  7. 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

    提高城市建築物量過程的自動化程度是目前空攝影量研究的主要問題之一.文中提出了一種基於結構信息的城市建築物量方.首先根據城市建築物的結構信息,用幾個相互獨立的參數來描述建築物的理想模型,並定義能導出模型參數的圖像變量,然後組合利用左右圖像中各種信息獲得圖像變量的初始值,最後在一定準則下尋求城市建築物的最佳置.該文以平頂矩形建築物為例詳細討論了它的一種實現演算.實驗結果表明,這種方與傳統方相比較,有較高的自動化程度,且量精度能滿足現有空攝影量的要求,有較大的發展和應用潛力
