Analysis and correction of the dependency between laser scanner intensity values and range
Terrestrial laser scanning intensity range correction
2014/7/30
Intensity values, which are registered by a terrestrial laser scanner system (TLS) for each point of a 3D point cloud in addition to its coordinates, are affected by the characteristic of the measured...
THE EFFECTS OF LASER REFLECTION ANGLE ON RADIOMETRIC CORRECTION OF THE AIRBORNE LIDAR INTENSITY DATA
Radiometric Correction LiDAR Intensity Data Reflection Angle Surface Normal Land Cover Classification
