编译opencv与gpu cuda支持 [英] compiling opencv with gpu cuda support

问题描述

我使用OpenCV 2.3.1与CUDA 4.0。

我已经安装了OpenCV 2.3.1通过CMAKE with WITH_CUDA标志。然后我编译的OpenCV解决方案在发布和调试模式，但仍然是当我使用 getCudaEnabledDevice 函数 CV :: GPU 它返回0.这意味着它没有检测到CUDA启用的设备。

似乎我做了一切正确，仍然发生了什么?? <

任何人都可以建议现在的问题在哪里。

解决方案

我有同样的问题。我修复它
将opencv_core243d.dll从 E：\opencv\build\gpu\x64\vc10\lib 文件夹复制到工作目录与.exe。

不知道为什么应该重要，但它是。

使用cuda 5.0

I am using OpenCV 2.3.1 with CUDA 4.0.

I have installed the OpenCV 2.3.1 by CMAKE with WITH_CUDA flag on. And then I compiled the OpenCV solution in release and debug mode, but still when I used the getCudaEnabledDevice function of CV::GPU it is returning 0. This means it is not detecting the CUDA enabled device.

It seems that I have done everything right, still what is happening??

Can Anybody suggest where can be the problem now??.

Thanks in advance.

解决方案

I had the same problem. I fixed it by copying opencv_core243d.dll from E:\opencv\build\gpu\x64\vc10\lib folder to the work directory with the .exe.
Don't know why that should matter but it did.
