Opis:: The aim of this paper is to use closed-circuit television (CCTV) to search and track moving objects in inland waterways. The area of the analysis is the part of the West Odra river between the Długi and Kolejowy bridges in Szczecin. The points of interest are chosen intentionally due to the risk of vessel collision with bridges. The results of the research into the implemented methods of tracking objects could be utilized in the future to extend inland navigation services, which could be used by the captains of the ships and River Information Services operational personnel as well.

Tytuł:: Method of image analysis in the process of assessment of ice occurrences

Opis:: The authors present the method of assessing the percentage of coverage of surface of the river by ice occurrences. This article concentrates on image analysis methods applied to assess the percentage of coverage of a waterway by ice occurrences. A decision, whether to stop navigation depends on an accurate calculation of amounts of ice floe and overall atmospheric conditions. For this purpose closed-circuit video camera images converted with the use of a set of edge detecting filters and subjected to quantitative analysis have been used. The correct assessment of ice occurrences may positively influence the navigation itself, as well as help in planning the use of inland waterways in transportation process.

Opis:: 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.
