【机器视觉学习笔记】OpenCV C++的安装、配置及多版本共存 （VS2015）

平台：Windows 10 20H2
Visual Studio 2015
OpenCV 2.4.13.6

---

本文参考自最新opencv-c++安装及配置教程(VS2019 C++ & opencv4.4.0) —— /我爱西红柿炒鸡蛋/
及vs2013 配置 OpenCV2.4.9和 OpenCV3.3 多版本共存 —— Galaxy.Dong

之前已安装过OpenCV 4.5.3，由于需要用到OpenCV 2.4.13.6，故作此记录

下载

官方下载：Releases - OpenCV
选择需要的版本，本文中选择OpenCV – 2.4.13.6

下载完成后打开
输入要存放的位置并开始解压

（可选 —— 二选一）添加环境变量

此电脑-属性-高级系统设置


高级-环境变量

编辑Path

添加bin文件夹的路径

新建项目和配置

新建项目后配置项目的属性

配置包含目录

（根据所需选择平台）

添加解压后opencv文件夹内的include文件夹及其子文件夹的路径，如

D:\Work\OpenCV\opencv2\opencv\build\include
D:\Work\OpenCV\opencv2\opencv\build\include\opencv
D:\Work\OpenCV\opencv2\opencv\build\include\opencv2

配置库目录

（根据所需选择平台）

添加所需架构的路径

如

D:\Work\OpenCV\opencv2\opencv\build\x64\vc14\lib

添加库

（根据所需选择平台）

加入lib文件夹下的以".lib"结尾的库文件名
其中以"d.dll"结尾的为Debug时需要的库
不带’d’的则为Release时需要的库

这些文件名可用如下python脚本提取

import os
filePath = r'D:\Work\OpenCV\opencv2\opencv\build\x64\vc14\lib'

DebugLibList = []
ReleaseLibList = []

for _ in os.listdir(filePath):
    if _.endswith('d.lib'):
        DebugLibList.append(_)
    elif _.endswith('.lib'):
        ReleaseLibList.append(_)

print("DebugLibList:\n")
for _ in DebugLibList:
    print(_)

print("\nReleaseLibList:\n")
for _ in ReleaseLibList:
    print(_)

（可选 —— 二选一）添加dll文件的路径

（根据所需选择平台）

添加
PATH=D:\Work\OpenCV\opencv2\opencv\build\x64\vc14\bin;%PATH%

路径为dll文件所在的路径

测试

#include <iostream> 
using namespace std;

#include <opencv2/opencv.hpp>
using namespace cv;

int main(int argc, char * argv[])
{
    
    
	Mat TestImg = Mat(500, 500, CV_8UC3, Scalar(0, 255, 0));

	namedWindow("TestImg");
	imshow("TestImg", TestImg);

	waitKey(0);
	return 0;
}
