A two-step rectification algorithm for airborne linear images with POS data     

庹红娅  刘允才 《浙江大学学报(A卷英文版)》2005,6(6):492-496

INTRODUCTION Image rectification is an important preprocessingstep in many fields, such as computer vision, remotesensing, data fusion and classification; and had beenstudied by many researchers (Hartley, 1999; Fusielloand Trucco, 2000; Dong and Wang, 2000; Chen et al.,2003). There are severe distortions in airborne linearimages because of the ununiformity and turbulence ofthe velocity, the gradient, and the altitude of the air-plane during flight. These data can only be useful ifthey …  相似文献   

某地铁车站施工期间交通组织方案探讨     

宋梦  胡长明  刘允才 《中国科技信息》2011,(16):53-54

以郑州市轨道交通一号线某站点为实例,针对该站点施工期间遇到的实际交通问题,深入研究其施工方案如何选取及临时路面系统交通导改的选取方式及特点。通过考察借鉴一些既有城市轨道交通站点施工的交通疏解实际情况制定出该站点的交通疏解施工时应遵循的基本原则,并将整个交通疏解分三个阶段实施,解决了快速公交顺利通行的问题。施工时制定了合理的疏解方案,并简单说明了方案的实施效果,证明了方案的可行性。  相似文献
