树莓派环境搭建

1.烧录系统

Operating system images – Raspberry Pi

https://shumeipai.nxez.com/2013/09/07/raspberry-pi-under-windows-system-installation-to-sd-card.h

2.远程连接（默认密码raspberry）

Preference--->Raspberry Pi Configuration--->Interface

打开SSH和VNC

3.安装OpenCV

Install OpenCV 4 on Raspberry Pi 4 and Raspbian Buster - PyImageSearch

(1)sudo raspi-config

Advanced Options

Expand filesystem

sudo reboot

(2)

# 无需科学上网
sudo apt-get update && sudo apt-get upgrade



sudo apt-get install build-essential cmake unzip pkg-config



sudo apt-get install libjpeg-dev libpng-dev libtiff-dev

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev

sudo apt-get install libxvidcore-dev libx264-dev



sudo apt-get install libgtk-3-dev



sudo apt-get install libcanberra-gtk*



sudo apt-get install libatlas-base-dev gfortran



sudo apt-get install python3-dev



------
wget https://bootstrap.pypa.io/get-pip.py

sudo python3 get-pip.py

sudo pip install virtualenv virtualenvwrapper


nano ~/.bashrc
# virtualenv and virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source /usr/local/bin/virtualenvwrapper.sh
source ~/.bashrc

mkvirtualenv cv -p python3
workon cv
pip install numpy

sudo nano /etc/dphys-swapfile
sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start

https://github.com/opencv/opencv_contrib/archive/4.5.3.zip



mv opencv-4.5.3.zip opencv.zip

mv opencv_contrib-4.5.3.zip opencv_contrib.zip

unzip opencv.zip

unzip opencv_contrib.zip

mv opencv-4.5.3 opencv

mv opencv_contrib-4.5.3 opencv_contrib

cd opencv
mkdir build
cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE 
    -D CMAKE_INSTALL_PREFIX=~/Software/OpenCV_453/opencv/build/install 
    -D OPENCV_EXTRA_MODULES_PATH=/home/pi/Software/OpenCV_453/opencv_contrib/modules 
    -D ENABLE_NEON=ON 
    -D ENABLE_VFPV3=ON 
    -D BUILD_TESTS=OFF 
    -D INSTALL_PYTHON_EXAMPLES=OFF 
    -D OPENCV_ENABLE_NONFREE=ON 
    -D CMAKE_SHARED_LINKER_FLAGS=-latomic 
    -D BUILD_EXAMPLES=OFF ..

-D OPENCV_GENERATE_PKGCONFIG=ON  // g++ -o test_code test_code.cpp -L. -lisp_bm3d `pkg-config opencv4 --cflags --libs`


make -j4
make install

注：

(1)cv环境安装pip install opencv-contrib-python

ERROR: Could not install packages due to an OSError: Missing dependencies for SOCKS support.--->unset all_proxy

(2)virtualenv奇葩问题--->创建红框文件即可（不知原因，只有一次装机中遇到，懂得小伙伴评论留言下）

4.VSCode远程树莓派

前端部署MNN+树莓派从0到1_环境配置_sinat_29634715的博客-CSDN博客

(1)安装C/C++
