The Deciduous Tree Crown Segmentation Challenge

  Deciduous tree crown segmentation is widely recognized as a particularly challenging task. While various approaches for conifer crown delineation have proven successful, their transferability to deciduous forest stands remains limited. Accurate crown segmentation constitutes a critical prerequisite for assessing the vitality of individual deciduous trees based on spectral or structural metrics. In particular, in dense deciduous stands characterized by...

DJIs new UAV Lidar System – the L3

DJI has recently announced the release of its new UAV LiDAR system — the DJI Zenmuse L3. For those engaged in UAV-based LiDAR research and applications, this long-anticipated successor to the L2 represents a significant technological advancement. The cost of professional-grade airborne LiDAR systems with high-accuracy capabilities has remained relatively stable over the past years. For example, some of the...
