Abstract
A computer system creates and stores a library of LiDAR models for standard trees that have measured characteristics. A point cloud of LiDAR data from an unidentified tree in a forest is compared against a point cloud defined by a LiDAR model of a standard tree in the library to find a match. If a match is found, one or more characteristics of the matching standard tree are associated with the unidentified tree.
Claims16
A computer system, comprising:
- a processor that is configured to execute a sequence of programmed instructions that cause the processor to:
- read LiDAR data obtained from unidentified trees in a forest;
- select a LiDAR point cloud for an unidentified tree in the forest;
- compare the selected LiDAR point cloud for the unidentified tree to a point cloud defined in a library of LiDAR models for a number of standard trees;
- determine if the LiDAR point cloud for the unidentified tree matches a point cloud defined by a LiDAR model for a standard tree, and if so to associate one or more characteristics stored in the LiDAR model for the standard tree with the unidentified tree.
A computer readable storage media that has stored thereon a library of LiDAR models associated with standard trees, wherein the LiDAR model for each standard tree defines a point cloud of LiDAR data points and one or more characteristics for each standard tree.
A computer system that is accessible by one or more remote computers, the computer system including a computer readable storage media that has stored thereon a library of LiDAR models associated with standard trees, wherein LiDAR models for each standard tree define a point cloud of LiDAR data points and one or more characteristics for each standard tree.
