A Denoising Method for LiDAR Full-Waveform Data [PDF]

open access: yesMathematical Problems in Engineering, 2015
Decomposition of LiDAR full-waveform data can not only enhance the density and positioning accuracy of a point cloud, but also provide other useful parameters, such as pulse width, peak amplitude, and peak position which are important information for subsequent processing. Full-waveform data usually contain some random noises.
