A Review of LIDAR Radiometric Processing: From Ad Hoc Intensity Correction to Rigorous Radiometric Calibration

In addition to precise 3D coordinates, most light detection and ranging (LIDAR) systems also record "intensity", loosely defined as the strength of the backscattered echo for each measured point. To date, LIDAR intensity data have proven beneficial in a wide range of applications because they are related to surface parameters, such as reflectance. While numerous procedures have been introduced ...

Radiometric Calibration of Als Intensity

We have developed a new concept of empirical calibration scheme for airborne laser scanner (ALS) intensity by means of portable brightness calibration targets, which can be laid out in the flight target area. The accurate radiometric calibration of these targets is based on laboratory measurements with CCD-based laser backscatter instrument and terrestrial laser scanner reference measurements i...

Temperature Compensation for Radiometric Correction of Terrestrial LiDAR Intensity Data

Correction of terrestrial Light Detection and Ranging (LiDAR) intensity data has been increasingly studied in recent years. The purpose is to obtain additional insight into the scanned environment that is not available from the geometric information alone. Radiometric correction, as the name implies, corrects the received intensity to standard reflectance values in the range of (0, 1). This cor...

Radiometric Calibration of a Dual-Wavelength, Full-Waveform Terrestrial Lidar

Radiometric calibration of the Dual-Wavelength Echidna(®) Lidar (DWEL), a full-waveform terrestrial laser scanner with two simultaneously-pulsing infrared lasers at 1064 nm and 1548 nm, provides accurate dual-wavelength apparent reflectance (ρ(app)), a physically-defined value that is related to the radiative and structural characteristics of scanned targets and independent of range and instrum...

Radiometric Calibration of Airborne Lidar Intensity Data for Land Cover Classification

The rapid development of the airborne LiDAR systems paves the way for the use of the LiDAR technology in different bathymetric and topographic applications. LiDAR has been used effectively for digital terrain/surface modelling by measuring the range from the sensor to the earth surface. Information can be extracted on the geometry of the scanned features (e.g. buildings, roads) or surfaces elev...
