開啟Terminal後, 輸入如下:

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

便開始下載opencv3.4.3.套件,

接著解壓縮此套件, 輸入:

unzip 3.4.3.zip

安裝opencv前先安裝其他套件(共15個),

ubtuntu version: 16.04

sudo apt-get install \
libglew-dev \
libtiff5-dev \
zlib1g-dev \
libjpeg-dev \
libpng12-dev \
libjasper-dev \
libavcodec-dev \
libavformat-dev \
libavutil-dev \
libpostproc-dev \
libswscale-dev \
libeigen3-dev \
libtbb-dev \
libgtk2.0-dev \
pkg-config 

ubtuntu version: 18.04

sudo apt-get install \
libglew-dev \
libtiff5-dev \
zlib1g-dev \
libjpeg-dev \
libpng-dev \
libjasper-dev \
libavcodec-dev \
libavformat-dev \
libavutil-dev \
libpostproc-dev \
libswscale-dev \
libeigen3-dev \
libtbb-dev \
libgtk2.0-dev \
pkg-config

補充: libjasper-dev在ubuntu 18.04找不到套件 

然而TX2本身未安裝cmake套件,

因此需要在額外安裝cmake,

sudo apt-get update

sudo apt-get install cmake

如果先前已經安裝過舊版本的opencv,

先做刪除動作(如未安裝過可省略),

sudo apt-get purge libopencv*

指定到已解壓縮的opencv目錄:

cd opencv-3.4.3

新建build資料夾至opencv目錄內,

mkdir build

指定到build目錄

cd build

接著使用cmake建置opencv相關套件

cmake \
 -DCMAKE_BUILD_TYPE=Release \
 -DCMAKE_INSTALL_PREFIX=/usr/local \
 -DBUILD_PNG=OFF \
 -DBUILD_TIFF=OFF \
 -DBUILD_TBB=OFF \
 -DBUILD_JPEG=OFF \
 -DBUILD_JASPER=OFF \
 -DBUILD_ZLIB=OFF \
 -DBUILD_EXAMPLES=ON \
 -DBUILD_opencv_java=OFF \
 -DBUILD_opencv_python2=OFF \
 -DBUILD_opencv_python3=ON \
 -DENABLE_PRECOMPILED_HEADERS=OFF \
 -DWITH_OPENCL=OFF \
 -DWITH_OPENMP=OFF \
 -DWITH_FFMPEG=ON \
 -DWITH_GSTREAMER=OFF \
 -DWITH_GSTREAMER_0_10=OFF \
 -DWITH_CUDA=ON \
 -DWITH_GTK=ON \
 -DWITH_VTK=OFF \
 -DWITH_TBB=OFF \
 -DWITH_1394=OFF \
 -DWITH_OPENEXR=OFF \
 -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda \
 -DCUDA_ARCH_BIN=6.2 \
 -DCUDA_ARCH_PTX="" \
 -DINSTALL_C_EXAMPLES=OFF \
 -DINSTALL_TESTS=OFF \
 .. 
 

接著設定TX2 CUP核心模式來建置opecv

利用4核模式輸入:

sudo make -j4

利用6核模式輸入:

sudo make -j6

開始安裝opencv

sudo make install

驗證安裝結果:

python3

import cv2

如果輸入完沒出現錯誤訊息表示成功
