ubuntu16.04下基于opencv 3.4.1实现stereo-bm算法的双目视图的视差图

环境

ubuntu16.04LTS

算法：BM

    IplImage * img2 = cvLoadImage("../Art/view5.png",0);

    BMState->speckleRange=32; 
    BMState->disp12MaxDiff=-1; 
    CvMat* disp=cvCreateMat(img1->height,img1->width,CV_16S); 
    CvMat* vdisp=cvCreateMat(img1->height,img1->width,CV_8U); 
    int64 t=getTickCount(); 
    cvFindStereoCorrespondenceBM(img1,img2,disp,BMState); 
    t=getTickCount()-t; 
    cout<<"Time elapsed:"<

注意事项

要修改opencv库版本，比如当前open3.4.1安装在如下

/usr/local/opencv3.4.1

那么使用pkg-config

pkg-config --cflag opencv                 查看头文件路径
pkg-config --libs opencv                  查看库名
pkg-config --modversion opencv            查看版本

gedit ~/.bashrc
CMAKE_INSTALL_PREFIX=/usr/local/opencv3.4.1
export PKG_CONFIG_PATH=/usr/local/opencv3.4.1/lib/pkgconfig
export LD_LIBRARY_PATH=/usr/local/opencv3.4.1/lib

编译：

g++ `pkg-config opencv --cflags` stereo-bm.cpp -o opencv `pkg-config opencv --libs`
