Development of Three-Dimensional Detection System for Narrow and Hidden Underground Cavities

为解决工程建设难以获取狭窄及隐蔽地下空洞精确数据的问题,提出一套地下空洞三维探测系统。该系统以低成本的二维激光雷达为硬件基础,结合自主研发的数据采集装置,采用Data Conversion and Visualization软件进行数据坐标转换、通用三维格式转换及三维数据显示等操作,并对模拟的地下空洞进行可行性实验和精度分析。实验结果表明,该系统能高效获取高精度的地下空洞三维数据,硬件成本较低。为国内地下空洞探测工作提供了一种新的解决方法。

In order to solve the problem that it is difficult to obtain accurate data of narrow and hidden underground cavities in engineering construction,a set of three-dimensional underground cavity detection system is proposed. The system is based on the low-cost two-dimensional lidar,combined with the independently developed data acquisition device,and uses data conversion and visualization software to perform data coordinate conversion,general three-dimensional format conversion,three-dimensional data display and other operations,and carries out feasibility experiments and accuracy analysis on the simulated underground cavity. The experimental results show that the system can efficiently obtain high-precision 3D data of underground cavities,and the hardware cost is low,which provides a new solution for the domestic underground cavity detection work.
