Abstract
The paper deals with the calibration of cloud point by a terrestrial laser scanner using terrestrial spectrometry. Specifically, the purpose of the exercise is to calibrate the cloud point reflectivity at 432nm.
The spectrometry will be used to generate spectral signatures to identify nine (9) different colour gradations in the first stage and in the second stage, for the reflectivity calibration received by the scanner at different angles. The measurements were taken at the remote sensing laboratory with SVC HR-1024 and EXCEL software were used to process them.
In an outdoor environment, the Leica C10 Laser terrestrial scanner was used to observe the intensity difference of the radiation according to the angle of incidence. The CYCLONE program was used to transfer the measurements to the EXCEL software where the measurements were further processed for the final results
Finally, a comparison of the spectral signatures follows, discussion of radiation intensity results, and a report of the conclusions for each case.
