*概要 [#s736d806]
-OpenCV 3.1.0 がリリースされたので[[Jetson TK1]]上にインストールしてみた

*前提準備 [#hd395297]
-[[Jetson TK1でOpenCV3.0.0#OpenCVのビルドに必要なもの>Jetson TK1でOpenCV3.0.0#jb66d291]]を参照

*今回のターゲット [#lb6c8c2b]
-Jetson TK1
-L4T (Ubuntu 14.04をベースにしたもの)
-ARM A15 w/ neon
-Arm A15 w/ neon
-Tegra K1 (192 core)

*OpenCV の取得 [#d36b3591]
-まずはgitでcloneする
-code.opencv.org がgitのhostingをやめてしまったので、githubからcloneする 
 ubuntu@tegra-ubuntu:~$ time git clone git@github.com:Itseez/opencv.git

 real    2m52.930s
 user    1m9.561s
 sys     0m21.632s
-そして、3.1.0をチェックアウトする 
 ubuntu@tegra-ubuntu:~$ cd opencv
 ubuntu@tegra-ubuntu:~/opencv$ git checkout -b Branch_3_1_0 3.1.0
 Switched to a new branch 'Branch_3_1_0'


*OpenCV3.1.0のビルド [#ocd8a98a]
-NEONの有効性も検証したいので -DENABLE_NEON:BOOL=ON する
-Tegra用のCUDAアーキテクチャさえビルドできれば良いので、 -DCUDA_ARCH_BIN=3.2 -DCUDA_ARCH_PTX= を付ける
--詳しくは[[OpenCV2.4.10.1のビルド#CUDAのアーキテクチャを指定した場合>OpenCV2.4.10.1のビルド#s7865aaf]] を参照
--[[https://developer.nvidia.com/cuda-gpus>https://developer.nvidia.com/cuda-gpus]]&note{cuda-gpus-official:[[💻 CUDA GPUS | NVIDIA Developer>https://developer.nvidia.com/cuda-gpus]], 2016-02-18閲覧};を参照すると、Jetson TK1 は3.2と書かれているので、ARCHを3.2にする
-ついでにexamplesもビルドする
-cmakeのfull logは[[こちら>https://gist.github.com/tomoaki0705/3b98d290b0ca99566649]]
-make allのfull logは[[こちら>https://gist.github.com/tomoaki0705/aabfbee12483a7111611]]
-make installのfull logは[[こちら>https://gist.github.com/tomoaki0705/f879ecada93fec8f3d44]]
**cmake [#y43b6ba6]
-[[ODROID-X2でOpenCV 3.1.0をビルド]]同様、out of source buildする
 ubuntu@tegra-ubuntu:~/opencv$ mkdir build
 ubuntu@tegra-ubuntu:~/opencv$ cd build/
 ubuntu@tegra-ubuntu:~/opencv/build$ time cmake -DBUILD_EXAMPLES:BOOL=ON -DENABLE_NEON:BOOL=ON -DCUDA_ARCH_BIN=3.2 -DCUDA_ARCH_PTX= ../
 (中略)
 
 real    0m54.217s
 user    0m42.775s
 sys     0m7.760s
**make all [#mb0ad23a]
-ARMの4coreをフルに使う
-Armの4coreをフルに使う
 ubuntu@tegra-ubuntu:~/opencv/build$ time make -j4 all
 (中略)
 
 real    49m18.453s
 user    173m36.759s
 sys     9m45.257s
-make -j all だけやると、gcc internal error とかが出たので、-j4 にする
-ざっくり49分ぐらいかかる
**make install [#saee1324]
-installにはsudoをつける
 ubuntu@tegra-ubuntu:~/opencv/build$ time sudo make install
 (中略)
 
 real    3m9.933s
 user    2m16.229s
 sys     0m28.954s
-/usr/local/include 以下に header が、
-/usr/local/lib 以下に .so ファイルが、
-/usr/local/share/OpenCV 以下に Haar特徴量のcascade classifierが
-それぞれインストールされる
