基于MATALB的植物病虫害识别系统设计与实现(已完结)
基于MATALB的植物病虫害识别系统设计与实现
·
（随便看看就好，主要是课设结束了电脑没空间了舍不得删）
本篇博客主要是有下面两个方面的内容：
一、App Designer工具设计交互界面
二、MATLAB深度学习模块中VGG-19模型的使用
目录
（MATLAB R2021a）
一、App Designer工具使用
1.创建新的App（简单的操作我就不多说了）
登录界面
注册用户界面
密码修改界面
主页面
App Designer工具一般情况下只有给加入的组件添加了回调函数才能编辑代码界面，以下直接贴相关控件的代码。
2.设置背景图和初始化相关组件
% Code that executes after component creation
function startupFcn(app)
im =axes('units','normalized','pos',[0 0 1 1]);
i = imread('*.jpg'); %随便寻找一张图片
image(app.UIAxes,i); %在坐标区显示背景
set(im,'handlevisibility','off','visible','off');
app.*.Value=''; %初始化/清空账号框
app.*.Value=''; %初始化/清空密码框
end
% Button down function: UIAxes
function UIAxesButtonDown(app, event) %设坐标区回调来固定背景图片
%啥也不用写
end
3.登录页面组件的相关代码
% Button pushed function: *
function *ButtonPushed(app, event) %“登录”功能
global *; %账户框数据全局变量
global *; %密码框数据全局变量
if isempty(app.*.Value)
errordlg('用户名或密码错误','错误提醒','modal');
app.*.Value='';
app.*.Value='';
elseif isempty(app.*.Value)
errordlg('用户名或密码错误','错误提醒','modal');
app.*.Value='';
app.*.Value='';
elseif(*=="******" && *=="******") %设置登录账号密码
delete(gcf);
*; %跳转至主页面
elseif ~isempty(app.*..Value)
[~,loginname] = xlsread('*.xls','B:B'); %调用账号Excel表
[~,logincode] = xlsread('*.xls','B:B'); %调用密码Excel表
[~,A] = xlsread('*.xls','A:A'); %读表头
if ~iscell(A)
B = maxk(A,1);
else
miu = cell2mat(A);
X = str2num(miu); %#ok<ST2NM>
B = maxk(X,1);
end
for a = 1:B
lname = string(loginname(a));
lcode = string(logincode(a));
if (*==lname && *==lcode)
delete(gcf);
*; %跳转至主页面
break;
end
if a == B
errordlg('用户名或密码错误','错误提醒','modal');
app.*.Value='';
app.*.Value='';
end
end
else
errordlg('用户名或密码错误','错误提醒','modal');
app.*.Value='';
app.*.Value='';
end
end
% Value changed function: * %账号框数据获取
function *ValueChanged(app, event)
global *;
* = app.*.Value;
end
% Value changed function: * %密码框数据获取
function *ValueChanged(app, event)
global *;
* = app.*.Value;
end
% Button pushed function: *
function *ButtonPushed(app, event) %注册功能
if(app.*.Value=="******" && app.*.Value=="******") %设置管理员账号密码
*; %跳转至注册界面
elseif ~isempty(app.*.Value)
errordlg('请输入正确的管理员账户以继续','账户注册指引');
app.*.Value='';
app.*.Value='';
elseif ~isempty(app.*.Value)
errordlg('请输入正确的管理员账户以继续','账户注册指引');
app.*.Value='';
app.*.Value='';
else
helpdlg('请输入管理员账户以继续','账户注册指引');
app.*.Value='';
app.*.Value='';
end
end
% Button pushed function: * %修改密码功能
function *ButtonPushed(app, event)
*; %跳转至密码修改界面
end

end二、深度学习VGG-19模型
1.VGG-19模型的查找与应用
首先按照顺序进行操作
等待最终的训练结果曲线，大概结果如下：
至此，模型训练完毕可以直接使用了。
2.网络模型MATLAB代码段
（不需要刻意准备，一般模型训练结果会直接导出）

%%开始训练

%%模型结果保存

%%精度验证

三、最后一点补充
1.关于标签转换的一些简单代码样例
if label == 'Apple_Normal' %#ok<BDSCA>
l = 1;
elseif label == 'Apple_RD' %#ok<BDSCA>
l = 2;
elseif label == 'Apple_GSD' %#ok<BDSCA>
l = 3;
elseif label == 'Apple_CR' %#ok<BDSCA>
l = 4;
elseif label == 'Apple_ALS' %#ok<BDSCA>
l = 5;
elseif label == 'Cabbage_Normal' %#ok<BDSCA>
l = 6;
elseif label == 'Cabbage_SR' %#ok<BDSCA>
l = 7;
elseif label == 'Cabbage_BBD' %#ok<BDSCA>
l = 8;
elseif label == 'Grape_Normal' %#ok<BDSCA>
l = 9;
elseif label == 'Grape_BBD' %#ok<BDSCA>
l = 10;
elseif label == 'Grape_DM' %#ok<BDSCA>
l = 11;
elseif label == 'Rice_Normal' %#ok<BDSCA>
l = 12;
elseif label == 'Rice_RB' %#ok<BDSCA>
l = 13;
elseif label == 'Rice_BBD' %#ok<BDSCA>
l = 14;
elseif label == 'Rice_BLB' %#ok<BDSCA>
l = 15;
end
标签转化目的是为了对应最终展示结果
2.关于图片预处理的一些简单样例（裁剪图片尺寸大小）
%%filepath为需要修改的图片所在的父目录
imagePath = 'filepath';
%%读取目录文件下的所有图片文件
imageFiles = dir(imagePath);
%%获取图片的数量
numFiles = length(imageFiles);
for i=3:numFiles
j = i-2;
imageFile = strcat(imagePath,imageFiles(i).name);
%%读入图片
A = imread(imageFile);
%%修改图片尺寸
B = imresize(A,[224 224]);
%%保存图片
imwrite(B,imageFile);
end
