使用opencv的视频稳定 [英] video stabilization using opencv

问题描述

我试图用opencv（没有opencv视频稳定类）进行视频稳定。

I am trying to do video stabilization with opencv(without the opencv video stabilization class).

我的算法的步骤如下 - >

the steps for my algo is as follows->

1. 冲浪点提取，

1. Surf points extraction,

匹配

同质性矩阵，

warpPerspective

warpPerspective

输出视频不稳定，它只是看起来像原来的视频，我找不到和参考代码的视频稳定我按照描述这里。任何人都可以帮助我告诉我在哪里我错了或提供我一些源代码链接

And the output video is not stabilized at all :(. it just looks like the original video. I could not find and reference code for video stabilization. I followed the procedure described here . Can anybody help me out by telling me where I am going wrong or provide me some source code link to improve my algo.

请帮助。

推荐答案

您可以使用我的代码段作为起点（不是很稳定，但似乎它的工作原理）：

You can use my code snippet as a start point (not very stable but seems it works):

#include "opencv2/opencv.hpp"
#include <iostream>
#include <vector>
#include <stdio.h>

using namespace cv;
using namespace std;

int main(int ac, char** av)
{
    VideoCapture capture(0);
    namedWindow("Cam");
    namedWindow("Camw");
    Mat frame;
    Mat frame_edg;
    Mat prev_frame;
    int k=0;
    Mat Transform;
    Mat Transform_avg=Mat::eye(2,3,CV_64FC1);
    Mat warped;
    while(k!=27)
    {
        capture >> frame;
        cv::cvtColor(frame,frame,cv::COLOR_BGR2GRAY);
        cv::equalizeHist(frame,frame);
        cv::Canny(frame,frame_edg,64,64);
        //frame=frame_edg.clone();
        imshow("Cam_e",frame_edg);
        imshow("Cam",frame);

        if(!prev_frame.empty())
        {
            Transform=estimateRigidTransform(frame,prev_frame,0);
            Transform(Range(0,2),Range(0,2))=Mat::eye(2,2,CV_64FC1);
            Transform_avg+=(Transform-Transform_avg)/2.0;
            warpAffine(frame,warped,Transform_avg,Size( frame.cols, frame.rows));

            imshow("Camw",warped);
        }

        if(prev_frame.empty())
        {
            prev_frame=frame.clone();
        }

        k=waitKey(20);      
    }
    cv::destroyAllWindows();
    return 0;
}

您也可以寻找纸：Chen_Halawa_Pang_FastVideoStabilization.pdf as remeber there are MATLAB源代码。

You can also look for paper: Chen_Halawa_Pang_FastVideoStabilization.pdf as I remeber there was MATLAB source code supplied.
