<p><P>PROBLEM TO BE SOLVED: To provide an entrance/exit monitoring method and an entrance/exit monitoring system, in which following is detected, and warning is given to an illicit entrance to a management area by the following. <P>SOLUTION: In this entrance/exit monitoring method for detecting the following by detecting reactions of areas 1-5 set in an authentication area, appropriate image processing is performed according to the passing stage (passage of time) of a person who passes through the authentication area. When camera images successively inputted from a following detecting camera are image processed to detect the following, it is determined which of standby processing, normal direction determination processing, normal direction optimization processing, normal direction escape processing, reverse direction determination processing, reverse direction optimization processing, reverse direction escape processing and following processing the next processing is, the following in entrance to the management area is detected through the standby processing, the normal direction determination processing, the normal direction optimization processing or the normal direction escape processing, and the following in leaving the management area is detected through the standby processing, the reverse direction determination processing, the reverse direction optimization processing or the reverse direction escape processing. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
