【摘要】 简要回顾了印度遥感卫星系列的发展历程;给出了IRS-P5卫星及传感器的有关性能参数,并与IKONOS、SPOT5 HRS做了初步比较;详细论述了IRS-P5使用有理函数模型的定位方法。最后,使用中国北京地区的立体像对数据进行了有关试验研究,结果表明,在良好的地面控制点的支持下,平面和高程精度均可达到5m,满足国家1∶50000基本比例尺地形图测图规范要求。更多还原

【Abstract】 In this paper,the development of Indian remote sensing satellite series is reviewed,the specifications of IRS-P5 satellite platform and sensor are introduced and compared with the IKONOS、SPOT5 HRS.The positioning algorithm using Rational Function Model(RFM) of IRS-P5 is described in detail.Experiment was carried out using stereo pair of Beijing hilly area.The results show that with high accurate and well-distributed Ground Control Points(GCPs) the plane and elevation accuracy of IRS-P5 imagery could reach 5-meter and meet the mapping requirements of national topographic map 1:50,000.更多还原
