Overview

This sample pack contains real-world cooking demonstrations collected in an operating Chinese commercial kitchen in Zhongshan, Guangdong, China.

The data focuses on professional chef workflows rather than staged tabletop demonstrations. It includes synchronized or task-aligned multi-view video, egocentric footage, and metric depth data for evaluating robotics, embodied AI, imitation learning, and visual action understanding pipelines.

Related work such as EgoMimic suggests that egocentric human demonstration data can be valuable for scaling imitation learning, especially when paired with robot data or aligned sensing setups.

Key characteristics:

• Real commercial Chinese restaurant kitchen
• Professional chef with approximately 20 years of experience
• Egocentric, side-view, and overhead camera perspectives
• Intel RealSense D435I RGB-D capture for overhead view
• Chinese cooking tasks involving tool use, bimanual coordination, and fine-grained food manipulation

Note: Large egocentric videos in this sample pack are provided as 1080p preview encodings for easier download. Full 4K source recordings are available upon request.

Sample Pack Contents

Task 1 — Cutting Vegetables (切菜) · 3 camera views + depth

File	Description
egocentric_1080p.mp4	Head-mounted action camera, first-person view (1920×1080, 30fps preview)
side_view.mp4	Fixed side-view phone camera (1920×1080, 60fps, original capture)
overhead/overhead.mp4	Fixed overhead RealSense RGB (1280×720, 15fps)
depth/depth.hdf5	Aligned depth frames, float32 in meters (480×848, 2379 frames)

Task 2 — Wok Stir-Fry (翻炒) · 2 camera views

File	Description
egocentric_1080p.mp4	Head-mounted action camera, first-person view (1920×1080, 30fps preview)
side_view.mp4	Fixed side-view phone camera (1920×1080, 30fps preview)

Depth sample is included for Task 1. Additional depth recordings may be available depending on the task and capture setup.

Depth note: Pixels with value 65.535m indicate no valid depth return (sensor limit). Typical valid pixel rate: ~86%.

Preview PNG/JPG images are included alongside the videos for quick browsing.
