Ubuntu结合CV 0.0

安装Ubuntu版opencv

在 https://github.com/opencv/opencv 下载源码，在源码根目录下打开终端

mkdir build
cd build
cmake ..
make -j 
sudo make install

 

配置环境

sudo gedit /etc/ld.so.conf.d/opencv.conf    ，接着在文件夹里添加 opencv 库的安装路径：/usr/local/lib

sudo ldconfig        使得刚才配置的路径生效，更新系统共享链接库

sudo gedit /etc/bash.bashrc            

在文件末尾加入：
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig  及
export PKG_CONFIG_PATH

source /etc/bash.bashrc                  配置生效

sudo apt-get install mlocate          下载 mlocate依赖（否则后一步找不到命令）

sudo updatedb                               更新设置

 

输入指令查看是否已安装成功

pkg-config --modversion opencv

应返回版本号

 

 

方法2：（只安装python版本）

pip install opencv-python --user

 

 

 

 

 

 

 

 

 

 

方法3：（失败）

apt-cache search opencv
