[Jetson Nano] OpenCV 설치

1. Jetson Nano에 이미 설치된 openCV가 있는지 확인

pkg-config --modversion opencv

 

 

2. OpenCV 관련 삭제

sudo apt-get purge libopencv* python-opencv #설치된 opencv 관련 라이브러리 삭제
sudo apt-get autoremove #필요없는 라이브러리 삭제
sudo find /usr/local/ -name "*opencv*" -exec rm -i {} \; #opencv 관련 삭제

 

 

3. 업데이트

sudo apt-get update
sudo apt-get upgrade

5. OpenCV 설치 관련 파일 다운로드 및 밑작업

#다운로드
cd ~ #홈 디렉터리로 이동
wget -O opencv.zip https://github.com/opencv/opencv/archive/4.5.0.zip
wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/4.5.0.zip

#압축해제
unzip opencv.zip
unzip opencv_contrib.zip

#폴더명 변경
mv opencv-4.5.0 opencv

7. OpenCV 빌드

make -j4
sudo rm -rf /usr/include/opencv4/opencv2
sudo make install

 

 

8. 빌드 확인

cat /etc/ld.so.conf.d/*  #'/usr/local/lib' 출력되는지 확인


#'/usr/local/lib'출력되지 않는 경우
sudo sh -c 'echo '/usr/local/lib' > /etc/ld.so.conf.d/opencv.conf'
sudo idconfig

 

 

9. OpenCV 설치 확인

python3
 >>>import cv2
 >>>cv2.__version__
 '4.5.0'
 >>>exit()
