Other AbstractThe present application relates to a trajectory reconstruction method and apparatus, a computer device and a storage medium. The method comprises : acquiring inertial sensor data of a terminal device at a plurality of time points and signal strength data of a wireless fidelity network; generating, according to the signal strength data of the wireless fidelity network at each time point, initial positioning coordinates corresponding to each time point; generating, according to the inertial sensor data at each time point, a displacement vector corresponding to each time point; inputting the initial positioning coordinates and displacement vectors corresponding to the time points into a global positioning model, so as to obtain final positioning coordinates of the time points; and performing trajectory reconstruction according to the final positioning coordinates. By means of the method, a more accurate position estimation can be obtained in a complex object motion mode and a wireless propagation environment, thereby improving the accuracy of trajectory reconstruction.
