已经开发出一种计算机模拟技术来研究已建立的和新颖的激光多边定位方案的性能。该模型侧重于分析系统配置变化的影响，优化系统自校准过程并评估体积测量误差传播。精心优化系统配置和自校准规划，显着降低系统自校准和测量的不确定性。比较具有不同数量测量站的多点定位系统的模拟性能，例如四个、五个和六个站，量化通过增加站数所获得的性能改进。本文提出了优化多点定位和测量计划以及最小化测量不确定性的具体建议。已经定义了一种用于小型人工制品高精度校准的新颖的连续多点定位装置，并进行了测量以支持此处介绍的分析。
A computer simulation technique has been developed to investigate the performance of established and novel laser multilateration schemes. The models focus on analysing the impact of variations in system configuration, optimizing the system self-calibration process and evaluating the volumetric measurement error propagation. Careful optimization of the system configuration and self-calibration planning significantly reduces the uncertainty of system self-calibration and measurement. Comparing the simulated performances of multilateration systems with different number of measurement stations, e.g. four, five and six stations, quantifies the performance improvement obtained by increasing the number of stations. Specific recommendations for optimization of multilateration set-ups and measurement plans and for minimizing measurement uncertainty are set out in the paper. A novel, sequential multilateration set-up for high-precision calibration of small artefacts has been defined, and measurements have been made to support the analysis presented here.
