A pedestrian tracking method and a pedestrian tracking device with a simple structure can estimate the motion of a pedestrian in images without using color information, making it possible to achieve a robust pedestrian tracking. The pedestrian tracking device (1) comprises: an image receiving means (2) for receiving, in time series, images continuously in time by an image capturing device (10); a pedestrian region selecting means (3) for sampling candidate pedestrian regions from an image received by the image receiving means (2) and for selecting a certain pedestrian region; a tracking means (4) provided in time series with the pedestrian region selected by the pedestrian region selecting means (3) for predicting motion of the pedestrian region and associating it with time direction by use of a skeleton model obtained by modeling a pedestrian, a distance-transformed image obtained from the pedestrian region and a Monte Carlo filter so as to track the pedestrian region; and a pedestrian trajectory display means (5) for displaying, in time series, the pedestrian region tracked by the tracking means (4).
