# 务必阅读本VSCode配置Opencv的步骤 ## CSDN的答案不靠谱 ## 如果VS Studio配置Opencv 可以在这个笔记doc中的第4章，第4.5节找到答案。 [https://github.com/chenbei97/myLeetCode/imageProcessingV3.docx](https://github.com/chenbei97/myLeetCode/blob/main/imageProcessingV3.docx) ## 配置Git、Mingw 可在这个md文档找到答案，并给出了VsCode配置C++和Python的方法。 [https://github.com/chenbei97/ComputerVision/markdown/配置环境相关/Git和Vscode配置.md](https://github.com/chenbei97/ComputerVision/blob/main/markdown/配置环境相关/Git和Vscode配置.md) 本人的Mingw的路径就在C盘。 ``` C:\msys64 ``` 记得要把bin、include文件夹都加入环境变量。 ``` C:\msys64\mingw64\bin C:\msys64\mingw64\include ``` ## 现在VsCode开始配置Opencv 这个过程参考知乎的答案。 [如何优雅地在你的Vscode上使用opencv（C++接口，Windows篇，实则踩坑经历） - 知乎 (zhihu.com)](https://zhuanlan.zhihu.com/p/402378383?utm_source=wechat_session&utm_medium=social&utm_oi=1173235761410818048&utm_campaign=shareopn) 答案提供好了Opencv编译好的版本，下载地址在下方。 [opencv编译好的版本](https://gitee.com/kirigaya/opencv_built_by_gcc_on_-windows) 现在要做的事，下载的文件有lib、include、bin。把里边的内容直接复制到上边Mingw的对应文件夹中。 在c_cpp_properties.json文件中"includePath"字段加上2个地址 ```json { "configurations": [ { "name": "Win32", "includePath": [ "${workspaceFolder}/**", "C:/msys64/mingw64/include", "C:/msys64/mingw64/include/opencv2" ], "defines": [ "_DEBUG", "UNICODE", "_UNICODE" ], "windowsSdkVersion": "10.0.18362.0", "compilerPath": "C:/msys64/mingw64/bin/g++.exe", "intelliSenseMode": "windows-gcc-x64", "cppStandard": "c++20", "cStandard": "c17" } ], "version": 4 } ``` tasks.json的内容。 注意G++的命令，先-g，然后某个地址的cpp，-std=c++20，然后列出目录-I，然后列出动态库，这些动态库就是lib文件＋下的。myLeetCode\myPleasure\\myOpencv是我的工作目录。 ```c++ { "version": "2.0.0", "tasks": [ { "type": "cppbuild", "label": "C/C++: g++.exe 生成活动文件", "command": "C:\\msys64\\mingw64\\bin\\g++.exe", "args": [ "-fdiagnostics-color=always", "-g", //"${workspaceFolder}\\binaryTree\\*.cpp", // ${file},可以构建多个cpp文件而不是单个 //"${workspaceFolder}\\linearArray\\*.cpp", //"${workspaceFolder}\\linkedList\\*.cpp", //"${workspaceFolder}\\characterString\\*.cpp", //"${workspaceFolder}\\coreAlgorithms\\*.cpp", //"${workspaceFolder}\\STLTestCode\\*.cpp", "${workspaceFolder}\\myPleasure\\myOpencv\\*.cpp", "-std=c++20", "-I","C:/msys64/mingw64/include", "-I","C:/msys64/mingw64/lib", "-l","libopencv_calib3d452", "-l","libopencv_core452", "-l","libopencv_dnn452", "-l","libopencv_features2d452", "-l","libopencv_flann452", "-l","libopencv_gapi452", "-l","libopencv_highgui452", "-l","libopencv_imgcodecs452", "-l","libopencv_imgproc452", "-l","libopencv_ml452", "-l","libopencv_objdetect452", "-l","libopencv_photo452", "-l","libopencv_stitching452", "-l","libopencv_video452", "-l","libopencv_videoio452", "-o", //"${workspaceFolder}\\binaryTree\\main.exe", // ${workspaceFolder}\\myProgram.exe 可以替换为硬编码名 //${fileDirname}\\${fileBasenameNoExtension}.exe //"${workspaceFolder}\\linearArray\\main.exe", //"${workspaceFolder}\\linkedList\\main.exe", //"${workspaceFolder}\\characterString\\main.exe", //"${workspaceFolder}\\coreAlgorithms\\main.exe", //"${workspaceFolder}\\STLTestCode\\main.exe", "${workspaceFolder}\\myPleasure\\myOpencv\\main.exe", ], "options": { "cwd": "${fileDirname}" }, "problemMatcher": [ "$gcc" ], "group": { "kind": "build", "isDefault": true }, "detail": "编译器: C:\\msys64\\mingw64\\bin\\g++.exe" } ] } ``` 命令行就是这样的命令了，这里是有个测试代码文件.\myLeetCode\myPleasure\myOpencv\testFiles\test_opencv_for_vscode.cpp ```c++ g++.exe -fdiagnostics-color=always -g C:\Users\chenbei\VscodeItems\myLeetCode\myPleasure\myOpencv\testFiles\*.cpp -std=c++20 -I C:/msys64/mingw64/include -I C:/msys64/mingw64/lib -l libopencv_calib3d452 -l libopencv_core452 -l libopencv_dnn452 -l libopencv_features2d452 -l libopencv_flann452 -l libopencv_gapi452 -l libopencv_highgui452 -l libopencv_imgcodecs452 -l libopencv_imgproc452 -l libopencv_ml452 -l libopencv_objdetect452 -l libopencv_photo452 -l libopencv_stitching452 -l libopencv_video452 -l libopencv_videoio452 -o C:\Users\chenbei\VscodeItems\myLeetCode\myPleasure\myOpencv\testFiles\test_opencv_for_vscode.exe // 编译命令 cd myPleasure\myOpencv\testFiles // 先到输出文件夹 .\test_opencv_for_vscode.exe // 执行 ``` luanch.json。 ```json { // 使用 IntelliSense 了解相关属性。 // 悬停以查看现有属性的描述。 // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "C/C++: g++.exe Build and debug active file", "type": "cppdbg", "request": "launch", //"program": "${workspaceFolder}\\binaryTree\\main.exe", // ${fileDirname}\\${fileBasenameNoExtension}.exe //"program": "${workspaceFolder}\\linearArray\\main.exe", //"program": "${workspaceFolder}\\linkedList\\main.exe", //"program": "${workspaceFolder}\\characterString\\main.exe", //"program": "${workspaceFolder}\\coreAlgorithms\\main.exe", //"program": "${workspaceFolder}\\STLTestCode\\main.exe", "program": "${workspaceFolder}\\myPleasure\\myOpencv\\main.exe", "args": [], "stopAtEntry": false, "cwd": "${fileDirname}", "environment": [], "externalConsole": true, "MIMode": "gdb", "miDebuggerPath": "C:\\msys64\\mingw64\\bin\\gdb.exe", "logging":{"engineLogging":true}, "setupCommands": [ { "description": "为 gdb 启用整齐打印", "text": "-enable-pretty-printing", "ignoreFailures": true }, { "description": "将反汇编风格设置为 Intel", "text": "-gdb-set disassembly-flavor intel", "ignoreFailures": true } ], "preLaunchTask": "C/C++: g++.exe 生成活动文件" } ] } ``` 现在ctrl_shift+b就可以编译你的项目文件在myOpencv文件夹了，执行上述命令执行的是testFiles的。 #include <opencv2/xfeatures2d.hpp> 文件夹包含不了是因为知乎提供的opencv2版本没有 本人因为事先在VS中编译过，所以可以使用，而这个opencv2文件就在 .\myLeetCode\myPleasure\myOpencv\build\include\opencv2 可以用这个版本覆盖�
