### VS2019中安装Opencv ###

#### 一、下载Opencv ####

在opencv官网中下载，地址：[https://sourceforge.net/projects/opencvlibrary/][https_sourceforge.net_projects_opencvlibrary]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70]  
点击DownLoad，等待5秒钟后会开始自动下载，如果想下载其他版本的还可以在这里找：[https://opencv.org/releases/][https_opencv.org_releases]

#### 二、安装Opencv ####

1.双击下载好的.exe文件，选择好安装位置，点击Extract。  
![在这里插入图片描述][2021061017000358.png]  
解压完成后在opencv文件夹中有如下内容：

2.添加环境变量  
右键此电脑，选择属性，打开高级系统设置，选择环境变量，在系统变量中找到path变量，双击打开它，点击新建，将“H:\\opencv\\build\\x64\\vc15\\bin”路径添加进环境变量中。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 3]  
3.在“H:\\opencv\\build\\x64\\vc15\\bin”目录下找到以下三个文件：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 4]  
4.将“opencv\_world452.dll”、“opencv\_world452d.dll”和“opencv\_videoio\_ffmpeg452\_64.dll”这三个文件复制到“C:\\Windows\\System32”这个目录下。  
![在这里插入图片描述][2021061017315888.png]

#### 三、在VS2019中配置Opencv ####

1.打开VS2019，新建空项目，选择好存储路径后点击创建。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 5]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 6]  
2.右键创建好的项目，选择属性，打开属性页后选择“Debug|X64”模式。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 7]

3.在VC++目录中选择“包含目录”，点击编辑，添加以下两个路径：

H:\opencv\build\include
    H:\opencv\build\include\opencv2

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 9]

4.在VC++目录中选择“库目录”，点击编辑，添加以下路径：

H:\opencv\build\x64\vc15\lib

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 11]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 12]  
5.在链接器中选择“输入”，选择“附加依赖项”，点击编辑，添加以下变量：

opencv_world452d.lib

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 13]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 14]  
属性配置完成，下面进行简单测试。

#### 四、测试 ####

在源文件中新建项，添加.cpp源文件。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1d4eTk3MTEyMg_size_16_color_FFFFFF_t_70 15]  
测试代码如下：

#include<opencv2/imgcodecs.hpp>
    #include<opencv2/highgui.hpp>
    #include<opencv2/imgproc.hpp>
    #include<iostream>
    using namespace cv;
    using namespace std;
    
    int main()
    {
        
    	string path = "H:\\test.jpg"; //这里的路径是你测试图片的存放路径，用"\\"来分隔每个文件
    	Mat img = imread(path);
    	imshow("Image", img);
    	waitKey(0);
    	return 0;
    }

结果如下：

至此，在VS2019中安装Opencv就成功完成啦~
