【摘要】：自然场景的真实感绘制一直是计算机图形学研究的热点问题,海场景的真实感绘制是其中比较热门的问题之一,而且海场景的绘制在众多领域也有着广泛的应用。传统方法已无法满足海洋建模与绘制领域的研究需要,其具体体现为:海洋场景的规模难以使用传统方法直接进行模拟;传统方法无法模拟绘制出观测到的红外成像特征。针对于该领域的迫切需求,本文提出了一种可见光与红外光下的大规模海洋场景建模与绘制方法。针对于可见光特征,本文使用海洋波谱方法建模并绘制出了大规模海洋场景表面;针对于红外特征,本文将红外物流学原理引入到光滑粒子流体动力学中建模并模拟出了海面船舰的红外细节;并且,针对模拟规模问题提出了一种无边界的解决方案;最后,实现了可见光与红外波段下大规模海洋场景实时交互系统的实现。本文提出的模型除了模拟海面波浪及船舰航行导致的几何形状变化外,还能求得变化区域海水的红外物理特征变化,并从实验模拟的角度证明了红外特征的成像原因。这在海面目标的探测与救援、军事上的红外隐身与对抗等领域都有重要的应用价值。
[Abstract]:The realistic rendering of natural scenes is always a hot topic in computer graphics, and the realistic rendering of sea scenes is one of the most popular problems, and the rendering of sea scenes has been widely used in many fields. The traditional methods can not meet the needs of ocean modeling and rendering, which can not be directly simulated by traditional methods, and the traditional methods can not simulate the observed infrared imaging features. In order to meet the urgent needs of this field, this paper presents a modeling and rendering method for large-scale ocean scenes under visible and infrared light. Aiming at the feature of visible light, this paper uses the method of ocean spectrum to model and draw the surface of large-scale ocean scene, aiming at the infrared feature. In this paper, the infrared logistics theory is introduced into the smooth particle hydrodynamics to model and simulate the infrared details of the sea surface ship. In addition, a borderless solution to the simulation scale problem is proposed. The real-time interactive system of large-scale ocean scene in visible and infrared band is realized. The model presented in this paper not only simulates the changes of the sea surface waves and the geometric shape caused by the ship's navigation, but also can obtain the changes of the infrared physical characteristics of the sea water in the changing area. The imaging reasons of the infrared characteristics are proved from the point of view of the experimental simulation. It has important application value in the detection and rescue of sea surface targets, military infrared stealth and confrontation.
