Optical Real-Time Imaging Simulation System for Small Celestial Bodies Based on Graphics Hardware

摘要

In order to satisfy the real time request of optical Imaging Simulation System for small celestial bodies, this paper proposed a simulation method of the camera based on physical model, which is based on OpenGL pinhole imaging model and simulate optical camera parameters with graphic functions. By combining with rendering to texture and graphics hardware programming technologies, the article got sequence images of small celestial bodies, and achieved the physical effects.such as a Gaussian blur, smearing, noise, geometric distortion, motion blur and so on. At last, it was showed by experiments that simulation algorithms achieve real-time rendering requirements.
