Abstract
The configuration includes a laser range finder (), a scan mechanism (), a distance-data acquiring unit (), a memory (), which stores installation state information and detection-area information for each measurement direction, a human-body determining unit (), a detection area-information updater (), which updates detection-area information under a predetermined condition, and the alert-output control unit (). The human-body determining unit () extracts a portion that possibly corresponds to a human body in an object that has invaded or moved, which is found out by comparison with the detection-area information based on the acquired distance information, and determines whether or not a rest of the respective extracted portions is a human body based on a movement state of each of the extracted portion in chronological order. The rest of the extracted portions excludes the extracted portions where a movement distance within a predetermined time is within a predetermined distance.
