小弟最近想用VS Code 建置Open CV(C++)環境，但是爬了很多文卻一直架不起來，希望能有大大能幫助我。希望能回答的愈詳細越好，包括:

MINGW、Open CV的版本(X64,X32好像有差)
VSCODE 的extentions 選擇
c_cpp_proporties.json, task.json, launch.json的配置
如果用cmake的大大也請告訴我要如何用cmd，而非vscode的terminal輸出

感激不盡!!!

在fysh711426大大的幫助下，本問題已解決。

能提供更多的資訊嗎?
例如 Open CV 版本
或希望環境具有那些功能

您好，我用open cv版本是3.41、mingw32。
我希望可以編譯/執行基本的opencv 功能(例如輸出圖片，將彩色的照片轉為灰階)，我目前遇到的問題是vscode(應該說mingw)讀不到open cv的library, 甚至讀不到header file，即使我已經將他們加入path裡面了。

以上網址是我參考的配置方法，因為某些資料夾的路徑不同做了點更動，其他都一樣
然後就:
fatal error: opencv2/opencv.hpp: No such file or directory
#include<opencv2/opencv.hpp>

目前測試結果(失敗)

安裝 OpenCV-MinGW-Build (3.4.1)
新增環境變數 C:\MinGW\bin 和 C:\opencv\bin
設定 VSCode

launch.json

            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

不過還是失敗了，雖然有編譯成功，但執行會出錯。

我試了你的方法了，好像抓的到<opencv2/opencv.hpp>，
因為intellisense 有提示出來，開心~
但是沒有編譯成功QQ
dll file not recognized file format not recognized

上網查了一下，如果把tasks.json 中的這部分:

"args": [
                "-g",
                "${file}",
                "-o",
                "${fileBasenameNoExtension}.exe"
        ]

改成

"args": [
                "-c", //change!!
                "${file}",
                "-o", 
                "${fileBasenameNoExtension}.exe"
        ]

則會變成:

還是不行
