A New Method for Target Location Fast Correction in Satellite Image
一种卫星遥感图像目标位置快速精校正的新方法

Based on the characteristics of target identification,a new method for target location fast correction in satellite image is proposed in this paper.First,the targets and the nearby ground control points(GCPs) are detected in the satellite image which has been processed with basic geometric correction method.Then the outliers of GCPs are detected.Finally,the geometrical location of the targets are corrected by the GCPs.Also in this paper,a new algorithm based on regional cliques is proposed to automatically detect the outliers of GCPs.The example results indicate that the processing speed for target location correction can be greatly improved and the target location precision can also be ensured.
