RASPBIAN JESSIE に OpenCVが含まれているのでは

Raspberry Pi3 でOpenCV 2.4.13.1をビルドし、自作のOpenCVベンチマークプログラムを実行させてみた。
HaarLike実行中に、CPUの負荷を見ていると25%になっており、計算時間も予想より長くなっていた。

並列化が行われていないようなので、tbb周りを見てみるが、ビルド環境は従来通りで、おかしいところはないと思わる。
何度もビルドしてみたが、ビルド時のcmakeの情報を見てみるとtbbは有効になっている。

そこで、ベンチマーク実行時にconfigrationを出力させてみるので見てみた。
なぜかOpenCV 2.4.9.1 となっている。自分では、2.4.9.1などインストールしていないので、最初から含まれている可能性がある。


以下にconfigurationを示す。

tbbがoffになっている。
