Abstract

<p>An automatic rebar arrangement inspection system using a stereo camera was developed as a solution for maintaining the accuracy of reinforcement inspections while saving manpower and labor. Over 30 trials were conducted at 15 sites with different solar radiation and weather conditions and rebar arrangement specifications. And a trial of the proposed inspection system in combination with telepresence technology was conducted at the Nishiki Tunnel. Further, the inspection system was applied for the first time to construction phase confirmation at the Higashinegawa Bridge superstructure construction work site, which is a trial site of the “Project for Introducing and Utilizing Innovative Technology to Dramatically Improve the Productivity of Construction Sites” of the Ministry of Land, Infrastructure, Transport and Tourism. As a result, the inspection system was found to yield measurement accuracy sufficient to judge compliance with specified rebar spacing, reduce inspection time to about one third, and the time required for working at high places can be reduced, and contribute to improved safety by reducing time spent working at high elevations and preventing the spread of Novel coronavirus infections through its labor-saving effect.</p>
