python+paddleocr 进行图像识别、找到文字在屏幕中的位置

目录


前言

最近在做自动化测试,因为是处理过的界面,所以使用pywinauto,LDTP获取控件进行操作的方法不可行,于是选择使用pyautogui进行图像识别与键盘鼠标控制。

但是单独使用pyautogui测试效率很低,并且pyautogui图片识别并没有opencv识别率高,所以需要结合其他图像库使用。

在使用的过程中发现,仅仅使用图像识别有时匹配度比较低,使用opencv进行图像识别定位,是图像像素太小查找成功的几率大大降低,于是想到使用OCR文本识别的方法对其进行查找,结合在一起使用,大大提高了工作效率。   

OCR图像识别我试过Tessract-ocr和paddleocr,发现Tessract-ocr识别正确率太低了,实在不推荐使用。

有关paddleocr的信息可以去github上查看:https://github.com/PaddlePaddle/PaddleOCR

于是想要记录一下,也提供给大家参考学习。

1、安装paddleocr

使用以下命令进行安装:

pip install paddleocr

2、安装PIL

PythonPIL(Python Image Library)是一款用来处理图像的开源库,可实现图像的读取、格式转换、简单编辑、保存等功能。在Python中使用PIL库可以很方便地对图像进行操作。

与 Pillow 相比,OpenCV 和 Scikit-image 的功能更为丰富,所以使用起来也更为复杂,主要应用于机器视觉、图像分析等领域,比如众所周知的“人脸识别”应用 。

在这里我们使用PIL对图像进行处理。

使用以下命令进行安装:

pip install pillow

3、安装numpy

NumPy(Numerical Python)是Python的一种开源的数值计算扩展。这种工具可用来存储和处理大型矩阵,比Python自身的嵌套列表(nested list structure)结构要高效的多(该结构也可以用来表示矩阵(matrix)),支持大量的维度数组与矩阵运算,此外也针对数组运算提供大量的数学函数库。

我们使用numpy用来处理屏幕截图,把其转换为矩阵,再进行下一步处理。

使用以下命令进行安装:

pip install numpy

4、 安装pyautogui

pyautogui是一个Python模块,可以模拟用户在屏幕上的鼠标和键盘操作。它可以自动化鼠标和键盘输入,可以用于各种自动化任务,例如GUI测试、自动化数据输入、自动化游戏玩法等。pyautogui提供了一组函数来控制鼠标和键盘,例如移动鼠标、单击、双击、右键单击、按下和释放键等。它还提供了一些额外的功能,例如捕捉屏幕截图、识别颜色和图像等,以及其他一些实用工具,例如获取屏幕尺寸和鼠标位置。

使用以下命令进行安装:

pip install pyautogui

5、进行文本识别

安装好库之后,在脚本文件开头导入

import numpy
from pyautogui import *
from PIL import Image
import numpy as np
from paddleocr import PaddleOCR, draw_ocr

def get_curtime(time_format="%Y-%m-%d %H:%M:%S"):
    curTime = time.localtime()
    curTime = time.strftime(time_format, curTime)
    return curTime

def ocr_img_text(path="", saveimg=False, printResult=False):
    '''
    图像文字识别

    :param path:图片路径
    :param saveimg:是否把结果保存成图片
    :param printResult:是否打印出识别结果
    :return:result,img_name
    '''
    image = path

    # 图片路径为空就默认获取屏幕截图 
    if image == "":
        image = screenshot() #使用pyautogui进行截图操作
        image = np.array(image)
    else:
        # 不为空就打开
        image = Image.open(image).convert('RGB')

    ocr = PaddleOCR(use_angle_cls=True, lang="ch")  # need to run only once to download and load model into memory

    result = ocr.ocr(image, cls=True)
    if printResult is True:
        for line in result:
            for word in line:
                print(word)

    # 识别出来的文字保存为图片
    img_name = "ImgTextOCR-img-" + get_curtime("%Y%m%d%H%M%S") + ".jpg"
    if saveimg is True:
        boxes = [detection[0] for line in result for detection in line]  # Nested loop added
        txts = [detection[1][0] for line in result for detection in line]  # Nested loop added
        scores = [detection[1][1] for line in result for detection in line]  # Nested loop added
        im_show = draw_ocr(image, boxes, txts, scores)
        im_show = Image.fromarray(im_show)
        im_show.save(img_name)

    return result, img_name

在main中调用,不指定path路径,默认使用屏幕截图进行文本识别,设置输出识别结果到控制台,设置保存识别结果为图片,运行:

if __name__ == '__main__':
    ocr_img_text(saveimg=True, printResult=True)

6、识别结果

识别的屏幕截图为一篇博客:

等待3-10s输出结果,识别文本越多,速度越慢,运行结果如下:

7、获取文字在图片/屏幕中的位置

 我们可以看到识别完成的图像已经把文字区域框出来了,并且让我们仔细看输出的结果:

[[1350.0, 151.0], [1386.0, 151.0], [1386.0, 175.0], [1350.0, 175.0]], ('目录', 0.9999495148658752)]

我截取出“目录”的输出信息,发现输出的一个结果其实是由两个列表组成的,在这里为了方便我把这一个结果列表称为result,那么result[0]就是文字的四个角的位置,result[1]就是识别出的文字与confidence可信度。

那么要怎么样获取到某一个文字的位置呢?

可以看以下代码:

def ocr_get_txt_pos(path="", text=""):
    '''
    获取文字与位置对应map
    :param path:图片路径,图片路径为空则默认获取当前屏幕截图
    :param text: 筛选需要查找的内容,匹配所有位置
    :return:list
    '''

    result, img_path = ocr_img_text(path, saveimg=True)

    print("图片识别结果保存:", img_path)

    #把结果列表的两个值分别再存为两个list
    poslist = [detection[0][0] for line in result for detection in line] #取top一个点的位置
    txtlist = [detection[1][0] for line in result for detection in line] 

    # 用list存文字与位置信息
    find_txt_pos = []

    items = 0

    if text == "":
        find_txt_pos = result
    else:
        for i in range(len(poslist)):
            if txtlist[i] == text:
                find_txt_pos.append(poslist[i])
                items += 1

    print(find_txt_pos)
    return find_txt_pos

我们可以去通过输入想要寻找的文字,函数会返回文字的位置,关于图片的位置,我只取了一个点top去使用,如果有其他的需求可以取多个点自行修改。

跑一下:

if __name__ == '__main__':
    ocr_get_txt_pos(text="目录")

 找到的位置已经输出了:

 对于有多个同样的文字,则会返回一个列表,存所有对应文字的信息:

if __name__ == '__main__':
    ocr_get_txt_pos(text="二、使用步骤")
[2023/12/06 10:36:05] ppocr DEBUG: dt_boxes num : 102, elapsed : 0.44469285011291504
[2023/12/06 10:36:06] ppocr DEBUG: cls num  : 102, elapsed : 0.7088828086853027
[2023/12/06 10:36:18] ppocr DEBUG: rec_res num  : 102, elapsed : 11.481557846069336
图片识别结果保存: ImgTextOCR-img-20231206103618.jpg
[[1350.0, 286.0], [342.0, 798.0]]

获取到位置后就可以进行点击操作了!

8、pyautogui+paddleocr鼠标操作

如果要进行点击,pos的值其实需要一些偏移量:

if __name__ == '__main__':
    pos_list = ocr_get_txt_pos(text="总结")

    # 取一个点进行点击操作
    pos_x, pos_y = pos_list[0]
    moveTo(pos_x + 5, pos_y + 5)
    click()

结果如下:

 这样就操作成功了!
