In the paper,a indoor 3D tracking system is designed based on UWB,by adding a supplementary matrix to solve time-of-flight ranging method (TOF) in the closed solution of the problem,combined with Kalman filter to realize the dynamic tracking labels.Both the base station and tags use STM32 series chips as the CPU,and DW1000 as the core communication component.The experiment results show that the system effect is good,not with the change of the indoor environment to increase the hardware cost.The system has robustness.
