The invention relates to a technical scheme of a joint filtering indoor single target tracking method, device and medium based on RSS map, including: setting and measuring RSSI information at a small number of reference point positions in a certain way, and assigning the reference point to each AP The RSSI information is replaced by the mean and variance of a Gaussian process. Through the RSSI probability model based on the standard Gaussian process, the RSSI fingerprints of all global reference points are obtained by model calculation, and the RSS map is generated. In the narrow space area, the unscented Kalman filter algorithm is used for target tracking, and in the open space area, the particle filter algorithm is used for tracking. The beneficial effects of the invention are as follows: it solves the difficulty in generating RSSI fingerprint database in large indoor places and the workload is large, and avoids the low tracking rate caused by the excessive calculation amount of the global particle filter; The problem of low tracking accuracy during movement. |
