Identifying individual trees and delineating their canopy structures from the forest point cloud data acquired by an airborne LiDAR (Light Detection And Ranging) has significant implications in forestry inventory. Once accurately identified, tree structural attributes such as tree height, crown diameter, canopy based height and diameter at breast height can be derived. This paper focuses on a n...

In the paper is proposed an original calibration method for microcalorimeter measurements on thermistor power sensors and certain preliminary experiments are illustrated, which are necessary for the effective application of the method. This new method avoids some critical steps in the usual microcalorimeter calibration, saves the time and does not require vectorial measurements for the feeding ...

A calibration target can be imaged to provide correspondences between points in the image and points in space. It is, however, generally impractical to position the calibration target accurately with respect to the camera coordinate system using only mechanical means. As a result, the relationship between the target coordinate systemand the camera coordinate system typically also needs to be re...
