Description
First, technical field
This technology invention is related to field of forestry, and being used for the non-contact remote-wireless assize diameter of a cross-section of a tree trunk 1.3 meters above the ground in particular to one kind passes
Sense technology.
2nd, technical background
At this stage during forest resourceies examination, the measurement of tree breast-height diameter is the most important link that it is checked, at this stage
Main or using human contact's formula the measuring method in the measurement operation process in China, measurement accuracy is low, inefficient, work
Amount consumption is big, and the tree measurement being grown in for some in complex environment is more difficult.
3rd, the content of the invention
This technology invention in order to realize it is easy, quick, accurately and real-time measure tree breast-height diameter, a kind of non-contact single-direction and dual-direction scanning
Formula tree breast diameter survey method
The object of the present invention is achieved like this：
1) infrared distance measuring device is measured to by the Edge Distance p1 of assize, intersection point D using infrared distance measuring device1, utilization is infrared
The scanning of line range unit is moved infrared scanner by the assize diameter of a cross-section of a tree trunk 1.3 meters above the ground in parallel lines, when to move in parallel distance be d,
Infrared ray is p2, intersection point D apart from measured object distance2, D1To D2Point distance beAfter
The continuous infrared range-measurement system distance that moves in parallel is d, scans D3, D4... until Dn(by another survey edge of assize), is similarly asked
Go out D2D3、D3D4……Dn-1Dn, then half cycle A side lengths are CA=D1D2+D2D3+…..Dn-1DnThe summation of scanning distance.
2) when distance d is sufficiently small, semi-perimeter CAThen it can be neglected closer to actual value, measurement error.If the single sweep operation diameter of a cross-section of a tree trunk 1.3 meters above the ground
Then diameter of a cross-section of a tree trunk 1.3 meters above the ground girth may approximately equal to 2xC to CAThat is twice of CA。
3) if it is desired to more accurate measurement also needs to antiparallel scanning, C is similarly obtainedB, diameter of a cross-section of a tree trunk 1.3 meters above the ground total length is then C=CA+CB。
4) this invention has advantages below compared with the conventional method：
1. it is of the invention can it is easy, quick, accurate, measure tree breast-height diameter in real time, provided accurately for the measurement of arboreal growth situation
Data.
2. financial cost and labour are saved using contactless device.
3. the present invention can be used in the position that artificial condition can not reach, to tree breast-height diameter telemeasurement, overcoming traditional measurement
Difficulty.
4th, illustrate
The invention will be further described below in conjunction with the accompanying drawings., below will be right in order to illustrate more clearly of this technology inventive embodiments
The required accompanying drawing used is briefly described in technological invention description.
Fig. 1 is the measuring method figure for being used to measure tree breast-height diameter of this technology invention one embodiment.
5th, embodiment
Below in conjunction with the accompanying drawing in this technology embodiment of the method, the technical scheme in this technology embodiment of the method is carried out it is clear,
It is fully described by, it is clear that described embodiment is only this technology method part of the embodiment, rather than whole embodiments.
Based on the embodiment in this technology method, institute that those of ordinary skill in the art are obtained under the premise of creative work is not paid
There is other embodiment, belong to the scope of technical method protection.
Fig. 1 is the measuring method figure for being used to measure tree breast-height diameter of this technology invention one embodiment.As shown in figure 1, using red
Outside line range unit measures infrared distance measuring device to by the Edge Distance p1 of assize, intersection point D1, utilize infrared distance measuring device
Scanning is moved infrared scanner by the assize diameter of a cross-section of a tree trunk 1.3 meters above the ground in parallel lines, when to move in parallel distance be d, infrared ray distance
Measured object distance is p2, intersection point D2, D1To D2Point distance beContinue to move in parallel infrared
Distance by stadimeter is d, scans D3, D4... until Dn(by another survey edge of assize), similarly obtains D2D3、D3D4……Dn-1Dn,
Then half cycle A side lengths are CA=D1D2+D2D3+…..Dn-1DnThe summation of scanning distance.
Further, when distance d is sufficiently small, semi-perimeter CAThen it can be neglected closer to actual value, measurement error.If
Then diameter of a cross-section of a tree trunk 1.3 meters above the ground girth may approximately equal to 2xC to single sweep operation diameter of a cross-section of a tree trunk 1.3 meters above the ground CAThat is twice of CA。
Further, if it is desired to more accurate measurement also needs to antiparallel scanning, C is similarly obtainedB, diameter of a cross-section of a tree trunk 1.3 meters above the ground total length is then C=CA+CB。
