Question

我正在开发一个将OpenCV链接到Scilab的图像处理工具箱，以便可以直接在Scilab中使用OpenCV函数。现在，我的问题是我有很多函数在所有其他代码中使用，所以我决定将它们包含在外部cpp文件中，并将其包含在我的其他代码中。我做的是，我用函数定义创建了一个头文件common.h。 common.c具有写入的实际功能。而我的所有其他文件，例如opencv_imcrop都有#include“common.h”以及其他包含的头文件。但是，当我使用我的构建器网关文件（编译我的opencv_imcrop.cpp的.sce文件）在Scilab中编译它时，它会出现以下错误： -

opencv_imcrop.cpp:14:22：致命错误：common.h：没有这样的文件或目录编译终止。

这是我的common.h文件： -

#include "common.cpp"

string type2str(int type);
int no_of_channels(int type);
int retrieveImage(Mat &image);
int returnImage(char *checker,int &temp,Mat img);

这是我的common.cpp文件： -

string type2str(int type) 
{
    string r;
    uchar depth = type & CV_MAT_DEPTH_MASK;
    switch ( depth )
    {
        case CV_8U:  r = "8U"; break;
        case CV_8S:  r = "8S"; break;
        case CV_16U: r = "16U"; break;
        case CV_16S: r = "16S"; break;
        case CV_32S: r = "32S"; break;
        case CV_32F: r = "32F"; break;
        case CV_64F: r = "64F"; break;
        default:     r = "User"; break;
    }
    return r;
}

int no_of_channels(int type)
{
    uchar chans = 1 + (type >> CV_CN_SHIFT);
    return chans;
}
//Note : the other 2 functions are also present here, but they
// comprise of 800 lines of code, so i did not paste them here

我的opencv_imcrop.cpp（必须包含上述使用函数的头文件的文件）文件是： -

#include <numeric>
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/opencv.hpp"
#include <iostream>
using namespace cv;
using namespace std;
extern "C"
{
  #include "api_scilab.h"
  #include "Scierror.h"
  #include "BOOL.h"
  #include <localization.h>
  #include "common.h"

  int opencv_imcrop(char *fname, unsigned long fname_len)
  {

    SciErr sciErr;
    int iRows=0,iCols=0;
    int *piAddr = NULL;
    int *piAddrNew = NULL;
    int *piAddr2  = NULL;
    int *piAddr3  = NULL;
    int *piAddr4  = NULL;
    int *piAddr5  = NULL;
    unsigned char *pstDataR = NULL;
    unsigned char *pstDataG = NULL;
    unsigned char *pstDataB = NULL;
    int i,j,k;
    double *x,*y,*width,*height;

    //checking input argument
    CheckInputArgument(pvApiCtx, 5, 5);
    CheckOutputArgument(pvApiCtx, 1, 1) ;

    Mat image;
    retrieveImage(image);

    //for value of top-left x-coordinate
    sciErr = getVarAddressFromPosition(pvApiCtx,2,&piAddr2);
    if (sciErr.iErr)
    {
        printError(&sciErr, 0);
        return 0;
    }
    sciErr = getMatrixOfDouble(pvApiCtx, piAddr2, &iRows, &iCols ,&x);
    if(sciErr.iErr)
    {
        printError(&sciErr, 0);
        return 0;
    }   

    //for value top-left y-coordinate
    sciErr = getVarAddressFromPosition(pvApiCtx,3,&piAddr3);
    if (sciErr.iErr)
    {
        printError(&sciErr, 0);
        return 0;
    }
    sciErr = getMatrixOfDouble(pvApiCtx, piAddr3, &iRows, &iCols ,&y);
    if(sciErr.iErr)
    {
        printError(&sciErr, 0);
        return 0;
    }

    //for value of width
    sciErr = getVarAddressFromPosition(pvApiCtx,4,&piAddr4);
    if (sciErr.iErr)
    {
        printError(&sciErr, 0);
        return 0;
    }
    sciErr = getMatrixOfDouble(pvApiCtx, piAddr4, &iRows, &iCols ,&width);
    if(sciErr.iErr)
    {
        printError(&sciErr, 0);
        return 0;
    }   

    //for value of height
    sciErr = getVarAddressFromPosition(pvApiCtx,5,&piAddr5);
    if (sciErr.iErr)
    {
        printError(&sciErr, 0);
        return 0;
    }
    sciErr = getMatrixOfDouble(pvApiCtx, piAddr5, &iRows, &iCols ,&height);
    if(sciErr.iErr)
    {
        printError(&sciErr, 0);
        return 0;
    }   

    //defining a temporary rectangle, that denotes the area that has to be cropped into the new image
    Rect myROI(x[0], y[0], width[0], height[0]);

    // Crop the full image to that image contained by the rectangle myROI
    // Note that this doesn't copy the data
    Mat croppedRef(image, myROI);

    Mat cropped;
    // Copy the data into new matrix
    croppedRef.copyTo(cropped);

    int temp = nbInputArgument(pvApiCtx) + 1;
    string tempstring = type2str(cropped.type());
    char *checker;
    checker = (char *)malloc(tempstring.size() + 1);
    memcpy(checker, tempstring.c_str(), tempstring.size() + 1);
    returnImage(checker,temp,cropped);

    //Assigning the list as the Output Variable
    AssignOutputVariable(pvApiCtx, 1) = nbInputArgument(pvApiCtx) + 1;
    //Returning the Output Variables as arguments to the Scilab environment
    ReturnArguments(pvApiCtx);
    return 0;

  }
/* ==================================================================== */
}

最后，我在scilab中执行的.sce（builder_gateway_cpp.sce）文件编译上面的cpp文件如下： -

function builder_gw_cpp()
    WITHOUT_AUTO_PUTLHSVAR = %t;
tbx_build_gateway("skeleton_cpp69690", ..
    ["imcrop","opencv_imcrop"], ..
    ["opencv_imcrop.cpp"], ..


    get_absolute_file_path("builder_gateway_cpp.sce"),[],"g++ -ggdb
 `pkg-config --cflags opencv` -o `basename opencv_imcrop.cpp .cpp`
 opencv_imcrop.cpp `pkg-config --libs opencv`");

endfunction

builder_gw_cpp();
clear builder_gw_cpp; // remove builder_gw_cpp on stack

在OpenCV cpp代码中包含外部cpp文件
