基于华浩超算平台遥感影像几何校正研究——以资源一号02C数据为例

Geometric Rectification of Remote Sensing Images Based on Sinovine SIS Platform:Take ZY-102C Data as Example

对多源遥感影像进行几何校正是遥感影像应用的重要环节,以往的遥感影像利用人工或半自动的方式进行几何校正时,存在校正结果难以预料,控制点精度不可控,二次校正过程中控制点利用效率较低等问题。本文基于以上问题,利用华浩超算平台,对资源一号02C卫星10 m多光谱影像和2.36 m全色影像进行几何校正。试验证明华浩超算平台的实时几何校正模块,可以对每一个精校正后控制点的精度进行实时控制,并有效地解决了控制点利用效率低的问题。

For geometric correction is an important part of application of multi - source remote sensing image, using manual or semi - automatic mode geometric correction in the past, the correction Imaging results are unpredictable, not to achieve a control points and not to control points accuracy, as well as in the process of the second correction efficiency is low of control points . On the basis of these questions, this paper using the data of 02C satellite of 10m muhispectral image and 2.36m full color images made geometric cor- rection based on SinovineSIS platform. Test shows real - time geometric correction module of the SinovineSIS platform, for every fine point accuracy after correction for real - time control, and solves the problem of inefficient use of control points.
