Embodiment Construction

[0015] The built-in programmed electronic theodolite angle gauge automatic three-dimensional tree measurement method is different from the existing methods, and has been greatly improved, specifically:

[0016] The electronic theodolite is used as a tool to collect the data of individual trees and stand factors, and the data is stored and processed by PDA (Personal Digital Assistant), thus realizing the automatic collection and processing of forest information.

[0017] The determination method of single wood is as follows:

[0018] (1) Measurement of tree height and arbitrary section height: as shown in Figure 1, when carrying out tree height measurement, determine a fixed height at the base of the trunk with a measuring tape earlier, usually this height is determined as 1.3 meters, i.e. chest height. Then place the instrument at a position where you can see the treetops and the chest height at the same time. After the instrument is leveled, observe the chest height and any s...

Abstract

The invention discloses the automatic stereoscopic forest measuring technology of an inner-arranged programmable electronic theodolite angle gauge, uses the electronic theodolite as a tool to collect all factor data of an individual tree and a forest, a PDA (Personal Digital Assistant) stores and processes the data, the electronic theodolite and a forest compass naonori to observe directly a treetop and a tree base of a tree, and uses a vertical point sampling method to test the even height of the forest, thus realizing the real time, automation and accurate testing of the even height of the forest; compared with the original method, the method saves time, reduces the working load and improves the working efficiency; the storage and processing of the data is realized by the PDA programming program to greatly improve the automation degree of the work.

Description

1. Technical field [0001] The invention relates to an automatic tree measuring technology, in particular to an automatic three-dimensional tree measuring technology with a built-in program type electronic theodolite angle gauge. 2. Technical Background [0002] The classic forest monitoring technology is backward. It is based on manual operations such as mechanical pointer compass positioning measurement and aerial photo interpretation. It has a long cycle, low efficiency, and poor accuracy, and is far from meeting the monitoring needs of forest resources and ecological environment. Domestic forest monitoring is limited to the macroscopic and extensive stage with remote sensing and conventional ground survey as the main technology. The precise measurement of some indicators, such as tree height, the diameter of any tree trunk, etc., is far from being resolved to a satisfactory level. [0003] The present invention collects single tree and forest stand various monitoring fac...
