Movable Visualization System for Exterior Monitoring of Outdoor Infrastructures

Abstract

In order increase the work safety and efficiency of current human-based status evaluation of port infrastructures, the demand of adopting unmanned automatic evaluation system is growing. In this study, we developed a movable visualization system equipped with a multiple sensor module for exterior monitoring of outdoor infrastructures. The multiple sensor module consisted of two lidars, a stereo camera, and motion sensor. Movement of the multiple sensor module was implemented by remotely controllable toy car. We tested the functional performances of a dual lidar, a stereo, a motion sensor. The measurement error of GPS and IMU of the motion sensor 50 cm and were ±0.2 degrees. The merged lidar data and stereo helped to visualize the exterior status of the objects to be monitored.
