Problems solved by technology

At present, the single tree identification using TLS technology is mainly concentrated on tall broad-leaved trees, and the single tree identification is mostly carried out on the basis of diameter fitting. Using the center of the fitted two-dimensional curve as the single tree position, that is, the number of diameters that can be fitted It determines the accuracy of single wood detection, and there are relatively few studies on moso bamboo

Abstract

The invention discloses a moso bamboo forest number identification method and device based on a foundation laser radar. The method comprises the following steps: obtaining foundation laser radar point cloud data of a moso bamboo forest through the foundation laser radar; obtaining a point cloud data file according to the ground-based laser radar point cloud data; intercepting the point cloud data file according to a preset interception upper limit and an interception lower limit, and generating a section of horizontal strip only containing bamboo stalks; carrying out voxelization on the horizontal strip in a three-dimensional space to generate a voxel space, wherein the voxel space comprises voxels of the ground-based laser radar point cloud data; and taking the continuous voxel group in the vertical direction of the whole horizontal strip as a stem, and traversing the voxel space to obtain the number of the moso bamboo forest. By adopting the embodiment of the invention, not only can the field workload of sample plot investigation be reduced, but also according to the special morphological characteristics of the moso bamboos, the proposed new method can improve the identification rate of the single moso bamboos and provide reference for bamboo forest investigation.

Description

technical field [0001] The invention relates to the technical field of forest resource monitoring, in particular to a method and device for identifying the number of moso bamboo forests based on ground-based laser radar. Background technique [0002] Bamboo forest is an important part of my country's forest resources, has excellent carbon sequestration capacity, and plays an important role in promoting industrial and regional economic development. Therefore, it is very important to conduct regular surveys of bamboo forest resources to grasp its current status and growth changes. The traditional survey of bamboo forest resources is time-consuming, laborious and expensive. As an active remote sensing technology, ground-based lidar can directly, quickly and accurately obtain the three-dimensional geographic coordinates of the research object, and provide accurate information about tree location, number of trees, diameter at breast height, and forest structure parameters of tre...
