Observation Selection, Total Variation, and L-Curve Methods for LiDAR Data Denoising

Figure 6

The denoising results by the proposed method and the HKO method . (a) The LiDAR data were collected on 4 March 2015 from 21 : 26 : 16 to 21 : 46 : 39 with a fixed azimuth angle and the denoising results. (b) The SNR values of the LiDAR data in the 1st row. (c) The LiDAR data were collected on 5 March 2015 from 04 : 16 : 02 to 04 : 16 : 25 with a fixed azimuth angle and the denoising results. (d) The SNR values of the LiDAR data in the 3rd row.
