A Moving Object Indoor Tracking Model Based on Semiactive RFID

الملخص EN

Aimed at the weak anti-interference and low accuracy problem of moving object indoor tracking based RFID, a moving object indoor tracking model based on semiactive RFID is presented.

This model acquires scene location information through RFID low frequency triggers preinstalled, which can enhance the anti-interference ability.

This model adopts an improved particle filter algorithm, which can increase the diversity of the particles, overcome the particle impoverishment, and reduce the tracking error.

Simulation results indicate that the model can achieve better tracking performances.

Compared with standard particle filter, the improved algorithm performance is better in the capability of tracking accuracy and robust and is more suitable for indoor tracking application in the complicated environments.
