利用地图与单影像进行建筑物三维重建的新途径

A New Method for Building Reconstruction Based on Vector Map and Non-metric Camera Image

摘要: 首先利用直接线性变换(DLT)、单影像空间后方交会确定影像方位元素的初值,然后利用影像上全部建筑物的直线(特别是建筑物的铅垂线)来确定影像方位元素的精确值,以达到对多栋建筑物同时建模的目的。

Abstract: This paper presents an algorithm to compute initial values of camera’s orientation elements and height of building with the technique of CSG, DLT and space resection of a single image. With all lines of buildings on image (especially plumb lines of buildings), camera’s orientation elements can be more precise and complete building reconstruction.
