Abstract

The invention relates to a forest resource monitoring method and device based on a laser radar and a storage medium. The method comprises the steps: carrying out feature variable extraction according to laser point cloud data, and obtaining sample plot feature variable data and global feature variable data; according to the sample plot feature variable data and the ground survey sample plot, establishing a laser radar accumulation estimation model; analyzing the global feature variable data through forest resource management data to obtain a tree species (group) set; inputting the tree species (group) set into the laser radar forest stand volume estimation model for calculation to obtain global forest stand volume estimation information, and deducing the global forest stand volume estimation information to obtain a tree measurement factor set; and updating the forest stock and tree measurement factor information to forest resource management vector data, and managing forest resources by a development information management system based on the Internet+ technology. According to the invention, the precision and timeliness of forest stock monitoring can be improved, and annual output of forest resources is realized.

Description

technical field [0001] This application relates to the technical field of resource monitoring, in particular to methods, devices and storage media for forest resource monitoring based on laser radar. Background technique [0002] my country's forest resource monitoring system includes two levels of national monitoring and local monitoring. In a narrow sense, these two levels are mainly composed of the continuous inventory of the first-class forest resources and the planning and design survey of the second-class forest resources. However, due to the relatively independent operation of these two systems, it is difficult to connect the two. Objectively, there are two sets of data on forest resources, and the monitoring period is too long to achieve annual output. Forest Chief System" and other information requirements for forest resources management annual performance appraisal and evaluation. In a broad sense, the monitoring system also includes the monitoring of changes in ...
