摘　　要：以某采煤区为工程背景,结合采空区的实际地表情况,构建了适用于采空区建筑物地面三维激光扫描(Terrestrial Three-Dimensional Laser Scaning,TLS)监测方法,提取的坐标中误差均不超过5.8 mm,手动提取的坐标中误差最大为8.6 mm。研究结果说明,所提出方法的监测效果较好。这种监测方法主要可适用于立面墙体或部分采空区建筑物立面的变形监测,为TLS应用于采空区建筑物立面的变形监测提供新的可行性方案。Taking a certain coal mining area as the engineering background,combined with the actual surface con⁃ditions of the mining area,this article constructs a Three-dimensional Laser Scan(TLS)monitoring method suitable for buildings in goaf.The extracted coordinates have an error of no more than 5.8 mm,while the maximum error in manually extracted coordinates is 8.6 mm,The results indicate that the monitoring results of this method are bet⁃ter.This method is mainly applicable to monitoring the deformation of façade walls or some buildings in goaf,pro⁃viding a new feasible solution for TLS application in monitoring the deformation of façade buildings in goaf.
