摘  要:
多角度光谱信息采集系统可以测量植被作物的双向反射特性,配合高光谱分辨率遥感卫星影像,反演得到植被的结构参数信息。多角度光谱信息采集系统主要包括机械系统与控制系统两大部分。机械系统由天顶机构与方位机构组成,方位圆轨道直径4 m,天顶圆导向轨道半径1 m,其特点在于光谱仪视场内无阴影,结构简单,便于安装、运输。控制系统提供多种测量模式以满足不同的观测需求,观测参数可根据需要在控制平台中手动输入,更改方便,操作简单。

摘  要:
Multi-angle spectral data acquisition system can measure the bidirectional reflectance characteristics of vegetation and crops. With the high spectral resolution images from remote sensing satellites,the parameter information of vegetation structure can be obtained. The multi-angle spectral data acquisition system includes mechanical system and control system.Mechanical system is consisted of zenith institution and azimuth institution. The diameter of azimuth circle orbit is 4 meters while the radius of guide rail for zenith circle is 1 meter. The acquisition system is characterized by simple structure, easy installation and transportation. Furthermore, there is no shade in the spectrometer′s view. Control system provides a variety of measurement modes to meet the needs of different observations. The observation parameters can be entered into control platform so that it can be easily alteres and operated.
