windows10系统下安装opencv4.7.0+VSCode+(C++)环境搭建

写在前面(安装包可去官网下载)

1.VScode最新版
2.Opencv:opencv-4.7.0、opencv_contrib-4.7.0(扩展库,可自选是否安装)
3.MinGW-w64:选择GCCWindows版本
4.c-make工具:最新版,应选择二进制版本
注意

  • (1)以上安装包目录文件中不应包含空格空格和其他非法字符,否则后面会出问题;
  • (2)系统已安装或配置Python和Java对应版本,切记安装路径不能包含空格和其他非法字符;
  • (3)c-make解压至系统盘,放其他盘,后面cmake build可能会报错。

环境搭建过程

1 vscode安装:

打开解压好的vscode,运行code.exe进行安装配置,完成后,打开vscode配置c/c++扩展库(想中文显示面板,可在此查找中文插件,安装)。详细步骤如下:

MinGW-w64安装

将其安装包解压后再系统环境变量中添加并保存其bin的Path:如E:\MinGW\bin(避免非法字符)。然后再cmd中输入gcc -version,若如下显示则表示配置成功。

Opencv编译

1.解压c-make包,运行cmake包中bin目录的cmake-gui.exe(如C:\cmake-3.26.0-rc3-windows-x86_64\bin

  • (1)在"Specify the generator for this project"选择时,应选"MinGW Makefiles",编辑器可根据自己实际情况选择,若无要求,则使用默认编译器;
  • (2)opencv扩展安装:在上述step3执行无误后,在Search中输入extra,并选择扩展路径E:\Microsoft-VS-Code\opencv_contrib-4.7.0。点击configure,配置完成后即可点击generate。
  1. 完成配置后,在自己创建的build文件夹==(用于存放opencv编译结果)==中,按住shift+鼠标右键,进入powershell窗口:
  • (1) 输入 MinGW32-make 开始编译,若缺宝库则会很慢(性能较好的笔记本可用 MinGW32-make -j4 ,多CPU同时编译)。
  • (2)编译完成,输入:MinGW32-make install 进行安装。
  • (3)添加编译后的文件环境变量:E:\Microsoft-VS-Code\opencv-4.7.0_build

vscode配置opencv,并test运行

如图,进行创建vscode代码的存储文件夹、配置json文件夹:

对应json文件配置内容如下所示:

  • c_cpp_properties.json
    需配置“includePath” (make生成的文件夹对应位置) 和"compilerPath" (gcc编译器所在位置)

  • Task.json

注意:"command"中g++的配置,如:“E:/MinGW/bin/g++.exe”,以及其他路径的配置。libopencv_core470中的 “470” 表示对应的opencv版本。

代码运行测试

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

int main()
{
    Mat img=imread("C:/Users/Administrator/Desktop/test.jpg");
    //Mat resize_img(img);
    Size dsize = Size(round(0.3 * img.cols), round(0.3 * img.rows));//Size型 改变尺寸
    resize(img, img, dsize, 0, 0, INTER_LINEAR); //使用双线性插值缩放一下尺寸
    //resize(img, resize_img, Size(img.cols/7, img.rows/7));
    cv::imshow("test",img);
    cv::waitKey();
    system("pause");
    return 0;
}
  • 在vscode中按F5运行,结果如下:

    如上图所示,则表示已完成了相关的安装配置,可进行下一步开发测试。
