摘　　要：本文基于超宽带技术搭建了一套室内定位系统,通过分布于室内固定位置的基站测量与目标物体标签距离的方法,采用基于到达时间估计的检测方法以及三边测量法解算出目标物体的坐标位置,并基于Python语言编写的坐标显示软件实时可视化。通过测量在室内的一辆华夫派小车的位置进行了试验,结果表明,本文提出的方法可以实现室内精度较高的实时定位,且定位精度在10 cm以内。In the paper,a set of indoor positioning system based on UWB technology is designed.Through the distribution in the indoor fixed position base station survey and objective method,the distance of the object label detection method based on time of arrival is estimated and calculated method of trilateration target coordinates of the object.Based on the Python language develop real-time visualization software to show the coordinates.By measuring the position of a waffle-pi car in the room.The test results show that the method proposed in this paper can achieve real-time positioning with high indoor accuracy,and the positioning accuracy reaches within 10 cm.
