SYSTEM AND METHOD OF MOTION TRAJECTORY RECONSTRUCTION

摘要

A method of motion trajectory reconstruction is described as follows: obtaining angular velocity time-domain data and linear acceleration time-domain data from a traveling inertial sensor; performing a spectrum analysis to transform the angular velocity time-domain data into angular velocity frequency-domain data; choosing a main frequency wave of the spectrum from the angular velocity frequency-domain data; transforming the angular velocity frequency-domain data only having the main frequency wave into angular displacement time-domain data; obtaining linear displacement time-domain data by calculating the linear acceleration time-domain data and the angular displacement time-domain data; and reconstructing and displaying the motion trajectory of the inertial sensor according to the linear displacement time-domain data and the angular displacement time-domain data.
