Abstract

A two-dimensional trajectory computation unit (45) which tracks positions in each picture computed by a human detection unit (44) and computes two-dimensional trajectories of individual people in each of the pictures is provided. A three-dimensional trajectory computation unit (46) executes stereo matching between the two-dimensional trajectories in each of the pictures computed by the two-dimensional trajectory computation unit (45), computes matching rates between the two-dimensional trajectories, and computes three-dimensional trajectories of the individual people from the two-dimensional trajectories that exhibit matching rates above a prescribed value.

Description

technical field

[0001] The present invention relates to a person tracking device and a person tracking program which detect and track each person existing in a monitoring target area. Background technique

[0002] There are a lot of elevators installed in high-rise buildings, but in order to transport passengers efficiently, for example, during rush hours in the morning and crowded lunch breaks, it is necessary to perform group management in which many elevators cooperate to operate.

[0003] In order to efficiently perform group management of many elevators, it is necessary to measure the movement history of passengers such as "how many people got on which floor and on which floor they got off", and provide the movement history to the group management system.

[0004] Conventionally, various proposals have been made regarding a person tracking technology that uses a camera to count the number of passengers and measure the movement of passengers.

[0005] As one of them, th...
