The invention discloses an IMU data-based user indoor movement track matching method and relates to the field of IMU data-based user indoor movement track matching. The method solves the problem that the existing indoor movement distance and movement direction have relativity and an initial position and an end position of indoor movement on the map are unknown so that the indoor movement track cannot be matched and positioned on the indoor map. The method comprises constructing an indoor reference map by nodes to obtain a track set A of the indoor reference map, wherein the track set A has the node number the same to that of an indoor movement track, removing repeated node tracks to obtain a track set B, acquiring an indoor movement track set C by a torsion angle matrix GD of the indoor reference map, acquiring a matrix R of the shortest distance between track points of the indoor movement track set C by weight matrix W and D algorithms of the indoor reference map, comparing the matrix R of the shortest distance and a distance TD between adjacent nodes, and acquiring an indoor movement track set D by a threshold value theta . The method can be used for indoor positioning navigation.
