OpenCV GPU程序未运行

Question

这是我的第一篇文章。所以请原谅我，如果我不做一个完美的。

我使用OpenCV大约2个月，现在我想从GPU处理开始。于是我将OpenCV 2.4.3的新副本解压到不同的位置，并使用CMake和CUDA支持来构建它。我使用CUDA 4.2 Toolkit和SDK，然后构建它。然后，我按照其他许多帖子中的描述，以完美的方式设置环境变量和include，目录和二进制属性。但是，当我将gpu代码添加到我的项目中时，例如stereo_match.cpp，我可以成功编译和构建它们，但是当我运行它们时，没有任何结果。我只是得到一个黑色的屏幕，说：

“用法：stereo_match_gpu --left --right＃必须予以纠正--method＃BM | BP | CSBP --ndisp＃差距层数”

和该程序退出。我尝试阅读代码，但无法找到应该输入图像的位置。我在CUDA中总是noob。所以有人可以告诉我，如果我在这里做错了什么。我正在按照何种方法构建和运行GPU代码？你能否建议我去哪里错了？我正在使用Visual Studio Ultimate 32位与OpenCV 2.4.3。 GPU是NVIDIA GeForce 525M。

附加信息：当我运行内置的代码，我在控制台中执行以下操作：

Answer 1

我认为错误消息只是说，你有一些参数的程序，它告诉传递它在哪里可以找到图像。首先，您需要2张矫正图像，例如left.jpg和right.jpg。然后你必须指示Visual Studio在启动它时传递正确的参数。有关传递参数的信息，请参见here。

你需要的参数是大概就像

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

注意，我取代<left-view>和<right-view>与实际图像的名字，剥夺解释每个参数（# comments start with hash）的意见，并选择了其他参数的一些明智的选择。

请注意，如果您只是提供文件名，则文件必须与VS用于启动可执行文件的工作目录位于同一目录中。如果您愿意，您也可以提供相对路径或完整路径，或者可能告诉VS将您的图像文件夹用作工作目录。
