OpenCV安裝

1 系統更新
利用ubuntu自帶的更新管理器或者
sudo apt-get update
sudo apt-get upgrade

2 安裝必要的元件
sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen3-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev default-jdk ant libvtk5-qt4-dev

3 下載opencv3.0

http://opencv.org/downloads.html

解壓到某個檔案下，這裡選擇
/home/yourname/opencv3.0

4  編譯opecv3.0
進入解壓後的opencv3.0目錄

mkdir build

進入build目錄

cd build

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

5 安裝opencv3.0

在build目錄
make
sudo make install

6 配置opencv.conf file ，加入環境變數
sudo gedit /etc/ld.so.conf.d/opencv.conf

在opencv.conf裡面加入命令
/usr/local/lib

更新庫目錄
sudo ldconfig

開啟檔案bash.bashrc
sudo gedit /etc/bash.bashrc
加入下面兩行
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH



7 測試你的opencv3.0是否安裝成功

編譯不通過請登出或者重啟電腦試試

測試程式碼：opencvtest.cpp

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace cv;

int main()
{
    Mat src = imread("test.jpg",1);
    imshow("src",src);
    waitKey(0);
    return 0;
}

注意：linux下面的目錄形式為/.../....

所以“#include <opencv2\core\core.hpp>” 會找不到標頭檔案

編譯方式：
1 命令列
g++  opencvtest.cpp -o opencvtest  `pkg-config  --cflags --libs opencv`

2 藉助cmake，寫CMakeLists.txt

cmake_minimum_required(VERSION 2.8)

project(opencvtest)

find_package( OpenCV REQUIRED )

add_executable( opencvtest opencvtest.cpp )

target_link_libraries( opencvtest ${OpenCV_LIBS} )

之後 執行

cmake .
Make
 執行
./ opencvtest


8 opnecv3.0的HDR效果測試

#include <opencv2/photo.hpp>
#include "opencv2/imgcodecs.hpp"
#include <opencv2/highgui.hpp>
#include <vector>
#include <iostream>
#include <fstream>
#include <string>

using namespace cv;
using namespace std;

void loadExposureSeq(string, vector<Mat>&, vector<float>&);

int main(int, char**argv)

{

    vector<Mat> images;
    vector<float> times;
    string strpath = "./SampleLighthouse";
    loadExposureSeq(strpath, images, times);

    for (int i = 0; i < times.size(); ++i)
    {
        cout << times[i] << " ";
    }
    cout << endl << "here" << endl;

    Mat response;
    Ptr<CalibrateDebevec> calibrate = createCalibrateDebevec();
    calibrate->process(images, response, times);
    Mat hdr;
    Ptr<MergeDebevec> merge_debevec = createMergeDebevec();
    merge_debevec->process(images, hdr, times, response);
    Mat ldr;
    Ptr<TonemapDurand> tonemap = createTonemapDurand(2.2f);
    tonemap->process(hdr, ldr);

    Mat fusion;
    Ptr<MergeMertens> merge_mertens = createMergeMertens();
    merge_mertens->process(images, fusion);

    imwrite("fusion.png", fusion * 255);
    imwrite("ldr.png", ldr * 255);
    imwrite("hdr.hdr", hdr);
    return 0;
}



void loadExposureSeq(string path, vector<Mat>& images, vector<float>& times)
{

    path = path + std::string("/");
    ifstream list_file((path + "ST.txt").c_str());
    string name;
    float val;
    while(list_file >> name >> val) {
        Mat img = imread(path + name);
        images.push_back(img);
        times.push_back(1 / val);
    }
    list_file.close();
}

在普通的顯示中無法正常顯示，就不給出了

LDR圖片


色調對映演算法感覺不好，影象的很多細節丟失了。
