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

code

算法：BM

#include <iostream> #include <fstream> #include <stdio.h> #include <sstream> #include <time.h> //#include <opencv2/opencv.hpp> #include <opencv2/core/core.hpp> #include <opencv2/imgproc/imgproc.hpp> #include <opencv2/calib3d/calib3d.hpp> #include <opencv2/highgui/highgui.hpp> using namespace std; using namespace cv; int main() { //IplImage * img1 = cvLoadImage("left.png",0); //IplImage * img2 = cvLoadImage("right.png",0); //IplImage * img1 = cvLoadImage("tsukuba_l.png",0); //IplImage * img2 = cvLoadImage("tsukuba_r.png",0); IplImage * img1 = cvLoadImage("../Art/view1.png",0); IplImage * img2 = cvLoadImage("../Art/view5.png",0); CvStereoBMState* BMState=cvCreateStereoBMState(); assert(BMState); BMState->preFilterSize=9; BMState->preFilterCap=31; BMState->SADWindowSize=15; BMState->minDisparity=0; BMState->numberOfDisparities=144; BMState->textureThreshold=10; BMState->uniquenessRatio=5; BMState->speckleWindowSize=100; 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:"<<t*1000/getTickFrequency()<<endl; cvSave("disp.xml",disp); cvNormalize(disp,vdisp,0,255,CV_MINMAX); namedWindow("left", 1); cvShowImage("left", img1); namedWindow("right", 1); cvShowImage("right", img2); //cvNamedWindow("BM_disparity",0); namedWindow("BM_disparity", 1); cvShowImage("BM_disparity",vdisp); cvWaitKey(0); //cvSaveImage("cones\\BM_disparity.png",vdisp); cvReleaseMat(&disp); cvReleaseMat(&vdisp); cvDestroyWindow("BM_disparity"); return 0; }

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`
