Development of bird's-eye view system in unmanned construction

Abstract

This paper describes a development of bird's-eye view system for teleoperation. Emergent disaster recoveries are important when natural disaters occur. Unmanned construction is used to recover from natural disasters such as landslide and pyroclastic flow. This construction method has no risk of secondary disaster because workers teleoperate construction machines at remote site. However, traditional unmanned construction is an inefficient way because captured images from a camera mounted on a construction machine usually has blind spots. We propose an easy calibration method to create bird's-eye view images which can reduce blind spots from multiple cameras. Our method helps workers understand environment easily and operate construction machines safely. We evaluate working efficiency by integrating our bird's-eye view system into actual unmanned constuction systems under actual field conditions.
