Abstract
Description
technical field
[0001] The invention relates to geological remote sensing interpretation technology, in particular to a method for extracting fault structure information by using image processing and prior knowledge. Background technique
[0002] The line positions of long lines such as railways, highways, and water conservancy, large-scale station buildings, and auxiliary facilities should avoid or pass through fault structures at a large angle, especially regional active fault structures, so as to improve the safety of the project. Fault structure has become the key content of engineering geological survey of Changchang Railway.
[0003] In recent years, artificial interpretation methods based on remote sensing information have emerged to extract fault structure information. However, this method mainly relies on manual visual interpretation, and there are still some problems: on the one hand, it is greatly affected by the experience and subjective factors of the judges; o...
