Abstract

Teknolojideki gelişmelere paralel olarak mobil lidar sistemlerinin kullanım alanları günümüzde hızla artmaktadır. Özellikle GNSS ile konum belirlemenin mümkün olmadığı kapalı alanlarda SLAM algoritmalarının sağladığı avantajlar ile haritalama çalışmaları yüksek doğrulukta hızda yapılabilmektedir. Bu çalışmada, geliştirilen bir mobil lidar sistemi ile ağaçlık alan, kapalı alan ve dış mekanda yapılan ölçmeler sonucunda söz konusu alanların üç boyutlu modelleri üretilmiş ve üretilen modellerin doğruluk analizi yapılarak, GNSS ile konumlamanın mümkün olmadığı durumlarda mobil lidar sistemlerinin doğrulukları araştırılmıştır. Yapılan testler sonucunda geliştirilen mobil lidar sistemi ile ağaçlık alanlar, kapalı alanlar ve dış mekanlarda yapılan çalışmalar için sırasıyla ±2.1 cm, ±2.4 cm ve ±3.0 cm standart sapma değerleri elde edilmiştir. Bu sonuçlara göre sistemin orman envanterinin belirlenmesi çalışmalarında, kapalı ve açık alanlarda yapılacak mimari rölöve vb çalışmalarda kullanılabileceği öngörülmektedir.

Accuracy Assessment of Mobile Lidar System in Different Environments

Abstract

Depending on the developments in technology, the usage areas of mobile lidar systems are increasing rapidly today. With the advantages of SLAM algorithms, mapping studies can be performed with high accuracy, especially in areas where positioning is not possible with GNSS. In this study, with a developed mobile lidar system, three-dimensional models of the different areas were produced as a result of measurements made in woodland, indoor and outdoor areas, and the accuracy of the produced models was investigated in cases where positioning with GNSS was not possible. As a result of the tests, ±2.1 cm, ±2.4 cm and ±3.0 cm standard deviation values were obtained, respectively, for the studies carried out in woodland, indoor areas and outdoors with the mobile lidar system developed.
