摘要
北京一号是具有双遥感器的灾害监测小卫星,其星载的CCD多光谱传感器可以获取32m的多光谱数据。本文对2005年11月14日的北京天津地区遥感图像数据进行了几何精校正研究,根据图像自身特点和后续研究需求采用有限元模型对空间位置进行校正,采用最临近法重新采样,矫正后的图像满足后续使用精度要求。
China launched a disaster monitoring constellation satellite recently, called China DMC, which has two remote sensors. Its CCD multi-spectral sensor has a spatial resolution of 32m. This study made some researches on geometric correction method of China DMC remote sensing image. According to its characteristics and later research requirement, a finite element model was adopted to do the correlation and the nearest neighbor method to do the resampling. The precision of the output image can satisfy the later research requirement.
