|
摘要
主要研究了空中三角测量中像片及像片连接点拓扑关系的矩阵表示算法及其应用。像片连接点自动匹配和区域网平差是空中三角测量的主要内容,像片及像片连接点的拓扑关系是自动匹配和区域网平差高效处理的关键。据此,从导航GPS数据生成的航线图出发,提出并研究了基于8邻域算法的像片连接点矩阵生成方法,完成了用二维矩阵表示像片连接点点号和点名,并通过该矩阵完成了像片连接点自动匹配中同名像点自动查找和区域网平差中地面加密点自动查找的方法。研究成果对于提高自动空中三角测量存储效率和区域网平差速度有积极意义。
The matrix algorithm and its application in Aerialtriangulation based on the topological relationship ofimagetie points is focused on.The automatic matching of image tie points and regional network adjustment are the main contents of Aerialtriangulation.The topological relationship of image tie points is the key to efficient processing of automatic matching and regional network adjustment.Based on the route map generated by the airborne GPS data,a method for generating aimage tie points matrix by the 8-neighborhood algorithm is proposed,and the point ID as well as point name of the image tie points by the two-dimensional matrix is represented.The matrix can automatically find corresponding image points and the photogrammetric point in the regional network adjustment.This results have a positive significance for improving the storage efficiency of automatic aerialtriangulation and speed of regional network adjustment.
