一种多角度观测系统几何精度的评估方法
A Method of Assessing Geometric Precision of Multi￣Angle Observation System
摘要
Abstract
Multi￣angle observation system is used to measure bidirectional reflectance characteristics of objects in remote sensing experiment. With high spectral resolution images of remote sensing satellites three￣dimensional structural information of the objects can be figured out. Geometric precision of multi￣angle observation system di￣rectly affects the range of the targets and the data collected from the cultures. Evaluating the precision not only can provide the precision parameter for laboratory personnel when choosing the test equipment but also help to ensure the range of observation targets. The radius of minimum enveloping circle was regarded as the evaluation parameter in this paper. This provided readers with an assessment method of the multi￣angle observation system geometric ac￣curacy. And the geometric precision of self￣developed multi￣angle observation system was assessed. Besides the theoretical observation range and actual observation range considered the geometric precision were calculated and offered to reference.关键词
