摘　　要：几何校正为影像预处理工作做了技术准备。其精度直接影响着后续工作的质量。目前,高精度遥感影像因其空间分辨率较高、数据产品格式复杂,在实际应用中对其进行几何精校正(包括正射校正)还存在许多问题。在地面控制点(Ground Control Point,GCP)分布不均或数量不足的情况下,运用空间投影加密控制点的方法,能有效解决此类问题。本文以Quick Bird遥感卫星影像为例,阐述了该方法的可行性。Geometric correction for image preprocessing the technical preparation work. The precision of geometric correction directly affects the subsequent preprocessing the quality of the work. Because of its high spatial resolution,high precision remote sensing image data formats complex products,the current in the practical application of the geometric precision correction（ including orthographical correction） still exist many problems. In the absence of sufficient number and distribution of uniform Ground Control points（ Ground Control Point,GCP）,using the method of space projection encryption Control Point,can effectively solve such problems. With Quick Bird satellite remote sensing image as an example to research and analysis,show that this method is feasible.
