Abstract: [Objective] To obtain the upper crown structure parameters（crown vertex, tree height, crown width and upper crown length） and to simulate and visualize the outer upper crown profile of Cunninghamia lanceolata based on Unmanned Aerial Vehicle（UAV） LiDAR data in order to provide reference for recognizing the individual tree crown characteristics and tree species. [Method] By means of local maximum method in LiDAR360 software, the Pit-Free CHM（canopy height model）, which was generated from LiDAR po... More
