Description
Technical field
The utility model relates to technical field of measuring equipment, in particular to a kind of tree height measurement device.
Background technique
Tree height refers to that trees rhizome from ground in forestry scientific research, is ground to the distance between treetop or height
Study carefully personnel often to need to measure the basic growth parameter(s) of plant, and setting height is then a very important parameter；Cut down tree
The random length of wood can be measured with tape measure, and the height of standing tree is in 2m hereinafter, can at will measure；And the height more than 2m or more
Degree need to be then measured by certain altitude meter device.
Bo Lulai height finder that the general common with good grounds triangle principle of height finder is measured is carried out according to scaling principle
The Chris of design collects height finder, and both height finders are generally difficult to grasp, and is also easy to produce error in measurement；And
It generally seldom goes to measure very high trees, the substantially conclusion that the observation several years can be grown after afforestation, tree in forestry research
Height does not exceed 10 meters substantially, thus those skilled in the art need it is a kind of without geographical restrictions, it is not dense by branches and leaves
Degree influences and can on the ground 10 meters of trees below be carried out with the device of elevation measurement.
Utility model content
The purpose of the utility model is to provide a kind of tree height measurement devices, when carrying out tree height measurement not by the limit of region
System, is not influenced by the dense degree of tree branches, can the trees to 10 meters or less arbitrary heights carry out accurate elevation measurement,
And it is extremely convenient that the tree height measurement device is grasped, and in measurement, gauger can be looked squarely by the tree height measurement device
Treetop can look squarely graduation mark when reading height parameter, avoid the generation of error.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of tree height measurement device, including mobile phone terminal and measurement module, the measurement module include Sopwith staff ontology, cunning
Wheel, tape measure, first laser level meter, mobile observation end and wireless image recording machine；The Sopwith staff ontology is by least five section Sopwith staff section sets
