Table 3 Multi-dimensional evaluation framework for AIGC-generated reconstructions of Juanqinzhai interiors
Dimension | Indicators | Reference Basis | Assessment Criteria |
|---|---|---|---|
Geometric accuracy | Proportional parameters such as stage depth/total room depth, caisson (zao jing) diameter/bay width, partition (zhao) drop height/column height | Juanqinzhai SU model (“ground truth”) | Calculate absolute and relative errors; present deviations in tables or distribution charts |
Ornamentation | Motif density, color saturation, material texture | Historical archives, physical remains, restoration records | High consistency with historical reference = ✓; minor deviation = ∆; severe exaggeration/omission = ✗ |
Structural logic | Component proportions, spatial layout logic (e.g., enclosed vs. open) | SU model baseline; Qing Structural Regulations (Qingshi Yingzao Zeli) | Conforms to functional logic = ✓; partial misalignment = ∆; disproportion or structural incoherence = ✗ |
Contextual accuracy | Period features, stylistic consistency, symbolic hierarchy | Yangshi Lei architectural drawings, Qianlong-period documents | Matches Qianlong context = ✓; cross-period/stylistic mixing = ✗ |
Functional consistency | yanqin space: presence of luodi zhao, kang zhao, bisha chu to ensure privacy and enclosure; Theatrical space: xitai, tongjing hua, yuanguang zhao to establish performative arrangement | Prompt functional description; SU model; historical documents | Accurate function–component mapping = ✓; partial omission/confusion = ∆; evident misplacement or contradiction = ✗ |
