OpenCV Install

Standartinis įdiegtas OpenCV nepalaiko gstreamer, manipuliavimo su kameromis ir H.264/H.265 hardware codec'ų. Todėl jį reikia įdiegti švariai iš source.

apt-get install python3.7 python3.7-dev
update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 1
python3 --version # Turi rodyti 3.7.5 >=
cd
git clone https://github.com/jkjung-avt/jetson_nano.git
cd jetson_nano
./install_opencv-3.4.6.sh # Šis scriptas taip pat išvalo senus užsilikusius OpenCV diegimus
