레이저스캐너를 이용한 지하공동의 용적측정 = Measurement Capacity of Underground Caverns using Laser Scanner

다국어 초록 (Multilingual Abstract)

When the capacity of underground caverns' structures is measured, a general surveying is difficult to decide an accurate section of irregular shape and a photographic surveying has problems on picture acquisition due to underground dusts, noise and lighting conditions, etc.
The present research measured accurate section decision and its capacity by using a laser scanner that can solve problems of the existing measurement system.
The laser scanner is being much used for 3-dimensional modeling such as topography, planimetric features and structures, etc. without a target by measuring arriving time of a laser pulse reflected after scanning the laser pulse and calculating space coordinates of the reflection position.
Accordingly, the present research carried out displacement measurement and section & capacity measurement of a archcrown of a tunnel by using a laser scanner in underground tunnel excavation work that a bridge construction is being executed.
