Win10 Install OpenCV4.3.0 With Contrib and CUDA10.2

0.引言

因爲需要用到GPU的一些功能，重新安裝一下opencv並做一個記錄。

• cmake download.
• visual studio download.
• opencv download.
• opencv contrib download.

OpenCV下載注意分支對應.OpenCV保存路徑：D:\Program Files\opencv430

相關配置：

• win10x64
• VS2017
• NVIDIA:GeForce GTX 1050
• QT 5.11.1
• CUDA:cuda_10.2.89_441.22_win10
• cuDNN:cudnn-10.2-windows10-x64-v7.6.5.32
• opencv4.3.0 with contrib
• cmake-3.16

1.Cmake配置OpenCV

就在opencv430根目錄建build文件夾。

D:/Program Files/opencv430/opencv-4.3.0
D:/Program Files/opencv430/build

1.1.不帶contrib的配置(configure)

有幾個文件下載失敗，根據紅色部分的提示打開CMakeDownloadLog.txt裏面有下載改文件的地址，下載後將其改名字然後放到相應的目錄。

後面還有下載失敗的，所以先建個文件夾暫存下載的文件吧。

日誌文件：

根據日誌中網址下載後改名字：

#放置路徑 D:\Program Files\opencv430\opencv-4.3.0\.cache\ippicv
ippicv_2020_win_intel64_20191018_general.zip     ====改爲hash值的名字===>
879741a7946b814455eee6c6ffde2984-ippicv_2020_win_intel64_20191018_general.zip

#以下三個放置路徑 D:\Program Files\opencv430\opencv-4.3.0\.cache\ffmpeg
ffmpeg_version.cmake     ====改爲hash值的名字===>
ad57c038ba34b868277ccbe6dd0f9602-ffmpeg_version.cmake

opencv_videoio_ffmpeg.dll    ====改爲hash值的名字===>
3b094c37d270a30f0b20a0bc8d3ecafb-opencv_videoio_ffmpeg.dll

opencv_videoio_ffmpeg_64.dll    ====改爲hash值的名字===>
388ee23a7ca44eef2344e265fafd5940-opencv_videoio_ffmpeg_64.dll

再次配置就OK了！

1.2.帶contrib的配置(configure)

OPENCV_EXTRA_MODULES_PATH ： D:/Program Files/opencv430/opencv_contrib-4.3.0/modules

如果需要用 SURF，SIFT算法的話把OPENCV_ENABLE_NONFREE勾上。BUILD_opencv_world勾上，最後編譯的結果爲兩個，一個debug版本，一個release版本。

configure後依然有文件下載失敗，同樣打開CMakeDownloadLog.txt查看：

這裏網址輸入後是txt,右鍵另存爲會自動顯示保存的名稱。

根據日誌文件提示分別放入

#文件夾需要自己根據路徑建
D:\Program Files\opencv430\build\downloads\xfeatures2d
D:\Program Files\opencv430\build\testdata\cv\face

再次configure，就OK了。

我感覺上一步也可以這樣，不用改名字，放在missing路徑下就OK

configure成功後，Generate生成vs工程文件。 之後直接Open Project，則會使用前面選擇的vs版本打開工程。

2.Visual Studio編譯OpenCV

在菜單欄上選擇：生成 ->批生成。可同時編譯debug版本和release版本。
編譯完後，把build/install文件夾放到opencv430文件夾下就OK。

3.配置環境

這個就是平時遇到的操作了。

環境變量配置：此電腦右鍵屬性–>高級系統設置–>環境變量–>系統變量–>Path–>新建

D:\Program Files\opencv430\install\x64\vc15\bin

3.1.debug x64

打開VS新建一個工程，新建屬性表opencv430x64d.props

• include目錄:在通用屬性–>VC++目錄–>包含目錄中添加

D:\Program Files\opencv430\install\include
D:\Program Files\opencv430\install\include\opencv2

• lib目錄:通用屬性–>VC++目錄–>庫目錄中添加

D:\Program Files\opencv430\install\x64\vc15\lib

• 庫文件：通用屬性–>鏈接器–>輸入–>附加的依賴項中添加

opencv_img_hash430d.lib
opencv_world430d.lib

3.2.release x64

新建屬性表opencv430x64r.props

• include目錄:在通用屬性–>VC++目錄–>包含目錄中添加

D:\Program Files\opencv430\install\include
D:\Program Files\opencv430\install\include\opencv2

• lib目錄:通用屬性–>VC++目錄–>庫目錄中添加

D:\Program Files\opencv430\install\x64\vc15\lib

• 庫文件：通用屬性–>鏈接器–>輸入–>附加的依賴項中添加

opencv_img_hash430.lib
opencv_world430.lib

然後將屬性表拷貝到安裝目錄，以便後續查找。

最後，註銷一下電腦，進行測試，不需要重啓。

4.opencv430 with contrib and CUDA10.2

4.1.Cmake與VS編譯

• 爲什麼帶CUDA與不帶CUDA版本要分開編譯？

不帶CUDA版本的opencv方便拷貝到其他電腦使用，同時拷貝install文件夾和屬性表，按照安裝目錄放置就OK，只需要配置一個環境變量就可以直接使用了，很方便。但是帶CUDA的版本就不一樣了，需要CUDA版本相同，稍微麻煩一點，同時爲了降低出錯率，選擇分開編譯。

• win10安裝opencv

將上面編譯好的文件夾opencv430複製一份，並改名爲opencv430withCUDA。將build文件夾裏面的testdata與downloads保留，其他的刪除，將opencv-4.3.0\.cacha\ffmpeg與ippicv保留，其他的刪除，保留的就是上面自己下載的文件。

