抽象的。从理论上分析了微装配系统中双目显微视觉系统（MVS）的视觉分辨力和相交视场之间的相互影响。根据各种微装配任务的要求，如何在双目视觉系统的视觉分辨力与其在三维空间中的相交空间之间找到最佳折衷是一个显式问题。提出了一种基于Pareto优化的微装配系统双目MVS视觉分辨力和相交空间的折衷方法。通过对双目MVS的视觉分辨力和相交空间的建模与分析，将两个MVS的拓扑结构和光学放大率作为优化其物理特性的关键参数。一个多目标优化模型的基础上的Pareto优化方法的制定和使用找到Pareto最优的治疗，即Pareto前，这代表了最佳的折衷之间的视觉分辨率和相交空间的双目MVS。在此基础上，数值模拟了结构参数与优化解相对应的双目MVS的物理特性。因此，双目MVS与不同的参数建立在一个自动微装配系统与一个单一的机械手与五个自由度和实验测试。仿真和实验结果表明，所有的最优解，位于Pareto前沿，是最好的折衷之间的视觉分辨率和相交的双目MVS的视图空间。根据Pareto阵面，可以选择双目MVS的物理参数，以获得最佳的视觉分辨率与一定的相交的视图空间，反之亦然。
Abstract. Visual resolvability and intersection space of view of a binocular microscopic vision system (MVS) in microassembly systems have influences on each other via analyzing theoretically. According to requirements of various microassembly tasks, it is an explicit problem how to find the best compromise between the visual resolvability of binocular MVS and its intersection space of view in three-dimensional space. A Pareto optimization-based method to make the trade-off between the visual resolvability and the intersection space of view of binocular MVS with relevant fixed parameters in microassembly systems is proposed. Through modeling and analyzing on the visual resolvability and intersection space of view of a binocular MVS, the topology and optical magnifications of two MVSs are considered as the key parameters to optimize its physical properties. A multiobjection optimization model based on a Pareto optimization method is formulated and used to find the Pareto optimal cure, namely the Pareto front, which represents the best trade-off between the visual resolvability and the intersection space of view of a binocular MVS. On these bases, the physical properties of a binocular MVS with structural parameters corresponding to the optimization solutions are numerically simulated. Accordingly, a binocular MVS with different parameters is established on an automatic microassembly system with a single manipulator with five degree-of-freedom and experimentally tested. The simulation and experimental results indicate that all of the optimal solutions, which locate on the Pareto front, are the best trade-off between the visual resolvability and the intersection space of view of a binocular MVS. According to the Pareto front, physical parameters of a binocular MVS can be chosen to get the optimal visual resolvability with a certain intersection space of view and vice versa.
