Extraction of individual tree attributes using ultra-high-density point clouds acquired by low-cost UAV-LiDAR in Eucalyptus plantations
Key message
In this paper, we first introduced a novel method for directly measuring tree diameters from UAV-LiDAR point clouds utilizing the χ2-filtering technique and a technique for measuring tree heights using pseudo-waveforms.