打開CMake，點擊File-->Delete Cache重新輸入路徑。

D:/Program Files/opencv430withCUDA/opencv-4.3.0
D:/Program Files/opencv430withCUDA/build

D:/Program Files/opencv430withCUDA/opencv_contrib-4.3.0/modules

需要勾選的選項有：

BUILD_opencv_world 
OPENCV_ENABLE_NONFREE
WITH_CUDA
MKL_WITH_OPENMP  #這是一個並行加速庫，可以不選，只是我需要用
OPENCV_DNN_CUDA
WITH_TBB    #默認情況下是OFF、勾選可以獲得並行處理支持
CUDA_ARCH_BIN  6.1 #刪除其他的數字，這個6.1是顯卡計算力，根據自己的顯卡填寫，就是這裏十分耗時

按照上面的流程走一遍，下載失敗的文件都已經下載了，只要CUDA安裝沒出錯就比較快 ，帶CUDA 的編譯好慢！！流程上沒什麼大問題，就是VS編譯很慢。

configure完成後，Open Project打開工程：生成–>批生成。把install文件夾拷貝出來。

4.2.環境配置

環境變量配置：此電腦右鍵屬性–>高級系統設置–>環境變量–>系統變量–>Path–>新建

D:\Program Files\opencv430withCUDA\install\x64\vc15\bin

註銷一下電腦，或者全部配置完後再註銷。

4.2.1.debug x64

打開VS新建一個工程，新建屬性表opencv430x64d.props

• include目錄:在通用屬性–>VC++目錄–>包含目錄中添加

D:\Program Files\opencv430WithCUDA\install\include
D:\Program Files\opencv430withCUDA\install\include\opencv2

• lib目錄:通用屬性–>VC++目錄–>庫目錄中添加

D:\Program Files\opencv430withCUDA\install\x64\vc15\lib

如果前面沒有勾選BUILD_opencv_world，庫文件會比較多，此時庫文件的名稱可以使用命令行獲取，區別於Linux的命令行，Windows的腳本可以使用後綴名爲**.bat的文件:

cd  D:\Program Files\opencv430withCUDA\install\x64\vc15\lib
dir /b *430d.lib  >DebugLibName.txt && move  "DebugLibName.txt"  "D:\Program Files\opencv430withCUDA\DebugLibName.txt"
dir /b *430.lib  >ReleaseLibName.txt && move  "ReleaseLibName.txt"  "D:\Program Files\opencv430withCUDA\ReleaseLibName.txt"

雙擊運行後在D:\Program Files\opencv430withCUDA\中打開txt文檔複製就好。

• 庫文件：通用屬性–>鏈接器–>輸入–>附加的依賴項中添加

opencv_img_hash430d.lib
opencv_world430d.lib

4.2.2.release x64

新建屬性表opencv430x64r.props

• include目錄:在通用屬性–>VC++目錄–>包含目錄中添加

D:\Program Files\opencv430WithCUDA\install\include
D:\Program Files\opencv430withCUDA\install\include\opencv2

• lib目錄:通用屬性–>VC++目錄–>庫目錄中添加

D:\Program Files\opencv430withCUDA\install\x64\vc15\lib

• 庫文件：通用屬性–>鏈接器–>輸入–>附加的依賴項中添加

opencv_img_hash430.lib
opencv_world430.lib

最後將屬性表拷貝到安裝目錄，以便後續查找。

安裝好後可以刪除opencv430和opencv430withCUDA下的build文件夾。很大。註銷一下電腦，進行測試，不需要重啓。

	surf.downloadKeypoints(keypoints1GPU, keypoints1);
	surf.downloadKeypoints(keypoints2GPU, keypoints2);
	surf.downloadDescriptors(descriptors1GPU, descriptors1);
	surf.downloadDescriptors(descriptors2GPU, descriptors2);
 
	// drawing the results
	Mat img_matches;
	drawMatches(Mat(img1), keypoints1, Mat(img2), keypoints2, matches, img_matches);
 
	namedWindow("matches", 0);
	imshow("matches", img_matches);
	waitKey(0);
 
	return 0;
}

安裝完測試時報錯,無法定位程序輸入點於動態庫上：

很顯然庫沒找到！在路徑D:\Program Files\opencv430withCUDA\install\x64\vc15下有兩個文件夾，一個bin,一個lib,從前面的配置可以看到，bin文件路徑是添加到環境變量的，lib路徑是添加到屬性表裏面的。其中bin裏面是動態庫dll和可執行文件exe，lib裏面就是靜態庫。所以，如果是lib庫沒找到，那就是庫目錄，和庫名稱的問題；如果是動態庫dll文件沒找到，那就是環境變量的問題。但是環境變量已經設置了，那就真像只有一個，環境變量的順序問題！！因爲前面已經添加了不帶CUDA版本的環境變量，這次添加的環境變量在其之後，故找錯了庫所以報錯。

順便查了一下可執行文件在運行時尋找和調用dll文件的路徑搜索順序。一般是：

• A 可執行文件所在目錄；
• B 進程當前目錄；
• C 系統目錄，%SystemRoot%/system32
• D 16位系統目錄；，%SystemRoot%/system
• E Windows目錄，%SystemRoot%/
• F 環境變量PATH中的目錄；

移動順序後，成功運行：

編譯多個版本可能就會存在動態庫查找順序的問題，自己得清楚版本之間的差別在哪兒，遇到報錯能反應過來。enjoy.
