基于多分辨率分析的LiDAR数据处理与可视化

LiDAR data processing and visualization based on mult-resolution analysis

基于多分辨率分析的数据滤波算法对于地形变化单一但地物和地形区别明显的场景,地形多变但连续且地物和地形区别明显的场景具有非常优越的滤波效果。研究基于多分辨率分析的数据滤波算法的基本原理,在VisualC++6.0平台上编程实现该算法,建立LiDAR数据处理与可视化系统,详细介绍各功能模块的实现方法和功能,实现由LiDAR系统获取的原始数据到最终的DEM生成的整个功能,一定程度上满足了实际的应用需求。

Data filtering algorithm based on multi-resolution analyses obtains a good result,especially for the scene in which terrain is flat while objects are distingushed obviously and the scene in which the terrain is diverse and obviously different from the objects.We researched basic principle of data filtering method based on multi-resolution analysis.The algorithm was carried out on Visual C＋＋6.0 platform,set up LiDAR data and visulization system.The article introduced the methods and functions of each module.It realizes the whole function from original data obtained by LiDAR system to final DEM generation.To some extent,it meets the needs of practical applications.
