*概要 [#f5c9ae90]
-[[Raspberry Pi 3]]がリリースされたのでOpenCV 3.1.0 をインストールしてみた
*前提準備 [#c7605077]
-[[Raspberry Pi 3]]を参照
*今回のターゲット [#y3001088]
-Raspberry Pi 3
-Raspbian Jessie March 2016
-Arm Cortex A53 1.2GHz Quad-core
*OpenCV の取得 [#fc32b37b]
-まずはgitでcloneする

-そして、3.1.0をチェックアウトする
pi@raspberrypi:~ $ cd opencv/
pi@raspberrypi:~/opencv $ time git checkout -b Branch_3_1_0 3.1.0

*OpenCV3.1.0のビルド [#ic63bf0e]
-NEONの有効性も検証したいので -DENABLE_NEON:BOOL=ON する
-ついでにexamplesもビルドする
-cmakeのfull logは[[こちら>https://gist.github.com/tomoaki0705/cb8251f1005e686a808b]]
-make allのfull logは[[こちら>https://gist.github.com/tomoaki0705/e9445a6342ac0b2b22e6]]
-make installのfull logは[[こちら>https://gist.github.com/tomoaki0705/807078d3fca95c03b142]]
**cmake [#edc37784]
-[[ODROID-X2でOpenCV 3.1.0をビルド]]同様、out of source buildする
pi@raspberrypi:~/opencv $ mkdir build
pi@raspberrypi:~/opencv $ cd build/
pi@raspberrypi:~/opencv/build $ time cmake -DBUILD_EXAMPLES:BOOL=ON -DENABLE_NEON:BOOL=ON ../

(中略)
real 52m59.333s

**make install [#zac1d613]
-installにはsudoをつける
pi@raspberrypi:~/opencv/build $ time sudo make install
