摘　　要：广州火炉山隧道工程南北连接华观路和广汕公路,项目测图区域内包括起伏的山地和密集的村庄,涉及的地形和地貌复杂。本文在大比例尺地形图测量中将无人机倾斜航空摄影测量、机载LiDAR测量和地面三维激光扫描技术相结合,形成了空地协同的测绘模式,极大地缩短了外业工作时间,有效提高了外业采集效率,成果经过检核完整可靠。The Guangzhou Huolu Moutain tunnel project connects Huaguan Road and Guangshan Highway from north to south. The project mapping area includes rolling hills and dense villages, which involve complex terrain and landforms. This paper introduces the combination of UAV tilt aerial photogrammetry, airborne LiDAR survey and ground three-dimensional laser scanning technology in the large-scale topographic survey, forming a space-ground coordinated surveying and mapping mode, which greatly reduces field work time and effectively improves the field data collection. The obtained results are complete and reliable after inspection.
