Point Cloud Semantic Segmentation of Building Elements of Fatih Mosque, Istanbul

Abstract

The architectural heritage digital model is important for high-accuracy documentation, archive security, and research opportunities. This study focuses on the autonomous documentation of the digital model of Fatih Mosque’s facade elements. Fatih Mosque literature focuses on its restoration process, historical importance, and architectural values. The literature on the documentation of the mosque with current technological methods is limited. This study applies semantic segmentation on point-cloud data to detect facade elements. Point-cloud data was produced via photogrammetry from the southwest and northwest facades. The data was labeled with masonry wall, main load-bearing wall, column, window, entrance, staircase, arch, and spouts. CANUPO classifier in CloudCompare software is used for semantic segmentation. Changing the classification parameters in CANUPO increased the accuracy rate in predicting facade elements. This study contributes to the literature by providing autonomous documentation of the Fatih Mosque’s facade and a guide for using the CANUPO classifier in digital model production.

İstanbul Fatih Camii'nin Nokta Bulutu Semantik Segmentasyonu

Abstract

Mimari mirasın sayısal modellerinin üretilmesi, yüksek doğrulukta belgeleme, arşiv güvenliği, güncel yöntemlerle araştırma olanakları bakımından önemlidir. Bu çalışma Fatih Cami'nin cephe elemanlarının sayısal modellerinin otonom belgelenmesi sürecine odaklanmaktadır. Fatih Cami literatürü, caminin restorasyonu, tarihi önemi ve mimari değerleri konularını içermektedir. Caminin güncel teknolojik yöntemlerle belgelenmesi konusundaki literatür oldukça kısıtlıdır. Bu çalışmada Fatih Cami yapı elemanlarının otonom tespiti için nokta bulutu verisi ile anlamsal segmentasyon uygulanmıştır. Fatih Cami nokta bulutu verisi, caminin güneybatı ve kuzeybatı cephelerinden fotogrametri tekniği ile üretilmiştir. Nokta bulutu verisi, yığma duvar, ana taşıyıcı duvar, sütun, pencere, giriş kapısı, merdiven, kemer ve yağmur suyu oluğu yapı elemanları ile etiketlenmiştir. Anlamsal segmentasyon için CloudCompare yazılımındaki CANUPO sınıflandırıcı aracı kullanılmıştır. CANUPO ile sınıflandırma parametreleri düzenlenerek, farklı yapı elemanlarının tahminindeki doğruluk oranı arttırılabilmiştir. Bu çalışma hem Fatih Cami’nin cephe elemanlarının otonom belgelenmesi ile, hem de sayısal model üretiminde CANUPO sınıflandırıcı kullanımı için bir rehber niteliği oluşturarak literatüre katkı sağlamaktadır.
