Abstract
The invention relates to the technical field of forest research equipment, in particular to a multifunctional arbor tree height, crown width and breast diameter accurate measuring instrument which comprises a rotary machine base, a plurality of supports, a processing device and a detecting device.
Description
Technical Field
The invention relates to the technical field of forest research equipment, in particular to a multifunctional arbor tree height, crown breadth and breast height accurate measuring instrument.
Background
As is well known, in the process of forest investigation and scientific research, the height, crown width and breast height of a tree are 3 important indexes for researching the growth of the tree and the growth change of forest stands. The currently common method for measuring crown width of a tree crown is that a measurer stands in the east, south, west and north directions under the tree in sequence, and the edge of the tree crown in each direction is determined by adopting a head-up observation method; then the distance from the edge of the tree crown to the trunk, namely the length of the crown breadth, is measured by a measuring tape. This method has the following disadvantages: (1) The observer needs to look up, and the measurement is very tired for a long time; (2) When the tree crown is observed in a head-up manner, the visual observation position is difficult to be the projection position of the edge of the tree crown, and the measurement precision is influenced; (3) The direction of an observer in the tree crown is difficult to determine, and the observation precision is influenced.
The breast diameter is usually measured by a vernier caliper, a tape measure or a measuring tape, for trees with overlarge diameters, the vernier caliper cannot meet the measurement requirement, the tape measure and the measuring tape can only measure the circumferences and then obtain the breast diameter through calculation, for large trees, the measurement can be completed by cooperation of several people, and the eyes of an observer are higher than the measuring tape, so that a large measurement error is caused. And the current instrument can only carry out single measurement, which causes the waste of manpower and financial resources.
