摘要
在Luk偄cs算法的基础上,提出一种适用于三坐标测量系统的规则二次曲面重构方法,定义了圆柱、圆锥和圆环的最小二乘数学模型,给出了优化算法及迭代初值选取方法。通过仿真试验证明了该算法的正确性和稳定性,并将其应用于自主开发的测量软件系统GMeasure1.0。
A regular quadric restructuring method suitable for three-coordinates measuring systems was proposed based on the LukOcs＇ s algorithm. The least square mathematical models of cylinder, cone, and toms were defined, and the optimization algorithm and the method of selecting iterative initial values were presented. The validity and stability of this method were proved through a simulation test, and this method was applied to a self-developed measuring software Gmeasure 1.0.
