Abstract
This study presents a comparative analysis of terrestrial laser scanning (TLS) and mobile laser scanning (MLS) technologies for surveying transport infrastructure, using the example of a railway bridge on Brovarsky Avenue in Kyiv (Ukraine). The study used a Faro Focus 3D scanner for stationary scanning with an accuracy of 3 mm, and a FjD Trion P1 scanner with SLAM technology for mobile scanning. A comparison of point clouds showed a 2 cm discrepancy between the technologies, confirming the possibility of mobile scanning for rapid surveying of transport infrastructure. The study includes a detailed analysis of data processing workflows, SLAM algorithm errors, and an assessment of the performance of various laser scanning technologies applied to Ukrainian transport infrastructure.
