ubuntu安装与卸载opencv与opencv_contrib

今天药忘吃喽~ 2021-11-09 15:20 473阅读 0赞

最近要用到CSRT跟踪器，要求opencv\_contrib版本3.4.2及其以上，记录下安装过程（之前opencv和opencv\_contrib版本都是3.4.0）

## 零、安装依赖项 ##

注：只是更新版本的请忽略

sudo apt-get install build-essential
    sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
    sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
    sudo apt-get install cmake-gui

## 一、下载对应版本opencv和opencv\_contrib ##

opencv: https://opencv.org/  
opencv\_contrib: https://github.com/opencv/opencv\_contrib/releases  
opencv在右上角release中找到并下载对应版本source zip，opencv\_contrib也下载压缩文件，且保证与opencv版本相同

## 二、卸载老版本opencv ##

找到之前安装opencv的build目录

cd OpenCV_ROOT/build
    sudo make uninstall
    cd  ..
    sudo rm -rf build

删除残留系统中的opencv文件

sudo rm -rf /usr/local/include/opencv*
    sudo rm -rf /usr/include/opencv*
    sudo rm -rf /usr/local/share/opencv 
    sudo rm -rf /usr/local/share/OpenCV 
    sudo rm -rf /usr/share/opencv 
    sudo rm -rf /usr/share/OpenCV
    sudo rm -rf /usr/local/bin/opencv* 
    sudo rm -rf /usr/local/lib/libopencv*
    sudo rm -rf /usr/share/doc/libopencv*
    sudo rm -rf /usr/share/doc/opencv*
    sudo rm -rf /usr/share/lintian/overrides/libopencv*
    sudo rm -rf /usr/lib/x86_64-linux-gnu/libopencv*
    sudo rm -rf /var/lib/dpkg/info/libopencv*
    sudo rm -rf /usr/lib/jni/libopencv*
    sudo rm -rf /usr/bin/opencv*
    sudo rm -rf /usr/share/lintian/overrides/libopencv*
    sudo rm -rf /usr/share/java/opencv*

## 三、安装前配置 ##

解压刚下载的opencv和opencv\_contrib，并将opencv\_contrib加压至opencv文件夹中，并改名为contrib（其实随便，不改名也行，这样显得规整一些）

#进入opencv文件夹
    cd OpenCV_NEW_ROOT
    mkdir build
    cmake-gui

where is the source code选择opencv文件夹，where to build the binaries选择刚建立的build文件

点击Configure，后点finish

等待一段时间显示：Configuring done后

修改两处内容：

在CMAKE_BUILD_TYPE 值处输入RELEASE
    
    在OPENCV_EXTRA_MODULES_PATH处选择contrib里的module文件夹路径（记得一定是contrib里的module的路径，不是contrib的）

之后点击Generate

## 四、安装 ##

#在build文件夹中
    make
    sudo make install

安装完毕

## 五、可能遇见的错误 ##

/home/ubuntu/Tools/opencv-3.4.13/modules/stitching/src/matchers.cpp:52:35: fatal error: opencv2/xfeatures2d.hpp: No such file or directory
    类似这种错误就是在发生错误的文件中，把未找到文件的地址换成绝对地址
