PROBLEM TO BE SOLVED: To determine the sex of a pedestrian correctly using images picked up from various angles by image pickup devices.;SOLUTION: The images obtained by imaging the pedestrian by a plurality of image pickup devices are input in a sex determination device 1 in time series. A pedestrian region extraction part 12 of the sex determination device 1 generates a silhouette image from the difference of values between the pixels at the position of the pedestrian in an input image and the pixels at the position corresponding to the pedestrian in a background image. A person model construction part 13 configures a three-dimensional person model using the silhouette image and acquires the angle of each joint and the length between joints as parameters. A walking cycle cutoff part 15 calculates a walking cycle from the parameters. A feature quantity extraction part 16 acquires the feature of sex from the relation between the shoulder part and the waist part from a parameter string cut out for each walking cycle. A sex determination part 18 determines the sex by comparing the feature quantity with the feature quantity to which a special label is added in advance.;COPYRIGHT: (C)2010,JPO&INPIT
