摘　　要：利用像素工厂系统对一个包含23对SPOT-5影像镶嵌图项目进行快速制作,但由于空三处理失误导致其中2景影像配准精度差而出现像素错位。为避免返工、有效弥补镶嵌影像图的局部几何问题,本文采用了局部修正方法,最终实现及时向客户提交质量合格的产品。A large size remote sensing image mapping project is to produce mosaic map with 23 pairs of SPOT - 5 images rapidly using pixel factory system. A serious problem is that there are some distorted pixels in mosaic map due to low registration precision between 2 pairs of synchronous images, the reason is that a mistake was made by someone dur- ing aerial triangulation process. To solve this problem and submit product to customer on time, this paper adopts a partial correction to mosaic map method and finally it success.
