The Influence of Spatial Calibrations of Hyperspectral Line Scanners on the Accuracy of Geocoding of Hyperspectral Cube
Although calibration during geocoding process shows drastic improvements in achieved geocoding accuracy, the internal orientation error remains. In order to properly determine these errors, we must first of all know the mathematical model of mapping of the line sensor. The mathematical model of mapping of the line sensor has been expanded to account for the distortion of the lens in order to eliminate all systematic errors induced by displacement of the real sensor mapping plane from the ideal mathematical model of the central projection. After a mathematical model was established, a calibration of the hyperspectral scanner was performed in the laboratory, observing test samples from 5 different recording sites. Calibration elements are determined by airborne beam equation (BBA method).
