Image Mosaicking and Localization Using a Camera Mounted on a Hanging-Type Wall Climbing Robot

Abstract

Owing to the revision of Japanese building law in 2008, the demand for wall inspections has been increasing. Currently, wall inspections are performed by workers using hammering devices; this involves dangerous work at high elevations. Therefore, we developed an inspection system using NOBORIN®, a hanging-type wall climbing robot. In this paper, we introduce the robot and its hammering inspection system, and propose a method for image mosaicking and localization using images captured from an equipped camera. The estimated values are used to correct the elevation motion(s) of the robot.
