Description
Technical field
The utility model is a kind of large scale vegetation coverage aviation Dynamic Acquisition system (LSVC-ADAD) of using in water conservancy and water and soil conservation monitoring business, it is used to field on a large scale, particularly the staff is difficult to arrive regional earth's surface and covers and dynamically observe, take pictures,, batch whole direct measuring large scale vegetation coverage information real-time, dynamic in conjunction with vegetation coverage Dynamic Acquisition system (VC-DAS), belong to the water conservancy industry technical applications.
Background technology
Vegetation coverage refers to comprise the canopy of all vegetation of Qiao, filling, grass and crops, the ratio that the planimetric area of branches and leaves on growth district ground accounts for the Research statistics region area.As the important indicator that characterizes vegetation covering situation, vegetation coverage is that water conservancy and water are protected industry and relatively paid close attention to and need badly the basic data of obtaining, and in the business such as the modeling such as rainfall-runoff, the soil erosion, non-point pollution, evapotranspiration and draught monitor, has widespread use.Extract the key issue that vegetation coverage information relates to, the one, the vegetation vertical projection is obtained in requirement, and the 2nd, the coverage value difference of vegetation in different study area areal extents, have scale effect, and the correlation model scale effect is had to certain influence.Consider model application staff's to than the information requirements of large scale vegetation coverage and field work time the accessibility, hardware unit platform and the coverage information extraction software system of larger area scope ground vegetation image photo obtained in development, becomes the active demand of obtaining large scale vegetation coverage information.
Obtaining at present larger study area area vegetation coverage information can calculate and two kinds of approach of whole directly measurement by sample statistics.The sample statistics measuring and calculating, be according to the statistics requirement, extracts the sample prescription zone of some in study area, estimates the vegetation coverage of whole survey region by measuring and calculating sample prescription zone vegetation coverage, and the ground investigation workload is larger.Whole direct measuring, by study area vegetation growth environmental element, space-time key element and vegetation coverage ground survey data are coupled, set up the statistical model of vegetation coverage in some scale, or utilize the remote sensing image wave spectrum to extract vegetation information, set up correlationship with vegetation coverage again, or use the method that image picture element is decomposed to calculate vegetation coverage.Wherein, empirical model mainly is applicable to the more consistent survey region of vegetation growth situation, as the monitoring of larger area crops vegetation cover degree, requires on the basis that obtains ground vegetation coverage data, obtain a large amount of vegetation growth environmental elements and space-time key element, institute's model of setting up is portable poor, remote sensing technology provides possibility for the measurement of the inconsistent cover degree on a large scale of surface vegetation growing state, utilize spectral information and ground vegetation coverage to set up relationship model, obtain the Ground vegetation coverage, the method can roughly be divided into statistical model method and physical model method, the former has the calculating of simply being easy to a little, but need a large amount of measured datas, the space-time transplantability is poor, the latter vegetation spectral information characteristics, choose the vegetation index estimation vegetation cover degree that better correlativity is arranged with vegetation cover degree, universality is good, but it is poor to eliminate the background information capability of influence, precision is relatively low, pixel decomposition model method, have relatively high expectations to the remotely-sensed data spatial resolution, limited the method popularization.As can be seen here, above three kinds of methods cut both ways, and may be used to the information extraction of larger area macroscopic view vegetation coverage, work efficiency is higher, but all need a large amount of measured datas, the contradiction of algorithm transplantability and precision is comparatively outstanding, and the availability of remotely-sensed data and actual effect can't ensure.How comprehensive above the analysis, avoid large number of ground actual measurement work, obtains the effective ground vegetation information of larger area, by the real-time whole direct measuring of dependable algorithm ground macroscopic view vegetation coverage information, becomes the urgent business demand that water conservancy and water are protected industry.
