Abstract
The present invention proposes a kind of method that smart mobile phone determines single tree volume, it is characterized in that, the single wooden photograph obtained using smart mobile phone, it is known that camera focus, single wood diameter of a cross-section of a tree trunk 1.3 meters above the ground d, inclination angle at arbitrary height, and horizontal direction, diameter of a cross-section of a tree trunk 1.3 meters above the ground width and focus institute are into azimuth.The inclination angle measured according to mobile phone at arbitrary height, can measure height at single wooden arbitrary height.According to known camera focus, and corresponding distance on photograph, the diameter at single wooden arbitrary height can be extrapolated.Volume is finally calculated paragraph by paragraph using important actor method and is taken and is obtained single tree volume value.
Description
First, technical field
The present invention relates to a kind of method that smart mobile phone determines single tree volume
2nd, technical background
Forest survey work in, traditional single tree volume assay method is determined, it is necessary to Dan Mu is cuted down paragraph by paragraph, will
Volume takes and and tries to achieve the volume of timber.Waste time and energy, the destruction of high degree is caused for forest.
Single wooden photograph that the present invention is obtained using smart mobile phone, the azimuth that mobile phone is measured, dip test single tree volume,
The volume of timber can be determined after known single wooden diameter of a cross-section of a tree trunk 1.3 meters above the ground.
3rd, the content of the invention
In order to solve the problem of complicated single tree volume and destruction forest environment are calculated during forest survey works, this hair
The bright a kind of method that single tree volume is determined there is provided smart mobile phone, feature is as follows：
The single wooden photograph obtained using smart mobile phone, the azimuth that mobile phone is measured, dip test single tree volume, specific steps
It is as follows：
(1) at the singly wooden diameter of a cross-section of a tree trunk 1.3 meters above the ground, photograph is shot vertically, it is known that camera focus, singly wood diameter of a cross-section of a tree trunk 1.3 meters above the ground d, inclination angle at arbitrary height, with
And horizontal direction, diameter of a cross-section of a tree trunk 1.3 meters above the ground width and focus institute are into azimuth angle alpha.Utilize formula calculated level distanceAnd according to any
The angle of inclination beta that highly place's mobile phone is measured, can measure height at single wooden arbitrary height.
(2) according to known camera focus f, and corresponding distance on photograph, it can extrapolate at single wooden arbitrary height
Diameter.Dan Mu is divided into 10-20 sections (m sections), volume is calculated paragraph by paragraph using important actor method and takes and obtain single tree volume value.
This invention has advantages below compared with the conventional method：
(1) compared with traditional single tree volume is determined, the present invention need not excessively be surveyed to single wood, time saving and energy saving, more
Dan Mu need not be cuted down.
(2) photography of smart mobile phone, the inclination angle and azimuth determined with reference to mobile phone, you can easily measure Dan Mu are only passed through
The volume of timber.
4th, illustrate
The present invention is further described with example below in conjunction with the accompanying drawings.
Fig. 1 is to combine the diameter of a cross-section of a tree trunk 1.3 meters above the ground and azimuthal horizontal range calculating schematic diagram
5th, embodiment：
A kind of smart mobile phone determines the method for single tree volume, concrete mode：
(1) at the singly wooden diameter of a cross-section of a tree trunk 1.3 meters above the ground, photograph is shot vertically, it is known that camera focus, singly wood diameter of a cross-section of a tree trunk 1.3 meters above the ground d, inclination angle at arbitrary height, with
And horizontal direction, diameter of a cross-section of a tree trunk 1.3 meters above the ground width and focus institute are into azimuth angle alpha.Utilize formula calculated level distanceAnd according to any
The angle of inclination beta that highly place's mobile phone is measured, can measure height at single wooden arbitrary height.
(2) according to known camera focus f, and corresponding distance on photograph, it can extrapolate at single wooden arbitrary height
Diameter.Dan Mu is divided into 10-20 sections (m sections), volume is calculated paragraph by paragraph using important actor method and takes and obtain single tree volume value.
Claims (1)
1. a kind of method that smart mobile phone determines single tree volume, it is characterized in that, the single wooden photograph obtained using smart mobile phone, it is known that
Inclination angle at camera focus, single wood diameter of a cross-section of a tree trunk 1.3 meters above the ground d, arbitrary height, and horizontal direction, diameter of a cross-section of a tree trunk 1.3 meters above the ground width and focus institute are into azimuth.According to
The inclination angle that mobile phone is measured at arbitrary height, can measure height at single wooden arbitrary height.According to known camera focus, and on photograph
Corresponding distance, can extrapolate the diameter at single wooden arbitrary height.Volume is finally calculated paragraph by paragraph using important actor method and is taken and is obtained
To single tree volume value, comprise the following steps that：
(1) at the singly wooden diameter of a cross-section of a tree trunk 1.3 meters above the ground, photograph is shot vertically, it is known that camera focus, singly wood diameter of a cross-section of a tree trunk 1.3 meters above the ground d, inclination angle, Yi Jishui at arbitrary height
Square to, diameter of a cross-section of a tree trunk 1.3 meters above the ground width and focus institute into azimuth angle alpha.Utilize formula calculated level distanceAnd according to arbitrary height
The angle of inclination beta that place's mobile phone is measured, can measure height at single wooden arbitrary height.
(2) according to known camera focus f, and corresponding distance on photograph, the diameter at single wooden arbitrary height can be extrapolated.
Dan Mu is divided into 10-20 sections (m sections), volume is calculated paragraph by paragraph using important actor method and takes and obtain single tree volume value.
