INTRUSION DETERMINATION DEVICE, INTRUSION DETECTION SYSTEM, INTRUSION DETERMINATION METHOD, AND PROGRAM STORAGE MEDIUM

WIPO Patent Application WO/2023/286295

A1

This intrusion determination device is connected to a detection device to reduce occurrence of the detection failure or erroneous detection of a suspicious vehicle in a monitored airspace. The detection device is constructed by a combination of a plurality of types of detection sensors, which include at least a photographing device serving as a sensor that detects an unmanned aerial vehicle, among a plurality of types of detection sensors including a radar, a lidar, a passive radar, and the photographing device. An acquisition unit acquires a sensor signal output from the detection device. An image processing unit detects an unmanned aerial vehicle by object recognition processing from an image photographed by the photographing device. A determination unit determines whether or not a suspicious vehicle, which is an unmanned aerial vehicle not permitted to fly in the monitored airspace, has intruded into the monitored airspace on the basis of the result of detecting an unmanned aerial vehicle from the photographed image and a sensor signal output from a detection sensor other than the photographing device among the plurality of types of detection sensors constructing the detection device.
