| 摘 要： | 基于体视显微镜的显微立体视觉系统已经在微操作系统中得到应用．体视显微镜的2个子光路之间存在耦合关系,耦合程度与光路结构及物点在视场中的位置有关,建立了描述体视显微镜双光路耦合关系的相关函数,且对相关性进行了量化,量化结果可用于成像误差估计及模型的选择．实验结果表明,G-SLM双光路的相关性大于CMO-SLM双光路的相关性,小孔成像模型用于分析G-SLM成像时,存在较大成像误差．

| Abstract: | The micro stereovision systems with stereo light microscopes(SLM)have been applied to microma- nipulation systems.There is a coupling connection between the two optical paths of a stereo light microscope. The coupling intension corresponds with two factors.The first one is the structure of a stereo light micro- scope,and the second is the position of a random object point in the view field of a stereo light microscope.A correlation function is proposed to describe the coupling intension of two optical paths for the quantity of corre- lation between the couple optical paths of a stereo light microscope.The quantified results are applied to the error analysis of an imaging model.Experiments show that correlation of optical paths of CMO-SLM is little more than that of G-SLM,and error should be considered when a pinhole model is used to analysing the corre- lation. |
