如何在Ubuntu 11.10上使用CUDA和OpenCV？

Question

我希望在Ubuntu上运行Surfgpu，但不知道如何编写Cmakelists。我已经安装了CUDA 4.2 SDK和Toolkit，并且程序中的C语言可以运行。我的开发环境是Qt。Ubuntu 11.10.Opencv2.4.2。

如果您有好的建议，请告诉我。谢谢！

Answer 1

这个怎么样？

# CMakeLists.txt to build OpenCV project
cmake_minimum_required(VERSION 2.8)
project( testOpenCV )

查找OpenCV和CUDA软件包

find_package(OpenCV REQUIRED )
find_package(CUDA 4.2 REQUIRED)

从一些目录中包含

# Since surf is a non free package, you also have to add non free include dir
include_directories( ${OpenCV_INCLUDE_DIR} "${OpenCV_SOURCE_DIR}/modules/nonfree/include" ${CUDA_INCLUDE_DIRS})

编译源代码

cuda_add_executable( exefile source.cpp source2.cpp )
target_link_libraries( exefile ${OpenCV_LIBS} ${otherlibsyouneed} )

所有上述内容仅在您使用-DHAVE_CUDA编译OpenCV时才有效。
