| Summary: | 碩士 === 國立中正大學 === 資訊工程研究所 === 101 === Camera simulation aims to enhance realistic rendering, lens design and augmented
reality by accurately simulating geometrical optics. Here our work focuses on optical
phenomena, such as depth of field, monochromatic aberration, distortion, and aperture
exposure, that are based on real camera lens architecture.
Our approach is modeling pixel equation using ray tracing algorithm to render scenes
after calculating the effect of lens refraction. We also provided an interactive user
interface to control camera parameters, allowing for visual display of the
corresponding camera lens system and of synthetic rendering result.
To promote the performance of ray tracing algorithm, we improved our system using
GPGPU programing language, CUDA, and OptiX ray tracing engine that is capable of
parallel processing massive multi-ray sampling. We further optimized the sampling
method for real-time pixel pupil calculation.
