windows10系統(tǒng)下安裝opencv4.7.0+VSCode+(C++)環(huán)境搭建
寫在前面（安裝包可去官網(wǎng)下載）
1.VScode最新版
2.Opencv：opencv-4.7.0、opencv_contrib-4.7.0（擴展庫，可自選是否安裝）
3.MinGW-w64：選擇GCCWindows版本
4.c-make工具：最新版，應(yīng)選擇二進(jìn)制版本
注意：
- (1)以上安裝包目錄文件中不應(yīng)包含空格空格和其他非法字符，否則后面會出問題；
- (2)系統(tǒng)已安裝或配置Python和Java對應(yīng)版本，切記安裝路徑不能包含空格和其他非法字符；
- (3)c-make解壓至系統(tǒng)盤，放其他盤，后面cmake build可能會報錯。
環(huán)境搭建過程
1 vscode安裝：
打開解壓好的vscode,運行code.exe進(jìn)行安裝配置，完成后，打開vscode配置c/c++擴展庫(想中文顯示面板，可在此查找中文插件，安裝)。詳細(xì)步驟如下：
MinGW-w64安裝
將其安裝包解壓后再系統(tǒng)環(huán)境變量中添加并保存其bin的Path：如E:\MinGW\bin（避免非法字符）。然后再cmd中輸入gcc -version，若如下顯示則表示配置成功。
Opencv編譯
1.解壓c-make包，運行cmake包中bin目錄的cmake-gui.exe（如C:\cmake-3.26.0-rc3-windows-x86_64\bin）
注
- (1)在"Specify the generator for this project"選擇時，應(yīng)選"MinGW Makefiles",編輯器可根據(jù)自己實際情況選擇，若無要求，則使用默認(rèn)編譯器;
- (2)opencv擴展安裝：在上述step3執(zhí)行無誤后，在Search中輸入extra，并選擇擴展路徑E:\Microsoft-VS-Code\opencv_contrib-4.7.0。點擊configure，配置完成后即可點擊generate。
- 完成配置后，在自己創(chuàng)建的build文件夾==(用于存放opencv編譯結(jié)果)==中，按住shift+鼠標(biāo)右鍵，進(jìn)入powershell窗口：
- (1) 輸入 MinGW32-make 開始編譯，若缺寶庫則會很慢（性能較好的筆記本可用 MinGW32-make -j4 ，多CPU同時編譯）。
- (2)編譯完成，輸入：MinGW32-make install 進(jìn)行安裝。
- (3)添加編譯后的文件環(huán)境變量：E:\Microsoft-VS-Code\opencv-4.7.0_build
vscode配置opencv，并test運行
如圖，進(jìn)行創(chuàng)建vscode代碼的存儲文件夾、配置json文件夾：
對應(yīng)json文件配置內(nèi)容如下所示：
-
c_cpp_properties.json
需配置“includePath” (make生成的文件夾對應(yīng)位置) 和"compilerPath" (gcc編譯器所在位置)
{

"includePath": [

- launch.json

}
- Task.json
注意："command"中g(shù)++的配置，如：“E:/MinGW/bin/g++.exe”，以及其他路徑的配置。libopencv_core470中的 “470” 表示對應(yīng)的opencv版本。

代碼運行測試

#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 改變尺寸
resize(img, img, dsize, 0, 0, INTER_LINEAR); //使用雙線性插值縮放一下尺寸
//resize(img, resize_img, Size(img.cols/7, img.rows/7));
cv::imshow("test",img);
cv::waitKey();
system("pause");
return 0;
