KandenAiHackathonPosture2 — エンジニア姿勢合成画像データセット

English Summary A large-scale synthetic image dataset of 52,500 images depicting engineers in four sitting postures (good, slouch, chin rest, stretch). Generated using Stable Diffusion v1.5 + ControlNet (Depth) from reference base images, with diverse variations in age, ethnicity, clothing, lighting, and camera artifacts. Designed for training posture classification models for real-time fatigue detection in office environments.


データセット概要

本データセットは、空間AIブレイン プロジェクトのために構築された、エンジニアの座り姿勢を再現した大規模合成画像データセットです。

実際のオフィスでの撮影データ収集が困難なため、画像生成AI(Stable Diffusion v1.5 + ControlNet Depth)を用いて、ベース画像の姿勢構造を保持しながら多様なバリエーションを自動生成しました。

学習での使用例

from datasets import load_dataset
from torchvision import transforms

dataset = load_dataset("SeiyaCM/KandenAiHackathonPosture2")
split = dataset["train"].train_test_split(test_size=0.1, seed=42)

label_map = {"01_good": 0, "02_slouch": 1, "03_chin_rest": 2, "04_stretch": 3}

transform = transforms.Compose([

想定ユースケース

  • エンジニアの姿勢分類モデルの学習・評価
  • オフィス環境でのウェルネスモニタリングシステムの開発
  • 合成データによる画像分類の研究・実験
  • ControlNet を用いたデータ拡張手法のベンチマーク

注意点・制約・バイアス / Limitations & Bias

  • 合成画像: 全画像がStable Diffusionで生成されたものであり、実際の写真ではありません。実環境での評価には実データでの追加検証が推奨されます
  • プロンプト由来のバイアス: 生成プロンプトにバリエーション(年齢、性別、服装等)を含めていますが、生成モデル自体のバイアスが反映される可能性があります
  • 姿勢の明確性: 一部の生成画像では、指定した姿勢が明確に表現されていない場合があります
  • 解像度: 生成画像はWebカメラ品質を模しており、高解像度な用途には適しません
  • 環境の多様性: オフィス環境を中心に生成しており、自宅や屋外環境のバリエーションは限定的です
