Title:
CONSTRUCTION MANAGEMENT SYSTEM FOR TUNNEL AND CONSTRUCTION MANAGEMENT METHOD FOR TUNNEL
Document Type and Number:
WIPO Patent Application WO/2024/062712
Kind Code:
A1
Abstract:
The present invention provides a construction management system which highly precisely generates a three-dimensional model representing an inner circumferential surface of a tunnel and each position of the tunnel, and a construction management method used for this system. The present invention comprises a first step (step S11) of defining a control point in a vicinity of an entrance of the tunnel and installing target markers on the inner circumferential surface of the tunnel, a second step (step S12) of executing measurement by a measurement means from different positions, and a third step (step S13) of generating a cylindrical model representing the inner circumferential surface on the basis of coupling of three-dimensional point cloud sets each obtained by the measurement executed from each of the different positions, and is characterized in that in the third step, a first three-dimensional point cloud set and a second three-dimensional point cloud set are coupled to each other through alignment using, as a reference, a point cloud representing the target markers included in both of the first three-dimensional point cloud set and the second three-dimensional point cloud set.
