  • Patent number: 10321097
    Abstract: A perimeter monitoring device is configured to monitor a surrounding of a work vehicle and to display a monitored result on a display device. The perimeter monitoring device comprises a vehicle information detecting part, a plurality of cameras, a bird's-eye image display unit, a plurality of obstacle detecting sensors, an obstacle processing part, and a camera image displaying unit. The vehicle information detecting part detects a speed of the work vehicle. The cameras capture image data regarding the surrounding of the work vehicle.
