Description
Technical field
The utility model is related to a kind of tree height measurement devices.
Background technology
Tree height is an important indicator of forest survey, and important work is played in forest resource monitoring and Forestry Investigation
With, and it is always an insoluble problem to set high measurement.In actual operation, since mountainous region slope is steep, trees are tall and big, tree
Intensive between wood, the problems such as forest canopy density is high, forest workers's generally use eye estimating method or height finder are surveyed high.
However eye estimating method is closely related with personal experience, measurement accuracy has no to ensure.It is widely used in existing height finder
Mainly there are Bo Lulai height finders and laser tree height measuring instrument in ground, also has certainly and sets high side suitable for being measured under tree crown obstruction conditions
Method --- total station survey method.
Bo Lulai height finders（Forest height gauge developments of the Li Jianhua based on triangle principle and application）：Bo Lulai height finders
According to tangent trigonometric function principle（h=Ltanθ）It designs.When surveying high, first measure a measuring point to trunk standard level
Distance（General provision is 15,20,30 or 40m when design）, then taken aim at depending on treetop and after pressing drag knob with instrument in measuring point
Inclination angle theta is obtained to be carved at the corresponding θ of reading dial because being dedicated height finder and set high h accordingly, in this way, using above-mentioned
Operating method, you can the height of trees is directly read by the vertical needle of height finder.
Bo Lulai height finder compact structures, easy to carry, altimetry precision can also meet the needs of routinely forest survey, institute
To be always to produce to apply height finder the most universal.But Bo Lulai height finders require it is every survey one plant of trees height it
Before, it is necessary to the horizontal distance of a full-length is measured first（15,20,30 or 40m）Survey station is set, this is in canopy density
It is particularly difficult in larger montane.First, being limited by landform in woods, standard level distance should not be measured, second is that even if measuring
Standard level distance, mutually to be blocked by tree crown influenced, and often can't see treetop again.It is every survey one plant of trees height it
Before, it is necessary to the horizontal distance of a full-length is measured first（15,20,30 or 40m）Survey station is set, this is in canopy density
It is particularly difficult in larger montane.First, being limited by landform in woods, standard level distance should not be measured, second is that even if measuring
Standard level distance, mutually to be blocked by tree crown influenced, and often can't see treetop again.
Laser tree height measuring instrument（Application of the Xu Ji richness laser range finders in tree height measurement）：Laser range finder is placed
In void spaces, in order to which light beam can cover institute's assize wood.The beam alignment tree root position that laser range finder is sent out, obtains
One distance parameter L1；Continue to adjust light beam, be allowed to be directed at treetop position, obtains the angle parameter that light beam is presented with plane；
The distance parameter L2 of treetop position and laser range finder.These three parameters be input to specific mathematical function calculation formula it
In, just obtain the corresponding high numerical value of tree.Such mode also can be measured quickly and accurately in topography unevenness, but in reality
In the measurement process of border, the leaf of treetop position can stop laser beam, so the parameter L2 obtained can and actual numerical value generate deviation,
And then measurement accuracy is influenced, so such mode is suitable for measuring winter Deciduous tree.If tree ebon leaf is various,
Another measurement method may be used：Laser range finder is positioned at trees a certain distance, A is used in combination to indicate its position, is set
Root position is denoted as B, and treetop position is denoted as C；The distance between A points and B points indicate that the vertical range of A and straight line BC is used with L1
L2 is indicated；And calculate separately out straight line AC, BC and horizontal angle.By simple numerical computations, in each section parameter generation
Enter among mathematical formulae, so that it may which high distance is set with accurate calculate.
It is not limited by the trees condition of production, and do not limited by landform, but want that it is high, which to measure tree by means of which,
It asks tested area spacious, is difficult to carry out in the intensive woods of trees, and the laser measurement device of height finder application requirement can be reached
It is still expensive.
Total station survey method（103486991 A of patent application publication CN）：It measures by means of which and improves tree
High measurement working efficiency measures trees any place diameter with apart from ground level by using total powerstation, and then obtains
The trees height and the volume of timber simplify field operation and measure, alleviate measurement operation intensity, while solving can not when tree crown is blocked
It measures and sets high problem.But points for attention are more during using total powerstation, such as the observation instrument under sunlight irradiation,
It should hold up an umbrella to instrument, and take sky shade, in order to avoid influence accuracy of observation；When setting up instrument on tripod, wood is used as far as possible
Tripod processed, because vibration may be will produce using metal tripod, to influence measurement accuracy etc., and the valence of total powerstation
Lattice are generally expensive.
