Spectral Pattern Classification in Lidar Data for Rock Identification in Outcrops
Figure 7
Edge effect in the targets, using the Ilris 3D divergence (2,2 cm at 100 m) and 1 cm space between the points. (a) The laser pulse in full incidence on the target. (b) The laser pulse with almost 50% incidence on the target, obtaining a second response from part of the pulse outside the target. (c) The laser pulse with only 10% of incidence in the target, obtaining an extremely low intensity primary point and a stronger second response.
