Embodiment Construction
[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0055] Such as figure 1 As shown, the indoor positioning system based on the fusion of Bluetooth and MEMS proposed by the present invention includes a Bluetooth fingerprint positioning module 1, a MEMS positioning module 2, an extended Kalman approximation particle filter module 3 and a positioning result display module 4; The positioning module is respectively connected with the extended Kalman approximation particle filter module, and the extended Kalman approximation particle filter module is connected with the positioning result display module.
[0056] The Bluetooth fingerprint positioning module first completes the generation of the Bluetooth fingerprint database in the offline stage, that is, a plurality of anchor points are arranged in the indoor experimental area, and the RSS data sent by the user Bluetooth module in the indoor envir...
