摘要： A laser scanning sensor (100) includes a laser light-emitting element (11) configured to emit a pulse laser beam, a light-receiving element (12) configured to receive a returned reflected beam, a rotary polygon mirror (20) having a plurality of reflecting surfaces configured to change the travelling direction of the pulse laser beam, a drive motor (13) configured to rotate the rotary polygon mirror (20) in a predetermined direction, an encoder (14) configured to detect the rotation status of the rotary polygon mirror (20) and to generate a reference signal and trigger signals for the respective reflecting surfaces, and a control/calculation unit (30) configured to produce a projection pulse train in a specific pulse cycle after passage of a delay time counted from the generation of a trigger signal for each of the reflecting surfaces, and to acquire distance information per pulse, based on the time after the start of emission of the pulse laser beam before the return of the reflected beam. The delay time is set for each of the reflecting surfaces.

摘要： A laser scanning sensor (100) includes: a laser distance meter (110); a scanning mechanism (120); a distance data acquisition unit (130) which sequentially acquires distance information in each measurement direction; memory (160) which stores, as background distance information, a distance corresponding to an outer periphery of the detection area in each measurement direction; a mirror surface determination unit (135) which determines the presence of a reflecting surface when the distance information in continuous measurement directions corresponding to a predetermined width or less is greater by at least a predetermined distance than the background distance information in the respective measurement directions, and when this state changes thereafter by at least a predetermined rate in a predetermined time; a human body determination unit (140) which extracts a portion of the distance information that may correspond to a human body and which determines whether the extracted portion corresponds to a human body; and an alarm output control unit (150) which outputs a first alarm signal when the presence of the reflecting surface or the human body is confirmed.

摘要： The configuration includes a laser range finder (110), a scan mechanism (120), a distance-data acquiring unit (130), a memory (160), which stores installation state information and detection-area information for each measurement direction, a human-body determining unit (140), a detection area-information updater (140), which updates detection-area information under a predetermined condition, and the alert-output control unit (150). The human-body determining unit (140) 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.
