A novel method for 2-D agricultural soil roughness characterization based on a laser scanning technique
IEEE International Geoscience and Remote Sensing Symposium, 6-11 July 2008, Boston, MA, USA. IGARSS 2008.
In this paper we present a laser profiler, whose main aim is the determination of agricultural soil roughness. Its working principle is based on the acquisition of an image of anobject illuminated by a laser beam and on the use of 3D computer vision techniques to obtain the reconstruction of the scanned object. One of the most important purposes ofthis device is the attainment of the soil RMS height (s) and the correlation length (l) related to the autocorrelation function. These are fundamental inputs to derive soil moisture maps from soil backscattering data.
