A kind of method and apparatus are disclosed, for estimating ambulatory status, can estimate the walking of pedestrian. For estimating that ambulatory status is according to embodiments of the present invention: comprising steps of image receives leg walker The image for converting the leg area of leg is converted into polar coordinate system data Polar coordinate system is converted to data to orthogonal coordinate system data Estimate the orthogonal coordinate system data of central point branch The leg using central point that estimation walking is passed by. Therefore, the present invention can support stabilized walking and minimize the estimation of the user of error cause central point.Copyright KIPO 2017
