安裝Ubuntu自己裝步驟略。

1.安裝Qt

1.1 安裝qt-opensource-linux-x64-5.7.1.run

· 1、將下載的安裝文件qt-opensource-linux-x64-5.7.1.run直接右鍵copy to home/用戶目錄，如/home/user，我的是home/hzl下

· 2 、如果qt-opensource-linux-x64-5.7.1.run的屬性中擁有者沒有運行許可權，則可用chmod命令添加執行許可權:

chmod u+x qt-opensource-linux-x64-5.7.1.run

· 3 、在終端執行：

./qt-opensource-linux-x64-5.7.1.run

4、跳出安裝界面，一直點擊下一步，直到安裝完成即可

啟動QT後,將其鎖定到邊框

2.安裝Opencv.

參考：

http://lib.csdn.net/article/opencv/25737

改動版：我的是opencv-3.0.0

1、安裝依賴的庫

sudo apt-get install build-essential # 必須的，gcc編譯環境sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev # 必須的,包括cmake等工具sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev # 可選的，看個人需要，總共5M左右我都要來怕出幺蛾子

2、下載源碼

· 在官網下載：http://opencv.org/downloads.html

· 或著用git clone：

cd ~/opencv300 # opencv310是自己提前建的，源碼將放在這裡git clone https://github.com/Itseez/opencv.gitgit clone https://github.com/Itseez/opencv_contrib.git

我的提前下好了，所以沒用上頭的指令直接走下一步：

3、使用cmake安裝

· 從優盤中copy到了home/user我的是home/hzl下，再解壓源碼包右鍵的Extract Here，得到opencv-3.0.0文件夾 （用git的話，即是opencv300）通過驗證cmake版本知道自己裝沒裝cmake :cmake --version

· 然後通過下頭指令建立編譯目標文件夾即build文件夾

cd opencv-3.0.0mkdir build

· 使用cmake或著用cmake-gui生成Makefile

(1) cmake方式（我用的方式）

cd build/（主要是為了把路徑指在opencv-3.0.0/build下，故靈活些前邊已經指到opencv的文件夾了，只寫build就行）cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. # 生成後的Makefile在build文件夾中，而需要的CMakeLists.txt在 ".."中，即上一級文件夾中（opencv-3.0.0）

在Configure過程中，若出現

– ICV: Downloading ippicv_linux_20141027.tgz… 。。。。 停住了！！！ 則下載 ippicv_linux_20141027.tgz，替換掉

opencv-3.0.0/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b 下的同名文件即可，注意替換後，重新編譯，或著一開始就放進去

(2) cmake-gui方式 （我用的上邊那種這種就沒用啦。）

cmake-gui即cmake和圖形界面版程序： 先安裝cmake-gui

sudo apt-get install cmake-qt-gui

然後打開cmake-gui：

「/opencv-3.1.0」 和 「/opencv-3.1.0/build」換成自己的，然後先點 Configure 然後點 Generate。

4、安裝OpenCv

在opencv3.0.0/build下，終端運行：

make -j7 # 7個線程編譯（這步運行完要好久）sudo make install # 安裝

Qt 5.7.1配置調用opencv3.0.0

· 1、打開Qt，點擊「New Project」

· 2、依次選擇：application——Qt Console Application，點擊右下角Choose

· 3、可修改「名稱」創建新的路徑，也可為默認值。

· 4、打開左上角的pro文件，在其最下面添加如下內容：

注意：以下內容為cmake時設置的路徑CMAKE_INSTALL_PREFIX=/usr/local/opencv320下的路徑及相應的文件，一般默認的路徑是/usr/local/，總之，在cmake時設置的路徑下找下列內容即可。

自己找一下自己文件的對應位置修改下邊的，還有lib文件可以通過Terminal先指到指定空間，再用ls指令列出lib下的文件名複製修改下列程序中的庫名。下邊是按我的路徑和庫寫的。

再在main.cpp中寫下列程序測試：（要提前將圖片放入這個工程的文件夾中，且在imread後要寫完整的圖片路徑，不然會報錯：

OpenCV Error: Assertion

failed (size.width>0 && size.height>0) in imshow, file

/home/hzl/opencv-3.0.0/modules/highgui/src/window.cpp, line 271

terminate called after

throwing an instance of cv::Exception

what(): /home/hzl/opencv-3.0.0/modules/highgui/src/window.cpp:271: error: (-215)

size.width>0 && size.height>0 in function imshow）

所以下邊的程序按自己的文件改圖片路徑

#include <QCoreApplication>#include <opencv2/highgui.hpp>#include <opencv2/core.hpp>#include <opencv2/imgproc.hpp>#include <iostream>using namespace cv;using namespace std;int main(int argc, char *argv[]){ Mat image; image = imread("/home/hzl/untitled1/timg.jpeg"); // Read the file if(!image.data) { cout << "nenhuma imagem!"; } else { cout << "imagem carregada!"; } cv::namedWindow("Teste imagem"); cv::imshow("Teste imagem", image); cv::waitKey(0); return 0;}

效果圖如下：
