Abstract: 结合人眼光学建模和计算机图形学的真实感绘制技术,提出一种基于 Navarro 示意眼模型的人眼视觉真实感绘制方法。利用 Navarro 模型与传统的单透镜模型相比能够更精确地模拟人眼的特性,将 Navarro 模型引入视觉真实感绘制中; 采用光线追踪方法,加入非球面折射面的计算,精确地模拟人眼的成像特性。实验结果表明此种方法能够更精确地模拟人眼的视网膜成像,通过更改模型参数也能够 灵活地模拟人眼在不同视觉缺陷下的成像。
English Abstract: Combining human eye modeling technology and realistic rendering of computer graphics,this paper proposed a vision-realistic rendering method based on Navarro schematic eye model. Compared with the previous single lens model,Navarros model could simulate more vision characteristics of human eye. Based on Navarros model,utilizing the distributed ray tracing,and compute aspheric surface ray path,simulated more accurate retinal image. Further more,by adjusting the shape parameter of cornea and lens,to change the total diopter of the eye,rendered retina images with exact myopia and hyperopia of different levels. The experiment results indicate that this method can generate more realistic retina images reflected vision characteristics of the human eye,and by adjusting the parameter of the model,it can easily simulate the eye defect.
