Tree height and crown breadth measuring device and measuring method thereof

Abstract

The invention relates to a tree height and crown breadth measuring device and a measuring method thereof. The tree height and crown breadth measuring device comprises tree height measuring equipment, crown breadth measuring equipment and a data processing module. An angle adjusting knob on the crown breadth measuring equipment is used for controlling the crown breadth measuring equipment to rotate around the rotating axis and the tree height measuring equipment to rotate up and down relative to the crown breadth measuring equipment. The crown breadth angle sensor is used for monitoring the rotation angle [alpha] of the crown breadth measuring equipment body in real time, the crown breadth laser range finder is used for measuring the distance h between the crown breadth measuring equipment body and a crown in real time, and the tree height angle sensor is used for monitoring the rotation angle [beta] of vertical rotation of the tree height measuring equipment body in real time. The tree height laser range finder is used for measuring the distance H between the tree height measuring equipment body and a tree crown in real time. The data processing module is used for receiving the rotation angle [alpha], the distance h, the rotation angle [beta] and the distance H in real time and calculating the crown breadth and the tree height. The tree height and crown breadth measuring device has the advantages of achieving high-precision measurement of automatic measurement and automatic calculation of tree height and crown breadth.

Description

technical field [0001] The invention relates to the technical field of tree measurement, in particular to a tree height and crown width measuring device and a measuring method thereof. Background technique [0002] In forestry surveys, tree height and crown width are important indicators for evaluating tree quality. Among them, the tree height refers to the distance between the rhizome above the ground and the top of the tree crown, and the crown width refers to the width of the part composed of branches and leaves above the trunk. [0003] At present, the commonly used tree height measurement tools are the Brulay altimeter and the Christon altimeter, but the measurement errors of these two altimeters are relatively large. Patent No. CN209727051 discloses an instrument for quickly measuring tree height and crown width, which requires an external power supply and is not suitable for field measurement work. Patent No. CN206818104 discloses a new tree height measuring device ...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a tree height and canopy measuring device and its measuring method, which solve the problem that the existing tree height and canopy measuring devices need manual auxiliary measurement and calculation, and the operation is complex and cumbersome. And the problem of low precision, and solves the technical problem that the existing tree height and crown width measuring device cannot simultaneously realize the automatic measurement of tree height and crown width and the high-precision measurement of automatic calculation
