摘　　要：天星水库区域处于植被茂密、通视条件差、河道弯曲地带,采用传统测量方式,如利用无人机搭载相机的航空摄影测量方式无法满足库区大比例尺地形图精度要求,而先进的无人机机载激光雷达测量技术,在高精度三维空间信息实时获取方面取得重大突破,水库困难地区测图中无人机机载激光雷达技术得到了具体应用且效果良好。Tianxing Reservoir is located in a zone with dense vegetation,poor visibility and meandering rivers.Traditional surveying methods such as camera-mounted Unmanned Aerial Vehicle(UAV)can't meet the accuracy requirements of large-scale topographic map in the reservoir area.The advanced UAV airborne LiDAR measurement technology has made a great breakthrough in real-time acquisition of high-precision three-dimensional spatial information.The UAV-borne LiDAR technology has been specifically applied in the mapping of difficult areas of reservoirs and has achieved good results.
