OpenCV/Android 编译错误

发布于 2024-11-17 09:59:32 字数 1194 浏览 1 评论 0原文

我目前正在关注本教程（http://www.stanford.edu/class/ee368/Android/Tutorial-2-OpenCV-for-Android-Setup-Windows.pdf），了解如何在 Windows 中设置 OpenCV for Android 和我有一些我不明白的错误。基本上，在步骤 3.c 中，当我使用命令“make”在 Cygwin 中编译 OpenCV 库时，我收到这些错误；

/home/Ralph/opencv/modules/legacy/src/calibfilter.cpp: In member function `virtual bool CvCalibFilter::SaveCameraParams(const char*)':
/home/Ralph/opencv/modules/legacy/src/calibfilter.cpp:693: error: `struct CvStereoCamera' has no member named `quad'
/home/Ralph/opencv/modules/legacy/src/calibfilter.cpp:694: error: `struct CvStereoCamera' has no member named `quad'
/home/Ralph/opencv/modules/legacy/src/calibfilter.cpp: In member function `virtual bool CvCalibFilter::LoadCameraParams(const char*)':
/home/Ralph/opencv/modules/legacy/src/calibfilter.cpp:749: error: `struct CvStereoCamera' has no member named `quad'
/home/Ralph/opencv/modules/legacy/src/calibfilter.cpp:750: error: `struct CvStereoCamera' has no member named `quad'
make[2]: *** [modules/legacy/CMakeFiles/opencv_legacy.dir/src/calibfilter.o] Error 1
make[1]: *** [modules/legacy/CMakeFiles/opencv_legacy.dir/all] Error 2
make: *** [all] Error 2

提前感谢您的帮助，

拉尔夫。

I am currently following this tutorial (http://www.stanford.edu/class/ee368/Android/Tutorial-2-OpenCV-for-Android-Setup-Windows.pdf) on how to set up OpenCV for Android in Windows and I am having some errors that I do not understand. Basically, at the step 3.c, when I compile the OpenCV libraries in Cygwin using the command “make”, I get these errors;

/home/Ralph/opencv/modules/legacy/src/calibfilter.cpp: In member function `virtual bool CvCalibFilter::SaveCameraParams(const char*)':
/home/Ralph/opencv/modules/legacy/src/calibfilter.cpp:693: error: `struct CvStereoCamera' has no member named `quad'

Thank you for your help in advance,

calibfilter.cpp 和 epilines.cpp 的顶部都有一个“#undefquad”。如果我注释掉这些undef，它就会成功编译。

对于我的一生，我无法弄清楚为什么那里有一个 undef...也许导入的顺序是错误的或者其他什么。

我遇到了同样的问题。查看/home/Ralph/opencv/modules/legacy/include/opencv2/legacy/legacy.hpp，结构定义是：

typedef struct CvStereoCamera
{
    CvCamera* camera[2]; /* two individual camera parameters */
    float fundMatr[9]; /* fundamental matrix */

    /* New part for stereo */
    CvPoint3D32f epipole[2];
    CvPoint2D32f quad[2][4]; /* coordinates of destination quadrangle after
                                epipolar geometry rectification */
    double coeffs[2][3][3];/* coefficients for transformation */
    CvPoint2D32f border[2][4];
    CvSize warpSize;
    CvStereoLineCoeff* lineCoeffs;
    int needSwapCameras;/* flag set to 1 if need to swap cameras for good reconstruction */
    float rotMatrix[9];
    float transVector[3];
} CvStereoCamera;

我完全困惑为什么它似乎没有work:quad 就在那里定义的。

通过注释 calibfilter.cpp 和 epilines.cpp 中引用 quad 属性的所有行，我至少设法让 OpenCV 编译，但是这个毫无疑问打破了立体摄像头的支持。

I've run into the same problem. Looking into /home/Ralph/opencv/modules/legacy/include/opencv2/legacy/legacy.hpp, the struct definition is:

typedef struct CvStereoCamera
{
    CvCamera* camera[2]; /* two individual camera parameters */
    float fundMatr[9]; /* fundamental matrix */

    /* New part for stereo */
    CvPoint3D32f epipole[2];
    CvPoint2D32f quad[2][4]; /* coordinates of destination quadrangle after
                                epipolar geometry rectification */
    double coeffs[2][3][3];/* coefficients for transformation */
    CvPoint2D32f border[2][4];
    CvSize warpSize;
    CvStereoLineCoeff* lineCoeffs;
    int needSwapCameras;/* flag set to 1 if need to swap cameras for good reconstruction */
    float rotMatrix[9];
    float transVector[3];
} CvStereoCamera;

I'm completely puzzled as to why it then doesn't appear to work: quad is defined right there.

By commenting all lines in calibfilter.cpp and epilines.cpp that reference the quad attribute, I managed to get OpenCV at least compiling, but this has no doubt broken the stereo camera support.
