| 全景成像技术在机器人、计算机视觉和虚拟现实领域有着重要的应用,与此同时也对其成像质量提出更高的要求。然而,对于此类大视场系统的设计较多地停留在光线追迹的方法,没有出现能对大视场像差进行参量化设计的方法。现将平面对称光学系统像差理论应用于此系统,得到关于光学参数的像质评价函数,采用差分进化算法解决多变量评价函数的优化问题,实现了一种折反射全景成像系统的优化设计,并用Zemax光线追迹软件证实了理论的正确性。结果表明,此类系统可以采用平面对称光学系统像差理论来优化设计,该思路是正确有效的。 |

| Catadioptric omnidirectional imaging technology is widely used in such areas as robots,computer vision and fictitious reality.Meanwhile,higher imaging quality is increasingly required.However,a large part of the current design methods of this type of large field optical system is restricted in the ray tracing method.Parametic design methods based on large field aberration are hardly found.The aberration theory of plane symmetric optical system is herein applied to this system.The metric function expressed as a function of optical parameters is developed,which is then optimized by the differential evolution algorithm.The design of one kind of catadioptric omnidirectional imaging system is realized by this method,which is confirmed by the ray tracing program Zemax.The result shows that this system can be optimized by this aberration theory,suggesting that the method is feasible and effective. |
