摘要: 矿区井工开采时地表沉陷导致的路面裂缝是井工开采常见的损害之一。首先根据地面三维激光扫描仪数据获取方式将扫描数据按扫描线进行分解,再利用小波变换对信号突变点的良好检测功能,对矿区沉陷区域内扫描数据中各扫描线包含的路面裂缝信息进行提取,实现了良好的检测效果。

Abstract: The pavement cracks resulted from the surface subsidence in underground mining is one of the common damages to underground mining.First of all,according to the data acquisition mode by the terrestrial 3D laser scanner,the scan data is decomposed based on the scan lines,and pavement cracks information contained in each scan line is obtained by using wavelet transform with good detection function on signal mutations,which realizes good detection effect.

Key words: Mining area, Pavement crack, Point cloud, Wavelet transform
