How to Relate the OpenGL Imaging Process with Exterior and Interior Parameters of Photogrammetry
() Abstract
Based on deep analysis of the imaging mechanism of OpenGL in the sight of projective geometry, this paper have constructed the relationship between photogrammetry exterior and interior parameters and OpenGL projective matrix and proved their internal consistency. Then the transition equations of two imaging processes are derived, With above relationship and derivation, experiments have been conducted to simulate single static image, stereo image pair and motion orbit and pose in OpenGL. Experimental results prove the correctness of the theory proposed in this paper.
