Real-time ship motion prediction system

A lightweight approach to simulate a 2D radar coverage for virtual maritime environments

“…The server program of Vidusayura calculates the navigating ship positions and other movable objects' initial positions using motion prediction algorithms [3]. Calculated positions and the real time changes of the environment can be obtained as a raw data stream from the Vidusayura server by the connected clients.…”

“…Our work intends to provide a better training experience by modelling a 2D radar coverage for the Vidusayura virtual mar itime environment [3]. Although standalone radar simulation systems are optimised to improve the radar reading skills of trainees, it lacks in providing a real-time data feed from an environment the user currently interacts with.…”

Perception enhanced virtual environment for maritime applications

“…However combination of those two approaches can produce more effective and productive real-time six degrees of freedom algorithms. Consequently we combined above mention algorithms [28] and construct immersive virtual environment based on frame works proposed by Alexandre G. Ferreira et al and Xiuwen Liu et al We tested the new six degrees of freedom real-time ship motion algorithms in immersive environment with greater ethological validity and we discuss the ways of integrating real world geographical areas and real ships.…”

“…In this wave model it represents the height of the ocean surface by using the wave amplitude, wave number, wave frequency, direction of the wave and the initial phase. We published detail derivation of these algorithms in the proceedings of CGAT 2009 [28].…”

“…Comparison of predicted and measured ship motions gives encouraging outcome. We predicted these ship motions under several assumptions as mentioned by Sandariwan et al [28]. Simulating the real world scenario in a virtual word with similar conditions is not practical there are some problems.…”
