摘要

蟋蟀是一种精细的室内定位系统，利用信标发射超声波和无线电波信号。然而，信标与侦听器之间的相对角度和距离对系统精度影响很大。本文提出了一种低成本的方法，通过增量误差补偿来提高系统精度。首先对直接影响到达时间差(TDOA)精度的超声检测误差进行了分析和实验验证。然后设计了一种基于总最小二乘(TLS)的误差补偿方法，进一步提高了蟋蟀的定位性能。实验结果表明，与原Cricket方法的9.06cm相比，补偿后的定位平均误差降低到5.60cm。误差的标准偏差由7.80cm减小到3.99cm。该方法为进一步完善现有超声相关距离测量方法奠定了基础。

Error Compensation for Cricket Indoor Location System

Cricket is a fine-grained indoor location system utilizing beacons transmitting both ultrasound and radio wave signals. However, the system accuracy is greatly impacted by the relative angle and distance between the beacon and listener. This paper proposes a low cost method to improve the system precision by means of incremental error compensation. The ultrasonic detecting error, which directly affects the accuracy of time-difference-of-arrival (TDOA), is first analyzed and verified via experiments. Then an error compensation method is designed based on total least squares (TLS) to further improve the Cricket’s localization performance. Experimental results show that the average error of localization is reduced to 5.60cm with compensation, compared with 9.06cm of the original Cricket method. The standard deviation of the errors is reduced from 7.80cm to 3.99cm. This method lays a foundation for further improving the existing ultrasound-related distance measurement method.
