OpenCV 第一課(安裝與配置)
下載安裝軟件
官網OpenCV下載地址下載最新版本，我下載的是opencv.2.4.13,然后解壓安裝，我寫的路徑是D:\Program Files。注意本文中綠色標注的要換成你自己的安裝路徑。
這里得說一點，可能是因為網速太差的原因，昨天晚上下載了幾次安裝時都提示說“cannott open file'opencv-2.4.13.exe' as archive”。我當時一直不明白是怎么回事，網上中文說這個原因的幾乎沒有，可能大家覺得這種問題不是問題吧。
Sign up
OpenCV Windows install: can not open file “OpenCV-2.4.5.exe” as archive
后來發現是因為網速的原因下載的包總是不全，雖然無論下載多少圖標顯示都是一樣的，但一定要注意下載后的大小是不是和網上安裝包大小一樣，以確定你下的包完整。
配置環境變量
win10 專業版，系統 -> 高級系統設置 -> 環境變量.
在用戶變量中新建變量: opencv, 變量值 : D:\Program Files\opencv\build
在用戶變量中選擇"path"(不區分大小寫)，點擊“編輯”，在其末尾添加 ';D\Program Files\opencv\build\x86\vc12\bin',這里分號不能省略
如果用戶變量中沒有"path"，則新建變量:"path"，變量值:'D:\Program Files\opencv\build\x86\vc12\bin'
注：無論你是64位還是32位系統，上面路徑都使用x86
至此環境變量配置完畢。此時需重啟電腦或注銷電腦，使環境變量生效。
編寫屬性表
打開記事本，分別創建兩個文本"opencvdebug.props"和"opencvrelease.props",其中對應的內容如下，可以直接拷貝過去，但注意其中‘IncludePath’和“LibraryPath”中的“D:\Program Files”要修改為自己opencv安裝路徑。

配置VS2013
打開VS2013，文件 -> 新建 -> 項目，新建控台應用程序test
分別添加上兩步創建的屬性表
此處添加"opencvdebug.props"
此處添加"opencvrelease.props"
OK,VS2013現在就配置好了，寫一個例子試驗一下
測試
在源文件寫入下面代碼，你可以復制過去
- #include<cv.h>
- #include<highgui.h>
- int main(int argc, char** argv[])
- {
- IplImage* src = cvLoadImage("F:\\Programming\\C#\\Others\\test\\test\\timg.jpg", CV_LOAD_IMAGE_GRAYSCALE);
- cvNamedWindow("Src", CV_WINDOW_AUTOSIZE);
- cvShowImage("Src", src);
- cvWaitKey(0);
- cvReleaseImage(&src);
- cvDestroyAllWindows();
- return 0;
- }
其中圖片路徑自己選擇。
結果：
之后再每次使用opencv創建工程之后分別將上述兩個屬性表導入就可以了。
