FLOW LINE ANALYSIS SYSTEM AND FLOW LINE DISPLAY METHOD
First Claim
1. A flow line analysis system comprising:
- a plurality of cameras; and
a server that is connected to the cameras,wherein each of the camerascaptures an image of a differing imaging region,repeatedly generates a background image of a captured image of the imaging region,extracts flow line information regarding a staying position or a passing position of a moving object in the imaging region of the camera, included in the captured image, andtransmits the generated background image and the extracted flow line information of the moving object to the server at a predetermined transmission cycle, andwherein the serveracquires flow line analysis images based on superimposition between the background image of the captured image and the flow line information of the moving object for each camera,generates a wide-region flow line analysis image by using the plurality of acquired flow line analysis images, anddisplays the generated wide-region flow line analysis image on a display section.

Abstract
Displayed is a flow line analysis image in which the privacy of a person reflected in a wide imaging region is appropriately protected, and staying information or passing information of a person in the wide imaging region can be easily and accurately recognized. A camera includes an imaging section that captures an image of a differing imaging region for each camera, a background image generating section that repeatedly generates a background image of a captured image of the imaging region at predetermined timings, a flow line information analyzing section that extracts flow line information regarding a staying position or a passing position of a moving object in the imaging region of the camera, included in the captured image, and a transmitter that transmits the background image and the flow line information of the moving object to a server at a predetermined transmission cycle. A server includes an image generating section that acquires flow line analysis images based on superimposition between the background image of the captured image and the flow line information of the moving object for each camera, and generates a wide-region flow line analysis image by using the plurality of acquired flow line analysis images, and a display control section that displays the wide-region flow line analysis image on a display section.

5. A flow line display method for a flow line analysis system in which a plurality of cameras are connected to a server, the method comprising:
-
causing each of the cameras to capture an image of a differing imaging region, to repeatedly generate a background image of a captured image of the imaging region, to extract flow line information regarding a staying position or a passing position of a moving object in the imaging region of the camera, included in the captured image, and to transmit the generated background image and the extracted flow line information of the moving object to the server at a predetermined transmission cycle; and causing the server to acquire flow line analysis images based on superimposition between the background image of the captured image and the flow line information of the moving object for each camera, to generate a wide-region flow line analysis image by using the plurality of acquired flow line analysis images, and to display the generated wide-region flow line analysis image on a display section.
