原始卫星遥感影像中包含严重的几何变形,几何粗校正不能满足制图要求,必须进行几何精校正。几何精校正依赖一定数量的地面控制点,本文在应用RBN/DGPS采集地面控制点的过程中,结合地理信息系统技术开发了RBN/DGPS导航与数据采集系统,该系统一方面针对手持GPS导航功能的不足,使用基于粗校正遥感影像的导航方式,实现路线导航功能,帮助测量人员准确、快速地找到已设计的控制点,另一方面实现坐标数据采集功能,提出了判断数据稳定性的采集算法并实现了数据的自动处理。
The original satellite remote sensing image contains severe geometric deformation, geometric coarse correction can not meet the cartographic requirements, must be geometric precision correction. In the course of applying RBN / DGPS to collect ground control points, this paper develops a RBN / DGPS navigation and data acquisition system combining with geographic information system technology. This system not only aims at handheld GPS navigation function The navigation method based on the rough corrected remote sensing image is used to realize the route navigation function and help the surveyors to find the designed control points accurately and quickly. On the other hand, the coordinate data acquisition function is proposed and the data collection algorithm And realize the automatic data processing.
