摘要
南京市行道树普查和行道树险树危树调查项目对南京市34条道路两侧的行道树进行空间定位、行道树属性信息采集并利用无损探测技术对险树危树进行树干检测、后期动态监测,以生成行道树健康报告。通过阐述声呐探测仪PiCUS Sonic Tomograph的空洞探测算法、操作流程和二维三维成果示意图,表明其在行道树空洞探测方面的卓越表现。
The census of Nanjing street side trees and the investigation projects of dangerous trees is carried out to get street trees space location information and attribute information on both sides of the 34 roads in Nanjing. It uses non-destructive technique to detect trunks of dangerous trees and monitor them dynamically in the late to generate health reports of street trees. The hole detection algorithms,operation flow and the two-dimensional or three-dimensional results sketch of the sonar detector PiCUS Sonic Tomograph are presented to demonstrate its excellent performance in street trees' hollow detection.
