Fig. 12: Visualization of diagnostic results using digital measurement techniques.

This schematic illustrates the integrated methodology for multi-dimensional pathology analysis of the Temple of Kuan Tai and Tin Hau. It shows the fusion of 3D point clouds, infrared thermography, and optical data. The core workflow involves using the high-accuracy point cloud as a unified spatial reference. Pathological areas from 2D images are mapped onto the 3D model via manual feature-point matching, enabling reliable spatial localization despite challenges in fully automated pixel-level co-registration due to sensor differences. The figure highlights the potential for future algorithm development to enhance fusion automation and precision.
