FLOW LINE ANALYSIS SYSTEM AND FLOW LINE DISPLAY METHOD

摘要

The purpose of the present invention is to display a flow line image such that information on people who are stationary or passing through in a large imaging area can be easily and accurately ascertained while properly protecting the privacy of the people appearing in the large imaging area. Camera devices are each provided with: an imaging unit for capturing an image of an imaging area specific to the each camera device; a background image generation unit for repeatedly generating a background image for the captured image of the imaging area at predetermined times; a flow line information analysis unit for extracting flow line information pertaining to positions of moving bodies which are stationary or passing through in the imaging area included in the captured image; and a transmission unit for transmitting the background image and the flow line information of the moving bodies to a server device in a predetermined transmission cycle. The server device is provided with: an image generation unit for generating, upon acquiring from each of the camera devices a flow line analysis image based on the background image of the captured image superimposed with the line flow information of the moving bodies, a large-area flow line analysis image by using the acquired multiple line flow analysis images; and a display control unit for causing a display unit to display the large-area flow line analysis image.
