A BASIC STUDY ON THE EXPRESSION OF "FEELING" ON THE SURFACE OF AN OBJECT USING LIDAR

Abstract

In Japan, technological development is being carried out using various ICT, IoT, AI, etc. in order to cope with a huge number of bridge inspections. In this study, we acquired the surface condition using LiDAR for the purpose of grasping the surface condition without contacting the infrastructure structures such as bridges. In addition, we conducted basic experiments on human tactile sensation in subjects. As a result of the correlation analysis using LiDAR data and human tactile data, it became clear that it is possible to grasp the "rattling" feeling without touching the object. On the other hand, it has become clear that it is necessary to use a higher-performance sensor for delicate irregularities on the surface of objects such as "smoothness" and so on.
