%X The global navigation satellite system does not work ideally, because the satellite signal decays rapidly indoors due to the occlusion and absorption of building materials. As a result, the localization technologies based on beacons become state-of-art indoor localization technologies. The accuracy of these localization technologies is tightly related to the beacons' calibration accuracy. Based on the fact that beacons are usually set on the walls, a beacons self-calibration technology based on building information modeling is proposed to improve the performance of self-calibration. In the meantime, Cramer-Rao lower bound (CRLB) is used to analyse its performance in theory. Based on the semidefinite programming self-calibration algorithm, the proposed algorithm considers to use the building information modeling. CRLB analysis and simulation shows the proposed algorithm efficiently improve the accuracy of self-calibration.
