Original Abstract Submitted
A gait analysis method includes collecting a two-dimensional gait video of a subject's gait situation during a preset time, which is captured using a camera; generating a three-dimensional coordinate system based on at least one frame of the two-dimensional gait video by receiving three-dimensional information of a capturing space; calculating three-dimensional feature point coordinates by receiving a plurality of feature points on the three-dimensional coordinate system, and calculating two-dimensional feature point coordinates for the plurality of feature points using resolution information of the camera; estimating mapping information between the three-dimensional feature point coordinates and the two-dimensional feature point coordinates; calculating a plurality of two-dimensional joint position information for the subject from the two-dimensional gait video; calculating a plurality of three-dimensional joint position information corresponding to the plurality of two-dimensional joint position information; and calculating gait parameters for the subject using the three-dimensional joint position information.
