Visual Studio 2012搭配OpenCV2.4.7

前言：
使用了Visual Studio 2012 Ultimate搭配OpenCV版本2.4.7。

軟體：
作業系統：Windows 7 旗艦版 (64位元)
Visual Studio：2012 Ultimate
OpenCV：2.4.7 (https://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.7/OpenCV-2.4.7.exe/download)

設定：
1.設定環境變數，新增以下兩條路徑。
C:\opencv\build
C:\opencv\build\x64\vc11\bin

2. 建立Win32主控台應用程式
2.1.下一步
2.2.其他選項→空選項方框打勾→完成
 
3.專案屬性
3.1. VC++目錄→Include目錄，加入
C:\opencv\build\include
C:\opencv\build\include\opencv

3.2. VC++目錄→程式庫目錄，加入
C:\opencv\build\x64\vc11\lib
3.3. 連結器→輸入→其他相依性，加入
opencv_calib3d247d.lib
opencv_contrib247d.lib
opencv_core247d.lib
opencv_features2d247d.lib
opencv_flann247d.lib
opencv_gpu247d.lib
opencv_highgui247d.lib
opencv_imgproc247d.lib
opencv_legacy247d.lib
opencv_ml247d.lib
opencv_nonfree247d.lib
opencv_objdetect247d.lib
opencv_ocl247d.lib
opencv_photo247d.lib
opencv_stitching247d.lib
opencv_superres247d.lib
opencv_video247d.lib
opencv_videostab247d.lib
3.4. 組態管理員→使用中的方案平台→新增→x64→確定

使用範例：
