first exemplary embodiment

[0044]FIG. 1 is an overall configuration diagram of the person counting system in a first embodiment. This person counting system is built into a retail store such as a convenience store, and includes camera 1, recorder (image recording device) 2, and PC (person counting device) 3.

[0045]Camera 1 is installed at an appropriate position in the store and the monitoring area in the store is imaged by camera 1. Imaged images obtained from the imaging are accumulated in recorder 2.

[0046]Input device 6 such as a mouse that performs various input operations of a user such as a monitoring person and monitor (display device) 7 that displays a monitor screen are connected to PC 3. Input device 6 and monitor 7 may be configured with a touch panel display.

[0047]PC 3 is installed in a security room of the store and the monitoring person (security guard) can browse through the imaged images inside the store imaged by camera 1 in real time using the monitor screen displayed on monitor 7. In additio...

second exemplary embodiment

[0123]Next, a second embodiment will be described. FIG. 14 is an explanatory diagram illustrating a count line set on the imaged image in the second embodiment.

[0124]In the first embodiment, the first area and the second area are separately set in the imaged image. However, in the second embodiment, the first area and the second area are set so as to be in contact with each other and the count line is set on the boundary between the first area and the second area.

[0125]In addition, in the first embodiment, any one of the first area and the second area is set as the count area according to the moving direction of the person, that is, according to whether the person moves in the direction of entering the store or the person moves in the direction of leaving the store, and when the moving line enters the count area, then, the person is counted. However, in the second embodiment, if the moving line crosses the count line, the person is counted.

[0126]The first area is the background area...

Abstract

A person counting device according to embodiments of the present invention counts the number of persons passing through a doorway based on an imaged image in which the surroundings of the doorway are imaged. The person counting device includes a moving line acquirer that acquires a moving line for each person detected from the imaged image, a person counter that counts the persons that have passed through the doorway based on the moving line, and a display information generator that generates display information which represents the number of persons that have passed through the doorway based on the counting results of the person counter. The person counter detects an interruption of the moving line in the vicinity of the doorway, determines a similarity between the background image of the doorway and the person image, and includes a deemed counter that deems that the person has passed through the doorway.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a person counting device, a person counting system, and a person counting method that counts the number of persons that have passed through a doorway based on an imaged image in which surroundings of a doorway for entering or leaving a predetermined place in a store or the like is imaged.[0003]2. Description of the Related Art[0004]In a store such as a convenience store, a monitoring camera system that monitors persons in the store using an image imaged by a camera installed in the store is widespread. However, if the number of entering persons and leaving persons are acquired by detecting the number of persons passing through the doorway of the store and counting the persons entering and leaving the store using an image imaged by a camera, it can be considered that there will be an improved way of effectively managing the store, and thus, it is possible to improve the sales and profits ...
