1.安装所需库等等
sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev python3.5-dev python3.5-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
2.下载opecv源码并切换分支到3.4.0
git clone https://github.com/opencv/opencv.git cd opencv/ git checkout 3.4.0
git clone https://github.com/opencv/opencv_contrib.git cd opencv_contrib/ git checkout 3.4.0
3.build
cd opencv/ mkdir build cd build/ export PY_NAME=$(python3.5 -c 'from sys import version_info as v; print("python%d.%d" % v[:2])') export PY_NUMPY_DIR=$(python3.5 -c 'import os.path, numpy.core; print(os.path.dirname(numpy.core.__file__))') cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local -DPYTHON_DEFAULT_EXECUTABLE=$(which python3.5) -DPYTHON3_EXECUTABLE=$(which python3.5) -DPYTHON3_INCLUDE_DIR=/usr/include/$PY_NAME -DPYTHON3_INCLUDE_DIR2=/usr/include/aarch64-linux-gnu/$PY_NAME -DPYTHON3_LIBRARY=/usr/lib/aarch64-linux-gnu/lib$PY_NAME.so -DPYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/$PY_NAME/dist-packages/numpy/core/include/ -DBUILD_DOCS=OFF -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..
build完成的结果
4.make&install
make -j$(nproc) sudo make install

5.想咋用就咋用
