Abstract

The invention discloses a laser radar technology-based method for acquiring the forest growing stock in the high-canopy-density area. According to the technical scheme of the method in the invention, the ground information of an acquired high-canopy-density forest area is subjected to the detection of seed points firstly. Secondly, each single tree is extracted through the tree segmentation process. Finally, the forest growing stock in the high-canopy-density forest area is acquired by utilizing a DBH (diameter at breast height) - tree height - crown diameter model. The method flow, from the collection of data to the acquisition of the forest growing stock, is proposed based on the airborne laser radar technology. Therefore, the method provides a technical solution scheme for the forestry surveying applications of airborne laser radars in the high-canopy-density area. Meanwhile, the method provides a high-efficiency and low-cost technical support for the checking of forest resources.

Description

technical field [0001] The invention relates to a method for obtaining forest volume with very high canopy density based on laser radar technology, and belongs to the technical field of laser radar point cloud data processing. Background technique [0002] The main purpose of forest resource inventory is to conduct forest management and decision-making analysis (including applications such as deforestation and planting) by investigating the distribution and quality changes of various forest resources. The traditional method is to manually conduct a large number of on-site surveys on standard sample plots, and use parameters such as the diameter at breast height, canopy diameter, and tree height of a single tree in the sample data to estimate the stand information of the entire forest, which consumes a lot of human resources and time. In addition, the tree height is generally determined by visual experience during field measurement, and there are certain errors in its value. ...
