本文主要是介绍ubuntu安装opencv4.7.0，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

step1:
1.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential

sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg-dev libswscale-dev libtiff5-dev
sudo apt-get install libcanberra-gtk-module
sudo apt-get install pkg-config

3.下载opencv源码：

https://opencv.org/releases/

4.解压后创建新的文件夹build，然后进入build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. 
sudo make -j8
sudo make install

/usr/local 可以替换为自己的路径

step2:进行文件配置

打开ld.so.conf文件(文件可能为空白，不用管他)，并在文件末尾加上一行内容【/usr/local/lib】

sudo gedit /etc/ld.so.conf

加载配置，使刚才添加的内容生效。

sudo ldconfig

打开bash.bashrc文件，在文件末尾添加以下两行内容：

sudo gedit /etc/bash.bashrc

添加的内容：

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

运行bash.bashrc：

source /etc/bash.bashrc

更新系统的配置环境

sudo updatedb

创建并配置opencv.pc文件

执行以下命令创建并打开opencv.pc文件：

cd /usr/local/lib/pkgconfig
touch opencv.pc
sudo gedit opencv.pc

打开文件后，添加以下内容并保存关闭文件：

prefix=/usr/local
exec_prefix=${prefix}
includedir=/usr/local/include
libdir=/usr/local/libName: OpenCV
Description: Open Source Computer Vision Library
Version: 4.7.0
