3.安装opencv

1. 下载opencv
2. 添加环境变量：我的安装路径为D:\ProgramFiles\opencv-3.4.10\opencv\build\x64\vc14\bin
   

4.darknet工程配置

1. 下载darknet工程https://github.com/AlexeyAB/darknet
2. 配置工程
   修改 build\darknet\darknet.vcxproj，用Notepad打开，修改两处的"CUDA 10.0，改为你自己的CUDA版本
   2.1. 找到opencv_world3xx.dll 和 opencv_ffmpeg3xx_64.dll（\opencv\build\x64\vc14\bin）将他放到\build\darknet\x64。
   2.2. 找到cudnn64_7.dll 复制到\build\darknet\x64
   2.3. \darknet.sln -> (right click on project) -> properties -> CUDA C/C++ -> Device and remove there ;compute_75,sm_75，在打开工程的时候如果提示重定向，选择确定
   
   2.4 工程中选择x64
   
   2.5 配置opencv
   (right click on project) -> properties -> C/C++ -> General -> Additional Include Directories:
   D:\ProgramFiles\opencv-3.4.10\opencv\build\include
   (right click on project) -> properties -> Linker -> General -> Additional Library Directories:
   D:\ProgramFiles\opencv-3.4.10\opencv\build\x64\vc14\lib
   2.6 最终配置
   (right click on project) -> properties -> C/C++ -> General -> Additional Include Directories, put here:
   D:\ProgramFiles\opencv-3.4.10\opencv\build\include;…\3rdparty\include;%(AdditionalIncludeDirectories);$(CudaToolkitIncludeDir);$(CUDNN)\include

(right click on project) -> properties -> Linker -> General -> Additional Library Directories, put here:
D:\ProgramFiles\opencv-3.4.10\opencv\build\x64\vc14\lib;$(CUDA_PATH)\lib$(PlatformName);$(CUDNN)\lib\x64;%(AdditionalLibraryDirectories)

(right click on project) -> properties -> Linker -> Input -> Additional dependecies, put here:
…\3rdparty\lib\x64\pthreadVC2.lib;cublas.lib;curand.lib;cudart.lib;cudnn.lib;%(AdditionalDependencies)

(right click on project) -> properties -> C/C++ -> Preprocessor -> Preprocessor Definitions
OPENCV;_TIMESPEC_DEFINED;_CRT_SECURE_NO_WARNINGS;_CRT_RAND_S;WIN32;NDEBUG;_CONSOLE;_LIB;%(PreprocessorDefinitions)

将这四个文件拷贝到C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\v140\BuildCustomizations

常见错误

more than one instance of overloaded function “_malloc_dbg” has “C” linkage.
将"Multi-threaded Debug DLL (/MDd)" 改成 “Multi-threaded DLL (/MD)”
