新型方向性平面靶标及拓扑定位算法

Novel directional pattern and mapping location algorithm

设计了一种新型方向性平面靶标。区别于现有方向性靶标,该靶标仅由简单的圆组成,因此,设计和加工简单。针对靶标结构特点,提出了基于共线性规则的拓扑定位算法,实验证明,该算法处理准确、稳定可靠。根据应用需求,靶标易于改型使用,并提供了球和圆环型靶标的应用实例。

In this paper,a novel directional pattern is designed.This pattern is different with the current directional patterns,only composed of simple circle shapes.Therefore,the design and manufacture process is simple.According to the structural features,the mapping location algorithm based on collinear invariant ruler is proposed.Experimental results have proved that this algorithm works accurately and steadily.In addition,the design element can be revised easily due to the actual application requirement.The instances using spherical and toroidal pattern have been introduced finally.
