坐标配准是协同定位的重要组成部分,一个合理的坐标配准体系可以体现协同定位算法的性能,否则可能会放大定位算法的误差。本文详细比较了基于最小二乘 (least square, LS)与基于普氏分析(Procrustes analysis, PA)的配准方法的设计思想、适用条件,并给出了基于普氏分析的坐标配准算法的详细步骤。利用协同定位算法(经典MDS和Levenberg–Marquardt算法)得到的实验数据,详细分析了锚节点数量、测距误差、网络节点平均连通度对配准精度的影响。实验表明,在2D和3D环境中,基于普氏分析的配准算法,其配准精度和稳定性都优于最小二乘法,配准误差降低约为20%。
- Abstract:
-
Coordinate registration is an integral part of cooperative localization. A good coordinate registration system can improve the performance of collaborative location algorithms; otherwise, it may increase their errors. This paper carefully compares the design ideas and applicable conditions of coordinate registration methods based on the least square (LS) method and Procrustes analysis (PA). Detailed steps of the coordinate registration algorithm based on PA are provided. Using the experimental data obtained from the cooperative localization algorithms (classical MDS and Levenberg-Marquardt algorithm), the effects of the number of anchor nodes, range error, and average connectivity of the network nodes on the registration accuracy were analyzed in detail. The experimental results showed that in 2D and 3D environments, the PA-based algorithm has better registration accuracy and stability than the LS-based algorithm, with registration error reduced by approximately 20%.
