OpenCV GPU程序未运行

Question

这是我的第一篇文章。 所以，请原谅我，如果我没有使它成为一个完美的。

我正在使用OpenCV大约2个月，现在我想开始进行GPU处理。 因此，我将OpenCV 2.4.3的新副本解压缩到其他位置，并使用带有CUDA支持的CMake来构建它。 我使用CUDA 4.2工具包和SDK，然后在构建它时使用。 然后，如本文其他许多文章所述，以一种完美的方式设置环境变量并包括目录和二进制属性。

但是，当我向项目中添加gpu代码（例如，stereo_match.cpp）时，我能够成功编译并构建它们，但是当我运行它们时，没有任何结果。 我只是得到一个黑屏，上面写着：

“用法：stereo_match_gpu --left --right＃必须纠正--method＃BM | BP | CSBP --ndisp＃视差等级数”

程序退出。 我尝试阅读代码，但找不到应该在哪里提供输入图像。 我完全是CUDA的菜鸟。 所以有人可以告诉我我在这里做错了什么吗。 我遵循的构建和运行GPU代码的方法正确吗？ 您能建议我要去哪里了吗？ 我在OpenCV 2.4.3中使用Visual Studio Ultimate 32位。 GPU是NVIDIA GeForce 525M。

附加信息：运行构建的代码时，在控制台中得到以下信息：

我认为错误消息只是在说您必须将一些参数传递给程序，该参数告诉程序在哪里可以找到图像。 首先，你需要2张整流图片，说left.jpg和right.jpg 。 然后，您必须指示Visual Studio在启动程序时为其传递正确的参数。 有关传递参数的信息，请参见此处 。

您需要的参数可能类似于

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

请注意，我用实际的图像名称替换了<left-view>和<right-view> ，剥离了解释每个参数的注释（ # comments start with hash ），并为其他参数选择了一些明智的选择。

请注意，如果仅提供文件名，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。 您也可以根据需要提供相对路径或完整路径，或者可能告诉VS使用图像所在的文件夹作为工作目录。
