¶ Calculating the volume of a single tree crown based on laser point cloud so forestry production & operation can be improved
Description: The invention discloses a foundation laser point cloud individual tree crown volume extraction method based on spherical coordinate integration, and belongs to the technical field of forestry engineering. The method comprises the following steps: firstly, extracting a crown point cloud by adopting a point cloud segmentation method of a visual optimal threshold selection strategy, and improving crown point extraction and operability; projecting a tree crown point from a three-dimensional point cloud space to a three-dimensional spherical coordinate space, and innovatively providing a new tree crown form fine description mode; and finally, the crown is cut into a plurality of rectangular pyramid-shaped infinitesimal bodies, and integral is carried out to realize crown volume extraction, so that the extraction precision and universality are improved. According to the method, a complete technical process for extracting the volume of the single tree crown based on the foundation laser point cloud is provided, so that the automation and intelligence level of forestry production and operation can be improved; the method has important theoretical significance and engineering application reference value for forestry scientific research such as forest three-dimensional shape simulation, forest resource investigation and overground biomass estimation and forestry production.
