基于视频的船舶航道三维动态呈现系统设计

摘要

针对现有船舶航道三维呈现系统在实时性和动态交互性方面的不足，提出了一种基于视频的船舶航道三维动态呈现系统构建方法。首先，建立静态航道场景的三维模型和船舶模型库；其次，基于视频检测运动船舶并跟踪提取其动态信息；最后，根据所得的船舶动态信息，将三维静态场景模型与运动船舶模型融合，实现三维虚拟场景对视频场景的实时仿真。该系统应用于闸室段，以皂河二线段闸室为例，可以很好地模拟视频中的场景和船舶运动，具有较好的实时性和交互性。%In view of the defects of existing 3D ship rendering system in real -time and dynamic interactive,a method,based on video,is presented to construct the 3D ship and channel dynamic rendering system.First of all,a static 3D channel scene model and ship model library are established;Secondly,based on the video,the movement of ship is detected,and extract the dynamic information is tracked.Finally,according to the ship dynamic information obtained,enable the 3D static scene model and the motion of ship model integration and realize the 3D virtual scene real -time simulation of video scene.This system,applied in lock chamber and using ZaoHe second -line section of the lock chamber as an example,performs simulation in the video scene and ship motion well and has good interactive and controllability.
