Question

这是我的第一篇文章。所以，请原谅我，如果我不把它变成一个完美的。

我使用OpenCV大约2个月，现在我想开始GPU处理。因此，我将OpenCV 2.4.3的新副本解压缩到不同的位置，并使用CMake和CUDA支持来进行补充。我使用CUDA 4.2 Toolkit和SDK然后构建它。然后我以完美的方式设置环境变量和include，目录和二进制属性，如此处的许多其他帖子所述。

然而，当我向我的项目添加一个gpu代码时，例如stereo_match.cpp，我能够成功编译和构建它们，但是当我运行它们时，没有结果。我只是得到一个黑屏，上面写着：

“用法：stereo_match_gpu --left --right＃必须纠正 - 方法#BB | BP | CSBP --ndisp＃disparity levels of number”

然后程序退出。我尝试阅读代码但无法找到我应该在哪里提供输入图像。我是CUDA的总菜鸟。所以有人可以告诉我，如果我在这里做错了什么。我正在遵循的方法来构建和运行GPU代码吗？你能告诉我哪里出错吗？我在OpenCV 2.4.3中使用Visual Studio Ultimate 32位。 GPU是NVIDIA GeForce 525M。

附加信息：当我运行构建的代码时，我在控制台中获得以下内容：

我认为错误信息只是说你必须将一些参数传递给程序，告诉它在哪里找到图像。首先，您需要2个经过纠正的图像，例如left.jpg和right.jpg。然后，您必须指示Visual Studio在启动时向程序传递正确的参数。有关传递参数的信息，请参阅here。

您需要的参数可能类似于

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

请注意，我将<left-view>和<right-view>替换为实际图片名称，删除了解释每个参数（# comments start with hash）的注释，并为其他参数选择了一些明智的选项。

请注意，如果您只提供文件名，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将图像文件夹用作工作目录。
