a line of code written into CSV under if to determine whether it is JPG:

writer.writerow(valuelist)

The overall structure is here: 代码结构

In fact, up to this step, the batch identification document function is built, here I cut a paragraph into the following, water the length of the article.

Programming interface based on PySimple Gui

This GUI package is very friendly to people who have difficulty writing interfaces. I spent a lot of time studying Pyqt5 it before, but because the open source protocol and development process of this package are too complex, I abandoned it. Originally, I wanted to ask my colleagues to help me write an interface in C + +, but then I happened to see this GUI package and was shocked. It’s really friendly to my kind of chicken.

I will not repeat the simlegui specific document here. The parameters of the whole OCR function are only CSV文件的路径 and 需要处理的文件所在文件夹地址, so the and input method is mainly used text, and the folder is used FolderBrowse. The file selects the usage FileBrowse method, and the layout of the overall gui layout is as follows:

    [sg.Text('选择的文件/文件夹是:',font=("宋体", 15)), \
        
        sg.Text('None',key='text1',size=(40,1),font=("宋体", 10)),\
            
            sg.FolderBrowse('打开文件夹', key='folder',\
                target='text1', font=("宋体", 15)),\
                    sg.FileBrowse('打开文件', key='sfile', target='text1', font=("宋体", 15))],
    
    
    
    [sg.Text('CSV保存路径:',font=("宋体", 15)), sg.Input('创建csv文件', font=("宋体", 13), key='csv')],
    
    
    [sg.Text('输入图片尾数（规则识别可选）:', font=("宋体", 15)), \
        sg.Input('输入图片全名，如“IMG_0003.jpg”', font=("宋体", 13), key='imgname', size=(30, 1))],
    
    
    [sg.Text('程序运行记录',justification='center')],
    [sg.Output(size=(110, 20),font=("宋体", 10))],
    [sg.Button('规则批量识别'), sg.Button('无差别识别'), sg.Button('单张识别')]
    
    ]    
window = sg.Window('林权识别', layout, font=("宋体", 15), default_element_size=(50,1))

The operation of simplegui takes infinite loop as the operation logic, and executes different functions by judging the key obtained values.

    if event == '规则批量识别':
        if values['folder']:

                print("开始规则识别")
                batchocr(values['folder'], values['csv'], values['imgname'])
            else:
                sg.popup('请输入图片名称')

    if event == '单张识别': 
        if values['sfile']:
            singleocr(values['sfile'], values['csv'])
            print("输出完成")

Here in order to enrich the use of functions, I also created a single image recognition function, more or less the same, with the batch version of the modification. Rule recognition is also added, which is the recognition of fixed names or fixed name rules according to the naming rules specified by Party A.

At this point, most of the work is done, and the overall code is as follows:

The code is super long, isn’t it? The main reason is that there are many discriminants, and although the correct rate of paddle’s model is very high, there are still some recognition flaws. For example, some rare words appear in some rare place names, and it is understandable that paddle can’t recognize them. Here, it is good to use the string replacement after discrimination. Similarly, if there are other problems, do a few more judgments, the actual running time of a document recognition is very fast, about 10 seconds can classify all the information into a picture, so the judgment can save a lot of post-processing time.

QPT packaging

This part is thanks to 大佬 the open source packaging tool for deep learning. QPT has been used as an example of packaging program by paddle official forum. I began to use pyinstaller to package various environmental problems. By qpt, there are only a few small environmental problems left. Although there is nuikta such a powerful package, I am used to using pyinstaller, and the solution I found only saw QPT working. In order to save time, I directly used the existing solution. I suggest readers to look at nuikta when they are free later. My plan is to take a look at this thing later.

On the other hand, in fact, QPT packaging is also very simple. The packaging code has been given very concisely in 示例, and we just need to adjust it according to the requirements.

Here is the code I used for packaging:

from qpt.executor import CreateExecutableModule as CEM
from qpt.modules.python_env import Python38
#                                                
#-----关于路径的部分，强烈建议使用绝对路径避免出现问题-----
module = CEM(work_dir=r"D:\Data\testdata\huizong\dabao",                # [项目文件夹]待打包的目录，并且该目录下需要有↓下方提到的py文件
             launcher_py_path=r"D:\Data\testdata\huizong\dabao\test13.py", # [主程序文件]用户启动EXE文件后，QPT要执行的py文件
             save_path=r"D:\Data\testdata\huizong\dabao",
             requirements_file="auto",
             hidden_terminal=True,
             interpreter_module=Python38()
            )    
module.make()

There are still two problems.

One is that the environment is not fully packaged. The paddleocr Chinese recognition package under the path C:\Users\jerry\.paddleocr\whl is not packaged into the environment by qpt. When configuring under a new computer, the environment still needs to be migrated manually. But this solution is also very simple, using the syntax of the command line to make a .bat file can actually be very easy to solve. But in fact, this tool is developed for our own people to use, I did not do this thing (mainly I do not know bat language).

Another problem is that when trying to define a custom icon for the program, the parameters are set, and the final packaged program is not brought, I do not know whether there is a problem with my settings or the problem of qpt itself, but anyway, the same reason is for our own use, it does not matter if the icon is not an icon.

The final packaged program comes with two folders, which the author also wrote in the introduction. What the program looks like:

Here, in order to easily view the results of the run, I also added a output control to get the print() output content.

Sum up

At this point, the task of agile development is over. It took less than a week, thanks to paddleocr’s powerful recognition model and qpt’s powerful open source packaging. If you need it later in the program, you can leave a message in the comment area or mail me directly. I can pack it to Baidu Cloud and send it to the people who need it. I will organize the code plan and put it in github when I am free later.
