High-fidelity 3D Buddhist sculpture reconstruction from single images using domain-adaptive diffusion
Year: 2025
Type: article
Abstract: Buddhist sculptures face preservation challenges due to physical degradation and limited accessibility. We present a framework for high-fidelity 3D reconstruction from single 2D images, integrating modified Stable Diffusion architecture with a novel Instant and Consistent Mesh Reconstruction (ISOMER) algorithm. Our method employs multi-stage processing: multi-view image generation, high-resolution refinement via ControlNet and Real-ESRGAN, and normal map prediction. Enhanced by a curated dataset of 672 Buddhist sculptures, we introduce Explicit Target optimization in ISOMER, significantly improving fine iconographic detail preservation. Experimental results demonstrate superior performance over state-of-the-art methods, achieving 7.1% reduction in Chamfer Distance and 2.2% increase in F-Score. The framework captures intricate surface textures and stylistic elements crucial for art historical research and digital conservation, though limitations persist in reconstructing highly reflective or translucent materials.
