１．Introduction
そもそも自力でチューニングする必要が無い方は、コチラのOpenVINO を導入することをオススメします。 OpenCV 4.1.1 が１０分ほどで導入可能です。
いつも参考にさせていただいている @mt08 さんの [メモ] ラズパイ OpenCV 4.1.1 ビルド時の__atomic_～～エラー対処 のノウハウをもとに、TBBのビルドとVFPV3/NEONを有効化した状態で、RaspberryPi3/4用 の OpenCV4.1.1 をビルドしました。 仮想環境を使用するため、実機でビルドするよりも格段に遅いと思います。 なお、TBBを組み込むことで若干OpenCVのパフォーマンスが上がるそうです。
このビルド環境は、過去の私の記事 QEMU4.0.0 のハードウェアエミュレーションモードで Debian Buster armhf のOSイメージをゼロから作成する方法 (Kernel 4.19.0-5-armmp-lpae, Tensorflow armhfビルド用) で構築した Raspbian 相当の環境を CPU 8 core 設定で使用します。 cmake時のワーニングをなるべく表示させないような手順を心がけました。

ちなみに私は RaspberryPi4 を所持していません。 仮想環境で作業することのメリットと言えば、RaspberryPiと同等の環境をあちこちの端末上に量産できることです。 ビルド好きな方は、いろいろなビルドパラメータで同時並行で試行することができますね。 はい、承知しております。 Docker や chroot でいいじゃん、とか冷たいこと言わないでください。
２．Environment
- Ubuntu 16.04 x86_64
- QEMU 4.0.0
- Debian Buster armhf (RAM 4GB, CPU 8 core)
３．Procedure
まず、 QEMU4.0.0 のハードウェアエミュレーションモードで Debian Buster armhf のOSイメージをゼロから作成する方法 (Kernel 4.19.0-5-armmp-lpae, Tensorflow armhfビルド用) でQEMUの仮想環境を構築します。そのうえで下記のコマンドにより、 CPU 8core かつ RAM 4GB の Debian Buster armhf を起動します。
Start_Debian_Buster
$ qemu-system-arm -M virt -m 4096 -smp 8 \
-kernel vmlinuz-4.19.0-5-armmp-lpae \
-initrd initrd.img-4.19.0-5-armmp-lpae \
-append 'root=/dev/vda2' \
-drive if=none,file=hda.qcow2,format=qcow2,id=hd \
-device virtio-blk-device,drive=hd \
-netdev user,id=mynet \
-device virtio-net-device,netdev=mynet \
-nographic
次に、下記の手順で OpenCV 4.1.1 をビルドします。

以上でビルドとインストールが完了です。 インストーラの生成方法は後日追記します。
そもそも、どんなビルドオプションがあるかなんか分からへんやん。という方へ。 ccmake という便利なツールがあります。 build フォルダへ移動したあとに ccmake .. を実行すると。。。
Install_ccmake
$ sudo apt-get install cmake-curses-gui
$ cd opencv-4.1.1/build
$ ccmake ..
下図のように表示されますので、 C を押すと。。。
このような表示に変わりますのでしばらく待ちます。
下図のように表示されたら、 E を押します。
すると、下図のような表示に切り替わります。 Enter キーを押すとパラメータが変更できます。 この画面のイメージでは１２ページ分の設定があることになっていますね。 OpenCVの設定、多すぎてカオスです。

@mt08さんのおかげで、Tensorflow のフルビルドに比べて１０００倍楽でした。
