Being passing body several measurement manners and passing body several measurement manners which presume

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring the number of passing objects capable of estimating the number of the passing objects in a region captured in a video.;SOLUTION: A partial image generating section 10 generates a partial image from a continuous image sequence. A foreground detecting section 11 generates a foreground image representing a foreground region from the partial image. An on-image moving distance detecting section 12 detects a local moving distance on the image between frames in the detected foreground region. A moving distance coordinates conversion/representative moving distance calculating section 13 calculates a representative moving distance as a whole of an object group moving in each measuring direction of the number of passing objects by a method taking account of a relation between coordinates on the image and actual spatial coordinates on the basis of the local moving distance on the detected image. An in-image heads calculating section 14 estimates the number of objects captured in the image. A number of passers-by calculating section 15 calculates the number of passing objects between the frames in each measuring direction on the basis of the representative moving distance and the number of passing objects in each measuring direction.;COPYRIGHT: (C)2013,JPO&INPIT
