船舶停靠过程三维虚拟仿真分析

The Analysis of Ship Docked 3D Virtual Simulation

船舶停靠过程建模对于船舶驾驶教学具有重要的应用价值。传统的船舶停靠过程三维虚拟模型在建立的过程中复杂性较高,模型逼真度较差。为此,提出基于特征动态优化算法的船舶停靠过程三维虚拟模型建立方法。根据采集的船舶停靠过程图像特征,计算船舶动态变化中心,为船舶停靠过程三维虚拟模型提供了准确的数据基础。提取船舶停靠过程图像的特征点,建立船舶图像特征网格模型,从而实现了船舶停靠过程三维虚拟模型的构建。实验结果表明,利用该方法建立船舶停靠过程的三维虚拟模型,能够有效提高模型的逼真度,效果令人满意。

The ship call at process modeling for ship＇s teaching has important application value.Traditional ship docked process complexity of 3 d virtual models in the process of establishing high, poorfidelity of the model.Therefore, based on the characteristics of dynamic optimization algorithm of shipdocking process of 3 d virtual model establishment method.According to the characteristics of the imageacquisition of ship docked process calculation of ship dynamic change center, for the ship dockedprocess of 3 d virtual model provides accurate data base.Image feature points extraction of ship dockedprocess, build image characteristics of ship grid model, so as to realize the ship dock constructionprocess of 3 d virtual model.Simulation experiment results show that using this method to establish theship docked in the process of 3 d virtual model, can effectively improve the fidelity of the models, theeffect is satisfactory
