1、安装OpenCV所需要的库
- 1
sudo apt-get install build-essential - 2
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev - 3
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
2、从官网下载OpenCV源码
http://sourceforge.net/projects/opencvlibrary/
3、编译OpenCV
- 1 使用unzip命令解压
- 2 创建编译目录，编译
cd ~/opencv-3.0.0-rc1
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install
4、测试OpenCV
- 1 创建工作目录
mkdir ~/opencv-lena
cd ~/opencv-lena
gedit DisplayImage.cpp - 2 写入测试代码
#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv ) {
if ( argc != 2 ) {
printf("usage: DisplayImage.out <Image_Path>\n");
return -1;
}
Mat image;
image = imread( argv[1], 1 );
if ( !image.data ) {
printf("No image data \n");
return -1;
}
namedWindow("Display Image", WINDOW_AUTOSIZE );
imshow("Display Image", image);
waitKey(0);
return 0;
} - 3 创建CMake编译文件
gedit CMakeLists.txt
写入如下代码
cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
find_package( OpenCV REQUIRED )
add_executable( DisplayImage DisplayImage.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBS} ) - 4 编译
首先进到文件目录，然后输入
cmake .
make - 5 运行
如果编译成功，文件目录下已经生成可执行性文件，记得图片要放在文件夹下（或指明路径），然后运行
./DisplayImage lena.jpg
