2D-LiDAR-Sensor-Based Retaining Wall Displacement Measurement System
The displacement of retaining walls is measured using inclinometers in order to evaluate the safety of the wall. However, inclinometers have three problems: they (1) are difficult to install, (2) have local displacement detection, and (3) are measured ...
