A Review of LIDAR Radiometric Processing: From Ad Hoc Intensity Correction to Rigorous Radiometric Calibration (2015, background): “Many of the photodetectors used in commercial topographic LIDAR systems are designed to be linear, meaning that the output photocurrent is linearly proportional to the input optical power over the detector’s operating range [1].”
Heritage Recording and 3D Modeling with Photogrammetry and 3D Scanning (2011, background): “Optical range sensors [29-31] like pulsed (Time-of-Flight), phase-shift and triangulation-based (light sheet or pattern projection) instruments have received much attention in recent years, also from non-experts, for 3D surveying and modeling purposes.”
A Comprehensive Automated 3D Approach for Building Extraction, Reconstruction, and Regularization from Airborne Laser Scanning Point Clouds (2008, methodology): “A Digital Surface Model (DSM) derived from point clouds acquired by Airborne Laser Scanning (ALS) [5] or stereo-photogrammetry [6, 7] already represents buildings.”
Advances in fusion of optical imagery and LiDAR point cloud applied to photogrammetry and remote sensing (2017, background): “…(Fernandez-Diaz et al. 2014), and each point has its XYZ coordinates and some optional attributes, such as time, flight line, intensity, colour, etc. LiDAR point cloud has conquered a major position ever since point cloud has become a mapping data product in its own right (Shan and Toth 2008).”
