摘要/Abstract

摘要： 针对以航空影像为数据源的矩形建筑物半自动重建进行了研究。采用模型导向的方法，用CSG与B-Rep相结合描述的矩形体基本模型，提取航空影像中建筑物边缘线，人机交互建立建筑物的初始模型；将初始模型反投到影像上，根据建筑物边缘与模型投影线之间套合程度，通过基于广义点摄影测量理论的模型影像匹配算法计算建筑物的精确参数。该方法利用影像上的直线信息进行广义点平差，减少运算量，提高建模效率与建模精度。实验结果证明该方法有较高的准确性。

Abstract: A semi-automatic 3D building modeling method based on aerial images is proposed. Building model is built, building edges are extracted from the aerial images, and the accurate model parameters（position parameters and shape parameters） of buildings are calculated based on generalized point photogrammetry theory. The primitive model of buildings is described by CSG and B-Rep. The initial parameters of model are calculated through human-computer interaction. The initial model is projected to images according to the collinearity equation, and the exact parameters are calculated based on generalized point photogrammetry theory. Experiments are done to prove validity of the algorithm.
