Examining the possibility of correcting imagery acquired for the purpose of obtaining spectral reflectance coefficients in the infrared range using photometric measurements

Abstract

Commission VI, WG VI/4KEY WORDS: Remote Sensing, Measurement, Calibration, Multispectral, Experiment, ABSTRACT:The purpose of this paper is to determine the possibility of using photometric measurements in order to correct imagery acquired in the 900-1700nm range. This imagery is acquired for the purpose of acquiring spectral reflectance coefficients in variable lighting conditions. This paper will present a series of experiments, the problems encountered and obtained results. The main aim of this research was to determine a link between these two quantities (luminance and irradiance) in order to be able to eliminate the need of using such a spectroradiometer (a large, heavy and costly instrument) when acquiring spectral reflectance data from a XEVA XS-1.7.320 camera mounted on an UAV without using a reference panel.
