Region delineation method and system

Abstract

An embodiment of the invention provides a region delineation method and system. The method comprises steps as follows: acquiring a to-be-analyzed image of a study region, and pre-processing the to-be-analyzed image; establishing an analysis document, and analyzing the pre-processed to-be-analyzed image according to the analysis document to mark element points in the to-be-analyzed image; establishing an evaluation index, and obtaining evaluation results of blocks contained in the to-be-analyzed image according to the evaluation index and mark results of the element points in the to-be-analyzedimage; performing region delineation according to the evaluation results of the blocks in the to-be-analyzed image; generating corresponding databases and data tables according to image information of the blocks contained in the delineated region. According to the region delineation method, the region meeting the need is obtained by adopting modes of element point mark, element point evaluation and block evaluation, and compared with traditional survey methods, the method has advantages that the processing is more convenient and the result is more reliable.

Description

technical field [0001] The present invention relates to the technical field of hydrogeology, in particular to a method and system for delineating an area. Background technique [0002] Traditional groundwater survey methods mainly include: using hydrogeological survey materials to find water, geophysical prospecting to find water, drilling to find water, etc. The traditional method is not only time-consuming and labor-intensive, but also cannot realize large-scale dynamic monitoring and evaluation due to the lack of control points and poor representation. In addition, the particularity of natural conditions in some outdoor environments, such as plateau hypoxia, harsh environment, inaccessible, and difficult field work Large, etc., leading to the traditional groundwater investigation method can not meet the needs of hydrogeological investigation. Contents of the invention [0003] In view of this, the object of the present invention is to provide an area delineation method...
