Title:
GEOLOGICAL LINEAR BODY EXTRACTION METHOD BASED ON TENSOR VOTING COUPLED WITH HOUGH TRANSFORM
Document Type and Number:
WIPO Patent Application WO/2019/153746
Kind Code:
A1
Abstract:
The present invention provides geological linear body extraction method based on tensor voting coupled with Hough transform, comprising the following steps: pre-processing a remote sensing image, so as to obtain a pre-processed remote sensing image; selecting three optimal wavebands from N multi-spectral wavebands of the pre-processed remote sensing image, so as to obtain a remote sensing image combined by the optimal wavebands, N being a natural number greater than or equal to 3; using Gaussian high-pass filtering to perform sharpening processing on the remote sensing image combined by the optimal wavebands, so as to enhance linearized edge information; performing edge detection on the remote sensing image having enhanced linearized edge information, so as to obtain all edge points in the remote sensing image; and converting all edge points in the remote sensing image from an image coordinate system to a parameter coordinate system, and extracting a geological linear body from the parameter coordinate system. The present invention relies less on the knowledge and experience of interpretation experts, shortening the time of processing, saving a vast amount of manpower, having a stronger practical value and a promotion meaning.
