为了解决高原地形复杂地区,作业环境恶劣导致的无人机载激光扫描(LiDAR)测绘作业安全风险大、效率低的实际问题,研究了在高原地区利用无人机载LiDAR技术开展大比例尺测图的关键技术流程和实施要点,提供了利用三维激光点云直接绘制地形图的可行方法,从而改进了高原区机载激光扫描数据采集方法,提高了激光点云在大比例尺测图中的利用效率,为高原地区风电场项目大比例尺地形图测绘提供了安全、高效、实用的作业方案,并通过具体工程实践验证了该方法的有效性。
High safety risks and low efficiency come with UAVlaser scanning(LiDAR)surveying and mapping due to complex plateau terrain and poor working environment.To solve the problems,we studied the key technical process and implementation points of large-scale mapping by using UAVLiDAR technology in plateau areasand provided a feasible method of directly drawing topographic map using 3D laser point cloud.Thus,we improved LiDAR data acquisition method in plateau areas and enhanced the utilization efficiency of laser point cloud in large-scale mapping,providing a safe,efficient and practical operation scheme for large-scale topographic mapping of wind farm projects in plateau areas.Finally,weverified the effectiveness of this method by specific engineering practice.
