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...
متن کاملRadiometric calibration of a dual-wavelength terrestrial laser scanner using neural networks
The Salford Advanced Laser Canopy Analyser (SALCA) is a unique dual-wavelength full-waveform terrestrial laser scanner (TLS) designed to measure forest canopies. This article has two principle objectives, first to present the detailed analysis of the radiometric properties of the SALCA instrument, and second, to propose a novel method to calibrate the recorded intensity to apparent reflectance ...
متن کاملRadiometric Calibration of Full-waveform Small-footprint Airborne Laser Scanners
Small-footprint airborne laser scanners (ALS) are lidar instruments originally developed for topographic mapping. In recent years ALS sensors are increasingly used also in other applications (forest mapping, building extraction, power line modelling, etc.) and their technical capabilities are steadily improving. While the first ALS systems only allowed determining the range from the sensor to t...
متن کاملCalibration of a Terrestrial Full Waveform Laser Scanner
Recent advances in Light Detection And Ranging (LiDAR) enable digital acquisition and storage of the entire waveform of backscattered laser pulse energy. Pre-requisites for extracting target radiometric and geometric properties via waveform analysis include defining a model for accurately determining peaks in the return energy waveform and a method for transforming waveform peak amplitudes to a...
متن کاملRadiometric Calibration of Full-waveform Airborne Laser Scanning Data Based on Natural Surfaces
Airborne laser scanning (ALS) has become a commercially available and therefore widely used technique for obtaining the geometric structure of the earth’s surface. For many ALS applications it is beneficial or even essential to classify the 3D point cloud into different categories (e.g. ground, vegetation, building). So far, most classification techniques use the geometry of the 3D point cloud ...
