ubuntu下安装opencv

叁歲伎倆 2023-05-29 05:16 53阅读 0赞

1.在官网上下载opencv：http://opencv.org/releases.html

2.解压zip包

unzip opencv-3.4.3.zip
    cd opencv-3.4.3

3.安装依赖库和cmake

sudo apt-get install cmake  
    sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg.dev libtiff4.dev libswscale-dev libjasper-dev

4.执行cmake

/* 新建编译文件夹，即build文件夹*/
    mkdir my_build_dir
    cd my_build_dir
    /* 执行cmake */
    cmake ..

5.执行make命令

sudo make  // 时间比较漫长

6.执行install命令

sudo make install

这一步执行完毕之后，Opencv的编译过程就结束了，接下来的工作就是配置一些Opencv的编译环境。

7.首先将OpenCV的库添加到路径，从而可以让系统找到

sudo gedit /etc/ld.so.conf.d/opencv.conf

执行此命令后打开的可能是一个空白的文件，只需要在文件末尾添加

/usr/local/lib

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hb2h1bGU_size_16_color_FFFFFF_t_70][]

执行如下命令使得刚才的配置路径生效：

sudo ldconfig

8.配置bash

sudo gedit /etc/bash.bashrc

在末尾追加：

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig  
    export PKG_CONFIG_PATH

保存，执行如下命令使得配置生效：

source /etc/bash.bashrc

更新：

sudo updatedb

至此，所有配置都已经完成。

9.将opencv与anaconda配置在一起

把/home/wanglin/opencv-3.4.3/my\_build\_dir/lib/cv2.so拷到anaconda/lib/python2.7/site-packages下

10.测试opencv是否安装成功

import cv2
    
    img = cv2.imread('1.jpg')
    
    cv2.imshow('image',img)
    
    cv2.waitKey(0)
    
    cv2.destroyAllWindows()

没有报错就表明安装成功。

11.opencv的卸载

(1)进入opencv的my\_build\_dir文件夹（即Build文件夹）下

sudo make uninstall

（2）删掉my\_build\_dir文件夹

cd  ..
    sudo rm -r my_build_dir

（3）删掉opencv文件夹

cd /home/wanglin
    chmod a+x /home/wanglin/opencv
    rm -r /home/wanglin/opencv(删不掉可以加sudo)

（4）删掉系统文件中opencv文件，原教程如下：

sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*

参考上述路径，我的电脑卸载：

sudo rm -r  /usr/local/include/opencv4
    sudo rm -r  /usr/include/opencv /usr/include/opencv2
    sudo rm -r /usr/local/share/opencv /usr/local/share/OpenCV
    sudo rm -r /usr/local/share/opencv4
    sudo rm -r /usr/share/opencv /usr/share/OpenCV
    sudo rm -r /usr/local/lib/libopencv*
