The invention belongs to the field of
natural resource management, and particularly discloses a land
resource management and utilization change information real-time acquisition method, device and equipment and a medium, and the method comprises the steps: S1, obtaining a
data stream from a first-class sensing source, and generating early warning data indicating that the surface state is abnormal; s2, on the basis of the early warning data, triggering collection of a second-class
data stream of the target area; s3, carrying out near real-time analysis on the second-class
data stream, and identifying whether a predefined dynamic target representing a
land development behavior exists in the second-class data
stream or not; s4, fusing the early warning data and the
behavior recognition result to generate structured
land utilization change
event data; according to the invention, wide-area and rapid preliminary screening is realized through abnormal state early warning; near-field and accurate video analysis and behavior capture are carried out in combination with triggering behavior evidence secondary confirmation, the overall timeliness of change
information discovery is improved, and meanwhile, the misjudgment rate is remarkably reduced in combination with state and behavior
cross validation.
