Ground feature bidirectional reflectance indoor measurement device

Abstract

The invention discloses a ground feature bidirectional reflectance indoor measurement device, which comprises a support, an inner circular track and an outer circular track, the inner circular track and the outer circular track can be coaxially rotated, a round table which is coaxial with the outer circular track is arranged in the outer circular track, the round table is mounted on the support through a lifter, a first vertical rod which is connected through a first round dial is arranged on the upper surface of the inner circular track, and a light source is mounted at the upper end of the first vertical rod through a first horizontal rod; a second vertical rod which is connected through a second round dial is arranged on the upper surface of the outer circular track, an optical lens ismounted at the upper end of the second vertical rod through a second horizontal rod, and the optical lens is connected to a panchromatic spectrograph through an optical fiber. The ground feature bidirectional reflectance indoor measurement device has the advantages that: according to the requirement of measurement, the azimuth and inclination of light can be continuously adjusted, meanwhile, the azimuth and inclination of spectral measurement can be continuously adjusted, the distance between a to-be-measured object and the light source can be kept unchanged, and thereby the bidirectional reflectance spectrum of a ground feature can be continuously measured.

Description

technical field [0001] The invention relates to the technical field of quantitative remote sensing, in particular to an indoor measuring device for two-way reflectivity of ground objects. Background technique [0002] Remote sensing technology can obtain the reflection, radiation and backscatter information (hereinafter referred to as reflection) of objects on a large scale and in real time, and realize the efficient cognition of characteristics of objects on land, resources, surveying and mapping, meteorology and military reconnaissance. with broadly application foreground. With the gradual development of earth observation and remote sensing technology in the direction of quantitative application, the reflection characteristics of ground objects have become an important basis and basic data for object identification, geological prospecting, monitoring of crop diseases and insect pests, and sensor development. Refinement research has been widely valued at home and abroad. ...
