The invention discloses a deformation monitoring and early warning method and system for early warning of slope disasters, and the system comprises a geological grid and mark layout module which is used for dividing grids with different densities according to the height and slope rock-soil layer data and a profile map, determining the three-dimensional coordinates of nodes, and embedding passive acoustic vibration marks; the unmanned aerial vehicle inspection planning module determines the number of unmanned aerial vehicles and generates a flight path and equipment parameters; the multi-modal data acquisition module controls the unmanned aerial vehicle to acquire sound vibration, three-dimensional point cloud and environmental data; the model training module constructs a physical constraint function and takes multi-modal data as an input / output theoretical physical quantity; and the early warning judgment module sets a matching degree interval, determines triggering conditions according to normal, attention and early warning intervals of historical data, starts encryption inspection by three times of attention, and triggers an alarm by single time of early warning. According to the invention, encrypted inspection or early warning can be timely started according to the matching degree interval and the trigger condition, and the accuracy and timeliness of slope safety monitoring are effectively guaranteed.
