網頁是 https://opencv.org/releases.html

裡面會有各個版本的

樓主下了 2.4.13.6版本的

在環境變數的系統變數的path中新增路徑：（x86和x64我覺得就是64位和32位的意思）

D:\OpenCV2.4.13.6\opencv\build\x64\vc14\bin

然後進入VS2015

新建控制檯應用程式 後，新增屬性表

（屬性管理器視窗可以在 檢視->其他視窗  中調用出來）

命名：

於是就有了

右鍵其，選擇->屬性     在彈出來的視窗中如下選擇  按  “包含目錄”

新增以下三個目錄：

D:\OpenCV2.4.13.6\opencv\build\include

D:\OpenCV2.4.13.6\opencv\build\include\opencv

D:\OpenCV2.4.13.6\opencv\build\include\opencv2

接下來編輯  庫目錄：

新增：

D:\OpenCV2.4.13.6\opencv\build\x64\vc14\lib

然後新增附加依賴項
【連結器】-->【輸入】-->【附加依賴項】，在附加依賴項裡新增庫檔案

opencv_ml2413d.lib

opencv_calib3d2413d.lib

opencv_contrib2413d.lib

opencv_core2413d.lib

opencv_features2d2413d.lib

opencv_flann2413d.lib

opencv_gpu2413d.lib

opencv_highgui2413d.lib

opencv_imgproc2413d.lib

opencv_legacy2413d.lib

opencv_objdetect2413d.lib

opencv_ts2413d.lib

opencv_video2413d.lib

opencv_nonfree2413d.lib

opencv_ocl2413d.lib

opencv_photo2413d.lib

opencv_stitching2413d.lib

opencv_superres2413d.lib
