Vegetation canopy spectrum two-way reflection distribution observation support and method

Abstract

The invention provides a vegetation canopy spectrum two-way reflection distribution observation support and method. The vegetation canopy spectrum two-way reflection distribution observation support comprises a triangular support capable of adjusting the folding and unfolding amplitude and a first field-of-view frame. A group of telescopic supporting rods with the adjustable supporting heights anda sharp corner structure are correspondingly arranged at center of the top and the bottom of the triangular support. The telescopic supporting rods are sequentially provided with supporting adjustingscales, fixing buckles and observation zenith angle distance measuring tapes from bottom to top, a second field-of-view frame with the side length equal to that of the first field-of-view frame is arranged on the peripheral boundary of the telescopic supporting rods, and the second field-of-view frame is formed by connecting a plurality of equal-length connecting rods for marking azimuth angle scales end to end. All the structures are tightly connected, and the vegetation canopy spectrum two-way reflection distribution observation support has the advantages of being simple in structure, light, convenient to carry, suitable for field on-site observation and suitable for uneven ground with elevation changes.

Description

technical field [0001] This application relates to the field of remote sensing ground testing application technology, in particular, to a support and method for observing the two-way reflectance distribution of vegetation canopy spectrum. Background technique [0002] Remote sensing satellites are artificial satellites used as remote sensing platforms in outer space. The remote sensing technology using satellite as a platform is called satellite remote sensing. Typically, remote sensing satellites remain in orbit for several years. Satellite orbits can be determined as needed. Remote sensing satellites can cover the entire earth or any designated area within a specified period of time. When running along a geosynchronous orbit, they can continuously remote sense a designated area on the earth's surface. [0003] The sensors on remote sensing satellites have gradually developed from single-angle to multi-angle. In the field of quantitative remote sensing, in order to study...

AI Technical Summary

Problems solved by technology

[0003] The sensors on remote sensing satellites have gradually developed from single-angle to multi-angle. In the field of quantitative remote sensing, in order to study satellite multi-angle remote sensing theory, research on multi-angle ground verification and inversion algorithms is required. Early multi-angle observations were completely carried out by experimenters with handheld spectrometers Not only is the operation cumbersome and the process is complicated, but also the operation time is relatively long, it is difficult to obtain more accurate experimental data, and ground multi-angle observation devices are required

[0004] The existing ground multi-angle observation device has complex components, heavy volume, and is not easy to carry. It is not suitable for field observation, nor can it be applied to uneven ground with elevation changes.
