Description

A portable tree altimeter sampler

technical field

The invention relates to the technical field of measuring machinery, in particular to a portable tree height measuring sampler.

Background technique

Tree height is an important factor of stand, it is not only a quantitative index of stand but also a quality index of stand; it is the most important measurement factor in forest investigation and management, and is often used to calculate the related factors such as standing timber volume, site index and forest growth. It is an important variable, but the measurement of tree height is time-consuming and labor-intensive, and it will also produce a lot of errors. At present, the height measurement methods adopted for trees at home and abroad mainly include visual tree height measurement, tree height measurement by measuring ruler, and total station method. Height, ultrasonic method to measure tree height, laser ranging method to measure tree height, and aerial photography, analysis photo method to measure tree height, although large measuring instruments such as theodolite and total station can obtain high measurement accuracy, but using this method Such instruments have many inconveniences such as difficulty in carrying, cumbersome operation, and the need for professional measurement knowledge. Hand-held height measuring tools that are easy to carry and operate are cheap and easy to use, but their measurement accuracy is not high. Mechanical friction causes measurement errors and needs to be adjusted frequently. The distance between trees with high canopy closure is closer, the crown width overlaps and covers each other. Generally, it is impossible to see through and the top of the tree body. Therefore, similar triangles and The altimeter based on the principle of trigonometric function cannot accurately measure the height of trees. Most altimeters can only accurately measure the height of objects on flat ground or on the ground with a small slope. The difference is obtained after the second measurement of the height, which increases the workload of the measurement personnel, and it is easy to introduce measurement errors.

At present, most of the existing forest tree altimeter samplers can only sample branches and leaves and cannot collect them. When the trees are taller, it is more difficult to collect branches and trunks, which cannot meet the needs of sampling personnel at the same time. It is difficult to see through, and the branches and leaves are denser. If the device collects branches and leaves without being able to move, it will increase the difficulty of sampling and may cause greater damage to the branches and leaves at high places.

Therefore, it is necessary to provide a portable tree altimeter sampler to solve the above technical problems.
