The invention provides an indoor positioning method, device and server. The method comprises the following steps: acquiring Bluetooth signal data collected by all anchor nodes within a current set period, wherein the Bluetooth signal data comprises an equipment identifier and Bluetooth signal intensity values; according to the equipment identifier, determining whether equipment sending Bluetooth signals is equipment to be positioned or not; and if the equipment sending the Bluetooth signals is the equipment to be positioned, determining the position of the equipment to be positioned according to a current positioning model of each anchor node, wherein the current positioning model of each anchor node is obtained through clustering of a signal intensity vector set generated by the Bluetooth signals sent by each anchor node within a previous set period. The method, device and server adopting the technical scheme has the advantages that the positioning model of each anchor node is dynamically updated according to an indoor environment, so that the positioning accuracy is high.
