libfreenect2 python (r9y9 版)

r9y9/pylibfreenect2 を試してみることにした。

git clone https://github.com/r9y9/pylibfreenect2.git

remexre/pyfreenect2.gitのアンインストール

動きがイマイチだった、remexreさんが作ったpyfreenect2をアンインストール。

なんかエラーになったので、とりあえず、
/usr/local/lib/python2.7/dist-packages/pyfreenect2-0.0.0-py2.7-linux-x86_64.egg
を消した。

r9y9/pylibfreenect2 のインストール
sudo python setup.py install

    raise OSError("{}: is not found".format(libfreenect2_configh_path))
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/freenect2/lib

→エラーに変化なし。

のコードをPyCharmに貼り付けて実行したら、Kinect2の映像が見れた。
これで、Kinect2の深度データ付き映像 + Python機械学習 をする準備が整った。
ChainerかTensorFlowを使って、Deep Learningで何か学習させてみたい。
