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。
FROM amazonlinux:2.0.20200722.0

ENV OPENCV_VERSION=4.5.0

WORKDIR /

RUN yum update -y && \
    yum groupinstall -y "Development Tools" && \
    yum install -y \
        wget openssl-devel cmake3

RUN wget https://github.com/opencv/opencv/archive/${OPENCV_VERSION}.zip && \
    unzip ${OPENCV_VERSION}.zip && \
    rm ${OPENCV_VERSION}.zip && \
    mv opencv-${OPENCV_VERSION} opencv && \
    wget https://github.com/opencv/opencv_contrib/archive/${OPENCV_VERSION}.zip && \
    unzip ${OPENCV_VERSION}.zip && \
    rm ${OPENCV_VERSION}.zip && \
    mv opencv_contrib-${OPENCV_VERSION} opencv_contrib

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。
