摘　　要：深入探讨理想摄像机成像的过程与OpenGL透视投影的机理,在理论角度证明通过设定OpenGL参数可使虚拟图像与真实摄像机拍摄结果一致。对单摄像机成像、双摄像机成像、径向畸变以及镜面反射、结构光等几种摄影测量情况进行了仿真。提出一种可靠的验证方法,预先设定摄像机的内外参数,由OpenGL渲染生成不同位置的checkerboard图像,利用第三方标定程序包进行标定。标定结果与预先设定的摄像机参数一致,在实践上证明了理论推导的正确性。通过本系统可以了解摄像机在理想状态下成像的基本过程,为视觉系统标定、立体匹配、畸变校正、动态识别等大部分视觉算法的仿真奠定基础。The imaging essence of OpenGL and the nature camera were researched and compared,with proving that images rendered in OpenGL was in accordance with the real images generated in camera.The simulation system of monocular,binocular system,radial distortion and structural light were developed,and a verifying method with high confidence was provided.Setting the intrinsic and extrinsic parameters of camera,check board images were generated by virtual camera,then they were calibrated using the calibration toolbox which proved working correctly.The simulation was proved right with several different experiments such as single camera,stereo camera,distortion,reflectance and structure light.The system makes us know more about the fact of imaging without distortion which can be used for the measuring principle learning and research.
