探地雷达识别树木内部缺陷层位技术的研究

Research on Internal Defect Layer Identification of Trees Using Ground Penetrating Radar

对树木内部缺陷(腐朽、空洞)识别分层技术进行了深入研究,并以柳树为研究对象,运用探地雷达对树木内部的缺陷进行探测,通过阈值法分析树木内部的缺陷并对其进行识别分层。该方法对树木内部缺陷的识别分层误差率可控制在20%以内,这项技术对古树名木的保护有非常重要的意义和广阔的应用前景。

In-depth study on the internal defects（ decays,holes） layered identification technology is conducted,with willow as the research object,a ground penetrating radar（ GPR） is used to detect the defects inside the tree,with a threshold method to analyze the defects inside the tree and conduct layered identification. This method can control internal defect layered identification errors within 20% and this technology is of great importance for the protection of ancient trees and has broad application prospects.
