Description
Technical field
The present invention relates to crop multi-angle observation field, more particularly to a kind of portable manual multi-angle observation device.
Background technology
In process of crop growth, in crop canopies structural parameters, biological physical and chemical parameter and photosphere illumination parameter with hat
Layer height is respectively provided with vertical heterogeneous distribution characteristics.If crop nitrogen is at fertilizer deficiency initial stage, because of nitrogen stress occurs first for lower leave morning
It declines；As fertilizer deficiency degree aggravates, in, lower leave show aging successively, but the unobvious of upper strata blade variation at this time, only lacking
When fertilizer stress is serious, upper strata blade just shows certain nutritional deficiency symptom.Therefore, there is an urgent need to developing to crop canopies structure and
Component parameter vertical distribution, particularly in, the remote sensing device and method of lower blade nutrient situation, crop is replenished in time
Nutrient supply avoids or mitigates influence of the nutrient stress to yield composition and quality, so as to ensure the high yield of grain and high-quality.But
Traditional remote sensing is typically only capable to obtain the spectral information at the top of crop canopies, and in canopy, lower part information is difficult to detect so that profit
When carrying out the vertical inverting of component with monocrop entirety canopy spectra, inversion accuracy is not high.Compared to traditional vertical earth observation,
Multiple-angle thinking by being obtained to the observation of ground object target multiple directions than single direction due to can be observed in more detail
The three-dimensional geometry form and space distribution information of object target, peomote the development of agricultural remote sensing Quantitative study.
Therefore it towards multi-angle observation research and application demand, researches and develops to set up the polygonal of various field remote sensors
It is interested to researchers to spend observation device.At present, it is existing to have for ground multi-angle measuring device：U.S. Nebraska is big
The large-scale manipulator Hercules and Goliath for having invented and being suitable for field work are learned, earth's surface transmitting radiation and heat can be carried out
The all-dimensional multi-angle of radiation automatically determines, but the device structure is complicated, of high cost.Chinese Academy of Sciences's geographical science and resource
Research institute has invented a kind of all-dimensional multi-angle ground and has measured platform, although the survey of object all-dimensional multi-angle can be realized
Amount, but the shade of observation platform in itself has seriously affected the observation quality of data, is confined to specific remote sensing observations field.Jiangsu is pedagogical
University devises portable manual all-dimensional multi-angle observation platform, by horizontal limb, matching between vertical scale and sliding block
It closes, realizes and change in the range of horizontal 360-degree and vertical 180 degree, but easily measured height by the shadow effect of zenith arc
Uniquely, and the observation of the tall and big vegetation of plant type (such as corn) is not suitable for it.It is more that Beijing Normal University proposes a kind of portable manual
Angular observation frame solves the problems, such as that height is unique, portability is poor, shadow interference is big in remote sensing observations, but it has measurement
The problem of mobile jib stability is poor.On the basis of further research, Beijing Normal University has also been proposed automatic multi-angle observation dress
It puts, although azimuth and positioning zenith angle can accurately be measured, but still there are device is heavy, mobility is poor, costly etc.
Problem is not suitable for the portable observation of field multi-point.Beijing Research Center of Intelligent Equipment For Agriculture has developed mobile multi-angle
Observation platform can be realized and carry out comprehensive, multi-angle observation to same hot spot, and position of the sensor away from target object can
It adjusts, but there are the angles shifts operating time is long, observation arm height is non-adjustable, and observed object easily occurs under different observation angles
The problem of variation.
In the actual conditions of crop field, crop groups height and coverage can change as Crop growing stage changes, especially
In middle and later periods breeding time, crop groups start to seal ridge, and plant forms are tall and big, and therefore, some volumes are larger, it is unique to measure height
Observation device cannot be introduced into observation.In addition, it also tends to need to carry out the mobile observation and reality between multiple point positions in actual observation
It tests, this requires measuring instrument has, portable and mobility is strong, it is adjustable, small to the destruction of surface vegetation to measure height, operates
The features such as convenient and efficient, adaptable, and existing observation device can not still meet these requirements simultaneously.
