A method of determining inland vessel position using a single stationary, non-metric camera

This article presents the results of research on determining inland vessel position using a single stationary, non-metric camera, which was positioned on the Długi Bridge in Szczecin. Studies included a comparison of graphical methods (i.e. geometric transformation and the bunch of rays method) and analytical methods (i.e. 2D to 2D transformation and 3D to 2D transformation). The research material was a collection of video images of an inland vessel navigating the West Odra River between the Długi and Kolejowy bridges in Szczecin. The results of the research were compared to reference points determined using tachymetric surveys and material acquired by an Unmanned Aerial Vehicle (UAV) and the onboard GNSS satellite receiver with Real Time Kinematic (RTK) correction.
