摘要： To recognize an obstacle such as a working face which may be touched by a revolving upperstructure including a height position thereof at the time of a swing control. A plurality of first cameras 13 for forming bird's eye views which photograph obliquely lower parts of directions different from each other are arranged in a revolving upperstructure 3, a composite bird's eye view 20 is displayed on a display 15, second cameras 16R, 16L for photographing through images including corner parts from a rear end of the revolving upperstructure 3 to side parts within a visual field range are arranged in lower part positions of a swing frame 3a of the revolving upperstructure 3 so as to rotate following swing of the revolving upperstructure 3, and corner part through images 30R, 30L are displayed on the display 15 so as to be superimposed on the composite bird's eye view 20.

摘要： In an industrial machine, the work safety is further improved by eliminating blind spots from an image displayed on a monitor. A hydraulic excavator 1 which is the industrial machine is equipped with monitoring cameras 15F, 15B, 15L, 15R mounted in the respective places of a revolving upperstructure 3 in order to capture images for monitoring. A monitor 20 displays camera images 21F, 21B, 21L, 21R obtained by the cameras as well as an icon image 21C of an image illustration of the hydraulic excavator 1. The cameras 15F, 15L, 15R are mounted at the distal ends of support arms 40F, 40L, 40R to be located in positions jutting from a revolving upperstructure main unit 3a of the revolving upperstructure 3, so that a hidden area under the underside of a catwalk 14 provided on the revolving upperstructure 3 falls within the field of view.
