The invention provides a method of fitting, comparing and extracting buried pipeline attributes through a ground-penetrating radar result. The method comprises the following steps of combining different pipeline attributes and forming an attribute combination table possessing a plurality of attribute combinations; for the different attribute combinations, through a GPRMax tool, carrying out forward modeling and acquiring the forward modeling results of the attribute combinations; collecting the time of the forward simulation results of the attribute combinations and amplitude combination curves and establishing a forward modeling wave spectrum characteristic database, hitching with the attribute combinations and forming a ground-penetrating radar pipeline detection wave field characteristic database; through a curve fitting algorithm, carrying out curve fitting on the time and the amplitude combination data of actual-measurement ground-penetrating radar data and the time and the amplitude combination curves in the wave field characteristic database; and displaying the simulation result of a curve possessing highest fitting similarity. In the invention, the attribute acquired afterfitting is displayed as a character mode so that a non-professional person can conveniently acquire the information of ground-penetrating radar professional data.
Description
technical field [0001] The invention relates to the field of geophysical detection and the field of computer application technology, in particular to a method for extracting attributes of buried pipelines through ground-penetrating radar results fitting and comparison. Background technique [0002] At present, the detection technology for metal pipeline detection has become mature, but the detection of non-metallic pipelines and deep-buried pipelines is still a technical problem, because non-metallic pipelines are neither conductive nor magnetic, and are basically insulated. Commonly used metal pipeline detectors cannot Its detection has brought great difficulties to determine the location and buried depth of underground non-metallic pipelines, avoid damage caused by construction excavation, and manage and maintain the safety of pipeline networks. How to detect non-metallic pipelines quickly, accurately and conveniently has become an urgent problem to be solved. Because the...
