摘　　要：机载激光雷达技术在测绘行业的应用越来越广泛。以机载激光雷达测量技术在本溪至集安高速公路项目中的应用为例,介绍了“单架次、单航带、局部平差分级、分阶段融合”的点云整体平差法,为解决大型机载LIDAR航测中众多点云数据精度不足问题提供了技术支持。Airborne lidar technology is more and more widely used in surveying and mapping industry.Taking the application of airborne lidar measurement technology in Benxi-Ji'an expressway project as an example,the point cloud overall adjustment method of"single sortie,single flight belt,local adjustment classification and phased integration"is introduced,so as to provide technical support for solving the problem of insufficient accuracy of many point cloud data in large airborne LIDAR aerial survey.
