OAK-D S2進める - HelloWorld

OAK-D S2の続き。

Hello World

公式ドキュメントを見ると、デモアプリを動かしてみた次のステップとして、HelloWorldプロジェクトでコーディングしてみよう、というのがある。

Hello World — DepthAI documentation | Luxonis

コーディングのしかたは、読んでみて、そういう感じかー、と。

これを実行してみた。

GitHubリポジトリクローン

リポジトリはここにあるので、これをクローンする。

github.com

git clone https://github.com/luxonis/depthai-tutorials/ c:\work\oak-d_test\depthai-tutorial

こんな感じのディレクトリ構造。

この中のhello-worldのほうを動かしてみる。

環境作成

Anacondaで新規作成。
Pythonバージョンは3.10にしておく。適当。

conda create -n depthai python=3.10
conda activate depthai

必要なパッケージのインストール。

pip install -r .\1-hello-world\requirements.txt

↓ 結果 (途中まで)

ということで、Python 3.10だとだめそう。

環境作り直しで、Python3.8でやり直してみる。

conda deactivate
conda remove -n depthai --all
conda create -n depthai python=3.8
conda activate depthai
pip install -r .\1-hello-world\requirements.txt

今度は大丈夫だった。

実行

python 1-hello-world/hello_world.py

ちゃんと動いた。

ここまで

サンプルコードを動かしただけだが、PythonからOAK-Dを扱える環境ができた、という意味はあるか。

次は手の認識をするサンプルがあるので、それをやってみる。
