概要

  • OpenCV 3.2がリリースされたのでRaspberry Pi 3上でビルドしてみた

前提準備

今回のターゲット

  • Raspberry Pi 3
  • Raspbian Jessie March 2016
  • Arm Cortex A53 1.2GHz Quad-core
  • OpenCV 3.2.0
  • cmake 3.6.2
  • gcc 4.9.2

OpenCV の取得

  • gitでcloneして
  • 3.2.0をチェックアウトする
  • パスは適宜合わせて
    pi@raspberrypi:~ $ cd opencv-fork/
    pi@raspberrypi:~/opencv-fork $ time git checkout -b Branch_3_2_0 3.2.0
    Switched to a new branch 'Branch_3_2_0'
  • 詳細は割愛

OpenCV3.2.0のビルド

  • NEONの有効性も検証したいので -DENABLE_NEON:BOOL=ON する
  • cmakeのfull logはこちら
  • make allのfull logはこちら

cmake

  • ODROID-X2でOpenCV 3.1.0をビルド同様、out of source buildする
    pi@raspberrypi:~/opencv-fork $ mkdir build
    pi@raspberrypi:~/opencv-fork $ cd build/
    pi@raspberrypi:~/opencv-fork/build $ time cmake -DENABLE_NEON:BOOL=ON ../
    (中略)
    
    real	1m23.813s
    user	1m0.690s
    sys	0m7.080s
  • 約1分24秒で終了

make all

  • Armの4coreをフルに使う
    pi@raspberrypi:~/opencv-fork/build $ time make -j4 all
    (中略)
    
    real	56m16.801s
    user	179m10.090s
    sys	3m47.090s
  • 約56分で終了

make install

  • installにはsudoをつける
    pi@raspberrypi:~/opencv-fork/build $ time sudo make install
    (割愛)
