METHOD OF AUTOMATED OBTAINING OF VESSEL PARAMETERS FROM THE VISUAL INTERFACE OF THE NAVIGATION SIMULATOR

Abstract

The article proposes a method for automated reconstruction of navigational and control parameters of a vessel based on the analysis of a navigation simulator’s visual interface, without accessing its internal telemetry modules. The relevance of the study arises from the fact that most existing approaches rely on service logs or digital data streams, access to which depends on the architecture of a specific software platform. Such dependence limits experimental reproducibility, complicates cross-platform comparison of results, and reduces the universality of the conclusions obtained.

The proposed approach treats the screen space as a structured information field in which stable zones corresponding to individual indicators are localized. After configuring these zones, graphical and numerical interface elements are automatically transformed into synchronized time series of motion parameters. The reconstruction rate is aligned with the update frequency of interface indicators and, under appropriate technical conditions, can reach up to 10 Hz. The resulting multidimensional dataset enables analysis of vessel trajectory, transient regimes, response delays, and the relationship between control actions and vessel dynamics.

Experimental validation was carried out using a full-mission bridge simulator. For heading, the mean absolute reconstruction error did not exceed 1°, while for propeller shaft revolutions it remained below 2% of the nominal value. The obtained time series preserve the physical sequence of maneuvering processes, reproduce characteristic extrema, and do not exhibit significant phase distortions. The results confirm the feasibility of using the visual interface layer as an independent and universal source of experimental data for studies of ship motion dynamic
