Abstract
The invention discloses a method for measuring bush biomass in real time through mobile phone/tablet personal computer single photo arbitrary shooting. According to the method, a common smart phone or a tablet personal computer with the photographing function is used as a tool, the quantity of bushes participating in biomass computation is recorded by shooting a fixed bush sample plot through an angle gauge, and factors of bush height, width, canopy height and the like, are computed through a method for recovering bush space coordinates through photography, and the sample plot bush biomass is computed through a height, width and canopy height regression model. The method greatly improves the bush investigation precision and operating efficiency, and can greatly reduce the cost.
Description
One, technical field
The present invention relates to the shrub measuring method in a kind of forest inventory investigation, particularly a kind of mobile phone/panel computer single-sheet photo is photographed arbitrarily and is calculated frutex biological metering method in real time.
Two, technical background
Traditional Bush biomass investigation method adopts Investigation for per wood methods combining airborne remote sensing to sample-plot survey usually, obtains basic factors of enumeration, but above-mentioned all technology have its obvious shortcoming and defect:
1. field investigation adopts artificial visual estimation or simple tool to obtain data, and precision is lower, and slow in action during actual measurement, the cycle is long.
2. data processing adopts manual mode to carry out, and calculating, statistical work amount are comparatively large, and need a large amount of artificial inputs, cost is high, inefficiency.
So when adopting traditional Investigation for per wood methods combining airborne remote sensing to sample-plot survey, inevitably bring a lot of trouble and precision is not high, inefficiency.How Investigation for per wood precision is investigated in raising, reduces costs, raises the efficiency and become this area scientific and technical personnel problem anxious to be resolved.
Three, summary of the invention
In order to overcome a lot of troubles that existing Bush biomass investigation method process is inevitably brought, improve accuracy of observation and work efficiency, the object of the invention is a kind of mobile phone/panel computer single-sheet photo to photograph arbitrarily in real time measuring and calculating frutex biological metering method, it is when accuracy of observation improves, significantly reduce the workload of interior field operation, improve efficiency, overcome the shortcoming that prior art exists.
A kind of mobile phone/panel computer single-sheet photo is photographed arbitrarily and is calculated frutex biological metering method in real time, it is characterized in that: with common intelligence with the mobile phone of camera function or panel computer for instrument, by photographing to fixing bushy, angle gauge record is utilized to participate in the shrub book of biomass calculating, the method of shrub volume coordinate is recovered by photography, the factors such as computed altitude, width, canopy height, calculate sample ground Bush biomass with height, width, canopy height regression model.
The method that angle gauge calculates shrub number is as follows: install angle gauge sheet additional at mobile phone or panel computer, get section factor Fg=4, angle gauge sheet bayonet socket 2cm, carries out around survey bushy, and the shrub number that biomass calculates can be participated in record.
Extract the method for shrub height, width, canopy height, as follows: at angle gauge around surveying the method shrub of counting being adopted to horizontal right photographic measurement simultaneously, according to formula u/x=f/y=v/z, wherein 1/u+1/v=1/f, extract each unique point x, y, z of shrub, computed altitude, width, canopy height.
Calculate the method for biomass, as follows: to calculate individual plant Bush biomass formula: Wi=aD

d, the overall accumulation in sample ground is W=W
1+ W
2+ W
3+ ... ..+Wn.
This invention compared with prior art has the following advantages:
1. adopt ordinary digital camera to take pictures, light, flexible, period from practical measurement is short.
2. by microcomputer modelling process data, obtain the factors of enumeration such as filling is high, width, height, precision is high.
3. measured data is by computer statistics, calculating, and interior industry workload is little, and efficiency is high.
