 Ubuntu  安装OpenCV3.0.0

为了看看opencv3.0的HDR效果，尝试安装opencv3.0到ubuntu12.04上面，安装了好几次终于成功了。

卸载方法 OpenCv卸载

http://stackoverflow.com/questions/13134151/how-to-uninstall-opencv-in-ubuntu

You can also uninstall by going to the "build" folder directory of opencv from terminal, and execute the following
make uninstall
cd ..
sudo rm -r build

sudo rm -r /usr/local/include/opencv2
/usr/local/include/opencv
/usr/include/opencv
/usr/include/opencv2
/usr/local/share/opencv
/usr/local/share/OpenCV
/usr/share/opencv
/usr/share/OpenCV
/usr/local/bin/opencv*
/usr/local/lib/libopencv*

OpenCV安装
1 系统更新
利用ubuntu自带的更新管理器或者
sudo apt-get update
sudo apt-get upgrade

2 安装必要的组件
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 下载opencv3.0

http://opencv.org/downloads.html

解压到某个文件下，这里选择
/home/yourname/opencv3.0

4  编译opecv3.0
进入解压后的opencv3.0目录

mkdir build

进入build目录

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 安装opencv3.0

在build目录
make
sudo make install

6 配置opencv.conf file ，加入环境变量
sudo gedit /etc/ld.so.conf.d/opencv.conf

在opencv.conf里面加入命令
/usr/local/lib

更新库目录
sudo ldconfig

打开文件bash.bashrc
sudo gedit /etc/bash.bashrc
加入下面两行
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH



7 测试你的opencv3.0是否安装成功

编译不通过请注销或者重启电脑试试

测试代码：opencvtest.cpp

[cpp] view plaincopy

1. #include <opencv2/core/core.hpp>  
2. #include <opencv2/highgui/highgui.hpp>  
3. using namespace cv;  
4.   
5. int main()  
6. {  
7.     Mat src = imread("test.jpg",1);  
8.     imshow("src",src);  
9.     waitKey(0);  
10.     return 0;  
11. }  

注意：linux下面的目录形式为/.../....

所以“#include <opencv2\core\core.hpp>” 会找不到头文件

编译方式：
1 命令行
g++  opencvtest.cpp -o opencvtest  `pkg-config  --cflags --libs opencv`

2 借助cmake，写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} )

之后 执行

cmake .
Make
 运行
./ opencvtest


8 opnecv3.0的HDR效果测试

[cpp] view plaincopy

1. #include <opencv2/photo.hpp>  
2. #include "opencv2/imgcodecs.hpp"  
3. #include <opencv2/highgui.hpp>  
4. #include <vector>  
5. #include <iostream>  
6. #include <fstream>  
7. #include <string>  
8.   
9. using namespace cv;  
10. using namespace std;  
11.   
12. void loadExposureSeq(string, vector<Mat>&, vector<float>&);  
13.   
14. int main(int, char**argv)  
15.   
16. {  
17.   
18.     vector<Mat> images;  
19.     vector<float> times;  
20.     string strpath = "./SampleLighthouse";  
21.     loadExposureSeq(strpath, images, times);  
22.   
23.     for (int i = 0; i < times.size(); ++i)  
24.     {  
25.         cout << times[i] << " ";  
26.     }  
27.     cout << endl << "here" << endl;  
28.   
29.     Mat response;  
30.     Ptr<CalibrateDebevec> calibrate = createCalibrateDebevec();  
31.     calibrate->process(images, response, times);  
32.     Mat hdr;  
33.     Ptr<MergeDebevec> merge_debevec = createMergeDebevec();  
34.     merge_debevec->process(images, hdr, times, response);  
35.     Mat ldr;  
36.     Ptr<TonemapDurand> tonemap = createTonemapDurand(2.2f);  
37.     tonemap->process(hdr, ldr);  
38.   
39.     Mat fusion;  
40.     Ptr<MergeMertens> merge_mertens = createMergeMertens();  
41.     merge_mertens->process(images, fusion);  
42.   
43.     imwrite("fusion.png", fusion * 255);  
44.     imwrite("ldr.png", ldr * 255);  
45.     imwrite("hdr.hdr", hdr);  
46.     return 0;  
47. }  
48.   
49.   
50.   
51. void loadExposureSeq(string path, vector<Mat>& images, vector<float>& times)  
52. {  
53.   
54.     path = path + std::string("/");  
55.     ifstream list_file((path + "ST.txt").c_str());  
56.     string name;  
57.     float val;  
58.     while(list_file >> name >> val) {  
59.         Mat img = imread(path + name);  
60.         images.push_back(img);  
61.         times.push_back(1 / val);  
62.     }  
63.     list_file.close();  
64. }  

曝光时间 ST.txt
s1.jpg 40.0
s2.jpg 10.0
s3.jpg 2.0

HDR图片

在普通的显示中无法正常显示，就不给出了

LDR图片


色调映射算法感觉不好，图像的很多细节丢失了。
