OpenCV GPU程序未運行

Question

這是我的第一篇文章。所以請原諒我，如果我不做一個完美的。

我使用OpenCV大約2個月，現在我想從GPU處理開始。於是我將OpenCV 2.4.3的新副本解壓到不同的位置，並使用CMake和CUDA支持來構建它。我使用CUDA 4.2 Toolkit和SDK，然後構建它。然後，我按照其他許多帖子中的描述，以完美的方式設置環境變量和include，目錄和二進制屬性。但是，當我將gpu代碼添加到我的項目中時，例如stereo_match.cpp，我可以成功編譯和構建它們，但是當我運行它們時，沒有任何結果。我只是得到一個黑色的屏幕，說：

「用法：stereo_match_gpu --left --right＃必須予以糾正--method＃BM | BP | CSBP --ndisp＃差距層數」

和該程序退出。我嘗試閱讀代碼，但無法找到應該輸入圖像的位置。我在CUDA中總是noob。所以有人可以告訴我，如果我在這裏做錯了什麼。我正在按照何種方法構建和運行GPU代碼？你能否建議我去哪裏錯了？我正在使用Visual Studio Ultimate 32位與OpenCV 2.4.3。 GPU是NVIDIA GeForce 525M。

附加信息：當我運行內置的代碼，我在控制檯中執行以下操作：

Answer 1

我認爲錯誤消息只是說，你有一些參數的程序，它告訴傳遞它在哪裏可以找到圖像。首先，您需要2張矯正圖像，例如left.jpg和right.jpg。然後你必須指示Visual Studio在啓動它時傳遞正確的參數。有關傳遞參數的信息，請參見here。

你需要的參數是大概就像

--left left.jpg --right right.jpg --method BM --ndisp 32 

注意，我取代<left-view>和<right-view>與實際圖像的名字，剝奪解釋每個參數（# comments start with hash）的意見，並選擇了其他參數的一些明智的選擇。

請注意，如果您只是提供文件名，則文件必須與VS用於啓動可執行文件的工作目錄位於同一目錄中。如果您願意，您也可以提供相對路徑或完整路徑，或者可能告訴VS將您的圖像文件夾用作工作目錄。
