Laser Scanning a Palace: Algorithm Struggles with Small Details
This paper applies Brodu and Lague's morphological segmentation algorithm (CANUPO) to classify architectural components from terrestrial laser scanning data of a historical palace façade. The algorithm performed well on large complex shapes but struggled with smaller details, suggesting its applicability for general façade analysis but limitations for fine-grained modeling.
Possible Conflicts of Interest
None identified
Identified Weaknesses
Limited consideration of material properties
The study primarily focuses on visual and geometric analysis, neglecting a deeper exploration of material properties and their impact on segmentation accuracy. This limits the applicability of the findings to real-world scenarios where material variations significantly influence laser scanning data.
Limited generalizability due to single case study
The study's evaluation is based on a single case study, which may not be representative of the diverse range of architectural heritage sites. The findings may not generalize well to other buildings with different styles, materials, or levels of preservation.
Subjective evaluation based on manual segmentation
The study relies on manual segmentation as a benchmark for comparison, which introduces subjectivity and potential bias. A more objective evaluation metric, such as comparing against ground truth data obtained through other means, would strengthen the validity of the results.
Rating Explanation
This study presents a novel application of an existing algorithm for semantic segmentation of point clouds in the context of architectural heritage. While the methodology is sound and the results are promising for large-scale façade analysis, several limitations, such as the limited consideration of material properties, single case study focus, and subjective evaluation, prevent a higher rating. The study contributes to the field but requires further validation and refinement to enhance its practical applicability.
