Patent number: 10160383Abstract: 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.Type: GrantFiled: March 4, 2015Date of Patent: December 25, 2018Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Chieko Onuma, Ryo Yumiba, Yoshibumi Fukuda, Yukihiro Kawamata, Yoichi Kowatari, Moritaka Oota

Patent number: 10044933Abstract: 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.Type: GrantFiled: February 26, 2015Date of Patent: August 7, 2018Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Moritaka Oota, Yoichi Kowatari, Yoshihiro Inanobe

Patent number: 9463741Abstract: 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.Type: GrantFiled: March 19, 2015Date of Patent: October 11, 2016Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Yoshibumi Fukuda, Chieko Onuma, Hidefumi Ishimoto, Moritaka Oota, Yukihiro Kawamata

Publication number: 20160024758Abstract: Plural cameras are installed for the swiveling structure to monitor the vicinity of a working machine having a working member that is connected to the swiveling structure which is rotatably mounted on a traveling structure. The view field of two adjacent cameras partially overlap one another. A view point convertor converts the view point of the camera images acquired by the respective cameras to upper view point images. A display image creator creates an overhead view image composed of an illustration of the working machine as a plane view, and the upper view point images are converted from the converting view point convertor disposed around the illustration. An image display device is configured to show the overhead view image in the form of a plane view at least within a working reach region of the working member which is performing work by operation of the working member.Type: ApplicationFiled: August 26, 2013Publication date: January 28, 2016Inventors: Hidefumi ISHIMOTO, Moritaka OOTA, Yoichi KOWATARI, Yoshihiro INANOBE
