基于GPS数据的OMIS图像航线校正研究

随着GPS实时定位技术的发展,GPS广泛地应用于舰船、飞机等动态目标的导航定位。机载GPS数据用于遥感图像航线校正就是利用机载GPS数据模拟计算出飞机飞行的各种姿态参数,从而对由机载成像光谱仪获得的遥感图像进行方位校正,使遥感图像达到几何粗校正的结果,为几何精校正打下基础。OMIS是中国科学院上海技术物理所新近研制的128通道成像光谱仪,并于1998年8月在江苏常州进行了试验飞行。结合这次实验,利用机载GPS数据对飞行图像进行了航线校正研究,并结合实际飞行数据进行了实验,获得了较好的结果。

Study on Skyway Rectification of OMIS Image Using Air-borne GPS Data

With the development of GPS real time position technology, GPS is widely used in navigation and position for moving objects such as ship and plane. The air\|borne GPS data used for the skyway rectification is used to simulate the fly way, calculate the parameters, and then do the orientation rectification for remote sensing images,so as to make a base for precise geometric rectification.OMIS is an imaging spectrometer made recently by the Institute of Shanghai Technology and Physics. A test fly was conducted in Changzhou city, Jangsu province at August,1998. In this article, an experiment for skyway rectification of OMIS image using airbore GPS data is done and a good result is achived in the experiment.
