Overview of AIGC in Heritage Reconstruction
This paper presents a novel approach to digitally reconstruct traditional Chinese timber components, specifically Qing-period interior canopies, using Artificial Intelligence Generated Content (AIGC). It addresses critical challenges such as fragmented archival data and the inefficiency of traditional modeling methods, particularly in capturing intricate ornamental details. The study develops a comprehensive workflow from semantic extraction to model validation, demonstrating AIGC's capability to generate visually coherent and stylistically rich architectural elements, thereby bridging gaps in historical documentation.
The integrated approach leverages AIGC for rapid prototyping and stylistic variation, offering a powerful tool for digital heritage conservation. It also lays the groundwork for developing robust component ontologies and enriching Building Information Modeling (BIM) libraries, crucial for future architectural preservation and study initiatives.
Methodology: Integrated Workflow for AIGC-based Reconstruction
The research establishes a systematic workflow that transforms fragmented historical data into structured semantic inputs for AIGC. This multi-step process ensures both semantic accuracy and stylistic consistency, crucial for the digital reconstruction of complex architectural components.

The comparative analysis demonstrates Midjourney's superior performance in stylistic representation and ornamental richness, making it the primary platform for this research. While AIGC excels in generating coherent and stylistically consistent images, precision in structural logic and dimensional accuracy remains a challenge, necessitating expert semantic annotation and validation.
Discussion & Implications: AIGC's Future in Heritage Conservation
Bridging the Gap: AIGC for Fragmented Heritage Data
This study pioneers a novel workflow for digital heritage reconstruction, moving beyond visualization to semantic-driven generation. It demonstrates AIGC's capability to transform fragmented textual records and schematic drawings into visually expressive and semantically interpretable digital assets.
Key Takeaways:
- Semantic-Driven Reconstruction: AIGC acts as a mechanism to bridge historical archives and digital reconstruction, creating coherent, usable digital assets from incomplete data.
- Hierarchical Accuracy: AIGC outputs show high dimensional stability in primary load-bearing members (e.g., support posts) but accumulate greater distortions in decorative zones due to stylistic oversaturation.
- Limitations & Future Work: While strong in stylistic expression, AIGC currently lacks structural logic, dimensional precision, and node-level detail. Future efforts will involve expanding sample size, incorporating expert evaluations, and integrating AIGC with established HBIM workflows to address these limitations.
This approach highlights AIGC's potential to develop component ontologies and expand BIM libraries, supporting rapid prototyping and stylistic diversity for heritage conservation.
The research emphasizes that AIGC, in its current form, is a complementary resource rather than a direct replacement for precise architectural documentation. Its true value lies in augmenting existing methods and enabling new avenues for historical reinterpretation and preservation.
