基于航空影像的航海模拟器视景快速建模方法

Fast Maritime Simulator Scene Modeling Method Based on Aerial Images

为解决航海模拟器视景建模中采用的人工建模方法效率低、精度差,处理工序复杂,不适用于大场景的三维建模问题,结合航海模拟器视景特点,运用倾斜摄影建模,程序化建模及图像语义分割技术,提出一种基于航空影像的组合建模方法,实现航海模拟器视景快速自动建模的目的。选取武汉天兴洲长江大桥附近水域进行建模,结果表明:该方法建模速度快,精度高,自动化程度高,且渲染效果真实流畅,符合航海模拟器中对于视景建模的需求。

Artificial Modeling using Computer Aid Design software are frequently applied in maritime simulator scene modeling,but with low accuracy, low efficiency and complicate workflow. It’s not the ideal method of modeling a large-scale area. A modeling method is proposed based on aerial images in combination with tilt photography modeling, procedural modeling and image semantic segmentation method. It’s a fast and highly automated modeling method specially for the maritime simulator. A water area near Tianxingzhou Yangtze River Bridge is chosen as the model. Experiment results show that the proposed method is of fast speed, high precision, high degree of automation, and the rendered scene is real and smooth and can meet the requirement of the maritime simulator.
