The invention discloses a Bluetooth-based indoor positioning method. The method comprises the following steps of S1, arranging a plurality of Bluetooth positioning base stations and a plurality of fixed Bluetooth beacons indoors; S2, calculating preliminary positioning information of the Bluetooth beacon to be positioned; S3, selecting a fixed Bluetooth beacon closest to the area pointed by the preliminary positioning information, and marking the fixed Bluetooth beacon as a specific fixed Bluetooth beacon; S4, correcting a coefficient in the logarithmic distance path loss model formula; And S5, calculating the accurate position information of the to-be-positioned Bluetooth beacon. The invention discloses an indoor positioning method. wherein the Bluetooth beacon to be positioned is positioned each time; The coefficients in the logarithmic distance path loss model formula are dynamically corrected by using the fixed Bluetooth beacon to eliminate the influence of complex and changeable interference factors and obstacles on the Bluetooth signal transmission path on the positioning result, so that the to-be-positioned Bluetooth beacon is accurately positioned.
