Zusammenfassung:	The invention discloses an indoor positioning method and system fusing WIFI and PDR positioning technologies, and the method comprises the steps: obtaining a WIFI positioning result of a to-be-detected target at a starting moment t0, and taking the WIFI positioning result as a starting position of the PDR positioning technology; obtaining sensor data from t0 to an intermediate moment t1, obtaining a PDR positioning result of the t1, and obtaining a WIFI positioning result of the t1; judging whether the error between the PDR positioning result of t1 and the WIFI positioning result exceeds a preset threshold value or not; if so, acquiring sensor data from the t0 to the termination moment tr, and obtaining a PDR positioning result of the tr; and if not, resetting the position corresponding to the WIFI positioning result of the t1 as the initial position of the PDR positioning technology, acquiring sensor data from the t1 to the tr, and obtaining a PDR positioning result of the tr. According to the technical sche
