Research on Measurement Method of River Earthwork by 3D Point Cloud Editor

Abstract

In recent years, many laser measurement instruments for measuring the three-dimensional shape of real space as point cloud data have been developed. Ministry of Land, Infrastructure, Transport and Tourism is pushing “i-Construction” to improve productivity by utilizing the three-dimensional information obtained by these lasers measuring instruments in construction work sites. Especially, in river management, survey results are accumulated in river management offices and development bureau throughout the country originating from a flood safety assessment project (LP project) utilizing airborne laser survey. Therefore, the opportunity to use point cloud data is increasing. However, the existing application for processing point cloud data has a problem that does not have any functions for the river management. Therefore, in this research, we propose a point cloud editor suitable for river management.
