The invention provides an indoor positioning method and system and a computer readable medium, and the method comprises the steps: carrying out the positioning of a positioning target according to a UWB system and a preset algorithm, and determining a first position of the positioning target; positioning the positioning target according to an IMU system and preset parameters, and determining a second position of the positioning target; wherein the preset parameters at least comprise gyroscope error information and acceleration error information of the positioning target; and fusing the first position and the second position through a volume Kalman filtering algorithm to obtain a fusion result, and determining the current position of the positioning target according to the fusion result. The technical problem that only a target in a simple motion state can be positioned and a target in a complex motion state cannot be positioned in the prior art can be at least solved. 本申请提供了一种室内定位方法、系统及计算机可读介质，其中，一种室内定位方法，所述方
