Abstract: Disclosed is an air-ground integrated landslide monitoring method and device. The monitoring method comprises the following steps: step one, performing high-precision (centimeter-level) vertical aerial photogrammetry and oblique photogrammetry on a monitored area by using an unmanned aerial vehicle, and quickly generating a digital topographic map, a digital orthographic map and a digital surface model; step two, performing accurate and intensive monitoring on the monitored area through a monitoring device; and step three, finally sending obtained data to a processor, and after the monitoring data are processed by the processor, sending the data to a remote-control center, so that real-time transformation and spatialization of dynamic landslide monitoring information are achieved. The present disclosure also provides a landslide monitoring device. The landslide monitoring device comprises a control box, a bottom plate and an unmanned aerial vehicle.

Abstract: Disclosed is a Beidou communication-based integrated monitoring system for a slope surface crack, which in particular relates to the field of geological disaster monitoring. Due to a certain trend of landslide damage degrees, and consequent offsets of a slope area over time, monitoring points pre-arranged possibly become non-optimal monitoring points with undesired monitoring effects. In view of this, the present disclosure includes an arrangement module, a monitoring module, an early warning module and a supervision module; and a slope offset threshold is set according to information of a slope, and configured to determine whether positions of the monitoring points are located in a normal area, and under the condition that a slope offset exceeds the threshold, it is indicated that the monitoring points cannot properly monitor the slope area, and need to be rearranged according to an offset direction.
