海量控制点影像库系统的设计与实现

摘要

针对海量控制点影像管理现状中的不足,提出了基于数据库方式进行控制点影像管理与应用的新模式,并基于内存动态调度,采用VC6.0平台,实现了控制点影像数据库系统.通过该系统在青海第二测绘局的应用实践表明,该系统能够有效提高控制点影像数据的管理效率,在控制点影像数据的检查、更新以及管理等方面发挥作用.同时,基于数据库方式的控制点影像管理,有益于提高利用控制点对控制点影像匹配的速度,对促进测绘资料的高效利用有着重要意义.%The new mode for control point image management and application based on database is put forward for the deficiency of the current situation of Hailiang control point image management.VC6.0platform is used based on internal storage dynamic scheduling to realize the control point image database system.The application practice of 2nd Institute of Survey & Mapping Qingdao Province shows that this system is able to effectively improve the management effect of the image data in the control point, and it works in the aspects of control point image inspection, update and management, etc.At the same time, the control point image management based on the database facilitates to improve matching speed of the control point by making use of the control point, which has important meaning on promoting the efficient utilization of the surveying & mapping materials.
