Tree height measuring device and measuring method thereof

Abstract

The invention discloses a tree height measuring device and a measuring method thereof. The tree height measuring device comprises a foldable telescopic base, and a telescopic rotary knob capable of adjusting the height of the foldable telescopic base. A horizontal control table is connected to the foldable telescopic base through a rotary table, a sighting telescope is installed on the horizontalcontrol table, the focal length of the sighting telescope can be adjusted by a sighting telescope rotary knob, and a control and display device is installed on the horizontal control table. A rotatable laser sight is installed at the front end of the horizontal control table, the sighting telescope rotary knob controls rotation of the laser sight, and a diastimeter is installed at the front end ofthe horizontal control table. A movable telescopic vertical ruler is installed on the diastimeter. By means of the device, the rigid tree height can be precisely measured, the influence of natural conditions is small, and the device is high in operability, good in stability and high in measuring efficiency.

Description

technical field [0001] The invention relates to a tree measurement device, in particular to a tree height measurement device and a measurement method thereof. Background technique [0002] Rigid trees that grow naturally tend to be taller, and the precise height of rigid trees is required in forestry investigations and many engineering designs. Therefore, it is necessary to accurately measure the height of rigid trees. At present, the measurement of the height of rigid trees mainly relies on manual operation, which has large errors and high measurement costs. [0003] The Chinese patent with the patent number ZL201520101879.9 discloses a laser tree height measuring instrument, which includes a horizontal telescopic ruler. The front end of the ruler is equipped with a steel positioning head cover, and the rear end is equipped with a connecting seat. The connecting seat is connected with the laser housing, the laser housing is equipped with a positioning knob, and the laser h...

Problems solved by technology

Using light balloons for measurement, first of all, forestry production often has dense branches and leaves, it is difficult to determine the tree tops, observation is difficult, the actual error is large, and the efficiency is low; when encountering windy weather, the light balloons are too light, and the accuracy cannot be guaranteed; and storage The gas chamber stores hydrogen or helium, and after use, it is squeezed back into the gas storage chamber by the balloon, which is not easy to realize
