Low-Cost 3D Acquisition of Geometric Data for Living Heritage: Attempting to Record the Pudhu Mandapam, Madurai

Portable 360° photogrammetric surveys demonstrate the potential for non-destructive, cost-effective documentation of complex living heritage sites like the Pudhu Mandapam in Madurai. Conducted over two years with minimal disruption to daily activities, these rapid surveys provide valuable geometric data and condition mapping without invasive methods. While challenges remain—such as capturing intricate details in densely occupied spaces—the study highlights how advancements in low-cost 3D acquisition technologies can enable remote expertise and long-term monitoring of heritage degradation, reducing the need for physical surveys.
