Ubuntu14.04安装opencv3.1和opencv3.3

Posted 2020-10-13 huicanlin

视觉SLAM十四讲用到了opencv3.1，而opencv3.3增加了深度学习方面的应用，因此，编译二者用于下一步的学习和研究。

1.安装opencv3.1

安装参考链接：https://docs.opencv.org/3.1.0/d7/d9f/tutorial_linux_install.html

简要步骤：

1.1 需要的包

[compiler] sudo apt-get install build-essential

[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

1.2 下载opencv3.1

打包下载：https://github.com/opencv/opencv/archive/3.1.0.zip

也可以github源码下载：

cd ~/<my_working_directory>

git clone https://github.com/Itseez/opencv.git

git clone https://github.com/Itseez/opencv_contrib.git

1.3 编译安装

cd ~/opencv

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

(也可以cmake ..)

make -j7

sudo make install

1.4 可能碰到的问题

-- ICV: Downloading ippicv_linux_20151201.tgz...

CMake Error at 3rdparty/ippicv/downloader.cmake:73 (file):

  file DOWNLOAD HASH mismatch

 

    for file: [/home/huicanlin/Downloads/software/opencv-3.1.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/ippicv_linux_20151201.tgz]

      expected hash: [808b791a6eac9ed78d32a7666804320e]

        actual hash: [f13eaae8a6fdcdd119ee111515313781]

解决办法：

手动下载该文件，放到适当的路径，重新编译即可。

适当路径：/opencv-3.1.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/

2安装opencv3.3

安装参考链接：https://docs.opencv.org/3.3.0/d7/d9f/tutorial_linux_install.html

简要步骤：

2.1需要的包

[compiler] sudo apt-get install build-essential

[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

2.2下载opencv3.3

下载链接：https://github.com/opencv/opencv/archive/3.3.0.zip

当然也可以github上下载源码

2.3编译安装

cd ~/opencv

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

(也可以cmake ..)

make -j7

sudo make install

2.4可能碰到的问题

在cmake ..步骤中，下载ippicv_2017u2_lnx_intel64_20170418.tgz文件的时候出错.

解决办法也是手动下载，并放到合适路径，该问题的解决办法参考链接：https://github.com/opencv/opencv/issues/8641。

适当路径：~/Downloads/software/opencv-3.3.0/.cache/ippicv/

将下载的文件重命名为：87cbdeb627415d8e4bc811156289fa3a-ippicv_2017u2_lnx_intel64_20170418.tgz

重新编译安装即可。
