摘要
研究了机载雷达技术在植被实物指标调查中的应用方法及效果,并以广东省河源市SU地块土地开发项目为例,分析了如何通过合理选择设备、优化测绘路径、筛分激光点云、修正模型点云等方法,使激光点云模型呈现更高精度。从而为植物实物指标调查工作夯实可靠的数据基础,并大幅提高工作效率,为国土空间规划后续工作开展奠定坚实基础。
The purpose of this paper is to study the application method and effect of airborne LiDAR technology in vegetation physical index survey.Taking the land development project of SU plot in Heyuan of Guangdong province as an example,this paper analyzes how to make the laser point cloud models with higher accuracy through reasonable selection of equipment,optimization of mapping path,screening of laser point cloud,correction of model point cloud and other methods.It provides a reliable data basis for the investigation of vegetation physical indicators,greatly improves the work efficiency,and lays a solid foundation for the follow-up work of land spatial planning.
