如何将OpenCv3.1.0库包含和使用到CUDA文件(.cu)中? [英] How to include and use OpenCv3.1.0 library to CUDA file(.cu)?

问题描述

我试图将自己的内核实现为中值过滤器，例如伪代码:

I tried to implement my own kernel to median filter like this pseudo code:

//main.cpp
#include "opencv2/opencv.hpp"
cv::Mat inputMat = cv::imread()
cudaMedianCaller (inputMat, kernelMat)

//medianFilter.h
#include "opencv2/opencv.hpp"
cudaMedianCaller (const cv::Mat& inputMat, cv::Mat& kernelMat);

//medianFilter.cu
cudaMedianCaller (const cv::Mat& inputMat, cv::Mat& kernelMat)
{
    kernelMedianFilter<<< , >>> (uchar3* d_inputMat, uchar* d_kernelMat)
}

__global__ void kernelMedianFilter (uchar3* d_inputMat, uchar* d_kernelMat)
{

}

我得到编译错误:

C1083:无法打开包含文件:'opencv2/opencv.hpp':无此类文件或 目录

C1083: cannot open include file:'opencv2/opencv.hpp' : No such file or directory

我知道.cu文件可以用nvcc编译，而不能编译OpenCV头文件.

I know that .cu file compile with nvcc and could not compile OpenCV header filess.

推荐答案

您无需在.cu文件中包含OpenCV.您需要使用原始指针和基本数据类型作为参数的Caller API.

You don't need to include OpenCV in .cu file. You need a Caller API with raw pointers and basic data types as parameters.

main.cpp

#include "opencv2/opencv.hpp"
#include "medianFilter.h"

int main() {
  cv::Mat inputMat = cv::imread();
  .....
  cudaMedianCaller (d_inputMat, d_kernelMat);
  .....
  return 0;
}

medianFilter.h

medianFilter.h

cudaMedianCaller (uchar3* d_inputMat, uchar* d_kernelMat);

medianFilter.cu

medianFilter.cu

cudaMedianCaller (uchar3* d_inputMat, uchar* d_kernelMat)
{
    kernelMedianFilter<<< , >>> (uchar3* d_inputMat, uchar* d_kernelMat)
}

__global__ void kernelMedianFilter (uchar3* d_inputMat, uchar* _kernelMat)
{

}
