Problems solved by technology

[0007] In order to overcome the many troubles that the existing tree height measurement method inevitably brings in the forest resource monitoring process and improve the observation accuracy and work efficiency, the purpose of the present invention is to provide a method for measuring the tree height with a total station instrument, which can be realized when the horizontal distance cannot be measured. The rapid and high-precision measurement of tree height under certain conditions overcomes the shortcomings of the existing technology

specific Embodiment approach

[0020] The method of measuring tree height with the total station is different from the existing method, and has been greatly improved, specifically: the angle is measured by the total station electronic speed measuring instrument, and the data is stored and processed in real time through the PDA, without the need to measure the total station to the center of the trunk The horizontal distance of the tree height can be measured by placing the total station twice on the same vertical plane and the three-dimensional forward intersection of the total station. At the same time, the precise angle measurement function of the total station electronic speed measuring instrument and the powerful PDA are fully utilized Data processing and storage functions, real-time collection and processing of field data. The specific implementation is as follows:

[0021] 1. In the complex terrain conditions of the forest area, if there are steep slopes or ravines in the survey area and the horizontal...

Abstract

The invention discloses a hypsometrical measurement method by using total station. Take total station to measure angle and PDA to real-timely save and manage data. Take allocating total station twice on the same vertical face and total station front converging method to realize real-time measuring of tree height without setting total station on horizontal distance of trunk center, which can overcome influence of forest terrain complexity. It makes good use of precious angular function of total station and strong data managing and saving function of PDA. All field observed data is saved by PDA and to calculate and save tree height by PDA programming, which improves monitoring precision greatly, reduces workload and improves working efficiency.

Description

1. Technical field [0001] The invention relates to a method for measuring tree height in forest resource monitoring, in particular to a method for measuring tree height with a total station under the condition that the horizontal distance cannot be measured. 2. Technical background [0002] In the traditional forest resource monitoring, the measurement of tree height has always been a difficult problem to solve. Usually, the altimeter is used to measure the height, the visual estimation method or the combination of the compass, theodolite, tape measure and ruler, and the triangular elevation method. For the measurement of tree height, the above methods all have their disadvantages: [0003] ① In the forest area, when using the compass, theodolite, tape measure, and ruler to measure the height of the tree using the triangular elevation method, it is difficult to measure the horizontal distance due to the constraints of terrain, slope, stand density and other factors, which li...
