SURROUNDINGS MONITORING SYSTEM FOR WORKING MACHINE
First Claim
1. A surroundings monitoring system for a working machine, comprising:
- a monocular camera incorporated in the working machine and configured to pick up an image of the surroundings of the working machine;
a characteristic pattern extraction unit configured to extract characteristic patterns in the image based on a characteristic amount of the image;
a shadow profile extraction unit configured to extract a profile of a region regarded as a shadow of the working machine in the image, based on the characteristic amount of the image; and
an object detection unit configured to detect an obstacle existing around the working machine based on remaining characteristic patterns excluding characteristic patterns positioned on the profile extracted by the shadow profile extraction unit from the characteristic patterns extracted by the characteristic pattern extraction unit.

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.
