首先安装依赖项:
1 [compiler] sudo apt-get install build-essential 2 [required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev 3 [optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev 然后在官网下载3.0安装包https://github.com/opencv/opencv/archive/3.0.0.zip解压
cd ~/opencv-3.0.0 mkdir release cd release cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local .. make sudo make install 其中在make时会报错,
解决方法:
打开/home/yhy/opencv-3.0.0/modules/cudalegacy/src/graphcuts.cpp
把此处改为:
#include "precomp.hpp" #if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) ||(CUDART_VERSION>=8000)
其中 ||(CUDART_VERSION>=8000)为后增加的内容
再次make,就不会报错
安装完后,修改环境变量:
sudo gedit /etc/ld.so.conf.d/opencv.conf
写入/usr/local/lib,保存
sudo ldconfig
sudo gedit /etc/bash.bashrc
在文末增加:
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH
保存
到此安装完成,下面开始测试安装是否成功
测试方法详见:http://www.tuicool.com/articles/nYJrYra或者另一种http://blog.csdn.net/linj_m/article/details/45048905
用第一种方法时记得在gedit CMakeLists.txt时要在内容里多加两行:
cmake_minimum_required(VERSION 2.8)
project( DisplayImage ) set(OpenCV_DIR /home/yhy/opencv-3.0.0/release) include_directories(/usr/local/include) find_package( OpenCV REQUIRED ) add_executable( DisplayImage DisplayImage.cpp ) target_link_libraries( DisplayImage ${OpenCV_LIBS} )
加粗两行为多加的,不然make会报错:
make[1]: *** [CMakeFiles/DisplayImage.dir/all] Error 2
make: *** [all] Error 2
用以上方法就可以避开这个报错
以上,就可以完成opencv的安装及检测了,祝好!
