The invention discloses a sliding window based fingerprint technique and sensor fused indoor positioning method. The method includes that the entire positioning process is divided into multiple sections to eliminate accumulated errors brought by long-term positioning, each section is defined as a window, one location coordinate is acquired in each window via proportional weighing of fingerprint technique positioning results and PDR (pedestrian dead reckoning) positioning results, the location coordinate serves as the initial position used for calculating each step of the positioning results behind users, locations of all the windows are combined finally, and the locations of pedestrians can be accurately positioned. With the method that PDR is taken as the main positioning scheme, the positioning result of the WiFi fingerprint technique is taken as assistance to correct the accumulated errors brought by the PDR positioning result, and features of the PDR positioning result stable in short term and good in positioning accuracy are utilized.
