OpenCV 3.0错误包括ocl.hpp

Question

我在ubuntu14.04中使用opencv 3.0.0。我安装了AMD催化剂视频驱动程序来使用OpenCV和OpenCL。

/etc/OpenCL/供应商有"amdocl32.icd amdocl64“和"libamdocl32.so”和"libamdocl64.so“。

在opencv cmake文件中，OpenCV显示为：

--   OpenCV modules:
--     To be built:                 hal core flann imgproc ml photo video imgcodecs shape videoio highgui objdetect superres ts features2d calib3d stitching videostab

--     Use AMDBLAS:                 NO
--     Use OpenCL:                  YES

当我在我的projet中包含ocl.hpp文件时(#include )。编译器返回他的消息：

In file included from main.cpp:11:0:
/usr/include/opencv2/ocl/ocl.hpp: In member function ‘cv::ocl::Hamming::ResultType cv::ocl::Hamming::operator()(const unsigned char*, const unsigned char*, int) const’:

我需要在GPU上测试腐蚀和膨胀滤光片。

有人知道为什么会发生这种事吗？

您不应该将ocl.hpp包含到基于OpenCV 3.0的项目中，因为使用ocl::function_name表示法。

编辑：在OpenCV 3.0中有另一个ocl.hpp -它的含义与2.4分支完全不同:在后一种情况下，有所有opencl的函数定义，而在OpenCV 3.0中，它是与平台、上下文和设备相关的信息或调优。它可以包含在以下命令中：

#include <opencv2/core/ocl.hpp>

您的ocl.hpp来自/usr/include/ --您的系统中似乎也安装了一些OpenCV 2.4.x开发包--这是一个不同的分支，为了更好地清除，请删除所有libopencv*-dev包。如果您只想使用3.0版本，它将帮助您(移除模糊的标头)。

您应该在cmake <your opencv 3.0 source dir>和make之后运行cmake <your opencv 3.0 source dir>--它将把所有必要的东西安装到您的系统中。默认情况下，所有标头都在/usr/local/include文件夹中。
