DEVICE FOR MONITORING AREA AROUND WORKING MACHINE

摘要

The present invention provides a device for monitoring an area around a working machine which, even when there is a complex-shaped vehicle shadow in a photographed image of the area around the working machine, makes it possible to prevent the presence of the vehicle shadow from affecting the detection of an object present around the working machine. The present invention is provided with: a single-lens camera (6) for photographing an image of the periphery of the working machine; a feature pattern extraction unit (170) for extracting a feature pattern from the image on the basis of a feature amount of the image; a contour-of-shadow extraction unit (40) for extracting, on the basis of the feature amount of the image, the contour of an area in the image that can be considered to be a shadow of the working machine; and an object detection unit (180) for detecting an obstacle present around the working machine on the basis of the rest of the feature pattern extracted by the feature pattern extraction unit, with a contour-of-shadow feature pattern located on the contour extracted by the contour-of-shadow extraction unit excluded therefrom.
