摘要
机载激光雷达技术是测绘中一项非常重要的技术,其可高效率地获取高密度点云,在相关测绘领域具有很大的发展潜力。以杭州师范大学仓前校区作为研究区,利用M300 RTK无人机搭载L1激光雷达采集研究区的激光点云数据,通过数据处理制作大比例尺数字高程模型,介绍基于激光点云数据的数字高程模型的制作方法和精度评价方法,分析了方法的合理性、有效性。
Airborne laser radar technology is a very important technology in surveying and mapping.It can efficiently obtain high-density point clouds,and has great development potential in related surveying and mapping fields.Taking the Cangqian campus of Hangzhou Normal University as the research area,the M300 RTK UAV is used to carry L1 lidar to collect the laser point cloud data in the research area,and a large-scale digital elevation model is produced through data processing.The manufacturing method and precision evaluation method of the digital elevation model based on the laser point cloud data are introduced,and the rationality and effectiveness of the method are analyzed.
