$ sudo apt-get update && sudo apt-get upgrade
현재 설치된 버전 확인
$ pkg-config opencv --modversion 3.3.1 $ python -c "import cv2; print (cv2.__version__)" 3.3.1 $ python3 -c "import cv2; print (cv2.__version__)" 3.3.1
OpenCV 4.1 설치
Jetson Nano에 OpenCV 4.0 버전을 설치하는 스크립트를 다운받아서 OpenCV 4.1으로 변경해서 설치 스크립트를 만들고 실행만 하면 간단하게 OpenCV 4.1이 설치가 됩니다.
$ wget https://raw.githubusercontent.com/AastaNV/JEP/master/script/install_opencv4.0.0_Nano.sh $ cp install_opencv4.0.0_Nano.sh install_opencv4.1.0_Nano.sh $ sed -i 's/4.0.0/4.1.0/g' install_opencv4.1.0_Nano.sh $ mkdir opencv410 $ chmod 755 install_opencv4.1.0_Nano.sh $ sudo ./install_opencv4.1.0_Nano.sh opencv410
