踩坑无数含泪写下教程系列（一）树莓派opencv环境的搭建

Step 1:make sure your OS is current.

sudo apt-get update

sudo apt-get upgrade

Step 2: install dependencies

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

sudo apt-get install libjpeg-dev libtiff5-dev libjasper-dev libpng12-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 libgtk2.0-dev libgtk-3-dev

sudo apt-get install libatlas-base-dev gfortran

Step 3: install Python 3

sudo apt-get install python3-dev

Step 4: install pip3

sudo apt-get install python3-pip

Step 5: get the latest (3.4.3) OpenCV source code

wget -O opencv.zip https://github.com/opencv/opencv/archive/3.4.3.zip

wget -O opencv_contrib.zip
https://github.com/opencv/opencv_contrib/archive/3.4.3.zip

unzip opencv.zip

unzip opencv_contrib.zip

Step 6: install Numpy, Scipy

sudo pip3 install numpy scipy

Step 7: compile OpenCV

cd ~/opencv-3.4.3/

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE \

-D CMAKE_INSTALL_PREFIX=/usr/local \

-D INSTALL_PYTHON_EXAMPLES=ON \

-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.4.3/modules \

-D BUILD_EXAMPLES=ON …

(Make sure cmake finishes without errors)

Step 8: build OpenCV.

sudo make

Once OpenCV builds successfully, continue the installation:

sudo make install

sudo ldconfig

sudo apt-get update

… then reboot the system - and you should be good to go!

sudo reboot

Step 9: test your OpenCV installation
