我正在运行 Ubuntu 12.04、OpenCV 2.4.6.0.1 和 Cuda 5.5 我得到以下代码：
BruteForceMatcher_GPU< Hamming > matcher;
ORB_GPU orb(1000);
GpuMat patternImage_descriptors;
orb(patternImage_g, GpuMat(), patternImage_keypoints, patternImage_descriptors);
// where patternImage_g is an image I'm loading with GpuMat patternImage_g(originalImage)
// after I make it Gray and resizeing it to 640x480
// then I call
vector<GpuMat> descriptors(1);
descriptors[0] = patternImage_descriptors;
matcher.add(descriptors);
// to train the matcher and then
vector< vector<DMatch> > matches;
matcher.match(frame_descriptors, matches);
// Where frame_descriptors were extracted via ORB_GPU
然后我得到这个编译错误：
MatchingEngineGPU.cpp: In member function 'void
MatchingEngineGPU::processFrameFromFile(const Frame&, Frame&)':
MatchingEngineGPU.cpp:28:43: error: no matching function for call to
'cv::gpu::BruteForceMatcher_GPU<cv::Hamming>::match(cv::gpu::GpuMat&,

编译命令：
g++ *.hpp *.cpp `pkg-config --cflags --libs opencv`
我检查了 BruteForceMatcher_GPU 的文档，它具有以下功能：
void match(const GpuMat& query, std::vector<DMatch>& matches,
const std::vector<GpuMat>& masks = std::vector<GpuMat>());
这可能只是一个 C++ 逻辑错误，但对于我来说，我无法弄清楚，请帮助我。
