Automated Part Recognition Technology of 3D Measurement data for Elevator Renewal

—Automated Dimension Extraction Technology of 3D Measurement data for Elevator Shaft—

Abstract

This paper proposes an automatic part recognition technology for 3D point cloud data of elevator shaft. The measurement system is used for elevator renewal proposal. The 3D point cloud data is measured by 3D laser scanner. A conventional method using 3D point cloud data are required by GUI-based human instruction. In order to reduce lead-time of elevator renewal proposal, Hitachi Ltd. has developed an automatic parts recognition technology and an automatic measurement technology for the 3D point cloud data of elevator shaft. The automatic parts recognition technology is characterized by graph network on voxel representation of point cloud data. These developed technologies enable to reduce 80% of field study time and drawing creation time.
