昆虫复眼由许多小眼紧密排列而成,且每个小眼独立成像,通过处理和融合各个小眼获取的信息形成一个大视场的视觉系统。受昆虫复眼视觉成像机理的启发,提出了一种九复眼球面成像系统。根据九复眼球面成像的结构关系,分析九复眼球面光学系统成像机理和多视角成像的几伺光学变换关系,并在MATLAB平台中完成光学成像模型,得到各个视角的物像关系。最后对凸台模型的多视角图像中像点进行目标检测并测量,测量误差小于1%,从理论上证明了九复眼球面成像系统设计方案合理可行,方案对实现同级测量精度的球面复眼光学系统具有指导意义。
Insect compound eyes are closely arranged by many small eyes, and each small eye is independently imaged to form a large-field visual system by processing and integrating the information acquired by each small eye. Inspired by the mechanism of insect compound eye vision imaging, a nine-eye compound spherical imaging system was proposed. According to the structure of nine-fold spherical imaging, the relationship between several servo-optical transformations of the imaging mechanism and multi-view imaging of the ninefold spherical eye optical system is analyzed. The optical imaging model is completed in the MATLAB platform to obtain the object-image relationship of each perspective. Finally, the target detection and measurement of multi-view images in the boss model are carried out. The measurement error is less than 1%. It is theoretically proved that the design scheme of the nine-eye compound spherical imaging system is reasonable and feasible. Optical system is instructive.
