Özet:

 Using the latest 3D measurement technologies to digitally preserve historic sites opens up new possibilities for mapping solutions. The use of laser scanners instead of traditional methods such as classical tachometry is becoming widespread. By improving the hardware, it is possible to increase the accuracy and sensitivity of the data obtained in 3D terrestrial laser scanning, the scanning speed, the maximum distance between object and object, and the volume of objects that can be measured. This paper evaluates the capability of terrestrial laser scanning technology for documenting facade data of historic bridges in 3D. This is followed by the creation of a 3D visualization model based on registered colorized point clouds. The study uses the FARO laser scanner system, a terrestrial laser scanner, to record the geometry data of the historical bridge. The color information of the geometric object was obtained from the camera integrated in the laser scanner. The average standard deviation between the point clouds of the laser scanned stations was calculated as 4.4 mm after registration. Our technological approach allows us to create a 3D color visualization model of the historical monument with automatic colorization process. The RGB values from the detailed high-resolution digital images were added to the 3D point cloud data using FARO Scene software. In this way, the 3D model can be visualized in a much more photorealistic way.

 Tarihi alanları dijital olarak korumak için en son 3B ölçüm teknolojilerini kullanmak, haritalama çözümleri için yeni olanaklar sunuyor. Klasik takeometri gibi geleneksel yöntemler yerine lazer tarayıcıların kullanımı yaygınlaşmaktadır. Kullanılan donanımların geliştirilmesiyle 3B yersel lazer taramada elde edilen verilerin doğruluğunu ve duyarlılığını, tarama hızını, obje nesne arasındaki maksimum mesafeyi ve ölçülebilen obje hacmini arttırmak mümkün olmaktadır. Bu makale, tarihi köprülerin cephe verilerinin 3B ortamda belgelenmesi için yersel lazer tarama teknolojisinin kapasitesini değerlendirmektedir. Bunu, kayıtlı renklendirilmiş nokta bulutlarına dayalı 3B görselleştirme modelinin oluşturulması takip etmektedir. Çalışma, tarihi köprünün geometri verilerini kaydetmek için yersel lazer tarayıcı olan FARO lazer tarayıcı sistemi kullanılmıştır. Geometrik nesnenin renk bilgisini yakalamak için lazer tarayıcıya entegre edilen kameradan elde edilmiştir. Lazer tarama yapılan istasyonların nokta bulutları arasındaki ortalama standart sapma kayıt sonrasında 4.4 mm olarak hesaplanmıştır. Teknolojik yaklaşımımız, otomatik renklendirme işlemi ile tarihi anıtın 3B renkli görselleştirme modelini oluşturma olanağı sağlamaktadır. Detaylı yüksek çözünürlüklü dijital görüntülerden RGB değerlerinin 3B nokta bulutu verilerine eklenmesi FARO Scene yazılımı kullanılarak tamamlanmıştır. Bu sayede 3B model çok daha fotogerçekçi bir şekilde görselleştirilebilmektedir.
