1.去openCV 官网下载最新的源代码。
2. 解压
unzip opencv-3.2.0.zip
3.安装(进入到解压的路径,编译)
cd opencv-3.2.0 # 你的路径 mkdir release cd release cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local .. make sudo make install
注:我在这步出现了些问题,由于缺少部分依赖,在执行下面的c代码的时候会报错。所以在编译之前,先要检查两个依赖是否安装:
libgtk2.0-dev 和 pkg-config
sudo apt-get install *** 就可以安装了。安装完成之后在执行第三步编译等。
报错信息如下:
➜ test ./DisplayImage opencv.jpeg OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows,GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian,install libgtk2.0-dev and pkg-config,then re-run cmake or configure script) in cvNamedWindow,file /home/menglei/opencv/opencv-3.2.0/modules/highgui/src/window.cpp,line 565 terminate called after throwing an instance of 'cv::Exception' what(): /home/menglei/opencv/opencv-3.2.0/modules/highgui/src/window.cpp:565: error: (-2) The function is not implemented. Rebuild the library with Windows,then re-run cmake or configure script in function cvNamedWindow
4.c++代码测试。
mkdir ~/opencv-test cd ~/opencv-test vi DisplayImage.cpp #编辑下这个文件。填写下面的内容
#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; }
5.写一个cmake编译上面的代码
touch CMakeLists.txt vi CMakeLists.txt
cmake_minimum_required(VERSION 2.8) project( DisplayImage ) find_package( OpenCV required ) add_executable( DisplayImage DisplayImage.cpp ) target_link_libraries( DisplayImage ${OpenCV_LIBS} )
编译
cd opencv-test cmake . make
运行
此时opencv-test文件夹中已经产生了可执行文件DisplayImage,随便从网上下载一张图片放在opencv-test文件夹下,此处下载了opencv.jpg,然后运行
6. 安装python-opencv 等
sudo apt-get install python-opencv sudo apt-get install python-numpy
7. 检测
python
import cv
如果成功表示安装完成
查看demo
cd opencv-3.2.0/samples/python
python demo.py
如果运行不起来,可能是缺乏什么python库,安装一下就好了。 比如sudo apt-get install python-tk
