摘要:

机载激光雷达是一种快速获取高精度三维地理数据的新技术,对它所获取的点云数据的滤波过程就是将LIDAR点云数据中的地面点和非地面点分离的过程。主要对数学形态学的滤波算法、基于坡度的滤波法、基于TIN的LIDAR点云过滤算法、基于伪扫描线的滤波算法、基于多分辨率方向预测的LIDAR点云滤波方法等几种较为重要且实用的激光雷达点云数据滤波算法进行介绍和讨论,评价对比了各自算法的优势和不足,初步探讨了每种算法缺陷及其改进方向。

关键词: 激光雷达点云数据滤波算法    
Abstract:

Airborne LIDAR is a new technology that can obtain high\|precision three-dimensional geographical data quickly.Filtering process for LIDAR points cloud data is to separate the non\|ground points from the ground points.Several important useful filtering algorithms for LIDAR points cloud data\|\|mathematical morphology based filtering algorithm,slope based filtering algorithm,TIN based filtering algorithm,pseudo scanning lines based filtering algorithm,etc.have been introduced,discussed and contrasted.their advantages and disadvantages,the improving advice to each filtering algorithms also have been presented in the paper.
