OpenCV) Ubuntu 20.04에 OpenCV 4.4.0 설치
작성일자 - 23.05.22
https://webnautes.tistory.com/1433
아래의 process는 위의 티스토리블로그에서 진행해보고 필자가 자주 필요하여 가져와 요약하였다.
사실 jupyter notebook과 같은 환경에서는
install opencv-python
install opencv-contrib-python 만 해줘도 된다..
기존 OpenCV 확인
pkg-config --modversion opencv
을 입력했을 때, opencv의 버전이 출력된다면, opencv가 기설치 되어있는 것이고, 아래의 사진과 같이 뜨면 opencv가 설치되어있지 않은 것이다.
opencv 삭제
sudo apt-get purge libopencv* python-opencv
sudo apt-get autoremove
libopencv*을 입력하여 모든 버전의 opencv 라이브러리를 purge를 통해 삭제한다.
설치준비
패키지 업그레이드
sudo apt update
sudo apt upgrade
를 통해 기본적인 패키지를 업그레이드한다.
sudo apt-get install build-essential cmake
sudo apt-get install pkg-config
sudo apt-get install libjpeg-dev libtiff5-dev libpng-dev
sudo apt-get install ffmpeg libavcodec-dev libavformat-dev libswscale-dev libxvidcore-dev libx264-dev libxine2-dev
sudo apt-get install libv4l-dev v4l-utils
sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
sudo apt-get install libgtk-3-dev
sudo apt-get install mesa-utils libgl1-mesa-dri libgtkgl2.0-dev libgtkglext1-dev
sudo apt-get install libatlas-base-dev gfortran libeigen3-dev
sudo apt-get install python3-dev python3-numpy
이 많은 패키지들을 한번에 다운받기 위해 아래처럼 줄여보았다.
sudo apt-get install build-essential cmake pkg-config libjpeg-dev libtiff5-dev libpng-dev ffmpeg libavcodec-dev libavformat-dev libswscale-dev libxvidcore-dev libx264-dev libxine2-dev libv4l-dev v4l-utils libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgtk-3-dev mesa-utils libgl1-mesa-dri libgtkgl2.0-dev libgtkglext1-dev libatlas-base-dev gfortran libeigen3-dev python3-dev python3-numpy -y
쭉 긁어다가 입력하면 모두 한방에 깔린다. 이또한 필자가 자주 필요해서 줄여보았다.
OpenCV 설치
디렉토리를 새로 만든 후 아래의 process를 진행한다.
wget -O opencv.zip https://github.com/opencv/opencv/archive/4.4.0.zip
wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/4.4.0.zip
unzip opencv.zip
unzip opencv_contrib.zip
그냥 opencv와 contrib_opencv 둘다 설치해준다.
필자는 arucomarker등 확장 opencv가 필요하기 때문이다.
이제, opencv-4.4.0에 build디렉토리를 만들어 cmake한다.

부분이 출력되었다면, 정상적으로 된 것이다.
이 때, python3 라이브러리 항목이 보이지 않는경우는, cmake할 때, python3관련 경로들을 직접 설정해주어야 한다.
python3 이후 부터의 경로가 python3 와 관련된 라이브러리다.
time make -j$(nproc)
이제, make명령을 통해 컴파일을 시작한다. 앞에 time을 붙여 컴파일 후 완료 시간이 뜨도록 한다.
됐다.
sudo make install
이제, 결과물을 설치한다.
