摘　　要：为解决煤矿沉陷区由于其范围较小、地形复杂和人员通行困难等因素,致使全站仪内外业一体化数字成图或数字摄影测量方法因工期与成本原因,无法较好满足工作需求.采用三维激光扫描仪通过非接触测量极大的解决了通行问题,既保证成图精度要求,又提高了工作效率.将三维激光扫描技术与GPS技术相结合进行外业数据采集,通过点云处理,进行等高线、精细地形图绘制.研究结果表明:该方法可以满足大比例尺测图精度要求.Due to the smaller range,complex terrain and difficult accessibility of coal mine subsidence area,plus the tight deadline and cost factors,the integrated digital mapping with both total station and digital photogrammetry is unable to meet the project demand.The method of non-contact measurement and 3D laser scanner gives a solution to the accessibility problem,and it not only ensures the mapping accuracy,but also improves the work efficiency.3D laser scanning and GPS are adopted to collect field data,and then processes the point cloud,finally generates contour and fine topographic map.The study results show that this method of plotting can meet the accuracy requirements of large-scale mapping.
