Description
Technical field
The utility model relates to a kind of measurement apparatus, and specifically a kind of ground-object spectrum measures auxiliary stand.
Background technology
Light-matter interaction causes the electronic transition between material interior atoms and molecular entergy level, the absorption, transmitting, scattering etc. of material to light are changed on wavelength and strength information, the reflections off objects rate curve utilizing continuous wavelength to measure forms reflectivity wave spectrum, is the clutter reflections spectral profile often said.The principal element affecting ground-object spectrum curvilinear motion feature is then this object constituent, structure and surface state.Therefore, ground-object spectrum analysis, as a kind of important analysis means, in agricultural, environment, Di Kuang, production quality control etc., all plays effect greatly.
Owing to measuring the difference of mode, reflectivity wave spectrum can measure mode according to the lighting system of projectile energy and reflected energy and comprise direction-directional reflectance ratio wave spectrum, hemisphere-directional reflectance ratio wave spectrum, direction-hemispherical reflectance wave spectrum and hemisphere-hemispherical reflectance wave spectrum Four types.Because many objective condition limit, be difficult to the ideal reflectivity wave spectrum measuring this Four types, aviation and satellite optical remote sensing technical limit spacing be the reflected sunlight energy (see Fig. 1) of some specific observed ray of atural object, can be approximated to be the direction-directional albedo data of the first, namely projectile energy lighting system is parallel direct light, maybe scattered light can not ignored, spectroscopic measurement instrument only measures the reflected energy of certain specific direction, therefore, general data source or the direction-directional albedo data of employing is studied in remote sensing application both at home and abroad at present.

Existing metering system mainly contains Indoor measurement and field survey two kinds.Indoor measurement is that sample is taken laboratory, utilizes artificial light source to measure, and the precision of measurement result is high, but does not reflect actual state of nature; And field survey, be that instrument is taken on the spot, utilize solar radiation as lighting source, utilize diffuse reflection reference plate measurement of comparison, obtain the reflectance spectrum information of target, better can reflect the Spectral Characteristic of atural object state of nature.
But, field ground feature spectral measurement is a complex process needing to consider various spectrum influence factor, and the spectroscopic data obtained is sun altitude, solar azimuth, cloud, wind, relative humidity, incident angle, search angle, instrument sweep velocity, instrument field angle, the sampling interval of instrument, spectral resolution, slope aspect, the coefficient result of various factors such as the gradient and the spectral characteristic of target own.Require during measurement to select the suitable time, fine, cloudless or partly cloudy, wind-force is little; The Light polarizing interference of shade and surrounding objects must be avoided during probe location, also have certain requirement, to prevent light pollution etc. to the dressing of operator.In addition, the supplementary of environmental parameter, exception condition, the height of probe, instrument parameter and observed object is also required to record in detail.Only in this way, measured result is only reliably, and has comparability, can provide foundation for figure remote sensing as decipher and rebuilding spectrum.
Compare all Multiple Constraints of field ground feature spectral measurement, indoor spectral measures and requires lower to environmental background, but ground-object spectrum instrument conventional in the world at present, as the FieldSpec series of ASD company of the U.S., the spectrometers such as the HR2000/4000 of ocean color company of the U.S., the mensuration of its indoor spectral is mainly for soil, crops, blade, mineral, ore, the mensuration of the material composition of the samples such as water and the spectral signature mutation analysis caused by inner structure, though estimating precision is higher, but weak point is that its metering system does not consider the change of light source incidence angle and albedo measurement angle, measurement result is not the Spectral Characteristic under object state of nature.Therefore, its result can not be analyzed with the ground-object spectrum information obtained based on aviation or space platform, and range of application and the popularization field of its achievement in research are subject to direct restriction.
