首先opencv和opencv_contrib下载版本要一致!!!!
我是以opencv3.4.5为例
opencv下载官网:Releases - OpenCV
opencv_contirb网址:GitHub - opencv/opencv_contrib: Repository for OpenCV's extra modules
源地址:GitHub - opencv/opencv_contrib: Repository for OpenCV's extra modules
以上即是在Ubuntu上下载好opencv和opencv_contrib
安装开始:
1 先跟新一下:
-
sudo apt-get update
-
sudo apt-get upgrade
2 安装一下依赖包
sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
3.解压下载好的包:
sudo unzip opencv-3.4.5.zip
sudo unzip opencv_contrib-3.4.5.zip
4.解压完后需要将opencv_contrib-3.4.5.zip提取到opencv-3.4.5目录下,同时在该目录下新建一个文件夹build
sudo cp -r opencv_contrib-3.4.5 opencv-3.4.5 #复制opencv_contrib到opencv目录下
cd opencv-3.4.5
sudo mkdir build #新建文件夹build
5 cd build(进入build文件夹)
cmake -D CMAKE_BUILD_TYPE=Release
-D OPENCV_GENERATE_PKGCONFIG=ON
-D CMAKE_INSTALL_PREFIX=/usr/local ..
-D OPENCV_EXTRA_MODULES_PATH=/home/*****/*****/opencv_contrib/modules ..
解释:带星号就是你opencv_contrib/modules的绝对路径 可以进入到opencv_contrib/modules中打开终端输入:pwd即可查询。
6 进行编译:make -j4
重要:如果缺少文件或者是报路径相关的错误,可以打开下面的链接看一下:

make后:sudo make install
7 配置环境变量
1)安装成功后还需要设置opencv的环境变量。打开文件:
sudo gedit /etc/ld.so.conf.d/opencv.conf
(2)将空白文档中添加以下内容:
/usr/local/lib
(3)接下来配置库:
sudo ldconfig
(4)更改环境变量:
sudo gedit /etc/bash.bashrc
(5)在文件后添加:
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
(6)保存退出,终端输入:
source /etc/bash.bashrc
至此,opencv及opencv_contrib安装配置完成了!
8 测试
进入opencv/samples/cpp/example_cmake目录下,终端打开,依次输入:
cmake .
make
./opencv_example
出现这个图像就圆满结束了,不过我是配置的c++的
