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 surroundings monitoring system for a working machine prevents its own vehicle shadow from having an influence on the detection of an object existing around the working machine. The surroundings monitoring system for a working machine includes: a monocular camera picks up an image of the surroundings of the working machine. A characteristic pattern extraction unit extracts characteristic patterns in the picked-up image based on a characteristic amount of the image. A shadow profile extraction unit extracts a profile of a region, which can be regarded as a shadow of the working machine in the image, based on the characteristic amount of the image; and an object detection unit detects an obstacle existing around the working machine based on the remaining characteristic patterns obtained by excluding a shadow profile characteristic patterns positioned on the profile extracted by the shadow profile extraction unit from the characteristic patterns.

Surroundings monitoring system for working 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

The vehicle exterior moving object detection system includes a surrounding-area image input section for capturing images in areas surrounding its own vehicle and delivering the captured images as surrounding-area images, a combined image constructing section for constructing a combined image including a result output from the detection of a moving object by combining the surrounding-area images, and an output section for presenting the combined image to the user. The vehicle exterior moving object detection system includes a movable-component region setting section for setting shapes and layout of movable components of the own vehicle in the surrounding-area images and calculating regions for the movable components of the vehicle, and a moving object detecting section for being supplied with the movable-component regions calculated by the movable-component region setting section and the surrounding-area images from the surrounding-area image input section, performing a process of detecting a moving object, and outputting a detection result.

Vehicle exterior moving object detection system

A vehicle peripheral obstacle notification system, used on a construction machine, detects a moving obstacle, gives composite display of the detected moving obstacle, and notifies a user thereof, the moving obstacle being at a location not appearing in a composite bird's-eye view obtained by onboard cameras acquiring images of the surroundings of the vehicle including an image immediately under the vehicle body. The system has a composite image formation part that extracts composite image formation areas from the surrounding images to compose a composite bird's-eye image. A moving obstacle is detected using the surrounding images and it is decided whether the detected position of the moving obstacle is inside or outside the composite image formation areas. If the detected position is determined to be outside the composite image formation areas, information about the detected position is extracted and an image thereof is output for superimposition onto the composite bird's-eye image.
