In the eld of forestry, for decades eld measurements have been done in order to estimate tree stem volumes from a certain area. This has been done to get information about the growth of forest in certain time periods. The estimation has been based on sample plots. In a plot, one diameter of a tree stem and its distance from the center of the plot have been measured. Until now the measurements have been made manually with a tape measure. In this paper the procedure to use video measurements for getting the required information will be presented. Co-ordinate system will be created on site and 3D stem volume models will be estimated based on video image measurements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
