前言
在Ubuntu 18.04环境下源码编译OpenCV，与Qt5、FFMpeg和X264等配合使用。
提示：以下是本篇文章正文内容，下面案例可供参考
一、开发部署环境
| 开发环境 | 软件版本 |
|---|---|
| PC系统版本 | Ubuntu 18.04LTS |
| OpenCV版本 | 3.4.10 |
| Python版本 | Python3.7 |
| numpy版本 | 1.16.3 |
二、安装步骤
1.安装编译环境所需依赖包
#安装编译所需依赖包
user@admin-machine:~$ sudo apt-get update
user@admin-machine:~$ sudo apt-get install build-essential
user@admin-machine:~$ sudo apt install software-properties-common
user@admin-machine:~$ sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
user@admin-machine:~$ sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
user@admin-machine:~$ sudo apt update
user@admin-machine:~$ sudo apt install libjasper1 libjasper-dev
user@admin-machine:~$ sudo apt-get install libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev
user@admin-machine:~$ sudo apt-get install -y libgstreamer1.0-0 \

gstreamer1.0-libav \
gstreamer1.0-doc \
gstreamer1.0-tools \
libgstreamer1.0-dev \
libgstreamer-plugins-base1.0-dev
2. 安装Python环境及依赖包
- 安装Python3.7
user@admin-machine:~$ sudo apt update #检查可更新文件
user@admin-machine:~$ sudo apt install software-properties-common #安装可添加源的工具
user@admin-machine:~$ sudo add-apt-repository ppa:deadsnakes/ppa #添加源，否则会无法找到python3.7-dev软件包
user@admin-machine:~$ sudo apt install python3.7-dev -y #安装python3.7
- 配置Python3.7环境
#查看路径python,python3.7路径
user@admin-machine:~$ which python python3.7
/usr/bin/python
/usr/bin/python3.7
user@admin-machine:~$ sudo rm /usr/bin/python
user@admin-machine:~$ sudo rm /usr/bin/python3
#创建python3.7软连接到python&Python3
user@admin-machine:~$ sudo ln -s /usr/bin/python3.7 /usr/bin/python
user@admin-machine:~$ sudo ln -s /usr/bin/python3.7 /usr/bin/python3
- 安装pip包和numpy
user@admin-machine:~$ sudo apt-get install python3-pip -y
user@admin-machine:~$ sudo python3 -m pip install --upgrade --force-reinstall pip
user@admin-machine:~$ pip3 -V
pip 21.0.1 from /usr/local/lib/python3.7/dist-packages/pip (python 3.7)
user@admin-machine:~$ pip3 install numpy==1.16.3 -i https://pypi.tuna.tsinghua.edu.cn/simple
user@admin-machine:~$ pip3 show numpy
Name: numpy
Version: 1.16.3
Summary: NumPy is the fundamental package for array computing with Python.

- 添加动态库加载路径
user@admin-machine:~$ sudo vim /etc/ld.so.conf.d/opencv.conf
/home/user/opencv/opencv-3.4.10/release/install/lib
vim中输入:wq指令保存并退出，随后运行sudo ldconfig激活生效。
- 运行
sudo vim /etc/bash.bashrc在最后一行添加如下
PKG_CONFIG_PATH=/home/user/opencv/opencv-3.4.10/release/install/lib/pkgconfig:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH
vim中输入:wq指令保存并退出，随后运行source ~/.bashrc激活生效。
- 重启PC
user@admin-machine:~$ sudo reboot
- 验证OpenCV动态链接库是否生效，若出现以下路径，则表明动态链接库生效
user@admin-machine:~$ pkg-config --libs --cflags opencv
-I/home/user/opencv/opencv-3.4.10/release/install/include/opencv -I/home/user/opencv/opencv-3.4.10/release/install/include -L/home/user/opencv/opencv-3.4.10/release/install/lib -lopencv_dnn -lopencv_highgui -lopencv_ml -lopencv_objdetect -lopencv_shape -lopencv_stitching -lopencv_superres -lopencv_videostab -lopencv_calib3d -lopencv_videoio -lopencv_imgcodecs -lopencv_features2d -lopencv_video -lopencv_photo -lopencv_imgproc -lopencv_flann -lopencv_core
4. 测试opencv是否编译成功
打开/home/user/opencv/opencv-3.4.10/samples/cpp/example_cmake目录，修改CMakeLists.txt，指定OpenCVConfig.cmake opencv-config.cmake的安装路径，否则cmake会报错。
执行：
user@admin-machine:~$ sudo vim CMakeLists.txt
# cmake needs this line
cmake_minimum_required(VERSION 2.8)
# Define project name
project(opencv_example_project)
# Find OpenCV, you may need to set OpenCV_DIR variable
# to the absolute path to the directory containing OpenCVConfig.cmake file
# via the command line or GUI
#新增以下行，指定OpenCV__DIR的路径
set(OpenCV_DIR /home/user/opencv/opencv-3.4.10/release/install/share/OpenCV)
find_package(OpenCV REQUIRED)
# If the package has been found, several variables will
# be set, you can find the full list with descriptions
# in the OpenCVConfig.cmake file.
# Print some message showing some of them
message(STATUS "OpenCV library status:")
message(STATUS " version: ${OpenCV_VERSION}")
message(STATUS " libraries: ${OpenCV_LIBS}")
message(STATUS " include path: ${OpenCV_INCLUDE_DIRS}")
if(CMAKE_VERSION VERSION_LESS "2.8.11")
# Add OpenCV headers location to your include paths
include_directories(${OpenCV_INCLUDE_DIRS})
endif()
# Declare the executable target built from your sources
add_executable(opencv_example example.cpp)
# Link your application with OpenCV libraries
target_link_libraries(opencv_example PRIVATE ${OpenCV_LIBS})
user@admin-machine:~$ cmake .
user@admin-machine:~$ make
user@admin-machine:~$ ./opencv_example
执行完成后会弹出一个窗口，并实时显示电脑USB摄像头拍到的画面。
user@admin-machine:~$ python3
>>> import cv2
>>> cv2.__version__
'3.4.10'
5. 附上cmake配置文件
（以下命令是在AIO-3399ProC开发板上执行的，执行前先编译nasm，x.264及ffmpeg，具体步骤参考此文：《解决(ARM64-ARMV8)嵌入式Linux系统下X264编码提示：libx264 ：use cpu capability none！》）

总结
OpenCV源码编译过程繁琐，之前用Cmake-gui工具编译一直出错，还是在命令行中手动配置后编译方正常通过。
部分参考文章：

- How to build opencv-python如何本地编译OpenCV的Python版本
- Ubuntu 20.04 从源码编译并配置OpenCV 4.4.0 以及python 3.8支持
