ubuntu16.04安装opencv3.1.0(整理)

sudo apt-get install build-essential
# 必须的，gcc编译环境

sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
# 必须的,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
# 可选的，看个人需要，总共5M左右

cd ~/opencv310
# opencv310为自己建的，源码将放在这里
git clone https://github.com/Itseez/opencv.git git clone https://github.com/Itseez/opencv_contrib.git[/code] 
3、cmake

解压opencv-3.1.0.zip

cd opencv-3.1.0
mkdir build


cmake时ippicv_linux_20151201.tgz总是不能成功下载，故cmake之前将

./downloads/linux-808b791a6eac9ed78d32a7666804320e      文件拷贝至

./opencv-3.1.0/3rdparty/ippicv/    路径下

(先执行一次cmake 命令生成文件路径，在将ippicv_linux_20151201.tgz复制进去)

ippicv_linux_20151201.tgz下载链接: https://pan.baidu.com/s/1hWwR8VtHRwKNRmOilskmwA 密码: kvdz

cd opencv-3.1.0/build
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
# 生成后的Makefile在build文件夹中，而需要的CMakeLists.txt在 ".."中，即上一级文件夹中（opencv-3.1.0）




如果要安装包含opencv_contrib模块的，则执行以下语句：

cd opencv-3.1.0/build
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/home/he/opencv-3.1.0/opencv_contrib-master/modules/ ..
# “/home/he/opencv-3.1.0/opencv_contrib-master/modules/”是opencv_contrib-master解压后的路径


报错了



4、安装opencv

在opencv3.1.0/build下

# 4个线程编译,查看cpu核数量
# grep "model name" /proc/cpuinfo | wc -l
make -j4

# 安装
sudo make install


测试安装是否成功，查看这篇：

ubuntu opencv3.1 编译demo报错 http://blog.csdn.net/u011440558/article/details/78213796

ubuntu 14.04 64位安装Opencv3.1.0+包含opencv_contrib模块

http://blog.csdn.net/jay463261929/article/details/53197228

报错:fatal error hdf5.h no such file or directory



解决办法：

在opencv-3.1.0/modules/python/common.cmake首行添加如下代码：

find_package(HDF5)
include_directories(${HDF5_INCLUDE_DIRS})


OK…

参考：https://github.com/opencv/opencv/issues/6016

opencv添加软连接到virtualenv环境

参考http://blog.csdn.net/isuker/article/details/52459992

安装pip和virtualenv：

sudo apt-get install python-pip python-dev python-virtualenv


创建 Virtualenv 虚拟环境：

virtualenv --no-site-packages seg-env


将 cv.py  cv2.so文件连接到虚拟环境：



ln -s /usr/local/lib/python2.7/dist-packages/cv2.so /home/ly/seg-env/lib/python2.7/site-packages




OK…
