Title:
EXTRACTION SYSTEM OF SLOPE COLLAPSE SPOT, EXTRACTION METHOD OF SLOPE COLLAPSE SPOT AND EXTRACTION PROGRAM OF SLOPE COLLAPSE SPOT
Document Type and Number:
Japanese Patent JP2023140677
Kind Code:
A
Abstract:
To provide an extraction system of a slope collapse spot which can extract a collapse spot of a slope at a low cost while enhancing extraction accuracy.SOLUTION: An extraction system of a slope collapse spot comprises: an acquisition unit which is configured to acquire a visible light image of a collapse extraction region on a ground surface and a vegetation index map indicating the distribution of a vegetation index in the collapse extraction region; and an extraction unit which is configured to execute detection processing of detecting a low index region in which the vegetation index is smaller than a threshold in the vegetation index map from the collapse extraction region, and extraction processing of extracting a collapse spot of a slope with pattern matching to a determination object region including the low index region in the visible light image.SELECTED DRAWING: Figure 2
