ODROID-X2でOpenCV 3.0-betaをビルド

ODROID-X2でOpenCV

概要†

• ODROID-X2でOpenCVを3.0-betaで実行してみた。

前提準備†

• ODROID-X2でOpenCVを参照

OpenCVの3.0を取得する†

• まずはgitでcloneする
• そして、3.0.0-betaをチェックアウトする

  #geshi(bash){{ git clone git://code.opencv.org/opencv.git git tag -l git checkout 3.0.0-beta }}

OpenCV3.0のビルド†

• cmake してビルドする
• 今回は-DWITH_IPP:BOOL=OFFは不要だった

  #geshi(bash){{ cd opencv cmake -DBUILD_EXAMPLES:BOOL=ON -DBUILD_DOCS:BOOL=ON -DENABLE_NEON:BOOL=ON -DBUILD_TESTS:BOOL=ON . time make all ====== real 80m35.455s user 74m16.000s sys 2m49.270s }}

• Arm Cortex-A9(1.7GHz)でざっくり80minぐらいかかった
