Amazon Linux 2 で OpenCV 4.5をビルドする
概要
Amazon Linux 2上でOpenCV 4.5をビルドします。Dockerを使います。
背景として、2020/12/01のre:Inventの発表にて、AWS Lambda でコンテナイメージが使えるようになりました。LambdaでOpenCVを使うには従来ややこしい考慮が必要だったと思いますが、コンテナにしてしまえば楽になるのではと期待し、まずはOpenCVのビルド手順を確認します。https://aws.amazon.com/jp/blogs/aws/new-for-aws-lambda-container-image-support/
なお、DockerもOpenCVも何も詳しくないので、何かまずい点は含むと思います。
ベースイメージ
amazonlinux:2.0.20200722.0
Dockerfile
OpenCVはcontrib込みです。
- Development Tools でCMakeは入るのですが、2系でした。OpenCVには古すぎるので、
cmake3を使用します。 - 以下のCMakeのパラメータは一例ですので、用途に応じて調整します。

CMakeの出力
上記でのCMakeの出力が以下です。筆者のローカルPC上のDocker Desktopでの結果です。
Video I/O系がごっそり抜けます。必要でしたら、ffmpegを入れたりGStreamerを入れたりすると良いかもしれません。
