OpenCV C++ VS 環境搭建

OpenCV下載地址

添加系統環境變量

Path：
D:\install\OpenCV\opencv\build
D:\install\OpenCV\opencv\build\x64\vc14\bin

也有說添加如下Path:
D:\install\OpenCV\opencv\build\x64\vc14\bin
D:\install\OpenCV\opencv\build\x64\vc15\bin

新建一個win32控制檯項目工程

test_opencv.cpp

#include <iostream>
#include <opencv.hpp>

using namespace std;
using namespace cv;
int main()
{
	VideoCapture cap(0);
	Mat frame;
	while (true) {
		cap >> frame;
		imshow("frame", frame);
		waitKey(10);
	}
	return 0;
}

配置項目屬性

VC++目錄–包含目錄：
D:\install\OpenCV\opencv\build\include

VC++目錄–庫目錄：
D:\install\OpenCV\opencv\build\x64\vc14\lib

鏈接–輸入–附加依賴項：
D:\install\OpenCV\opencv\build\x64\vc14\lib\opencv_world341.lib;
D:\install\OpenCV\opencv\build\x64\vc14\lib\opencv_world341d.lib;

運行Release X64
