Abstract |
In order to improve timeliness of slope surface displacement monitoring, an integrated monitoring method was proposed that combined UAV photography and 3D laser scanning data to improve monitoring accuracy and achieve timely identification of monitoring points and calculation of displacement during slope deformation. The results show that this method based on high-accuracy point cloud contactless measurement can accurately calculate slope deformation with an absolute error being controlled within 1 cm, and its time consumption is about 27 minutes shorter than currently used real time kinematic (RTK), thus improving monitoring efficiency. © 2020 China Safety Science Journal.
