In an industrial machine, the work safety is further improved by eliminating blind spots from an image displayed on a monitor. A hydraulic excavatorwhich is the industrial machine is equipped with monitoring camerasF,B,L,R mounted in the respective places of a revolving upperstructurein order to capture images for monitoring. A monitordisplays camera imagesF,B,L,R obtained by the cameras as well as an icon imageC of an image illustration of the hydraulic excavator. The camerasF,L,R are mounted at the distal ends of support armsF,L,R to be located in positions jutting from a revolving upperstructure main unitof the revolving upperstructure, so that a hidden area under the underside of a catwalkprovided on the revolving upperstructurefalls within the field of view.

Monitoring image display device of industrial machine

A slewing-type hydraulic excavator has a plurality of camerasfor respectively imaging toward different directions. A view point converting sectionperforms coordinate image data conversion to create overhead view images to look down from an upper position. A composite overhead view image creating sectioncreates a composite overhead view image P arranged around a graphic image of the hydraulic excavator. An interference scope indicating sectionindicates the scope of potential interference on the overhead view image with a surrounding obstacle at respective ground heights at the time of rotating the hydraulic excavator. A display image creating sectionproduces the composite overhead view image P together with interference scope which is displayed on a monitor.

Surrounding monitoring device for slewing-type work machine

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 camerasfor forming bird's eye views which photograph obliquely lower parts of directions different from each other are arranged in a revolving upperstructure, a composite bird's eye viewis displayed on a display, second camerasR,L for photographing through images including corner parts from a rear end of the revolving upperstructureto side parts within a visual field range are arranged in lower part positions of a swing frameof the revolving upperstructureso as to rotate following swing of the revolving upperstructure, and corner part through imagesR,L are displayed on the displayso as to be superimposed on the composite bird's eye view

Surroundings display device for swing working machine

A periphery monitoring device for a work machine includes imaging devices that capture an image of the surroundings of the work machine. An overhead view image is generated from the surroundings of the work machine based upon upper view-point images of the image devices. When generating an overhead view image of an overlap region of first and second upper view-point images relating to the images captured by the first and second imaging devices, the overhead view image generating unit, based upon a height of a virtual monitoring target, sets at least one of a first region in which the first upper view-point image is displayed and a second region in which the second upper view-point image is displayed, and also sets a third region in which a composite display image based upon the first and second upper view-point images is displayed.

Periphery monitoring device for work machine

When a to-be-monitored image exists in an image lacking from a bird's-eye image for surroundings monitoring though the to-be-monitored image is imaged by a camera for monitoring, the to-be-monitored image is securely displayed on a display. CamerasF,B,L,R are provided in a longitudinal direction and in a lateral direction of a dump truck, in playing bird's-eye imagesF,B,L,R acquired by converting view points of a through image imaged by each camera, so as to display a to-be-monitored image in a to-be-monitored image undisplayable area, each through image imaged by each camera is aggregated on one screen by an image aggregating unit, this aggregated screen is scanned by a to-be-monitored image detectorto detect the to-be-monitored image, and the to-be-monitored image is superimposed on a synthetic bird's-eye imagedisplayed on the displayand is displayed.

Surroundings monitoring device of vehicle

This invention has an object to assist for traveling operation of a self-propelled industrial machine to display underneath image of the self-propelled industrial machine on a monitor of a display device mounted in a operator's cab. The display device of the self-propelled industrial machine according to the present invention is provided for a dump truck, which comprises cameras having field of view to underneath of the dump truck, a symbol image storage section to store a symbol image which is symbolized the dump truck, a superposing process section to make transparent with a predetermined transparent ratio in the symbol image as a transparent region and to superpose an image taken by the camera on the area corresponding to the transparent region as underneath image, and a monitor mounted in a cab of the dump truck for displaying the symbol image composed by the superposing process section.

Display device for self-propelled industrial machine

A plurality of images captured by a plurality of cameras respectively to create a plurality of upper viewpoint images. Display images are extracted from the upper viewpoint images, and the extracted display images are synthesized to create an overhead image or bird's eye view image of surroundings, which has an image corresponding to an operating machine at a center of the bird's eye view image. When extracting each of the display images, a region of the display image extracted from the upper viewpoint image is expanded beyond the size of a standard extraction region on the basis of the set height of a mating face. Each of the extracted display images is adjusted to the size of the standard extraction region, and synthesized. Thus, any three-dimensional object (obstacle) present near the boundary between display images constituting the bird's eye view image is displayed.
