The present application relates to the technical field of disaster detection, in particular to a geological disaster detection method and system based on image processing, comprising the following steps: collecting multi-temporal topographic images and dividing them into blocks, constructing a main boundary angle difference value array, calculating the included angle change to screen image blocks and combining fault regions, extracting crack contours to calculate the opening angle and construct the offset sequence, generating an enhanced feature map based on gradient projection texture field interpolation, constructing a residual data field to divide grid points, and determining abnormal regions. In the present application, the main boundary angle difference value array of the blocks is constructed and affine aggregation is performed in combination with the consistency of the edge gray gradient, so that the precise reconstruction and continuity recovery of the cross-scale nonlinear fault structure in the topographic image are realized, the gradient derivative quantity is generated by using the crack endpoint opening angle offset sequence and the texture vector field is expanded, which can sensitively capture the weak morphological changes of the local topography in the time evolution process, and solve the problem that the small disaster precursor features are difficult to identify in a complex background.

This invention discloses a method for creating a micro-paleomorphic map of stratigraphy using a combination of well and seismic data, comprising the following steps: S11 Obtaining stratigraphic marker layers for correlation using drilling data within the area; S12 Comprehensive drilling calibration, conducting isochronous surface tracing and interpretation of seismic sequences, and establishing an isochronous stratigraphic framework using a combination of well and seismic data; S13 Reconstructing the pre-depositional paleomorphic features of the target layer using layer flattening technology; S14 Selecting a layer segment, calculating the stratigraphic thickness using the top and bottom data of the target layer, and obtaining the true seismic stratigraphic thickness after drilling correction; S15 Compacting and correcting the true seismic stratigraphic thickness to obtain the original sedimentary thickness of the stratigraphy; S16 Applying the original sedimentary thickness of the stratigraphy to generate a micro-paleomorphic map using Surfer mapping software. This invention is applicable to the field of petroleum exploration technology, is highly operable, and makes full use of well and seismic data for three-dimensional exploration areas with fewer wells. The micro-paleomorphic features reconstructed by this method can finely depict the paleotopographic features of the beach bar sandstone deposition period and analyze the planar distribution pattern of the beach bar sandstone.
