Investigation of Airborne LIDAR Intensity Data

초록

LiDAR(Light Detection and Ranging) system can record intensity data as well as range data. Recently, LiDAR intensity data is widely used for landcover classification, ancillary data of feature extraction, vegetation species identification, and so on. The intensity return value is associated with several factor, so same features is not consistent for same flight or multiple flights. This paper investigated correlation between intensity and range. Once the effects of range was determined, the single flight line normalization and the multiple flight line normalization was performed by an empirical function that was derived from relationship between range and return intensity
