This dataset is primarily developed for AI Agent simulation training and sim-to-real transfer research, targeting the demand for high-precision modeling of simulation environments in dynamic operation scenarios. It is generated using RealSense D455 depth cameras and GoPro camera arrays from the observation station of the State Key Laboratory of Intelligent Technology and Systems, Tsinghua University, and mainly records observational data including multi-view RGB-D image sequences, 3D point cloud data, NeRF/3DGS model parameters, and interactive scene assets. The data is sourced from real-scene scanning and photogrammetry of 3C production lines and spacecraft module segment scenarios. It adopts a multi-view synchronous acquisition scheme, with extrinsic parameter pre-alignment performed via COLMAP, Neural Radiance Field training conducted using Instant-NGP, and finally post-processed with MeshLab to generate plug-and-play USD format scene assets. Its generation method integrates computer vision and deep learning technologies, achieving high-fidelity reconstruction from real-world scenes to digital twin environments. The main contents of the dataset include high-precision NeRF/3DGS models with a spatial resolution up to millimeter level, multi-view texture mapping, scene geometric structures, lighting parameters, and other related data. All models have passed strict quality control procedures, ensuring that the key dimensional deviation between virtual and real scenes is ≤5.0%, and the signal-to-noise ratio (SNR) of reprojected images remains in the high-quality range, providing reliable guarantees of visual consistency and physical accuracy for simulation training. The dataset has a total volume of 100 MB, containing approximately 2 million multi-view RGB-D frames, with an acquisition period from September 2020 to December 2024. It follows the Creative Commons Attribution-NonCommercial 4.0 (CC BY-NC 4.0) license, with a 5-year retention period. By providing high-fidelity digital twin environments, this dataset effectively supports AI Agents in skill training and transfer validation within simulation environments, significantly improving skill learning efficiency and reducing the risks of real-machine debugging, and providing critical environmental support for hierarchical learning and cross-platform demonstration of complex operation tasks.
