【摘要】：自然場(chǎng)景的真實(shí)感繪制一直是計(jì)算機(jī)圖形學(xué)研究的熱點(diǎn)問題,海場(chǎng)景的真實(shí)感繪制是其中比較熱門的問題之一,而且海場(chǎng)景的繪制在眾多領(lǐng)域也有著廣泛的應(yīng)用。傳統(tǒng)方法已無法滿足海洋建模與繪制領(lǐng)域的研究需要,其具體體現(xiàn)為:海洋場(chǎng)景的規(guī)模難以使用傳統(tǒng)方法直接進(jìn)行模擬;傳統(tǒng)方法無法模擬繪制出觀測(cè)到的紅外成像特征。針對(duì)于該領(lǐng)域的迫切需求,本文提出了一種可見光與紅外光下的大規(guī)模海洋場(chǎng)景建模與繪制方法。針對(duì)于可見光特征,本文使用海洋波譜方法建模并繪制出了大規(guī)模海洋場(chǎng)景表面;針對(duì)于紅外特征,本文將紅外物流學(xué)原理引入到光滑粒子流體動(dòng)力學(xué)中建模并模擬出了海面船艦的紅外細(xì)節(jié);并且,針對(duì)模擬規(guī)模問題提出了一種無邊界的解決方案;最后,實(shí)現(xiàn)了可見光與紅外波段下大規(guī)模海洋場(chǎng)景實(shí)時(shí)交互系統(tǒng)的實(shí)現(xiàn)。本文提出的模型除了模擬海面波浪及船艦航行導(dǎo)致的幾何形狀變化外,還能求得變化區(qū)域海水的紅外物理特征變化,并從實(shí)驗(yàn)?zāi)M的角度證明了紅外特征的成像原因。這在海面目標(biāo)的探測(cè)與救援、軍事上的紅外隱身與對(duì)抗等領(lǐng)域都有重要的應(yīng)用價(jià)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.
