园林建筑、建筑、屋宇装备、建筑物测量、工料测量及结构工程 - The improvement on the process of automatically measuring city buildings is one of the most important problems in the current aerial photographic measurement . an approach to measuring a city building based on its structure information is presented . a city building ' s ideal model is first represented by some independent parameters according to its structure information and some image variants which can induce model parameters are defined , and then the initial value of image variants are acquired by combining all kinds of information in the left and right images . finally the optimal location of the building is found for some certain criteria . an implementation of this method is illustrated on flat - roof and rectangular buildings in detail . the experimental results show that not only the method is more automatic than existing methods but also the precision of measurement can satisfy the acquirement of the current aerial photographic measurement , and confirm the method has a good developmental and applied potential
提高城市建筑物测量过程的自动化程度是目前航空摄影测量研究的主要问题之一.文中提出了一种基于结构信息的城市建筑物测量方法.首先根据城市建筑物的结构信息，用几个相互独立的参数来描述建筑物的理想模型，并定义能推导出模型参数的图像变量，然后组合利用左右图像中各种信息获得图像变量的初始值，最后在一定准则下寻求城市建筑物的最佳测量位置.该文以平顶矩形建筑物为例详细讨论了它的一种实现算法.实验结果表明，这种方法与传统方法相比较，有较高的自动化程度，且测量精度能满足现有航空摄影测量的要求，有较大的发展和应用潜力
