Abstract:
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  15 F,  15 B,  15 L,  15 R mounted in the respective places of a revolving upperstructure  3  in order to capture images for monitoring. A monitor  20  displays camera images  21 F,  21 B,  21 L,  21 R obtained by the cameras as well as an icon image  21 C of an image illustration of the hydraulic excavator  1 . The cameras  15 F,  15 L,  15 R are mounted at the distal ends of support arms  40 F,  40 L,  40 R to be located in positions jutting from a revolving upperstructure main unit  3 a  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.

Claim (Index 1):
A hydraulic excavator comprising:\n a revolving upperstructure; a catwalk provided so as to jut outward from the revolving upperstructure along a side of the revolving upperstructure; a cab installed in a forward position of the revolving upperstructure; a ladder installed in a rearward position of the revolving upperstructure; a plurality of monitoring cameras provided in a revolving range defined by a revolving radius of the revolving upperstructure and monitoring surroundings of the revolving upperstructure; a display controller configured to generate a display image from images captured by the plurality of monitoring cameras; a monitor for displaying the display image generated by the display controller; a first empty space existing between the cab and crawler belts forming a lower travel base; and a second empty space existing at a lower position of the ladder, wherein the plurality of monitoring cameras comprises: a front camera mounted to a first support arm jutted from a front of the revolving upperstructure; a left camera located above and in front of the catwalk and mounted to a second support arm jutted from a main unit of the revolving upperstructure in the lateral direction, the left camera having a field of view covering the first empty space existing between the cab and the crawler belts; a right camera located above the catwalk and mounted to a third support arm jutted from a main unit of the revolving upperstructure in the lateral direction; and a rear camera mounted to a fourth support arm provided at a rearward of the revolving upperstructure and having a field of view covering the second empty space existing at the lower position of the ladder, the display controller is further configured to: generate top view images looking downward, generate an icon image representing a planar image of the hydraulic excavator with an outline of the hydraulic excavator being shown in a graphic form, execute composite processing to display the top view images around the icon image, and display the top-view images to the monitor to include a part of a section hidden within a display region of the icon image.
