c++ - opencv立体视觉深度图，代码不起作用

Question

我正在研究立体视觉深度图，我正在使用 opencv 库。我编写了一个程序来获取深度图。但是当程序运行时，我得到了一个空的深度图框。有人能帮帮我吗，出了什么问题？代码如下所示；

#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <stdio.h>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <math.h>
#include <opencv2/calib3d/calib3d.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/contrib/contrib.hpp>
int main()
{
IplImage* img1 = cvLoadImage("/home/sezen/Masaüstü/imR.png");
IplImage* img2 = cvLoadImage("/home/sezen/Masaüstü/imL.png");

IplImage *rimage = cvCreateImage(
cvSize( img1->width, img1->height ), IPL_DEPTH_8U, 1 );
cvCvtColor( img1, rimage, CV_RGB2GRAY );

IplImage *limage = cvCreateImage(
cvSize( img2->width, img2->height ), IPL_DEPTH_8U, 1 );
cvCvtColor( img2, limage, CV_RGB2GRAY );

cvNamedWindow( "Right", CV_WINDOW_AUTOSIZE );
cvShowImage( "Right", rimage );

cvNamedWindow( "Left", CV_WINDOW_AUTOSIZE );
cvShowImage("Left", limage);

CvMat *matr = cvCreateMat(rimage->height,rimage->width,CV_8UC1 );
CvMat *matl = cvCreateMat(limage->height,limage->width,CV_8UC1 );
CvMat* disp = cvCreateMat(rimage->height,rimage->width,CV_16S);
CvMat* vdisp = cvCreateMat(rimage->height,rimage->width,CV_16S);

cvConvert( rimage, matr );
cvConvert( limage, matl );

CvStereoBMState *BMState = cvCreateStereoBMState();
assert(BMState != 0);
BMState->preFilterSize=21;
BMState->preFilterCap=31;
BMState->SADWindowSize=21;
BMState->minDisparity=0;
BMState->numberOfDisparities=128;
BMState->textureThreshold=10;
BMState->uniquenessRatio=15;


cvFindStereoCorrespondenceBM( matr, matl, disp, BMState);
cvNormalize(disp, vdisp, 0, 255, CV_MINMAX);

cvShowImage("depthmap", vdisp);
cvWaitKey(0);
return 0;
}

这是使用 C++ API 的视差图代码。您标准化的最终图像应为 CV_8UC1 类型。

Mat img1, img2, g1, g2;
Mat disp, disp8;

img1 = imread("leftImage.jpg");
img2 = imread("rightImage.jpg");

cvtColor(img1, g1, CV_BGR2GRAY);
cvtColor(img2, g2, CV_BGR2GRAY);

StereoBM sbm;
sbm.state->SADWindowSize = 9;
sbm.state->numberOfDisparities = 112;
sbm.state->preFilterSize = 5;
sbm.state->preFilterCap = 61;
sbm.state->minDisparity = -39;
sbm.state->textureThreshold = 507;
sbm.state->uniquenessRatio = 0;
sbm.state->speckleWindowSize = 0;
sbm.state->speckleRange = 8;
sbm.state->disp12MaxDiff = 1;

sbm(g1, g2, disp);
normalize(disp, disp8, 0, 255, CV_MINMAX, CV_8U);

imshow("left", img1);
imshow("right", img2);
imshow("disp", disp8);
