Study on Automation Technology and Method of Forest Measurement in Fixed Sample based on Total Station and PDA

摘要

In modern forest measurement situation that lack of good accuracy, in order to meet the needs of precision forestry and realize the precise measurement of every single tree, this paper introduces an automate technology and software platform of forest measurement in fixed sample. This technology and method can give full play to the precision total station angle measurement range function and PDA data processing and storage function, which are based on the communication system programming development of total station and PDA with WinCE. This automation technology are used to gain 3d coordinate, tree height, DBH and crown of trunks, it can both realize the automation process of testing trees and ensure the accuracy of measurement, improving the work efficiency greatly.
