First of all, from empirical point of view and through investigation and analysis, it summarizes present conservation conditions and current operation system while preserving historic districts and analyzes exiting problems and the dilemmas encountered with the cases of conservation over the past two decades as background. secondly, through an analysis of aerial elements and conservation operation levels, it develops a systematic view, integration view and synthetic view in conservation of historic districts, utilizing three - fundamental operation theory, constructing a general frame of integration system in conservation of historic districts
首先，以二十余年來歷史街區保護為背景，從實證研究角度出發，通過調研分析總結歷史街區保護現狀和現行運行機制，分析歷史街區保護中存在的問題和面臨的困境；然後，樹立歷史街區保護中的系統觀、整體觀和綜合觀，通過對歷史街區空間要素以及保護運作層次的分析，運用三元運行理論，建構歷史街區保護機制的總體框架。 -
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
提高城市建築物測量過程的自動化程度是目前航空攝影測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測量方法.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，並定義能推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測量位置.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法.實驗結果表明，這種方法與傳統方法相比較，有較高的自動化程度，且測量精度能滿足現有航空攝影測量的要求，有較大的發展和應用潛力
