前言：大家好，我是一名高中物理教师，比较喜欢学习编程，由于平时批改作业比较忙，所以突然冒出个想法，做个摄像头答题卡识别就会减轻我平时批改作业的很多负担，特别是选择题，重复性的劳动，意义不大，如果用机器代替工作那该多好呀，网上一搜，有很多教程，但是都不太满意，所以我趁着躲避新冠在家隔离的这段时间，边学边做，终于做成了，还没开学，等开学了就去试试，通过博客园，把我的心得分享给大家！

首先,我学习了三本书，python3.7  Pyqt5  opencv ，对我的帮助很大，感谢这几本书的作者。

第二，软件环境： anaconda(python3.7)+pycharm +pqty5 + opencv4.2.0+Excel2016 + 一堆库

第三，硬件环境： 高拍仪(1000W像素，分辨率1920*1080)

、

第四，实现的功能：   ①识别选择题

　　　　　　　　　　②识别名字(用汉字区位码)

　　　　　　　　　　③识别考号

　　　　　　　　　　④计算得分

　　　　　　　　　　⑤统计全班的每题得分率

　　　　　　　　　　⑥选择题柱状图

 

第五，答题卡设置要求：横平竖直，格子的宽高相同（我设置的是64行，23列），便于分割！

第六，识别部分：① 打开摄像头，捕获一帧。

　　　　　　　　② 对图像四角变换

　　　　　　　　④ 把图像分割，计算每个格子中涂卡面积占比

　　　　　　　　⑤ 输出选项到列表

 

具体代码：　　　　　　　　

  1. #① 打开摄像头，捕获一帧。这里用了定时器，否则会卡
  2. self.timer = QTimer()  # 初始化定时器
  3. self.timer.timeout.connect(self.time)#定时器信号
  4. self.cap = cv2.VideoCapture(0) #打开视频
  5. self.cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1366)#图像宽
  6. self.cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 768) #图像高
  7. self.timer.start(1)
    self.ret,self.frame = self.cap.read() #读取内存中的帧
  1. # ②对图像四角变换
  2.         if (self.cap.isOpened()):
  3.             M = cv2.getRotationMatrix2D((self.frame.shape[1] / 2, self.frame.shape[0] / 2), -90, 0.8)  # 获得旋转矩阵
  4.             self.frame = cv2.warpAffine(self.frame, M, (self.frame.shape[1], self.frame.shape[0]))  # 旋转90度
  5.             gray = cv2.cvtColor(self.frame, cv2.COLOR_BGR2GRAY)  # 转换为灰度图像
  6.             blurred = cv2.GaussianBlur(gray, (3, 3), 0)  # 高斯滤波1
  7.             edged = cv2.Canny(blurred, 10, 100)  # 边缘检测
  8.             #cv2.imshow(\'edged\', edged)
  9.             cnts = cv2.findContours(edged, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)  # 查找轮廓
  10.             cnts = cnts[1] if imutils.is_cv2() else cnts[0]  # # 用以区分OpenCV2.4和OpenCV3
  11.             docCnt = None
  12.             if len(cnts) > 0:  # 确保至少有一个轮廓被找到
  13.                 cnts = sorted(cnts, key=cv2.contourArea, reverse=True)  # 将轮廓按大小降序排序
  14.                 for c in cnts:  # 对排序后的轮廓循环处理
  15.                     peri = cv2.arcLength(c, True)  # 周长# 获取近似的轮廓
  16.                     approx = cv2.approxPolyDP(c, 0.02 * peri, True)  # 如果近似轮廓有四个顶点，那么就认为找到了答题卡
  17.                     if len(approx) == 4:
  18.                         docCnt = approx
  19.                         break
  20.             self.framexianshi = self.frame.copy()  # 复制原图
  21.             self.paper = four_point_transform(self.frame, docCnt.reshape(4, 2))  # 对原始图像进行四点透视变换
  22.             self.framexianshi = cv2.drawContours(self.framexianshi, cnts, 0, (0, 255, 0), 2)  #画绿边轮廓
  1. #③ 形态学变换(灰度 反向二值化 开运算 膨胀) 
  2. paper = cv2.resize(self.paper, (1196, 1946))  # 重新缩放指定尺寸统一尺寸 便于分割
  3.             #cv2.imshow(\'suofanghou\', paper)
  4.             hanggao = paper.shape[0]
  5.             hanggao_1 = hanggao // 64
  6.             liekuan = paper.shape[1]
  7.             liekuan_1 = liekuan // 23
  8.             huidu = cv2.cvtColor(paper, cv2.COLOR_BGR2GRAY)  # 灰度图
  9.             t, erzhihua = cv2.threshold(huidu, 95, 255, cv2.THRESH_BINARY_INV)  # 反向二值化
  10.             # cv2.imshow(\'erzhihua\', erzhihua)
  11.             k = np.ones((8, 8), np.uint8)  # 开运算
  12.             kaiyunsuan = cv2.morphologyEx(erzhihua, cv2.MORPH_OPEN, k)  # 开运算
  13.             # cv2.imshow(\'kaiyunsuan\', kaiyunsuan)
  14.             peng = np.ones((3, 3), np.uint8)
  15.             kaiyunsuan = cv2.dilate(kaiyunsuan, peng)  # 膨胀

 

  1. #分割后的图像
  2.             for heng in range(0, hanggao + hanggao_1, hanggao_1):  # 显示分割的横线竖线
  3.                 paper = cv2.line(paper, (0, heng), (liekuan, heng), (0, 0, 255), 1)  # 显示分割的横线竖线
  4.             for j in range(0, liekuan, liekuan_1):  # 显示分割的横线竖线

　　　　　　　　② 把学生选项输出到列表2

　　　　　　　　③ 对比两个列表的元素 判断正误

  1. #① 判断正确与否是请教QQ群里面的大神，我觉得每次请教可以用红包的方式来请教，虽然都差钱，但是每次你花10元-20元的红包来请教，一来你耽误了别人的宝贵时间，二来别人看你的问题给你解答要动脑筋的，我觉得付费是理所当然的

第八，程序打包：

安装：pip uninstall pyinstaller

打开：CMD

切换路径：自己工程的路径并输入 pyinstaller -F -w Run.py

如果出现错误：

1.在执行命令 pyinstaller -F D:\py\programe\banksystem.py打包生成.exe文件时报错：python maximum recursion depth exceeded

2.处理办法分三步走：
①.命令行输入：pyi-makespec -F D:\py\programe\清单核对\bomcheck.py，会生成一个bomcheck.spec文件
②.找到bomcheck.spec这个文件给它的第二行插入下面两行代码
import sys
sys.setrecursionlimit(50000)
③.重新编译生成命令行输入：pyinstaller -F Run.spec即可

总结：说得好像论七八糟，大神请略过，第一次发博客手生，请见谅！
