答题卡扫描识别系统是一款高效准确地读取和分析考试或测验中使用的答题卡信息的软件工具。通过高精度光学字符识别技术，快速统计分数并检测潜在错误，大大减轻了人工阅卷的工作量。
毕业设计和课程设计全套资料包括主程序代码如下：
```matlab
clc;
clear all;
close all;
warning off all;
I = imread(images\\1.jpg);
I1 = Image_Normalize(I, 0); % 图像归一化
hsize = [3 3];
sigma = 0.5;
I2 = Image_Smooth(I1, hsize, sigma, 0);
I3 = Gray_Convert(I2, 0);
bw2 = Image_Binary(I3, 0); % 二值化处理
[~, ~, xy_long] = Hough_Process(bw2, I1, 0); % 霍夫变换
angle = Compute_Angle(xy_long); % 计算角度
[I4, bw3] = Image_Rotate(I1, bw2, angle * 1.8, 0); % 图像旋转
[bw4, Loc1] = Morph_Process(bw3, 0); % 形态处理
[Len, XYn, xy_long] = Hough_Process(bw4, I4, 0);
[bw5, bw6] = Region_Segmation(XYn, bw4, I4, 0);
[stats1, stats2, Line] = Location_Label(bw5, bw6, I4, XYn, Loc1, 1);
[Dom, Aom, Answer, Bn] = Analysis(stats1, stats2, Line, I4);
