    Abstract: 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.

    Abstract: 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.
