一.文件下载：
1.MinGW下载
2.Cmake下载
3.Opencv下载
二.配置环境变量：
三.vscode 配置
1、launch.json
2、c_ cpp_ properties json
3、tasks json
四.测试
一.文件下载
1.MinGW下载（MinGW-w64 - for 32 and 64 bit Windows - Browse Files at SourceForge.net）
单独在一个盘里面新建一个文件夹 名字随意 我的（MinGw）下载完成会在这个文件夹里面 第一个文件是解压之后的文件
2.Cmake下载（https://cmake.org/files/v3.20/）
选择这个版本进行下载 然后像上面一样新建一个文件夹来存放cmake 我的（cmake）第一个是解压后的文件.
3.Opencv下载（https://github.com/huihut/OpenCV-MinGW-Build）
由于opencv的源代码用mingw编译坑挺多的 这里直接下载已经编译好的 省去那些麻烦 下载并且解压后得到这两个文件夹
二.配置环境变量
1.配置环境变量
打开控制面板
1.添加MinGW的环境变量：（点中后确定）
会有下面这个路径 添加完后还要点击空白处！！！
2.添加cmake的环境变量：（选中文件点击确定）
出现这个路径说明成功
3.添加OpenCV环境变量 之前要点击空白处
出现这个路径表示成功 最后确定 环境变量配置完成
5.检查安装配置是否完成 ctrl+R ,输入cmd，调出 cmd命令窗口。
输入: gcc -v
说明MinGw安装配置完成。
输入：cmake -version
说明cmake只能装配置完成
三.vscode 配置
打开vscode 需要安装上相应的扩展
可以新建一个文件夹 专门放OpenCV工程
在vscode里面新建一个main.cpp 文件 要先创建一 个.vscode文件夹, 前面有一个点，这个文件夹存放3个json配置文件，3个json文件要放进.vscode里面！！！
在main.cpp里面加入这段代码
/*********************** 显示指定地址的图片*****************************/
#include<iostream>
#include<opencv2/core/core.hpp>
#include<opencv2/highgui/highgui.hpp>
using namespace std;
using namespace cv;
int main(int argc, char** argv)
{
Mat image;image = imread("D:\\OpenCV\\z23.jpg");if (image.data == nullptr) //nullptr是c++11新出现的空指针常量{cout << "图片文件不存在" << endl;}else{//显示图片imshow("meinv", image);waitKey(0);}// 输出图片的基本信息cout << "图像宽为：" << image.cols << "\t高度为：" << image.rows << "\t通道数为：" << image.channels() << endl;// 遍历每个像素//之所以用y这个名字表示行 是因为图片的坐标系中行号就是yfor (size_t y = 0; y < image.rows; y++){unsigned char* row_ptr = image.ptr<unsigned char>(y);for (size_t x = 0; x < image.cols; ++x) {//这是获得像素数据数组的头指针，注意像素数据可能会有多个通道所以才需要用数组存储unsigned char* data_ptr = &row_ptr[x * image.channels()];//对当前像素逐个通道输出颜色值for (int i = 0; i < image.channels(); ++i) {cout << int(data_ptr[i])<<endl;}}}system("pause");return 0;}
按F5运行会生成一个文件夹.vscode 然后配置里面三个文件 1. launch.json 2、c_ cpp_ properties json 3、tasks json
- launch.json

2、c_ cpp_ properties json
{

3、tasks json
