Bu çalışma, kriminal olay yerlerinin dijital olarak belgelenmesi ve analizinde yersel lazer tarayıcı teknolojisinin etkinliğini değerlendirmektedir. Olay yerinin doğru, hızlı ve detaylı bir şekilde belgelenmesi, adli bilimlerde delil bütünlüğünün korunması ve olayın yeniden yapılandırılması açısından kritik öneme sahiptir. Çalışmada, FARO Focus S350 modeli bir YLT cihazı kullanılarak örnek bir suç mahalli detaylı bir şekilde taranmış ve elde edilen 3B veriler analiz edilmiştir. Sonuçlar, YLT teknolojisinin yüksek hassasiyet ve doğruluk sunduğunu, olay yerindeki tüm detayları eksiksiz bir şekilde kaydettiğini göstermiştir. Ayrıca, bu teknoloji, adli süreçlerde görselleştirme ve analizleri desteklemek için güçlü bir araç olarak değerlendirilmektedir. YLT'nin sağlayabildiği detaylı ve hızlı veri toplama kapasitesine rağmen, parlak yüzeylerde ölçüm hataları ve cihaz maliyeti gibi sınırlamalar dikkat çekmiştir. Gelecekteki çalışmalarda, tamamlayıcı teknolojilerin entegrasyonu ve cihaz performansını artıracak yazılım geliştirmelerinin yapılması önerilmektedir. Bu bağlamda YLT, adli bilimlerde dijital dönüşümün önemli bir parçası olarak öne çıkmaktadır.

Utilization of Terrestrial Laser Scanning in the Digital Documentation of Crime Scenes

Öz

This study evaluates the effectiveness of terrestrial laser scanning (TLS) technology in digital documentation and analysis of crime scenes. Accurate, fast, and detailed documentation of crime scenes is critical for preserving evidence integrity and reconstructing events in forensic investigations. In this study, a FARO Focus S350 TLS device was utilized to scan a simulated crime scene in detail, and the resulting 3D data were analyzed. The findings demonstrate that TLS technology provides high precision and accuracy, capturing all details of the crime scene comprehensively. Moreover, this technology is considered a powerful tool for supporting visualization and analysis in judicial processes. Despite its detailed and rapid data acquisition capabilities, limitations such as measurement errors on reflective surfaces and the high cost of devices were noted. Future studies are recommended to explore the integration of complementary technologies and the development of software to enhance device performance. In this context, TLS emerges as a significant component of the digital transformation in forensic science.
