Abstract
Disclosed are a device and system for detecting ground subsidence by using a LiDAR technology. The system for detecting ground subsidence, which detects whether the ground has subsided within an area where the subsidence of the ground will be examined includes at least two reflection units installed in a structure disposed within an area where the subsidence of a ground will be examined and each configured to reflect light incident thereon, and a LiDAR device disposed within a preset radius from the structure and configured to detect whether the ground has subsided and the extent of the ground subsidence based on a distance difference between the LiDAR device and each of the reflection units.
