The invention discloses a ship swaying forecasting visual system and method based on an improved Transform model, and belongs to the technical field of ship and ocean engineering. The method comprises the following steps: firstly, obtaining ship swaying attitude data and preprocessing the data to generate effective initial data; then, an improved Transform model is built, training is carried out, and meanwhile, a visual simulation system is built by applying Unity 3D; based on data measured in real time, the trained improved Transform model is applied to calculate the future motion attitude of the ship, and a forecast result is generated; and finally, transmitting the forecast result to a visual simulation system to obtain a visual simulation effect. According to the method, the three-dimensional dynamic scene is represented by adopting artificial neural network forecasting and visual simulation technologies, visualization of ship swaying attitude forecasting can be realized, a strong visual effect is provided for people, the sense of reality and immersion of a user on ship swaying are enhanced, and the effect of directly assisting in decision making is achieved.

    本发明公开了一种基于改进Transformer模型的船舶摇荡预报视景系统及方法,属于船舶与海洋工程技术领域。本发明首先通过获取船舶摇荡姿态数据及数据预处理,生成有效初始数据;然后搭建改进Transformer模型,并进行训练,同时应用Unity3D建立视景仿真系统;基于实时测量的数据,应用训练好的改进Transformer模型计算船舶未来运动姿态,生成预报结果;最后将预报结果传输至视景仿真系统,得到视景仿真效果。本发明采用了人工神经网络预报及视景仿真技术来表现三维动态场景,能够实现船舶摇荡姿态预报的可视化,给人以强烈的视觉效果,增强用户对于船舶摇荡的真实感和沉浸感,起到直接辅助决策的作用。
