摘　　要：以船舶航行提供可视化数字化视景为目的,提出基于VR技术的船舶航行视景数字化三维建模方法。通过采集地形数据、电子海图、三维实拍等资料,建立船舶视景模型文件、标物视景模型文件。使用3D MAX三维建模软件构建水面与陆域物标的三维模型,通过VR技术中Creator软件建立地形地貌模型。使用3D MAX三维建模软件建立船舶三维模型,并对模型进行网格重建、纹理映射以及组合渲染,从而得到完整的船舶航行视景数字化三维模型。实验表明,该方法可有效建立船舶、地标物三维模型,具有较好的船舶网格模型重构能力,可有效呈现船舶右回旋时航行视景数字化信息,应用效果较为显著。A digital 3D modeling method for ship navigation based on VR technology is proposed with the aim of providing a visual digital scene for ship navigation.By collecting terrain data,electronic charts,and 3D live photos,establish ship visual model files and target visual model files.Use 3D MAX 3D modeling software to build a 3D model of water and land targets,and use Creator software in VR technology to establish a terrain and geomorphology model.Use 3D MAX 3D modeling software to establish a ship's 3D model,and perform mesh reconstruction,texture mapping,and combined render-ing on the model to obtain a complete digital 3D model of the ship's navigation scene.The experiment shows that this meth-od can effectively establish three-dimensional models of ships and landmarks,and has good ability to reconstruct ship mesh models.It can effectively present digital information of the navigation scene of ships turning right,and the application effect is significant.
