【摘要】 本文分析了OpenGL成像机理,给出了透视投影矩阵的推导过程,并建立了OpenGL成像与计算机视觉成像内外参数的对应关系。为验证本文的结论,我们设计了两种成像实验方案,并对成像实验的结果进行精度分析。实验结果证明了本文得到的OpenGL成像与计算机视觉成像参数之间的对应关系。根据上述理论,可以借助于OpenGL平台,模拟计算机视觉成像的过程,这对计算机视觉的虚拟实验具有重要的意义。更多还原

【Abstract】 This paper analyses the imaging mechanism of OpenGL and introduces the derivation of projective matrix; then,the relationship between vision imaging exterior and interior parameters and image matrix in OpenGL is constructed here.In order to verify the conclusions,we design two different kinds of experimental programs and give analysis of imaging accuracy.Experimental results prove the correctness of the theory proposed in this paper.Based on the above analysis,vision imaging process can be simulated by OpenGL.It is of significance to relate OpenGL imaging with vision imaging and can benefit simulation experiments in the fields of computer vision.更多还原
