<p><P>PROBLEM TO BE SOLVED: To provide an intrusion object detection device capable of detecting an intrusion object moving in front of vegetation existing in a monitoring area and suppressing erroneous detection caused by swinging of the vegetation. <P>SOLUTION: An intrusion object detection device 100 includes an imaging part 10 for acquiring a monitoring image of a monitoring area, a storage part 20 for storing a background image which is an image of the monitoring area in a state in which no intrusion object exists in the monitoring area and a vegetation area showing an area on an image of vegetation, change area extraction means 31 for extracting a change area where a luminance value has been changed by a difference between the monitoring image and the background image, and determination means 36 for calculating for the change area an intrusion object attribute value showing a degree of an intrusion object certainty which becomes lower in a case that the change area overlaps with the vegetation area than in a case that there is no overlap and determining whether the change area appears due to an intrusion object or not based on the intrusion object attribute value. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
